The North American wolverine has officially been listed as threatened under the Endangered Species Act and will receive long-anticipated federal protections, US officials announced Wednesday, as ...
The world's total wolverine population is not known. The animal exhibits a low population density and requires a very large home range. [ 56 ] The wolverine is listed by the IUCN as Least Concern because of its "wide distribution, remaining large populations, and the unlikelihood that it is in decline at a rate fast enough to trigger even Near ...
"Biologists estimate a loss of more than 40% of suitable wolverine habitat in Idaho by 2060 if we fail to act," said Jeff Abrams, wildlife program associate for the Idaho Conservation League.
Wolverine populations in southwestern Canada plummeted by more than 40% over the past two decades due to overharvesting by trappers, which could have effects across the U.S. border, scientists said.

Some species have been domesticated, e.g. the ferret and some populations of the South American tayra. Mustelidae is one of the oldest families in ...
Research found the wolverine population in a 5,400-square-mile swath of the southern Canadian Rockies declined roughly 40% from 2011 to 2020.
The decline of wild mammal populations globally has been an occurrence spanning over the past 50,000 years, at the same time as the populations of humans and livestock have increased. Nowadays, the total biomass of wild mammals on land is believed to be seven times lower than its prehistoric values, while the biomass of marine mammals had ...
