Endangered species in the context of "Morus rubra"

The genus Pan consists of two extant species: the bonobo and the chimpanzee. Taxonomically, these two ape species are collectively termed panins; however, both species are more commonly referred to collectively using the generalized term chimpanzees, or chimps. Together with humans, gorillas, and orangutans, they are part of the family Hominidae (the great apes, or hominids). Native to sub-Saharan Africa, chimpanzees and bonobos are currently both found in the Congo jungle, while only the chimpanzee is also found further north in West Africa. Both species are listed as endangered on the IUCN Red List of Threatened Species, and in 2017 the Convention on Migratory Species selected the chimpanzee for special protection.

Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide.

Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species.

Fish stocking is the practice of releasing fish that are artificially raised in a hatchery into a natural body of water (river, lake, or ocean), to supplement existing wild populations or to create a new population where previously none exists. Stocking may be done for the benefit of commercial, recreational or tribal heritage fishing, but may also be done for ecological conservation to restore or increase the population of threatened/endangered fish species that is pressured by prior overfishing, habitat destruction, and/or competition from invasive species.

Fish stocking may be conducted by governmental fisheries management agencies, non-profit organizations, and voluntary associations in public waters, or by for-profit NGOs, clubs and commercial enterprises in privately owned waters. When in public waters, fish stocking creates a common-pool resource which is rivalrous in nature but non-excludable. Thus, on public grounds, all can enjoy the benefits of fishing so long as fish continue to be stocked.

Shebenik National Park (Albanian: Parku Kombëtar i Shebenikut) is a national park in eastern Albania adjacent to the border with North Macedonia. It encompasses 34,507.9 hectares (345.079 km) and is specifically marked by a mountainous landscape supplied with glacial lakes, valleys, dense coniferous and deciduous forests and alpine meadows and pastures. Elevations in the park vary from 300 metres to over 2,200 metres above the Adriatic at the peak of Shebenik and Jabllanica, hence the name. It dwells a number of endangered species that are fast becoming rare in Southern Europe, including the brown bear, gray wolf and Balkan lynx. The abundance in wildlife can in part be explained by the variety of vegetation types and remote location.

The park offers some of the most rugged scenery in the eastern section of country that were carved into their present shapes by the glaciers of the last ice age. It is home to 14 glacial lakes, the highest situated between 1,500 and 1,900 metres elevation above the Adriatic. Small cirque glaciers are fairly common in the mountain ranges, situated in depressions on the side of many mountains. Two rivers flow and multiple smaller water sources flow through the park's area including the rivers of Qarrishte and Bushtrice, both of which are 22 km long. The park area is thought to contain one of the primary remaining ranges of the Balkan lynx, a subspecies of the Eurasian lynx.

The wild horse (Equus ferus) is a species of the genus Equus, which includes as subspecies the modern domesticated horse (Equus ferus caballus) as well as the endangered Przewalski's horse (Equus ferus przewalskii, sometimes treated as a separate species i.e. Equus przewalskii). The European wild horse, also known as the tarpan, that went extinct in the late 19th or early 20th century has previously been treated as the nominate subspecies of wild horse, Equus ferus ferus, but more recent studies have cast doubt on whether tarpans were truly wild or if they actually were feral horses or hybrids.

Other subspecies of Equus ferus may have existed and could have been the stock from which domesticated horses are descended. Przewalski's horse had reached the brink of extinction, but was reintroduced successfully into the wild. The tarpan became extinct in the 19th century, but is theorized to have been present on the steppes of Eurasia at the time of domestication. Since the extinction of the tarpan, attempts have been made to reconstruct its phenotype using domestic horses, resulting in horse breeds such as the Heck horse. However, the genetic makeup and foundation bloodstock of those breeds is substantially derived from domesticated horses, so these breeds possess domesticated traits.

Nikolay Mikhaylovich Przhevalsky (or Przewalski or Prjevalsky; 12 April [O.S. 31 March] 1839 – 1 November [O.S. 20 October] 1888) was a Russian geographer and a renowned explorer of Central and East Asia. Although he never reached his ultimate goal, the city of Lhasa in Tibet, he still travelled through regions then unknown to Westerners, such as northern Tibet (modern Tibet Autonomous Region), Amdo (now Qinghai) and Dzungaria (now northern Xinjiang). He contributed substantially to European knowledge of Central Asian geography.

Przhevalsky described several species previously unknown to European science, such as Przewalski's horse, Przewalski's gazelle, and the wild Bactrian camel, all of which are now endangered. He was also a mentor of the explorer Pyotr Kozlov.

African elephants are members of the genus Loxodonta comprising two living elephant species, the African bush elephant (L. africana) and the smaller African forest elephant (L. cyclotis). Both are social herbivores with grey skin. However, they differ in the size and colour of their tusks as well as the shape and size of their ears and skulls.

Both species are at a pertinent risk of extinction according to the IUCN Red List; as of 2021, the bush elephant is considered endangered while the forest elephant is considered critically endangered. They are threatened by habitat loss and fragmentation, along with poaching for the illegal ivory trade in several range countries.

The false gharial (Tomistoma schlegelii), also known by the names Malayan gharial, Sunda gharial and tomistoma, is a freshwater crocodilian of the family Gavialidae native to Peninsular Malaysia, Borneo, Sumatra and Java. It is listed as Endangered on the IUCN Red List, as the global population is estimated at around 2,500 to 10,000 mature individuals.

The species name schlegelii honors Hermann Schlegel.
