Wildlife includes brown bears, black bears, the endemic Alexander Archipelago wolf, Sitka black-tailed deer, humpback whales, orcas, five species of salmon, bald eagles, harlequin ducks, scoters, and marbled murrelets.

The moose ( North America ) or Eurasian elk ( Europe ) ( Alces alces ) is the largest extant species in the deer family.

Unlike most other deer species, moose are solitary animals and do not form herds.

The Pleistocene epoch was a time of gigantism, in which most species were much larger than their descendants of today, including exceptionally large lions, hippopotamuses, mammoths, and deer.

For example, a change in the physical environment ( geographic isolation by an extrinsic barrier ) would follow number 1, a change in camouflage for number 2 or a shift in mating times ( i. e., one species of deer shifts location and therefore changes its " rut ") for number 3.

Larger specimens usually eat animals about the size of a house cat, but larger food items are known: some large Asian species have been known to take down adult deer, and the African rock python, Python sebae, has been known to eat antelope.

Even grazing species, such as plains bison, pronghorn, and mule deer have shown a proclivity for grazing on the same land used by prairie dogs.

Sri Lanka has declared 24 wildlife reserves, which are home to a wide range of native species such as Asian elephants, leopards, sloth bears, the unique small loris, a variety of deer, the purple-faced langur, the endangered wild boar, porcupines and anteaters.

Examples include the possession of antlers by only male deer, and the brighter coloration of many male birds, in comparison with females of the same species.

All existing populations are at extreme risk from poaching, prey depletion as a result of poaching of primary prey species such as deer and wild pigs, habitat fragmentation and inbreeding.

Some areas of the more southern closed boreal forest also have populations of other deer species such as the elk ( wapiti ) and roe deer.

It shelters mammals such as monkeys and deer ; reptiles ; and over 300 species of birds, as well as approximately 100 varieties of trees.

Prey species include porcupine, squirrel, beaver, marmot, rabbit, vole, mice, shrew, lemming, caribou, roe deer, white-tailed deer, mule deer, sheep, moose, and elk.

Asian Savanna covers and displays Indian rhinoceros and several species of Asian deer and antelope such as axis deer and wapiti.

Species of note in the open enclosures include two subspecies of giraffe, rhinos ( the park has the world's most successful breeding program for Southern white rhinos and is the only New World zoo to have Northern white rhinos ), gaur, vultures, markhor, and many species of antelope, gazelle, and deer.

The fauna in Epirus is especially rich and features species such as bears, wolves, foxes, deer and lynxes.

Male deer of all species ( except the Chinese water deer ) and also female reindeer grow and shed new antlers each year.

For most types of deer in modern English usage, the male is called a " buck " and the female is termed a " doe ", but the terms vary with dialect, and especially according to the size of the species.

The male Red Deer is a " hart ", especially if more than five years old, and the female is a " hind ", especially if three or more years old ; both terms can also be used for any species of deer, and were widely so used in the past.

Terms for young deer vary similarly, with that of most being called a " fawn " and that of the larger species " calf "; young of the smallest kinds may be a kid.

he was working with species of Java, so perhaps some tropical snakes are unusual in this respect.

Of these, 1, 356 ( 33. 6 %) were considered to be threatened and this figure is likely to be an underestimate because it excludes 1, 427 species for which there was insufficient data to assess their status.

Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization.

In 2008, it was discovered that the inactivation of only two genes in one species of annual plant leads to the conversion into a perennial plant.

Although most extant species of Asteraceae are herbaceous, the examination of the basal members in the family suggests that the common ancestor of the family was an arborescent plant, a tree or shrub, perhaps adapted to dry conditions, radiating from South America.

A number of species have come to be considered invasive, including, most notably in North America, dandelion, which was originally introduced by European settlers who used the young leaves as a salad green.

This fossil was originally described as a species of Australopithecus, but White and his colleagues later published a note in the same journal renaming the fossil under a new genus, Ardipithecus.

The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named.

It is improbable, however, that the production of amber was limited to a single species ; and indeed a large number of conifers belonging to different genera are represented in the amber-flora.

He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the " father of biogeography ".

The species was introduced into cultivation at the beginning of the eighteenth century.

No one knows the exact species it was crossed with to produce color variations of white, cream, peach, magenta and nearly red hues.

The program was successful in terms of increasing the population of blue foxes, but their predation of Aleutian Canadian geese conflicted with the goal of preserving that species.

By 1987 a comprehensive survey of the phylum was completed: in all, 4516 species and 339 genera had been named.

When a group of different plant species was prompted by a variety of different stress signals, such as drought or cold, each plant responded uniquely.

Animal species diversity was also significantly impacted: in one study, a Harvard biologist found 24 species of birds and 5 species of mammals in a sprayed forest, while in two adjacent sections of unsprayed forest there were 145 and 170 species of birds and 30 and 55 species of mammals.

According to Ferdinand Bohlmann, the first naturally occurring acetylenic compound, dehydromatricaria ester, was isolated from an Artemisia species in 1826.

The substance so defined was a species.

One of these was the property, an essential universal true of the species, but not in the definition ( in modern terms, some examples would be grammatical language, a property of man, or a spectral pattern characteristic of an element, both of which are defined in other ways ).

A species of Paranthropus, such as Paranthropus robustus, with its crested skull and bipedal gait, was suggested by primatologist John Napier and anthropologist Gordon Strasenburg as a possible candidate for Bigfoot's identity, despite the fact that fossils of Paranthropus are found only in Africa.

The study found that there was ' no verifiable evidence ' of exotic felines loose in Britain, and that the mauled farm animals could have been attacked by common indigenous species.
