But fragmented landscapes, of which we see only the physical connectivity, may remain functionally connected from the perception of animals capable of crossing gaps. Most studies of animal movements across fragmented landscapes have used insects, and extrapolation of results to other taxa may not be valid. I am investigating the degree to which a forest carnivore, the marten, uses landscapes fragmented by commercial cleat-cut logging. By revealing threshold values of landscape fragmentation beyond which habitat is no longer useful to animals, my research will facilitate landscape planning toward minimum effect on target species, and contribute to sustainable timber harvest practices. Tracey studies spatial dynamics of cariboo herds in northern Ontario, and is co-supervised with Dr. Frank Mallory at Laurentian University, Sudbury, Ontario.
Social dominance is defined as priority of access to resources.
However, the actual relationship between dominance behaviours and resource density within individual territories has rarely been examined in a mammal. Using behavioural experiments in the field, I will examine relationships between dominance behaviours, scent marks, body size, and residency status. Territories will be determined through radiotelemetry. I will be conducting these studies in both young regenerating forests, and older uncut forests. American marten show preferences for mature coniferous forest.
