Adaptive habitat selection by a single celled alga?
(2014-01-22)Faculty and students in the Department of Biology are bound together by a common interest in explaining the diversity of life, the fit between form and function, and the distribution and abundance of organisms. The research ... -
Behavioural analysis of meadow jumping mice; Zapus Hudsonius
(2020)Temperament studies of animals can provide unique insight on how behaviour, genetics and environmental factors interact to influence the evolution and dynamics of populations. This, in turn, can be used to predict how ... -
Critical decisions: risk allocation in a model arthropod (Folsomia candida)
(2015-06-15)Risk allocation theory predicts that foraging animals moderate predation risk by allocating their foraging effort and space use according to their energetic demands. Undernourished animals have a greater need for energy ... -
Density-dependent habitat selection alters fitness in a clonal hexapod
(2019)Density-dependent habitat selection shapes the distribution and abundance of organisms and thus informs our understanding of the eco-evolutionary process. When habitat choice is contingent on an individual’s expectation ... -
Habitat change and the scale of predation risk
(2004)In their efforts to maximise fitness while reducing the probability of dying, animals must trade off food for safety. The trade-off is likely to depend on habitat and habitat change. I imagine an environment with both safe ... -
How does environmental variation effect fitness of density-dependent habitat selectors? / by Jody T. MacEachern.
(2010)The spatial distribution of animals can arise through a variety of habitat-selection strategies. It is unclear which habitat characteristics lead to the evolution of one of these strategies over another. Thus I use an ... -
Is patch use determined by fine-scale microhabitat differences or density dependent habitat selection?
(2006)If individuals base their patch and habitat choices on fine-scale differences in microhabitat, then their use o f patches, defined by capture sites, should correspond with measures o f microhabitat. But if individuals ... -
Life on the edge : the role of habitat selection on vole density near forest boundaries
(1997)Theories of density-dependent habitat selection predict pronounced gradients of population density near habitat edges. Population density in high-quality habitats should decline toward edges with lower-quality habitats, ... -
Predator mediated indirect effects of livestock on native prey
(2012-11-10)Livestock are common in many protected areas and due to their negative effects pose a considerable challenge to protected area managers attempting to conserve native ecosystems. Negative effects include resource competition ... -
Safety from predators or competitors? Interference competition leads to apparent predation risk
(2013-02-01)Prey often react to predation risk by foraging preferentially in safe, rather than risky, patches. Yet prey also must deal with the negative effects of competition for the same patches. The pattern of patch use can mimic ... -
Spatial scaling in northern landscapes : habitat selection by small mammals
(1994)I examined a series of simple and repeated northern landscapes in the Hudson Bay Lowland of Ontario to document regional and local patterns of population abundance of red-backed voles {Clethrionomys gapperi). I tested ...
