Home range size.--Home range size is a central, but highly complex, metric used to understand a species' ecology (Powell, 2000) and serves as a fundamental first step towards elucidating basic habitat requirements.
Habitat selection was evaluated by comparing the utilized and available habitats at two spatial levels: second-order selection (home range composition vs.
McCoy found the average fall home range for his 37 bucks was only 350 acres.
Although home range composition can be reasonably defined, there is no estimate for the amount of time moose spend in each habitat type.
When calculated using the MCP method, Bear A's first-year home range area was 5.4 times the size of the mean home range of the other four females, while her second-year home range area was only 0.11 the size of the others' mean home range (Table 1).
To evaluate whether home range and core area were exclusively used, we estimated the home range and core area overlap of pairs of neighboring weasels tracked during the same month, including overlap between adults of the same sex, adults and juveniles, juveniles and juveniles, and females and males using the utilization distribution overlap index (UDOI, Fieberg et al.
Except for the consecutiveness dependent method of Brownian Bridges, where the pattern is the opposite, the males SoB based home range estimations were consistently larger (95% contour: 9.9% to 42.8%; 50% contour: 2.7% to 22.7%), than those resulting from the IT data.
The aim of this study is to estimate the home range size and the minimal densities for three small felid species, namely Southern tiger cat, margay and jaguarondi, in a fragmented area of southern Atlantic Forest, one of the most endangered biomes in the world.
We determined that home range estimates stabilized after 21 locations were used (Seaman et al., 1999), and we subsequently calculated home ranges only for squirrels with [greater than or equal to] 21 locations in each season.
Putting a number of acres or square miles on a home range is deceiving, because it almost implies the area is something of a circle or square.
