Research Area: Climate change
Recent work has involved herbivores and carnivores movement ecology in Serengeti, woodland caribou, wolves, and moose in northern Ontario, and both wild and Norwegian reindeer. We conduct detailed field and experimental studies of both behavioural and demographic responses to landscape heterogeneity and compare these with theoretical models. As part of the Food from Thought research program, we are also evaluating the impact of anthropogenic stressors (nutrient additions due to fertilizer run-off, pesticide application, and temperature increase due to global climate change) on phytoplankton and zooplankton populations in massive aquatic mesocosms and the effect of marginal land restoration (prairies, wetlands, and secondary forest) on arthropod biodiversity using DNA meta-barcoding.Learn More
Dr. Heyland�s laboratory uses novel functional genomics approaches to study the endocrine and neuroendocrine systems of aquatic invertebrates. Specifically he investigates the function and evolution of hormonal and neurotransmitter signaling systems in the regulation of development and metamorphosis. His research includes Evolutionary development studies of marine invertebrate metamorphosis, eco-toxicogenomic approached to understand endocrine disruption in aquatic ecosystems and water remediation technologies. These projects are integrated with several national and international collaborations ranging form basic scientific work to industry partnerships.Learn More
My research program investigates the ecological and evolutionary processes operating in plant populations, both wild and domesticated. Much of our work is conducted through the lens of plant reproductive systems, which control the quantity and quality of sperm and eggs, patterns of mating, and ultimately the transmission of genetic variation from one generation to the next. Current research projects include: 1) mating system variation and evolution, 2) polyploid speciation, 3) genetic and phenotypic consequences of whole genome duplication; 4) biology of small populations, and 5) impacts of hybridization between introduced species and endangered congeners. We work on a variety of study systems, including Arabidopsis, apple, strawberry, fireweed, American chestnut, and mulberry.Learn More
In eastern Canada, the lumpfish and a North American wrasse, the cunner, significantly reduce adult lice densities on salmon living in marine sea cages. My group's work has the following objectives: 1) determine the best size-class of cunners to use in commercial sea cages; 2) examine variation in lice-cleaning performance among cunners and among lumpfish from different stocks; 3) assess heritable variation in lice eating behaviour; 4) Conduct lice challenges of pedigreed salmon with and without the lice cleaner fish present.
3) Increased sea surface temperatures have allowed larval shore crab to invade western Canadian shores and prey on indigenous snail species. We are identifying genomic changes correlated with adaptation to predators in a 25 year field experiment near Bamfield, BC.
