Experts say it is the highest density of wolves in the world.
The 1,000-km2 area of the NR within YNP is characterized by lower elevations (1,500 2,200 m), serves as prime wintering habitat for the park's ungulates [25], and supports a higher density of wolves than the Interior (20 99 wolves/1000 km2 versus 2 11 wolves/1000 kminimum; minimum population count for entire YNP ranged between 118 and 172 wolves between 2000 and 2007 [27]).
The Interior of the park (7,991 km2) is higher in elevation (>2,500 m), receives higher annual snowfall, and generally supports lower densities of wolves and ungulates, with the exception of a large migratory herd of bison (Bison bison).
Within these mountains, three areas of relatively high density of Ethiopian wolves can be identified, although wolves are found through the Afroalpine range.
Field and laboratory microcosm experiments have demonstrated that spiderling-spiderling cannibalism can be a significant factor regulating densities of wolf spiders [57], [58].
The prey animals of North American wolves have largely continued to occupy suitable habitats with low human density, and cases of wolves subsisting largely on garbage or livestock are exceptional.
Piecewise non-linear modeling indicated that the optimal density threshold for the SETAR model was 3.4, which on a raw scale is a density of approximately 30 wolves (Table 1).
Here, we compare linear and non-linear models describing the contribution of climate to the density fluctuations of the population of wolves on Isle Royale, Michigan from 1959 to 1999.
Here, we present a comparative analysis of linear and non-linear models describing the contribution of climate to the interannual density fluctuations of the population of wolves (Canis lupus) on Isle Royale, Michigan, USA, from 1959 to 1999.
Scientists have hypothesized that returning wolves to the landscape enables aspen to recruit into the forest overstory, via the density-mediated and behaviorally-mediated effects of wolves on their ungulate prey, primarily elk (Cervus elaphus).
House densities were negatively correlated with the likelihood of wolves using a patch for resting or traveling, regardless of their reproductive status (Table 5, Figure 4c).
