Estimating population size of fishers (Pekania pennanti ) using camera stations and auxiliary data on home range size

Acceleration Data Reveal Highly Individually Structured Energetic Landscapes in Free-Ranging Fishers (Pekania pennanti)

Investigating animal energy expenditure across space and time may provide more detailed insight into how animals interact with their environment. This insight should improve our understanding of how changes in the environment affect animal energy budgets and is particularly relevant for animals living near or within human altered environments where habitat change can occur rapidly. We modeled f...

Movement ecology of fishers (Pekania pennanti) within a semi-urban landscape

A Geographic Information System Method for Estimating Home Range Size

\Ve developed a new technique to quantify home ranges by using coordinate-based data that were collected at srnall time intenals and entered into a Geographic Information System (GIS). We used this technique (digitized polygons [DP]) and 4 other established methods to estimate home range sizes of groups of black howler monkeys (Alorrana pigra). \Ve calculated the size of the area used by the st...

Estimating home-range size: when to include a third dimension?

Most studies dealing with home ranges consider the study areas as if they were totally flat, working only in two dimensions, when in reality they are irregular surfaces displayed in three dimensions. By disregarding the third dimension (i.e., topography), the size of home ranges underestimates the surface actually occupied by the animal, potentially leading to misinterpretations of the animals'...
