Actuallly, because of their isolated habitats, island species are more vulnerable to extinction. Introduced species,such as cats, mongoose, and others have led to the extinction of many birds especially, because of their inability to understand the tactics of the alien predator.
Jaguar, polar bear.
if a species is declining then the species that eats that one has less food and will decline fast as well
All three species of manatee are listed by the World Conservation Union as vulnerable to extinction.
As of now, the polar bear is a vulnerable species, not on the endangered species list, as some populations are increasing.
Of the six species of Sea Lions, 2 species are listed as endangered and one is listed as vulnerable; the other three are not considered to be in any danger of extinction.
Is extinction the word you're looking for ?
The population sizes of a species is directly coordinated with the size of the island. A large island close to shore would have a low extinction rate and a successful immigration rate from animals coming over from the mainland.
The smaller the island the fewer species that can live there. The smaller their populations can be the more vulnerable they are to further disturbance or climate change.
Saving vulnerable species is a role.
they are vulnerable to extinction
"Biological island" is a term given to the last of a species that is on its way to extinction. These species require intense human intervention in order to avoid becoming a genetic dead end, where adaptation and survival cease and the species dies out.
Pandas have been listed as endangered because people have been hunting them and they are close to extinction.
