Alex Little

Postdoctoral Fellow

Alex’s research integrates all levels of biological organization to explore how environmental stressors interact to threaten animal fitness and ultimately biodiversity. He works from the bottom up, studying how stressor interactions affect the most basic functional levels of physiology in order to make and test predictions about whole-animal physiology and evolutionary theory. His overarching objective is to understand the physiological tradeoffs associated with plasticity so that he can build a framework to model how populations will evolve through the increasingly complex environmental challenges we are creating.

Terra Dressler

PhD Student
Co-Supervised by Tom Dudley (UCSB)

Terra is broadly interested in conservation and restoration of riparian ecosystems, with focus on the genetics, physiology, and ecology of aquatic organisms. She is currently working on using environmental DNA (eDNA) for large-scale mapping of aquatic species biodiversity and using eDNA-generated distribution information to investigate responses of fish populations to environmental stressors.

Emily Hardison

PhD Student

Emily is interested in the physiological mechanisms that drive local adaptation in marine organisms, particularly in species that live across a large geographic range and can be divided into genetically distinct sub-populations. Her research also focuses on understanding how environmental stress alters the physiology and subsequent success of ecologically important marine populations.

Krista Kraskura

PhD Student

Krista is fascinated by phenotypic plasticity and physiological performances of fish. Specifically, she is interested in understanding how fish are being affected by stressful environmental conditions traceable to our activities, and the underlying physiological and biochemical mechanisms behind altered performances. In her research she would love to explore the limits of phenotypic plasticity in allowing fish to remain in a changing/warming world.

Tanya Prystay

MSc Student
Co-Supervised by Steven J. Cooke (Carleton University)

Tanya’s research focuses on using heart rate as a proxy for measuring fish energy investment under various stress conditions. Her current research concentrates on describing the energetic costs of parental care strategies with a focus on smallmouth bass (Micropterus dolomieu) in the Ontario Rideau Lakes (Canada), and sockeye salmon (Onchorhynchus nerka) in British Colombia (Canada). Understanding the magnitude of the cost of spawning can be applied in energetic models, and further our knowledge of the effects of other abiotic and biotic stressors on spawning success.

Clay Steell

MSc Student
Co-Supervised by Steven J. Cooke (Carleton University)

Clay’s research focuses on the feeding physiology and ecology of invasive Lionfish (Pterois volitans/miles) in the Bahamas, based out of the Cape Eleuthera Institute on the island of Eleuthera. He uses a combination of lab-based respirometry and field-based heart rate biologger experiments to explore Lionfish feeding rates and the physiological mechanisms that drive them.
