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.
An illustration of the three idealized types of curve (logarithmic scale) 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).
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 ...

The wolverine is the largest land-dwelling species in the mammal family called Mustelidae, making it a close cousin of weasels, ferrets, skunks and badgers.
Thus, any calculation of a minimum viable population (MVP) will depend on the population projection model used. [3] A set of random (stochastic) projections might be used to estimate the initial population size needed (based on the assumptions in the model) for there to be, (for example) a 95% or 99% probability of survival 1,000 years into the ...
The half-life of a population is the time taken for the population to decline to half its size. We can calculate the half-life of a geometric population using the equation: N t = λ t N 0 by exploiting our knowledge of the fact that the population (N) is half its size (0.5N) after a half-life. [20]
