All first-year Science courses will be delivered virtually for Winter 2021. Due to the COVID-19 provincial lock-down, all students who were expecting in-person labs, should check their McMaster e-mail for important winter announcements..
Research in environmental physiology explores how cells and physiological systems respond to changes in their environment. The environmental physiologists in the Department of Biology study a broad range of topics in a variety of vertebrate (mammals, fish, birds) and invertebrate (insects, crustaceans, worms) animals. Our studies take advantage of a diverse array of cutting-edge techniques, such as in vivo physiological recording, patch-clamp analysis, scanning ion-selective microelectrode technique (SIET), cell and tissue culture, confocal immunofluorescence analysis, transcriptomics, and proteomics. Work in the laboratory is complemented by field research in a diversity of locations, including the Queens University Biological Station in Ontario, the Bamfield Marine Station in British Columbia, Mongolia, China, the Andean Mountains of Peru, the Rift Valley of Africa, and the Brazilian Amazon. Motivated students and post-doctoral fellows can expect an exciting, highly interactive, and intellectually stimulating environment for research.
Research in the Nurse lab is elucidating the role of neurotransmitters in the peripheral control of breathing, and the cellular/molecular mechanisms that regulate O2 & CO2 / H+ chemosensing
Researchers in the O’Donnell lab have revealed interactions between detoxification and excretory mechanisms in insects and are also investigating how insect renal and gut tissues are controlled by neuropeptides.
Work by the McClelland lab is providing novel insight into how mice adapt to the low oxygen levels at high altitudes by adjusting energy metabolism
The Wilson lab is showing that chronic exposures of fish to human pharmaceuticals impacts fish reproduction and development
Research in the Scott lab is uncovering the respiratory and cardiovascular mechanisms of high-altitude adaptation in birds and mammals
