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 ...
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.
A survivorship curve is a graph showing the number or proportion of individuals surviving to each age for a given species or group (e.g. males or females). Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table. There are three generalized types of survivorship curves: [1]
Research found the wolverine population in a 5,400-square-mile swath of the southern Canadian Rockies declined roughly 40% from 2011 to 2020.
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."

Graph of world population over the past 12,000 years . As a general rule, the confidence of estimates on historical world population decreases for the more distant past. Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census.
(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 ...
