We address questions about how biodiversity arises in single populations of fishes composed of alternate ecotypes that live in different lake habitats. We study the factors that regulate the formation of specialized ecotypes and have expanded theory by evaluating the role of phenotypic plasticity in adaptive divergence. Experience with fish resource polymorphism since 1993 uniquely positions us to investigate how different ecotypes evolve and may be converted into new species. We also study the effects of commercial fishing on natural populations. This work is important because diversity within populations is rarely considered in the contexts of ecological function, management and conservation, or its capacity to buffer populations from adverse effects of environmental change.

Dr. Heyland´┐Żs 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.

My research focuses on the reproductive physiology of fish. We study which hormones affect ovarian follicle development and if there are hallmark responses (changes in hormone biosynthesis, receptor abundance, recruitment of downstream activators) that determine whether an ovarian follicle is destined to mature and ovulate. This research is fundamental to defining spawning success which is a prime measure of reproductive fitness and provides the toolbox that we use to examine the mechanisms by which endocrine disrupting compounds (pharmaceuticals; ammonia) and complex environmental effluents (municipal waste water, pulp mills; oils sands process affected water) affect ovarian physiology.

In the next 5 years, I will shift my research strategy by consolidating 4 streams of my past research: temporal dynamics, host-symbiont interactions, small mammal metacommunity dynamics, and DNA-based species identification and bioinformatics. I will focus on a study system that combines my past strengths in metacommunity ecology at multiple scales, but will apply them to a novel system: microbial metacommunities nested within a matrix of metacommunity of different host species.
