Genetic structure of a large recolonizing carnivore: the case of the northern cougars (Puma concolor)
DownloadFall 2023
Anthropogenic activities have pressured and altered landscapes resulting in extinctions and extirpations. However, increased conservation efforts and changing management strategies in some large carnivores have resulted in population and range expansion. Population growth and range expansion are...

Fall 2020
Dispersal by flight is a complex life history phase in many insects that is essential to gene flow and range expansion. Many elements contribute to realized dispersal, including biotic and abiotic environmental conditions, as well as intrinsic factors such as morphology, physiology and behavior....

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...

Population structure and associated larval host variation of the forest tent caterpillar, Malacosoma disstria
DownloadFall 2020
The forest tent caterpillar, Malacosoma disstria (M. disstria) Hübner, is a major forest defoliator with regional differences in host association across its range, but the factors shaping its population structure are poorly understood. In eastern Canada, M. disstria primarily feeds on maple (Acer...
