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.
An animal's
home range is related to its daily travel distance.
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.
Ross also notes that bucks use less of their
home range during breeding time.
