Evolutionary Ecology of Range Limits: Conceptual Syntheses and Empirical Tests
(2014-10-29)
Understanding the environmental, demographic, and evolutionary processes underlying species’ range limits (RLs) is a primary goal of ecology, and increasingly important for conservation in a world of changing species ...
Fish Distributions in Lake Ontario's Eastern Basin and the Upper St. Lawrence River: An Analysis Using GIS and Occupancy Modelling Techniques
Predictive models of species distributions are important tools for fisheries management. Unfortunately, these predictive models can be difficult to perform on large waterbodies where fish are difficult to detect and ...
Diversity and function of the soil microbiome in a North American forest in response to Alliaria petiolata (garlic mustard) invasion.
The disruption of soil microbial communities is thought to be a major contributor to the expansion of invasive plants. Previous research has focused on identifying how invasive plants change soil microbial diversity and ...
Evolutionary Constraints: Phenology and elevational range limits in an annual plant
All species have limits to their geographic distributions and many range limits are stable over centuries, indicating a failure to adapt to conditions beyond the range edge. This simple observation contradicts copious ...
Arboreal Calling Behaviour Across the Range of the Spring Peeper: Potential Consequences and Benefits
Understanding the trade-offs that affect potentially adaptive traits is fundamental to our understanding of evolutionary diversification and speciation. Heterogeneous landscapes may lead to spatial variation in such traits ...
Seasonal activity, depth distribution, and microhabitat associations of resident yellow-phase American eels (Anguilla rostrata) in the upper St. Lawrence River
The American eel (Anguilla rostrata) is an endangered species that inhabits fresh, brackish, and oceanic waters. Eels are elusive; little is known about their seasonal movements, depth distribution, and microhabitat ...
Phenotypic Plasticity Drives Phenological Change in Mandt's Black Guillemot (Cepphus Grylle MandtII)
The ability of individuals to change breeding time is predicted to be an important aspect of adapting to climate change. Changes in breeding time could occur through either behavioural adjustment of breeding time or ...
Stochastic and adaptive processes affect rapid evolution of two invasive plants in North America
Evolution can occur rapidly on timescales of years to decades. In addition to adaptive responses to natural selection, stochastic processes such as gene flow and genetic drift may influence rapid evolution in many species. ...
Assessment of the Effects of Habitat, Harvest and Community Interactions on the Abundance of Walleye Sander Vitreus in Inland Lakes Throughout Ontario
(2012-09-25)
Walleye (Sander vitreus) is an important species to the recreational fishery throughout Ontario. Fish community interactions between walleye and other species are rarely considered when establishing management targets ...
Diatom Assemblages in Relation to Water-Depth Gradients in Eight Boreal Shield Lakes From Northwestern Ontario, Canada
(2010-07-23)
The uncertainty surrounding the impact of future changes in climate and water resources has created renewed interest on how lakes have responded to drought in the past. There is a need to determine potential future available ...
