Habitats have substantial influence on the distribution and abundance of animals. Animals'
selective movement yields their habitat use. Animals generally are more abundant in …

The main goal of non‐invasive genetic capture‐mark‐recapture (CMR) analysis is to gain an
unbiased and reliable population size estimate of species that cannot be sampled directly …

The status of many carnivore populations is of growing concern to scientists and
conservationists, making the need for data pertaining to carnivore distribution, abundance …

An increasing number of studies employ spatial capture-recapture models to estimate
population size, but there has been limited research on how different spatial sampling …

ABSTRACT DNA‐based mark‐recapture has become a methodological cornerstone of
research focused on bear species. The objective of such studies is often to estimate …

We present the first rigorous estimate of grizzly bear (Ursus arctos) population density and
distribution in and around Glacier National Park (GNP), Montana, USA. We used genetic …

Selecting a survey design to detect change through time in an ecological resource requires
balancing the speed with which a given level of change can be detected against the cost of …

A fundamental challenge to estimating population size with mark–recapture methods is
heterogeneous capture probabilities and subsequent bias of population estimates …

Non‐invasive genetic sampling (NGS) of hair and faeces has become an important tool for
monitoring wildlife populations, but many managers question the feasibility and cost …

We evaluated the potential of two noninvasive genetic sampling methods, hair traps and
bear rub surveys, to estimate population abundance and trend of grizzly (Ursus arctos) and …
