The snowshoe hare, also called the varying hare or snowshoe rabbit, is a species of hare found in North America. It has the name "snowshoe" because of the large size of its hind feet. The animal's feet prevent it from sinking into the snow when it hops and walks. Its feet also have fur on the soles to protect it from freezing temperatures.
The Canada lynx, or Canadian lynx, is a medium-sized North American lynx that ranges across Alaska, Canada, and northern areas of the contiguous United States. It is characterized by its long, dense fur, triangular ears with black tufts at the tips, and broad, snowshoe-like paws. Its hindlimbs are longer than the forelimbs, so its back slopes downward to the front. The Canada lynx stands 48–56 cm (19–22 in) tall at the shoulder and weighs between 5 and 17 kg. The lynx is a good swimmer and an agile climber. The Canada lynx was first described by Robert Kerr in 1792. Three subspecies have been proposed, but their validity is doubted; it is mostly considered a monotypic species.
In zoology, mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as "mastology," "theriology," and "therology." The archive of number of mammals on earth is constantly growing, but is currently set at 6,495 different mammal species including recently extinct. There are 5,416 living mammals identified on earth and roughly 1,251 have been newly discovered since 2006. The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management and control. The approximate salary of a mammalogist varies from $20,000 to $60,000 a year, depending on their experience. Mammalogists are typically involved in activities such as conducting research, managing personnel, and writing proposals.
James Hemphill Brown is an American biologist and academic.
Charles Sutherland Elton was an English zoologist and animal ecologist. He is associated with the development of population and community ecology, including studies of invasive organisms.
Crawford Stanley "Buzz" Holling, was a Canadian ecologist, and Emeritus Eminent Scholar and Professor in Ecological Sciences at the University of Florida. Holling was one of the conceptual founders of ecological economics.
The eastern meadow vole, sometimes called the field mouse or meadow mouse, is a North American vole found in eastern Canada and the United States. Its range extends farther south along the Atlantic coast.
A population cycle in zoology is a phenomenon where populations rise and fall over a predictable period of time. There are some species where population numbers have reasonably predictable patterns of change although the full reasons for population cycles is one of the major unsolved ecological problems. There are a number of factors which influence population change such as availability of food, predators, diseases and climate.
Competition is an interaction between organisms or species in which both require a resource that is in limited supply. Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other.
Simon Asher Levin is an American ecologist and the James S. McDonnell Distinguished University Professor in Ecology and Evolutionary Biology and the director of the Center for BioComplexity at Princeton University. He specializes in using mathematical modeling and empirical studies in the understanding of macroscopic patterns of ecosystems and biological diversities.
The Newfoundland pine marten is a genetically distinct subspecies of the American marten found only on the island of Newfoundland in the province of Newfoundland and Labrador, Canada; it is one of only 14 species of land mammals native to the island. The marten was listed as endangered by the COSEWIC in 2001 and has been protected since 1934, however the population still declines. The Newfoundland marten has been geographically and reproductively isolated from the mainland marten population for 7000 years. The Newfoundland pine marten is similar in appearance to its continental cousin, but is slightly larger, with dark brown fur with an orange/yellow patch on the throat. Females are an average weight of 772 grams and males have an average weight of 1275 grams. The Newfoundland subspecies is also observed to inhabit a wider range of forest types than its mainland counterparts. The population characteristics suggest that the Newfoundland marten is a product of unique ecological setting and evolutionary selective factors acting on the isolated island population. The Newfoundland pine marten is omnivorous, feeding on mainly small mammals, along with birds, old carcasses, insects and fruits; it is currently found in suitable pockets of mature forest habitat, on the west coast of Newfoundland and in and around Terra Nova National Park. The Pine Marten Study Area (PMSA) is located in southwestern Newfoundland and is a 2078 km2 wildlife reserve that was created in 1973 to protect the Newfoundland Marten.
The Eminent Ecologist Award is prize awarded annually to a senior ecologist in recognition of an outstanding contribution to the science of ecology. The prize is awarded by the Ecological Society of America. According to the statutes, the recipient may be from any country in the world. However, in practice very few non-U.S. citizens have received the award. The awardee receives lifetime membership in the society.
Edward Smith Deevey Jr., born in Albany, New York, was a prominent American ecologist and paleolimnologist, and an early protégé of G. Evelyn Hutchinson at Yale University. He was a creative pioneer in several areas, including quantitative palynology, cycling of natural isotopes, biogeochemistry, population dynamics, systematics and ecology of freshwater zooplankton, and he promoted the use of life tables in ecology.
Graeme James Caughley was a New Zealand population ecologist, conservation biologist, and researcher. He combined empirical research with mathematical models, and supported the declining population paradigm.
Richard Shine is an Australian evolutionary biologist and ecologist; he has conducted extensive research on reptiles and amphibians, and proposed a novel mechanism for evolutionary change. He is currently a Professor of Biology at Macquarie University, and an Emeritus Professor at The University of Sydney.
Professor Herbert George Andrewartha, BS (UWA), MAgSc (Melb), DSc (Adel), FAA, was a distinguished Australian research scientist in the fields of entomology, biology, zoology and animal ecology.
Henry Neville "Mick" Southern was an English ornithologist.
Oliver Payne Pearson, or "Paynie" to many that knew him, was an American zoologist and ecologist. Over a very active 50-year career, he served as professor of zoology at UC Berkeley and curator of mammals at the Museum of Vertebrate Zoology. Pearson is best known for his work on the role of predation on vole demography and population cycles, and for his piercing contributions to the biology of South American mammals, but his earlier studies on reproductive and physiological ecology are highly regarded as well.
Judith (Judy) H. Myers is a Canadian-American ecologist. In 2014 she was elected president of the Canadian Society for Ecology and Evolution. Professor Myers is well known for her decades-long research into plant-animal-microbe interactions, including insect pest outbreaks, viral pathogens of insects, and pioneering work on biological control of insects and plants, particularly invasive species. Throughout her career she has advocated strongly for both the public understanding of science and for increasing the number of women in the STEM subjects: Science, Technology, Engineering, and Mathematics.
Anthony Ronald Entrican Sinclair is a professor emeritus of zoology at the University of British Columbia.
