The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. Many factors are taken into account when assessing the conservation status of a species: not simply the number remaining, but the overall increase or decrease in the population over time, breeding success rates, known threats, and so on. The best-known worldwide conservation status listing and ranking system is the IUCN Red List, but other more specialised lists and systems exist, such as Th ...

The platypus occupies much the same general distribution as it did prior to European occupation of Australia, except for its loss from the state of South Australia. However, local changes and fragmentation of distribution due to human modification of its habitat are documented. The species currently inhabits eastern Australia from around Cooktown in the north to Tasmania in the south. Although not found in the west-flowing rivers of northern Queensland, it inhabits the upper reaches of rivers flowing to the west and north of the dividing ran ...

Cheetah cubs have a high mortality rate due to genetic factors and predation by carnivores in competition with the cheetah, such as the lion and hyena. Some biologists now believe that they are too inbred to flourish as a species. Cheetahs are included on the IUCN list: vulnerable species (African subspecies threatened, Asiatic subspecies in critical situation) as well as on the US ESA: threatened species - Appendix I of CITES (Convention on International Trade in Endangered Species). Approximately 12,400 cheetahs remain in the wild i ...

According to the RAHA criteria, there is not enough data to decide if the coconut crab is an endangered species, and therefore it is listed as DD (data deficient). However, according to some reports the populations are quite large, with one of the largest populations being on Caroline Island. It is believed that the coconut crab is quite common on some islands, but rather rare on others. Coastal development on m ...

A decline in Island Fox populations was identified in the 1990s. On San Miguel Island the decline began in 1994, the adult population falling from 450 to 15 in 1999. Similar population declines were discovered on Santa Cruz Island, where the population decreased from 2,000 adults in 1994 to less than 135 in 2000, and on Santa Rosa Island where 1,500 foxes recorded in 1994 were reduced to 14 animals by 2000.[11] Golden Eagle predation, discovered when foxes were radio-collared and monitored, p ...

For some time, Tasmania was the last refuge of large marsupial carnivores. All of the larger carnivorous marsupials became extinct in mainland Australia shortly after humans arrived. Only the smallest and most adaptable survived. Fossil evidence from western Victoria shows that Tasmanian Devils retained a place on the Australian mainland until around 600 years ago (about 400 years before European colonisation).[4] Their extinction is attributed to predation by dingoes and hunting ...

Heavy logging activity and hunting by collectors decimated the population of Ivory-billed Woodpeckers in the late 1800s. It was given up for extinct in the 1920s, when a pair turned up in Florida, only to be shot for specimens. By 1938, only 20 or so individuals remained in the wild, located in the old-growth forest called the Singer Tract in Louisiana, where logging rights were held by the Chicago Mill and Lumber Company, which brushed aside pleas from four Southern governors and the National Audubon Society that the tract be publicly purch ...

It is unclear how much a consummate increase in fishing for Great Whites had to do with the decline of Great White population from the 1970s to the present. No accurate numbers on population are available, but populations have clearly declined to a point at which the Great White is now considered endangered. Their reproduction is slow, with sexual maturity occurring at about nine years of age, such that population can take a long time to rise. The Convention on International Trade in Endangered Species (Cites) has put the Great White ...

The Short-beaked Echidna is common throughout most of temperate Australia and lowland New Guinea, and is not listed as endangered. In Australia, the number of Short-beaked Echidnas has been less affected by land clearing than have some other species, since Short-beaked Echidnas do not require a specialised habitat beyond a good supply of ants and termites. Despite their spines, they are preyed on by birds, Tasmanian Devils, cats, foxes and dogs. They were eaten by Indigenous Australians and the early European settlers of Australia. The most ...

The coconut crab (Birgus latro) is the largest terrestrial arthropod in the world. It is a derived hermit crab which is known for its ability to crack coconuts with its strong pincers in order to eat the contents. It is sometimes called the robber crab or palm thief (in German, Palmendieb), because some coconut crabs steal shiny items such as pots and silverware from houses and tents. Another name is the terrestrial hermit crab, due to the use of shells by the young animals (although terrestrial hermit c ...

Whaling is the hunting and killing of whales. Historically, poor conservation management by many nations led to far more whales being killed than could be sustained and to near extinction of several species. Whales are killed by firing a harpoon near the head of the animal. An explosive charge inside the harpoon then explodes beneath the whale's skin, killing it. International cooperation on whaling regulation started in 1931 and a number of bi- and multi-lateral agreements now exist in this area, the International Convention f ...

The Cheetah (Acinonyx jubatus) is an atypical member of the cat family (Felidae) that hunts by speed rather than by stealth or pack tactics. It is the fastest of all terrestrial animals and can reach speeds of up to 100 km/h (62 mph) in short bursts. Cheetah - Description. The cheetah's body is svelte and muscular, though it seems slender and almost fragile in build. Its chest is deep and its waist narrow. It has a small head and short muzzle, high-placed eyes, large nostrils for large oxygen intake, ...

As is often the case with uncharacteristically large species, the giant clam has been historically misunderstood. Even reputable scientific and technical manuals once claimed that the great mollusk had caused deaths. In those days the Giant clam was also known as killer clam or man-eating clam. Versions of the U.S. Navy Diving Manual even gave detailed instructions for releasing oneself from its grasp by severing the add ...

Three species of hippos became extinct within the Holocene on Madagascar, one of them as recently as about a thousand years ago. A dwarf species, Phanourios minutis, existed on the island of Cyprus but became extinct at the end of the Pleistocene. Whether this was caused by human intervention is debated (see Aetokremnos). In 2005, the population of hippos in Democratic Republic of the Congo's Virunga National Park had dropped to 800 to 900 individuals from around 29,000 in the mid 1970s, raising concerns about the viability of ...

One of the earliest illustrations of a mantid appears in the ancient Chinese text Erh Ya, where its attributes in poetry (representing courage and fearlessness) are given, as well as a brief description. A later text, Pen ts'ao from 1108, is impressively correct on the construction of the egg packages, the development cycle, the anatomy and even the function of the antennae. By the 18th century the biology and morphology of the mantids became relatively accurate. Roesel von Rosenhof accurately illustrated and described them in the Insekten-Belust ...
