Endangered Species

Giant panda (Ailuropoda melanoleuca) – everyone loves a panda…they might be the kitschiest animal humanity has driven to the brink of extinction yet. Their range is fragmented and they are still subject to disease, occasional predation, and starvation when large swathes of the bamboo on which they feed completes its life cycle and dies.

 

Tiger (Panthera tigris) – slash-and-burn agriculture, along with logging, and human encroachment, have hugely diminished the habitat available to these felines, which require extensive ranges capable of supporting the large herbivores that constitute the bulk of their diets.

 

Whooping crane (Grus americana) – hunting and reduction of their wetland habitat had vitiated the population and concerted efforts to salvage remnant birds did not being until the late 1960s. Today, there are over 400 birds, thanks in large part to innovative breeding programs.

 

Blue whale (Balaenoptera musculus) – commercial hunting of the species was ultimately banned in 1966. It stipulated the maintenance of photo databases of individual specimens and the collection of genetic and migration data in order to better understand the species, which remains at risk from ship collisions and entanglement in fishing nets

.

 

Asian elephant (Elephas maximus) – The burgeoning human population there and elsewhere in Asia creates conflicts for space and resources. And while the tusks of Asian elephants are much smaller than those of their African counterparts, the Asian species is still poached for its ivory, meat, and skin.

 

 

Sea otter (Enhydra lutris) – the luxurious waterproof coat that insulates sea otters from the chilly waters that they inhabit almost led to its extinction. Mammal Protection Act, have helped populations recover to perhaps a third of their earlier numbers, they are highly vulnerable to both natural phenomena such as killer whale predation and to anthropogenic factors such as oil spills.

 

Snow leopard (Panthera uncia) – its natural prey include blue sheep and ibex, but in some areas, it is heavily dependent on domestic animals. The farmers who depend upon the animals shoot the “problem” leopards. Poaching still constitutes a major threat to the species, as does overhunting of its natural prey species.

 

Gorilla (Gorilla beringei andGorilla gorilla) – habitat encroachment and poaching for bushmeat, trophies, and magical talismans have led to substantial losses. Because their social structure is so complex and because they reproduce slowly with females only giving birth once every four years at best the removal of even a few individuals from a gorilla troop can catastrophically impact its ability to sustain itself.

 

Tasmanian devil (Sarcophilus harrisii) – between 1996 and 2008, the population of Tasmanian devils dropped some 60% due a contagious cancer known as Devil Facial Tumour Disease. Captive breeding of uninfected individuals has been instituted and efforts have been made to develop a vaccine for the cancer, which is thought to have stemmed from mutated cells from a single specimen.

 

Orangutan (Pongo pygmaeus) – “Orangutan” is Malaysian for “person of the forest.” Like gorillas and chimpanzees, they have been known to use tools. Unlike other great apes, they are usually solitary or live in groups of fewer than three, making them difficult to track and study.

Bedrohte Tierarten im Wuppertaler Zoo

Ursachen für das Aussterben: Lebensraumzerstörung , Übernutzung (Überfischung), illegaler Handel von wildlebenden Arten, Bejagung, Einbringen gebietsfremder Tiere und Pflanzen, natürliche Feinde, Klimaveränderung und Umweltverschmutzung(Öl, Plastik)

Folgen: Verlust wichtiger und unbezahlbarer Ökosystemfunktionen

  1. Photosyntheseleistung
  2. Klimaregulation
  3. Bestäubung und Verbreitung von Wild-und Nutzpflanzen durch Tiere(Insekte)
  4. Selbstreinigung von Fließgewässern
  5. Verlust bekannter oder potenzieller Heilwirkungen durch Pflanzen
