Second, order selection.--At the MCP home range level, habitat selected by badgers was significantly different from available habitat ([lambda] = 0.249, P = 0.004).
To estimate home range size, we used a minimum convex polygon (Hayne 1949) and fixed Kernel density estimation (Worton 1989) with an adjusted smoothing factor (fixed multiplier of [h.sub.ref] = 0.43), which was calculated as proposed by Wauters et al.
As McCoy says, "Age apparently did not play a role in determining the size of a buck's home range, and from previous research studies, buck movements are largely driven by their own personalities.
The proportion of optimal habitat in home range overlap was 1.8X higher in Jackman than in Aroostook (P < 0.00); the proportion in Berlin was similar to that at both Maine sites.
Scaly-sided Merganser, Daily travel distance, Mergus squamatus, Daily home range, Group characteristics.
In addition, the annual home range in the first year was calculated for each bear using two methods.
We used the six cover types (Table 2) to conduct weighted compositional analyses of habitat selection at the study area scale and home range scale (Johnson 1980).
For each individual, the resulting home ranges from both data sets were compared in terms of the total calculated area and their spatial coincidence, which was assessed as the percentage of Home Range intersection (HR estimate), Volume Intersection statistic (VI) and Bhattacharyya's affinity estimate (BA) (Fieberg & Kochanny 2005, Kochanny et al., 2009).
There is only one study that investigated the home range of jaguarundis in South America (Michalski et al., 2006), and few references about densities of Southern tiger cat populations through its distribution in Brazil (Tortato and Oliveira, 2005; Oliveira-Santos et al., 2012).
For each season, we estimated 50% fixed-kernel seasonal core areas and 85% fixed-kernel seasonal ranges (Worton, 1989) using ArcGIS 9.3.1 Home Range Tool adapted from ArcView 3.3 Home Range Extension (Rogers and Carr, 1998) with a least-squares cross-validation smoothing parameter (Worton, 1995; Seaman and Powell, 1996; Seaman et al., 1999).
Often a square mile is used as a baseline for a buck's home range in good habitat, though there are clearly many places in which that figure is way off.
"Numerous studies have shown that a buck's home range size is highly variable and not strongly correlated to age, daily movements or any number of factors,", said Ross.
