Federal scientists in 2018 projected a massive decline in spring snow due to climate change and found that predicted losses in the wolverine population will be much greater in the coming decades.
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 ...
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 ...

Recently, genetic analyses of surviving megafaunal populations have contributed new evidence, leading to the conclusion: "The inability of climate to predict the observed population decline of megafauna, especially during the past 75,000 years, implies that human impact became the main driver of megafauna dynamics around this date."
(Reuters) -The North American wolverine, a fierce mountain predator closely related to badgers and skunks, gained U.S. protection as a threatened species on Wednesday under a Biden administration ...
In population genetics and population ecology, population size (usually denoted N) is a countable quantity representing the number of individual organisms in a population. Population size is directly associated with amount of genetic drift , and is the underlying cause of effects like population bottlenecks and the founder effect . [ 1 ]
