Michelle L Mclellan currently works at the 'Southwest BC Grizzly Bear Project.'
The objective of this research is to identify areas of population connectivity between the South-Chilcotin, Squamish-Lillooet, Garibaldi-Pitt, and Stein Nahatlatch grizzly bear populations in southwestern British Columbia. These populations of conservation concern are at the southwestern extent of grizzly bear range in North America and have varyin...
Identifying mechanisms of population change is fundamental for conserving small and declining populations and determining effective management strategies. Few studies, however, have measured the demographic components of population change for small populations of mammals (<50 individuals). We estimated vital rates and trends in two adjacent but gen...
Understanding factors that influence daily and annual activity patterns of a species provides insights to challenges facing individuals, particularly when climate shifts, and thus is important in conservation. Using GPS collars with dual-axis motion sensors that recorded the number of switches every 5 minutes we tested the hypotheses: 1. Grizzly be...
Both top-down and bottom-up processes influence herbivore populations, and identifying dominant limiting factors is essential for applying effective conservation actions. Mountain caribou are an endangered ecotype of woodland caribou (Rangifer tarandus caribou) that have been declining, and unsustainable predation has been identified as the proxima...
For wide‐ranging species, it is often too expensive or politically challenging to effectively implement conservation action across their range. In these cases, conservation actions may be vigorously applied where the situation appears most dire, but inadvertently at the expense of where success is more probable. Consequently, it is prudent to use a...
Habitat loss is a leading threat to many species at risk, and as such, the need for habitat restoration is widespread. In the boreal forests of Western Canada, habitat restoration is a key habitat management action needed to achieve self‐sustaining populations of woodland caribou, a federally Threatened species in decline. Hundreds of thousands of...
In marine molluscs, sex change is often labile and is thought to be largely influenced by interactions with conspecifics. Previous studies of calyptraeid gastropods concluded that their social environment influences the timing of protandrous sex change. We conducted field surveys and labo- ratory experiments to examine the effects of conspecifics o...
Grizzly bears in the southern Coast Range of British Columbia occur in a few small, largely isolated populations. This situation is particularly true of the endangered Stein-Nahatlatch (SN) population that has been persisting as a small and isolated group of individuals for many years. This project builds on 5 years of previous telemetry data, habitat use investigations in 2005-2007 and DNA sampling in 2005, 2007 and 2010. The goals of this project are to: 1) document the population trend, 2) improve the estimate of population size, 3) identify the most important limiting factors for the SN and McGillivray mountain (MM) bears (a portion of the South Chilcotin Grizzly Bear Population Unit), and 4) work with agency personnel and local groups to improve on these most critical limiting factors.
