The chytrid fungus has been found on at least 287 species of frogs in 37 countries around the world and is suspected to be a major cause of amphibian die-offs. Among its victims is the Rabb’s fringe-limbed treefrog, which inhabited the tropical forest canopy of central Panama. With its big webbed feet, the frog could glide, limbs outstretched, from high branches safely to the ground. The species wasn’t discovered until late 2005, when a team of scientists visited the region to collect frogs and save them in captivity before the chytrid fungus arrived. Chytrid was detected in the area the following year, and the last known wild individual, a male, was heard calling in December 2007. Researchers at Zoo Atlanta and the Atlanta Botanic Garden attempted to breed the frogs but were unsuccessful. As of April 2011, there was only one lone male surviving at the botanic garden. – SZ

Hunting actually was a minor contributor to the Red Wolf demise. Habitat loss was a major contributor, but the finishing blow was the expansion eastward of the Coyote. They crossbred with the Red Wolf and just about wiped them out.
There was a viable population of the wolf in southern AR until the late 1940s. That's when coyotes began to show up. By the mid to late 1950s the wolf had disappeared.

thank you, thank you, thank you from my heart for saving the habitat as well as these beautiful wolves. i feel a strong connection to all wolves and this story was uplifting, encouraging, and worth my two minute feeble effort to say thank you for caring about and taking action to save these animals.

Our eyes are in the front of our heads but we are blind to the future of the earth and its inhabitants. We are the last species to evolve from earth's origins (not inclduing nuclear mutations) and we seem to be intent on being its last to survive our own predatory habits. Wait. Isn't that why we have wars, to eliminate ourselves?

A porpoise endemic to Mexico, the vaquita (Phocoena sinus) is now widely-recognized by marine mammal biologists as the most-endangered marine mammal in the world (Jaramillo-Legorreta et al. 2007). The species is listed as Critically Endangered by the IUCN Red List authority, and as Endangered on the U.S. Endangered Species List, and Mexico has also listed the vaquita as Endangered and considered it the first of five top-priority species for conservation action (SEMARNAT 2008).
Population size of the vaquita was estimated in 2008 from a line-transect survey. The resulting estimate was 245 individuals (Gerrodette et al. 2011). This is much lower than a 1997 estimate using similar methods (567 individuals - Jaramillo-Legorreta et al. 1999). From this, it was estimated that the population has been declining by 7.6% per year, and if the decline has continued in the last couple of years, then there would likely be only about 200 porpoises left now. All this means there is a window of at most a few years in which to implement solutions to save the species (see Jaramillo-Legorreta et al. 2007).
