The slaughter of horses for meat is not only unnecessary and inhumane, it is also harmful to humans as well as horses in many ways.

Canada Horse Slaughter Industry

Statistics Canada reports that Canada’s total horse meat exports bring in roughly $80 million per year. Canada slaughtered 66 651 horses in 2014, in five slaughter plants across the country.

As of 2009, approximately 100,000 horses are slaughtered in Canada each year to produce meat for human consumption, most of which is exported to European countries. This figure has doubled since operations at American horse slaughter plants were suspended in recent years. The BC SPCA and the Canadian Federation of Humane Societies have presented federal authorities with a report of concerns regarding horse slaughter in Canada. The Report on Horse Slaughter Practices in Canada  is based on a review of recent video footage depicting inhumane practices at two of Canada’s largest horse slaughter plants, one in Alberta and one in Quebec.

“At one “kill” auction attended by Star reporters last Friday, more than 60 horses were crammed into pens without hay or water in temperatures topping 35 degrees Celsius.

Dirty little secret: Canada’s slaughter industry under fire

A year before the last U.S. horse plant shut down in 2007, Canada slaughtered about 50,000 horses. Since then, the number of horses killed annually has nearly doubled to between 90,000 and 113,000 over the past three years. Star reporters tail a transport truck filled with horses bought at a U.S. ‘kill’ auction, bound for slaughter – and dinner – in Quebec.”

The Facts About Horse Slaughter

 

Eastern Grey Squirrel

Eastern Grey Squirrel (Sciurus carolinensis)

By Jasper Tapen    Nov/13/2014

Introduction

Many of the different names are given to the eastern grey squirrel, such as Bannertail and Silvertail grey squirrel depending on region, Latin name Sciurus carolinensis comes from two Greek words, skia, meaning shadow, and oura, meaning tail.

Description

The head and body length is from 23 to 30 cm (9.1 to 11.8 in), the tail from 19 to 25 cm (7.5 to 9.8 in) and the adult weight varies between 400 and 600 g (14 and 21 oz.).  Eastern gray squirrel commonly occurs in two colors, grey and black Gray individuals are predominantly gray, but it can have a brownish color with white underside. Black individuals are generally a glossy uniform black. Genetic variations within grey squirrels include individuals with black tails and black-colored squirrels with white tails,  or reddish color phase and some animals may also have a combination of colors for example a black body with a red tail. Albino eastern grey squirrels also occur and also completely white populations are found.

The most prominent physical feature of the eastern grey squirrel is its large bushy tail which it uses for balance, as a warm covering during the winter months and perhaps as a sunshade in summer. Tail can be used to distract pursuing predators. It acts as a shock absorber when the animal jumps from high places.

Distribution

Sciurus carolinensis is native to the eastern and Midwestern United States, and portions of the eastern Canada. The eastern gray squirrel in Canada is found from New Brunswick to Manitoba, in USA from East Texas to Florida,

In Europe is a concern because they have displaced some of the native squirrels prolific and adaptable species, they out-compete the native reds for food, feeding more at ground level and being able to digest acorns, which the reds can’t. European Union has expressed concern it will similarly displace the red squirrel from parts of the European continent.

The eastern gray squirrel has been introduced to Ireland, Italy, South Africa and Australia.

Diet

Eastern gray squirrels eat a wide range of foods, such as tree bark, tree buds, berries, many types of seeds and nuts (acorns, hickory nuts, walnuts, beechnuts and pecans), some types of fungi found in the forests, including fly agaric mushrooms (Amanita muscaria). They can cause damage by tearing the tree bark and eating the soft cambial tissue underneath. In Europe, sycamore (Acer pseudoplatanus) L. and beech (Fagus sylvatica L.) suffer the greatest damage.

Eastern gray squirrels have a high enough tolerance for humans to inhabit residential neighborhoods and will raid bird feeders for millet, corn, and sunflower seeds. They will also raid gardens for tomatoes, corn, strawberries, and other garden crops. On very rare occasions, when their usual food sources are scarce, eastern gray squirrels will also prey upon insects (adults and larvae), frogs, small rodents including other squirrels, and small birds, their eggs and young. They will also gnaw on bones, antlers, and turtle shells – likely as a source of minerals sparse in their normal diet.

Behavior

Squirrels are tree-dwelling rodents they are agile climbers and jumpers with keen senses of sight, smell, and hearing and are alert, nervous and wary, especially on the ground. They live in urban areas and in woodland areas. Eastern gray squirrels prefer constructing their dens upon large tree branches and within the hollow trunks of trees. They also have been known to take shelter within abandoned bird nests in urban areas squirrels build a type of nest, known as a “drey”, in the forks of trees, consisting mainly of dry leaves and twigs. Males and females may share the same nest for short times during the breeding season and during cold winter spells squirrels may share a drey to stay warm. They may also nest in the attic or exterior walls of a house.

Grey Squirrel is mostly active during daylight, although it can sometimes be seen feeding by the light of a full moon. In summer, activity is greatest early in the morning and in mid-afternoon. Unlike a lot of other squirrels, eastern grey squirrels do not hibernate and in winter are most active around midday taking advantage of the warmest temperatures.

Reproduction:

Eastern gray squirrels can breed twice a year, but younger and less experienced mothers will normally have a single litter per year in the spring. Depending on abundance of food, older and more experienced females may breed again in summer. In a year of abundant mast crop 36% of females will bear two litters, but none will do so in a year of poor mast crop. Their breeding seasons are December to February and May to June, though this is slightly delayed in more northern latitudes. The first litter is born in February or March, the second in June or July. Birthing may be advanced or delayed by a few weeks depending on climate, temperature and forage availability. In any given breeding season an average of 61 – 66% of females will bear young. If a female fails to conceive or loses her young to unusually cold weather or predation, she will re-enter estrus and have a later litter. Normally, one to four young are born in each litter, but the largest possible litter size is eight. The gestation period is about 44 days. The young are weaned at around 10 weeks, though some may wean up to six weeks later in the wild. They begin to leave the nest after 12 weeks, with autumn born young often wintering with their mother. Only one in four squirrel kits will survive to one year of age, with mortality of around 55% for the following year. Mortality rates then decrease to around 30% for following years until they increase sharply at eight years of age.

A litter of gray squirrels may contain both black and grey individuals and all shades between black, grey and red.

Eastern gray females can rarely enter estrus as early as five and a half months old, but females are not normally fertile before at least one year of age. Male Eastern Greys are sexually mature between one and two years of age. These squirrels can live to be 20 years old in captivity, but in the wild live much shorter lives due to predation pollution and the challenges of their habitat.

Predation

Predators include humans, hawks, weasels, raccoons, foxes, domestic and feral cats, snakes, owls, coyotes, wolves and dogs. In its introduced range in South Africa it has been preyed on by African harrier-hawks.

Gray squirrels were eaten in earlier times by Native Americans and their meat is still popular with hunters across most of their range in North America. Today, it is still available for human consumption and is occasionally sold in the United Kingdom

Unique Adaptetions

The eastern gray squirrel is one of very few mammalian species that can descend a tree head-first. It does this by turning its feet so the claws of its hind paws are backward pointing and can grip the tree bark.

Squirrels can lose its tail sheath and some bones to escape a predator’s grasp they can run reaching speeds of up to 25 km per hour on the ground.

Keystone Species

Keystone Species

By Jasper Tapen    Nov/10/2014

Definition of keystone species: described as species that is playing a unique and critical role in maintaining the structure and balance of an ecosystem, if a keystone species is removed ecosystem may experience a dramatic shift even though that species was a small part of the ecosystem by measures of biomass or productivity. Just like keystone in an arch’s crown, keystone species play the same role in many ecological communities by maintaining the structural integrity of the community. Since the prey numbers are low, the keystone predator numbers can be even lower and still be effective. Yet without the predators, the herbivorous prey would explode in numbers, wipe out the dominant plants, and dramatically alter the character of the ecosystem. The exact scenario changes in each example, but the central idea remains that through a chain of interactions, a non-abundant species has an out-sized impact on ecosystem functions. Keystone species theory remains a young theory and the underlying concepts and is still in developing stages. It takes a great deal of study for scientists to understand the complexities and nuances of ecosystems and their keystone species, and there is still much work to be done.

History

Robert T. Paine, a professor of zoology at the University of Washington, proposed the keystone species concept, using Pisaster ochraceus, a species of starfish, and Mytilus californianus, a species of mussel as a primary example. In his 1966 paper, Food Web Complexity and Species Diversity, Paine described such a system in Makah Bay in Washington, Professor Paine follow-up in his 1969 paper where he introduced the term keystone species. Keystone species play important role in keeping out new plants or animals that could come into the habitat and push out the native species.

Keystone species concept originally referred specifically to a predator. However, other species can play the same role by definition of Power et al. implies that keystone species can exert their influence through other interactions as well for example ecosystem engineers, pollinators and mutualist. Other example, diseases that have strong impacts on their hosts would also be classic examples of keystone species under the broad definition of Power et al., since the disease organisms generally have a very small biomass in the system. For example, an outbreak of rinderpest in the late 19th century in southern Africa had a catastrophic impact on ungulates, and their loss cascaded to cause a fundamental transition in the African landscape, from grassland to woody savannah. Sugar maple good example of plant as keystone species, this tree is a keystone species of the hardwood forest. It brings water from lower levels in the ground that helps other plants. It is also home to many insects, birds, and small animals.

                                                                     Predators

In most cases is a small predator that prevents a particular herbivorous species from eliminating dominant plant species. Declines of relatively rare top predators like wolf and cougars in terrestrial ecosystems have allowed populations of herbivores such as white-tailed deer to explode, with devastating impacts on the biomass and species composition of terrestrial vegetation. Keystone predators don’t need to be apex predators (Sea stars are prey for sharks, rays, and sea anemones. Sea otters are prey for orca.) A Classic Keystone Species is Sea Otters they are keystone species in the kelp forests. They eat many invertebrates, but especially sea urchins. If there are too many sea urchins, they will eat too much of the kelp and destroy it.

                                                                      Mutualists

Keystone mutualists are organisms that participate in mutually beneficial interactions, for example, there is a period of each year when Banksia prionotes (Acorn Banksia) is the sole source of nectar for honeyeaters, which play an important role in pollination of numerous plant species. Therefore the loss of this one species of tree would probably cause the honeyeater population to collapse, with profound implications for the entire ecosystem. Another example is frugivores such as the cassowary, which spreads the seeds of many different trees, and some will not grow unless they have been through a cassowary.

Pollinators

The critical importance of pollination has been recognized since humans first gave up nomadic lifestyles. Bees are considered keystone species, by pollinating plants, bees contribute to their survival. The plants are shelter for insects, which are then eaten by other species, like birds. Pollination is the reason hummingbirds are a keystone species. In places where the numbers of hummingbirds are low, other species of plants will take over the ecosystem.

   Engineers

Prairie dog is one of keystone species they make burrows and provide nesting areas for Mountain Plovers and Burrowing Owls. Prairie dog tunnel systems also help channel rainwater into the water table to prevent runoff and erosion, and can also serve to change the composition of the soil in a region by increasing aeration and reversing soil compaction that can be a result of cattle grazing. Prairie dogs also trim the vegetation around their colonies, perhaps to remove any cover for predators. Another well-known ecosystem engineer and keystone species is the beaver, which transforms its territory from a stream to a pond or swamp. Beavers affect the environment first altering the edges of riparian areas by cutting down older trees to use for their dams. This allows younger trees to take their place. Beaver dams alter the riparian area they are established in. Depending on topography, soils, and many factors, these dams change the riparian edges of streams and rivers into wetlands, meadows, or riverine forests. These dams have shown to be beneficial to myriad species including amphibians, salmon, and song birds.

Conservation efforts tend to focus on the preservation of keystone species to stabilize the entire biological community, as the loss or decline of a keystone species within an ecosystem has serious consequences for the continued productivity, structure and function of the ecosystem.

                                                          Things to think about…….

According to noted biologist E.O. Wilson, we are now seeing species extinctions at 1,000 times the normal rate, and there is no disagreement among biodiversity scientists that this is human-caused. How many of these lost species will turn out to have been keystone species?

How much habitat change can our natural world withstand before a domino effect causes truly disastrous results?

WINTER BIRD FEEDING 101

WINTER BIRD FEEDING

WINTER BIRD FEEDING 101

By jasper Tapen: 7 November 2014

A big winter storm, with deep snow or ice cover, cuts off many birds from their natural food supplies and can actually cause them to starve. Backyard bird feeding can help your feathered friends and make real contribution to their survival and even thriving during the winter months. Offer a variety of food to attract different species of birds.

Types of Food (best for winter)

  • You can create your own seed mixes by combining any number of seeds or add fruit and bakery products to your winter feeding arsenal. You can add menu by offering chopped nuts, doughnuts, popcorn, bakery crumbs, grapes, raisins, apple pieces and orange halves. Treat your birds to some home cooking by making muffins, bread and other snacks with sunflower seeds and nuts. Avoid preservatives and artificial colors and flavors.
  • Sunflower seed is a very nutritious source of high quality protein and oil, sunflower seed or mixed seed are popular for use in these feeders and will attract many songbirds such as cardinals, finches, and chickadees. The outer shell of black oil sunflower seeds are thinner and easier to crack than other types of sunflower seeds. In addition, the kernel is larger than striped or white sunflower seeds. Black Oil Sunflower seeds also contain a large amount of fat; therefore they are especially good to use in the winter.
  • Cracked corn: Sparrows, blackbirds, jays, doves, quail, and squirrels are just a few of the creatures you can expect at your feeders if you feed cracked corn. Depending on where you live you may also get turkeys, deer, elk, moose, and caribou. Fed in moderation, cracked corn will attract almost any feeder species.
  • Suet is raw beef fat from around the kidneys and loins. Suet is one of the best foods to attract nuthatches, woodpeckers, wrens, titmice, creepers, kinglets, chickadees, thrashers, cardinals and even bluebirds.

Different designs and types of feeders

  • Seed feeders: These are the most common type and can vary in design from tubes to hoppers and trays.
  • Suet feeders
  • Platform Feeders

Tips and Tricks

  • Consider moving your feeders in a more sheltered location for the winter, strong winds are uncomfortable for birds . Surrounding your feeders with trees and shrubs can help buffer your birds and creating a milder micro climate. Avoid wide open areas in your backyard, place your feeder near bushes trees like pine or outdoor structures where birds can escape from predators and get shelter from elements.
  • Place the feeder in an undisturbed location in your yard away from traffic, noise and interruption from people or pets.
  • Proper positioning of feeders is very important to reduce crowding and window collisions.
  • Collisions with windows can be reduced by window decals or wooden lattice.
  • Water source is also important need along with bird food. Use heated birdbaths during winter if possible.
  • Regular disinfecting of feeders and watering stations is critical for birds overall health. Make sure that feed has not become moldy or rancid and water fresh.
  • To start you should not completely fill a feeder at first. The food will get old and spoil if it is left uneaten for too long, once the birds begin taking food, the feeder should be kept full.
  • Don’t buy bags of mixed birdseed is not a bargain because they contain a lot of filler seeds such as red millet.
  • Ground feeding birds will welcome seed sprinkled on the snowy ground where it is easily found.
  • Keeping couple of bags in the trunk of your car is good idea. The extra weight will give you added traction when the roads are slick, and you’ll always have a ready supply on hand for your hungry friends in need.

Ideas how you help

  • Christmas tree: Instead of throwing out throw it on the ground where it can offer shelter to birds.
  • Take old shrubbery branches or logs and pile them up! Many birds will appreciate the extra cover. Juncos, towhees and sparrows will appreciate keeping snug during cold winter nights.

Potential Risks

  • Environmental Problems: The house sparrow population can become inflated locally where feeders are used. In North America, where the house sparrow is an invasive species, competition from house sparrows can exclude the indigenous bluebirds from available nest sites as well as attack indigenous birds.
  • Fostering Dependency:
  • Spread of Disease: Birds may contract and spread disease by gathering at feeders, poorly maintained feeding and watering stations may also cause illness.
  • Risk of Predation: Birds at feeders risk predation by cats and other animals, or may incur injury by flying into windows.

Riparian zones and Benefits of Riparian Zones

??????????????

Riparian zones

Benefits of Riparian Zones

The biologically distinctive area that borders the waterfront is called the “riparian zone.”

Ecosystem conservation

Riparian zones are an extremely important component of most ecosystems. Riparian zones provide a variety of ecosystem services including sediment filtering, bank stabilization, water storage and release, and aquifer recharge. In addition, riparian zones provide important habitat for wildlife. The riparian zone acts as a natural sponge, soaking up water as it runs off the land, and slowly releasing that water back into the stream. Riparian vegetation and litter reduces erosion and regulates the overland flow of water to the stream (uplands vegetation serves this function, too).

Fish habitat

Streams flowing through healthy riparian zones are superior habitat for fish because  the riparian trees provide shade and buffer temperatures,  inputs of woody debris creates fish habitat, inputs of organic matter via leaf fall provides food sources for invertebrates and fish, and invertebrates that fall into the stream from the surrounding riparian vegetation provides food for other organisms. In addition, the riparian zone can improve the water quality of the stream by filtering out nutrients that would otherwise enter the stream. Riparian vegetation contributes shade, food and shelter for aquatic organisms. The riparian zone is also home to many animals that move between land and water, such as insects, amphibians and waterfowl.

Wildlife habitat

The abundance and diversity of wildlife in an area is influenced by the availability of water, the productivity (amount of carbon fixed by photosynthesis) and habitat diversity. Riparian zones provide reliable sources of water for wildlife and the greater productivity allowed by the high moisture content of the soil allows for more potential food for wildlife. In addition, the habitat diversity of riparian vegetation provides many potential niches for wildlife to fill. Not surprisingly, the diversity and abundance of wildlife in riparian zones is higher than in adjacent communities, particularly in arid regions.

Threats to riparian zones:

  • Road building may cause accelerated erosion, introduce oil and other pollutants to the stream, cut off subsurface water flow to the stream and threaten wildlife.
  • Farming can increase erosion of stream banks if the riparian zones are cleared for more farmland. Farmland is lost where the erosion occurs and sedimentation increases downstream. More farmers now maintain the health of their riparian areas to ensure long-term sustainability of their land. Worldwide, more than 99.7% of human food (calories) comes from the land. Serious environmental impacts, such as soil erosion, water pollution from surface runoff, and pesticide pollution, result from fossil fuel-intensive agriculture. A critical need exists to assess fossil energy limits, the sustainability of agriculture, and the food needs of a rapidly growing world population.
  • Grazing or overgrazing of the riparian zone can cause changes in the types of vegetation and the amount of cover and forage, increase erosion, and introduce increased amounts of nutrients and fecal coliform bacteria to the stream through manure. However, if cattle are managed correctly (herded or fenced out after a short time) they can be a part of a healthy riparian zone. Manifestations of overgrazing in landscapes composed largely of native species include reduction of species richness, loss of biodiversity, desertification, loss of native topsoil and increases in surface runoff. In fact, overgrazing can be considered the major cause of desertification in arid drylands, tropical grasslands and savannas, worldwide. Overgrazing of historic human-created pastureland, especially irrigated or non-native grasslands, may lead to soil compaction, reduction in long-term grazing productivity and loss of topsoil.
  • Development of riparian zones for housing or commercial development often causes removal of vegetation and alters the stream banks. These changes can increase the intensity of floods, increase the direct input of pollutants to water, and decrease wildlife.
  • Logging operations today realize the importance of healthy riparian zones and rarely log them. However, logging roads continue to be built through these zones, creating the same problems that all roads do. When upland vegetation is stripped away, too much water is allowed to flow down into the stream at one time, which can lead to bank erosion, deep and narrow channels, shrunken riparian zones, and often increased loads of sediments.
  • Dams reduce downstream flooding. while this serves the people who live downstream in the floodplain, it degrades riparian zones. Natural flood cycles are critical to healthy riparian zones. Floods bring essential supplies of water, nutrients and sediment. They also help to create backwater that serve as critical fish nurseries.

Black squirrel

??????????????

Black squirrel

The black squirrel is a melanistic subgroup of the eastern gray squirrel. Melanism is a development of the dark-colored pigment melanin in the skin or its appendages and is the opposite of albinism. Historically, it was also the medical term for black jaundice. The word melanism is deduced from the Greek: μελανός, meaning “black pigment”.

There are also pure white and pure black squirrels but both are variations of the gray squirrel.”  Biologists surmise that the black fur more readily absorbs the rays of the sun, thereby keeping its owner warmer during cold winters. Selective genetics has given the black squirrel this survival advantage.

As a melanistic variety of the eastern gray squirrel, individual black squirrels can exist wherever grey squirrels live. Grey mating pairs cannot produce black offspring. Gray squirrels have two copies of a normal pigment gene and black squirrels have either one or two copies of a mutant pigment gene. If a black squirrel has two copies of the mutant gene it will be jet black. If it has one copy of a mutant gene and one normal gene it will be brown-black. In areas with high concentrations of black squirrels, mixed litters are common. The black subgroup seems to have been predominant throughout North America prior to the arrival of Europeans in the 16th century, as its dark color helped them hide in old growth forests which tended to be very dense and shaded. As time passed, hunting and deforestation led to biological advantages for grey coloured individuals. Today, the black subgroup is particularly abundant in the northern part of the eastern gray squirrel’s range. This is likely due to the significantly increased cold tolerance of black squirrels which lose less heat than greys. Black squirrels also enjoy concealment advantages in denser northern forests.

Distribution

Large natural populations of black squirrels can be found throughout Ontario and in several parts of Ohio, Maryland, Michigan, Indiana, Virginia, Washington, D.C., Wisconsin, Minnesota, and Pennsylvania. Populations of grey squirrels in which the black subgroup is predominant can be found in these six areas as well as in smaller enclaves in Missouri, New Jersey, Delaware, southern New York, Illinois and Connecticut

Large increase in our rodent population makes us a prime hangout for Eagles, Red-tailed Falcons and the like, as well as the Wiley Fox and other fleet of foot predetators which keeps natures balance in the proper order.

Sleeping Habits of Horses

???????????????

Sleeping Habits of Horses

If you give your horse opportunity for rest he will give you the performance of a life- time.

Horses can sleep both standing up and lying down. They can doze and enter light sleep while standing, an adaptation from life as a prey animal in the wild. Lying down makes an animal more vulnerable to predators. Horses are able to sleep standing up because a “stay apparatus” in their legs allows them to relax their muscles and doze without collapsing. In the front legs, their equine forelimb anatomy automatically engages the stay apparatus when their muscles relax. The horse engages the stay apparatus in the hind legs by shifting its hip position to lock the patella in place. At the stifle joint, a “hook” structure on the inside bottom end of the femur cups the patella and the medial patella ligament, preventing the leg from bending.

Horses do not need a solid unbroken period of sleep time. They obtain needed sleep by many short periods of rest. This is to be expected of a prey animal that needs to be ready on a moment’s notice to flee from predators. Horses may spend anywhere from four to fifteen hours a day in standing rest, and from a few minutes to several hours lying down. However, not all this time is the horse asleep; total sleep time in a day may range from several minutes to two hours. Horses require approximately two and a half hours of sleep, on average, in a 24-hour period. Most of this sleep occurs in many short intervals of about 15 minutes each. Most horses will lie down for a brief rest every day if they have a comfortable place to do so. Some will become so relaxed that they twitch and snore, just like a dog. Each horse has its own sleeping habits. Some will sleep only at night while others sleep during the day as well.

Horses must lie down to reach REM (Rapid Eye Movement) sleep. They only have to lie down for an hour or two every few days to meet their minimum REM sleep requirements.  However, if a horse is never allowed to lie down, after several days it will become sleep-deprived, and in rare cases may suddenly collapse as it involuntarily slips into REM sleep while still standing.  This condition differs from narcolepsy, which horses may suffer from.

Michael Lowder, DVM, MS a renowned equine practitioner from the University of Georgia who wrote the following:

“Do horses sleep? Have you ever noticed that there are days when your horse appears more rested than others? We all know how a good bed affects our sleep, and recent research indicates that the bedding material we provide our horses may influence their sleep as well!  Our horses spend most of their lives in an artificial environment, and tradition along with myth dictates how we manage their lives. We often create the horse’s environment from a human point of view without giving much thought to what our horses really need. So what bedding should you use? Think about it when you want your horse to perform at his best, you must give him the opportunity to rest and a good bed to sleep in.”

Honey bee

Honey bees

Honey bee facts

A honey bees or honeybee is any member of the genus Apis, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests from wax. Honey bees are the only extant members of the tribe Apini, all in the genus Apis. Currently, only seven species of honey bee are recognized, with a total of 44 subspecies.  Historically from six to eleven species have been recognised. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. Some other types of related bees produce and store honey, but only members of the genus Apis are true honey bees. The study of honey bees is known as apiology.

Two species of honey bee, A. mellifera and A. cerana indica, are often maintained, fed, and transported by beekeepers. Modern hives also enable beekeepers to transport bees, moving from field to field as the crop needs pollinating and allowing the beekeeper to charge for the pollination services they provide, revising the historical role of the self-employed beekeeper, and favoring large-scale commercial operations.

Africanized bees (known colloquially as “killer bees”) are hybrids between European stock and one of the African subspecies A. m. scutellata; they are often more aggressive than and do not create as much of a surplus as European bees, but are more resistant to disease and are better foragers. Originating by accident in Brazil, they have spread to North America and constitute a pest in some regions. However, these strains do not overwinter well, so are not often found in the colder, more northern parts of North America. The original breeding experiment for which the African bees were brought to Brazil in the first place has continued (though not as intended). Novel hybrid strains of domestic and redomesticated Africanized bees combine high resilience to tropical conditions and good yields. They are popular among beekeepers in Brazil.

Lifecycle

As in a few other types of eusocial bees, a colony generally contains one queen bee, a fertile female; seasonally up to a few thousand drone bees, or fertile males; and tens of thousands of sterile female worker bees. Details vary among the different species of honey bees, but common features include:

  1. Eggs are laid singly in a cell in a wax honeycomb, produced and shaped by the worker bees. Using her spermatheca, the queen actually can choose to fertilize the egg she is laying, usually depending on into which cell she is laying. Drones develop from unfertilised eggs and are haploid, while females (queens and worker bees) develop from fertilised eggs and are diploid. Larvae are initially fed with royal jelly produced by worker bees, later switching to honey and pollen. The exception is a larva fed solely on royal jelly, which will develop into a queen bee. The larva undergoes several moultings before spinning a cocoon within the cell, and pupating.
  2. Young worker bees clean the hive and feed the larvae. When their royal jelly-producing glands begin to atrophy, they begin building comb cells. They progress to other within-colony tasks as they become older, such as receiving nectar and pollen from foragers, and guarding the hive. Later still, a worker takes her first orientation flights and finally leaves the hive and typically spends the remainder of her life as a forager.
  3. Worker bees cooperate to find food and use a pattern of “dancing” (known as the bee dance or waggle dance) to communicate information regarding resources with each other; this dance varies from species to species, but all living species of Apis exhibit some form of the behavior. If the resources are very close to the hive, they may also exhibit a less specific dance commonly known as the “round dance”.
  4. Honey bees also perform tremble dances, which recruit receiver bees to collect nectar from returning foragers.
  5. Virgin queens go on mating flights away from their home colony to a drone congregation area, and mate with multiple drones before returning. The drones die in the act of mating. Queen honey bees do not mate with drones from their home colony.
  6. Colonies are established not by solitary queens, as in most bees, but by groups known as “swarms”, which consist of a mated queen and a large contingent of worker bees. This group moves en masse to a nest site scouted by worker bees beforehand. Once they arrive, they immediately construct a new wax comb and begin to raise new worker brood. This type of nest founding is not seen in any other living bee genus, though several groups of vespid wasps also found new nests by swarming (sometimes including multiple queens). Also, stingless bees will start new nests with large numbers of worker bees, but the nest is constructed before a queen is escorted to the site, and this worker force is not a true “swarm”.

In cold climates, honey bees stop flying when the temperature drops below about 10 °C (50 °F) and crowd into the central area of the hive to form a “winter cluster”. The worker bees huddle around the queen bee at the center of the cluster, shivering to keep the center between 27 °C (81 °F) at the start of winter (during the broodless period) and 34 °C (93 °F) once the queen resumes laying. The worker bees rotate through the cluster from the outside to the inside so that no bee gets too cold. The outside edges of the cluster stay at about 8–9 °C (46–48 °F). The colder the weather is outside, the more compact the cluster becomes. During winter, they consume their stored honey to produce body heat. The amount of honey consumed during the winter is a function of winter length and severity, but ranges in temperate climates from 15 to 50 kg (30 to 100 pounds).

Ecosystem-based approach to science policy for biodiversity

The study and management of ecosystems represents the most dynamic field of contemporary ecology, it is key inthe context of sustainable development.  UNESCO’s programmes ensure a sustainable resources management via research, conservation and information sharing.

In particular, the Man and the Biosphere programme ecosystem and theme-specific networks provide valuable insights into sustainable development models and climate change mitigation and adaptation possibilities. They include networks and research, capacity building and educational collaborations.

Marine, coastal and island areas

MAB network and activities

UNESCO’s Man and the Biosphere Programme activities span protection, scientific research and human use.

Small Island Developing State: Biodiversity Resources

Activities addressing biodiversity conservation in SIDS.

IOC Coastal Area Management activities

The objective for this programme is to assist IOC Member States in their efforts to build marine scientific and technological capabilities in the field of Integrated Coastal Management as follow up of UNCED, Agenda 21. The programme will provide reliable marine scientific data, develop methodologies, disseminate information and build interdisciplinary capacity through symposia, workshops, seminars and training courses.

PEGASO Project

This EU project focuses on Integrated Coastal Zone Management in the Mediterranean and the Black Sea. IOC/UNESCO is one of the key partners of PEGASO; it is responsible for the coordination of one of the most important foreseen outcomes of PEGASO, a Regional Assessment of the Mediterranean and Black Sea.

Mountains

MAB network and activities

Mountain regions represent about one quarter of the Earth’s terrestrial surface, and are home to approximately 25% of the global population. Mountains are crucial for life. They offer a wealth of ecosystem functions and services (freshwater, biodiversity, forest products, minerals, habitats for threatened species), and landscapes and cultures of exceptional value.

Forests

MAB networks and activities on tropical forests

Most of the world species live in forests and in particular in tropical forests. Although some of these creatures are not obvious to all, e.g. insects, fungi and lower life forms, they play a critical role. The rapid disappearance of tropical forest and their biodiversity involves a wide range of changes, well beyond the known crucial interactions between forest cover and climate.

Indigenous Conservation and Management

The recognition that local and indigenous people have their own ecological understandings, conservation practices and resource management goals has important implications. It transforms the relationship between biodiversity managers and local communities

The World Heritage Forest Programme

World Heritage forest sites now have a total surface area of over 75 million hectares and represent over 13% of all IUCN category I-IV protected forests worldwide.The World Heritage Convention is uniquely positioned amongst international conventions, programmes and agencies to play a leading role for in-situ conservation of forest biodiversity.

Leopard facts

African leopard, Amur leopard,  Persian leopard, Indian leopard, Northern Chinese leopard, Sri Lankan Leopard, Himalayan Leopard.

The leopard /ˈlɛpərd/ (Panthera pardus) is one of the five “big cats” in the genus Panthera. It is a member of the Felidae family with a wide range in some parts of sub-Saharan Africa, West Asia, the Middle East, South and Southeast Asia to Siberia.

Compared to other members of the Felidae, the leopard has relatively short legs and a long body with a large skull. It is similar in appearance to the jaguar, but is smaller and more slightly built. Its fur is marked with rosettes similar to those of the jaguar, but the leopard’s rosettes are smaller and more densely packed, and do not usually have central spots as the jaguars do. Both leopards and jaguars that are melanistic are known as black panthers.

The species’ success in the wild is in part due to its opportunistic hunting behavior, its adaptability to habitats, its ability to run at speeds approaching 58 kilometres per hour (36 mph), its unequaled ability to climb trees even when carrying a heavy carcass, and its notorious ability for stealth. The leopard consumes virtually any animal that it can hunt down and catch. Its habitat ranges from rainforest to desert terrains.

It is listed as Near Threatened on the IUCN Red List because it is declining in large parts of its range due to habitat loss and fragmentation, and hunting for trade and pest control. It is regionally extinct in Hong Kong, Singapore, Kuwait, Syria, Libya and Tunisia.

Leopards show a great diversity in coat color and rosettes patterns. In general, the coat color varies from pale yellow to deep gold or tawny, and is patterned with black rosettes. The head, lower limbs and belly are spotted with solid black. Coat color and patterning are broadly associated with habitat type. Their rosettes are circular in East Africa but tend to be squarer in southern Africa and larger in Asian populations. Their yellow coat tends to be more pale and cream colored in desert populations, more gray in colder climates, and of a darker golden hue in rainforest habitats. Overall, the fur under the belly tends to be lighter coloured and of a softer, downy type. Solid black spots in place of open rosettes are generally seen along the face, limbs and underbelly.

Leopards are agile and stealthy predators. Although they are smaller than most other members of the Panthera genus, they are able to take large prey due to their massive skulls that facilitate powerful jaw muscles. Head and body length is usually between 90 and 165 cm (35 and 65 in). The tail reaches 60 to 110 cm (24 to 43 in) long, around the same length as the tiger’s tail and proportionately long for the genus (though snow leopards and the much smaller marbled cats have relatively longer tails). Shoulder height is from 45 to 80 cm (18 to 31 in). The muscles attached to the scapula are exceptionally strong, which enhance their ability to climb trees. They are very diverse in size. Males are about 30% larger than females, weighing 30 to 91 kg (66 to 201 lb) compared to 23 to 60 kg (51 to 132 lb) for females. Large males of up to 91 kg (201 lb) have been documented in Kruger National Park in South Africa; however, males in South Africa’s coastal mountains average 31 kg (68 lb) and the females from the desert-edge in Somalia average 23 to 27 kg (51 to 60 lb). This wide variation in size is thought to result from the quality and availability of prey found in each habitat. The most diminutive leopard subspecies overall is the Arabian leopard (P. p. nimr), from deserts of the Middle East, with adult females of this race weighing as little as 17 kg (37 lb).

Other large subspecies, in which males weigh up to 91 kg (201 lb), are the Sri Lankan leopard (P. p. kotiya) and the Anatolian leopard (P. p. tulliana). Such larger leopards tend to be found in areas which lack tigers and lions, thus putting the leopard at the top of the food chain with no competitive restriction from large prey items. The largest verified leopards weighed 96.5 kg (213 lb) and can reach 190 cm (75 in) in head-and-body length. Larger sizes have been reported but are generally considered unreliable.  The leopard’s body is comparatively long, and its legs are short.

Leopards may sometimes be confused with two other large spotted cats, the cheetah, with which it may co-exist in Africa, and the jaguar, a neotropical species that it does not naturally co-exist with. However, the patterns of spots in each are different: the cheetah has simple black spots, evenly spread; the jaguar has small spots inside the polygonal rosettes; while the leopard normally has rounder, smaller rosettes than those of the jaguar. The cheetah has longer legs and a thinner build that makes it look more streamlined and taller but less powerfully built than the leopard. The jaguar is more similar in build to the leopard but is generally larger in size and has a more muscular, bulky appearance.

Leopards have the largest distribution of any wild cat, occurring widely in Africa as well as eastern and southern Asia, although populations have shown a declining trend and are fragmented outside of sub-Saharan Africa. Within sub-Saharan Africa, the species is still numerous and even thriving in marginal habitats where other large cats have disappeared. Populations in North Africa may be extinct. Data on their distribution in Asia are not consistent. Populations in southwest and central Asia are small and fragmented; in the northeast, they are critically endangered. In the Indian subcontinent, Southeast Asia, and China, leopards are still relatively abundant. Of the species as a whole, its numbers are greater than those of other Panthera species, all of which face more acute conservation concerns.

Leopards are exceptionally adaptable, although associated primarily with savanna and rainforest. Populations thrive anywhere in the species range where grasslands, woodlands, and riverine forests remain largely undisturbed. In the Russian Far East, they inhabit temperate forests where winter temperatures reach a low of −25 °C (−13 °F). They are equally adept surviving in some of the world’s most humid rainforests and even semi-arid desert edges.

Leopards in west and central Asia try to avoid deserts, areas with long-duration snow cover and areas that are near urban development. In India, leopard populations sometimes live quite close to human settlements and even in semi-developed areas. Although occasionally adaptable to human disturbances, leopards require healthy prey populations and appropriate vegetative cover for hunting for prolonged survival and thus rarely linger in heavily developed areas. Due to the leopard’s superlative stealthiness, people often remain unaware that big cats live in nearby areas.

Fossil records

Fossils of early leopard ancestors have been found in East Africa and South Asia from the Pleistocene of 2 to 3.5 Ma. The modern leopard is suggested to have evolved in Africa 470,000–825,000 years ago and radiated across Asia 170,000–300,000 years ago.

In Europe, the leopard is known at least since the Pleistocene. Fossil leopard bones and teeth dating from the Pliocene were found in Perrier in France, northeast of London, and in Valdarno in Italy. At 40 sites in Europe fossil bones and dental remains of leopards dating from the Pleistocene were excavated mostly in loess and caves. The sites of these fossil records range from near Lisbon, near Gibraltar, and Santander Province in northern Spain to several sites in France, Switzerland, Italy, Austria, Germany, in the north up to Derby in England, in the east to Přerov in the Czech Republic and the Baranya in southern Hungary. The Pleistocene leopards of Europe can be divided into four subsequent subspecies. The first European leopard subspecies P. p. begoueni is known since the beginning of the early Pleistocene and was replaced about 600,000 years ago by P. p. sickenbergi, which in turn was replaced by P. p. antiqua at around 300,000 years ago. The last form, the Late Pleistocene Ice Age leopard (P. p. spelaea) appeared at the beginning of the Late Pleistocene and survived until about 24,000 years ago in large parts of Europe.

Taxonomy and evolution

Like all of the feline family, the Panthera genus has been subject to much alteration and debate, and the exact relations between the four species as well as the clouded leopard and snow leopard have not been effectively resolved.

The leopard was among the first animals named under the modern system of biological classification, since it was described by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae. Linnaeus placed the leopard under the genus Felis as the binominal Felis pardus. In the 18th and 19th centuries, most naturalists and taxonomists followed his example. In 1816, Lorenz Oken proposed a definition of the genus Panthera, with a subgenus Panthera using Linnaeus’ Felis pardus as a type species. But most disagreed with his definition, and until the beginning of the 20th century continued using Felis or Leopardus when describing leopard subspecies. In 1916, Reginald Innes Pocock accorded Panthera generic rank defining Panthera pardus as species.

It is believed that the basal divergence amongst the Felidae family occurred about 11 million years ago. The last common ancestor of the lion, tiger, leopard, jaguar, snow leopard, and clouded leopard is believed to have occurred about 6.37 million years ago. Panthera is believed to have emerged in Asia, with ancestors of the leopard and other cats subsequently migrating into Africa. The researchers suggest that the snow leopard is most closely aligned with the tiger, whereas the leopard possibly has diverged from the Panthera lineage subsequent to these two species, but before the lion and jaguar.

Results of phylogenetic analyses of chemical secretions amongst cats has suggested that the leopard is closely related to the lion. Results of a mitochondrial DNA study carried out later suggest that the leopard is closely related to the snow leopard, which is placed as a fifth Panthera species, Panthera uncia.
