Osmoregulatory, metabolic and nutritional condition of summer-run male Chinook salmon in relation to their fate and migratory behavior in a regulated river
(Inter-Research, 2011-06-01)
We studied the migratory success of male summer-run Chinook salmon Oncorhynchus
tshawytscha in the Puntledge River on Canada’s Vancouver Island over a 3 yr period using biotelemetry and non-lethal physiological biopsy. ...
Feasting, fasting and freezing: energetic effects of meal size and temperature on torpor expression by little brown bats Myotis lucifugus
(Company of Biologists, 2010)
Torpor is an adaptation for energy conservation employed by many species of small-bodied endotherms. However, surprisingly little is known regarding proximate factors influencing day-to-day variation in torpor expression ...
Seasonal carryover effects of an experimental stressor in a wild teleost fish
(University of Chicago Press, 2010-10-08)
Stress can have sublethal effects that are manifested either immediately or at spatial or temporal scales that are removed from the stress event (i.e., carryover effects). We tested whether a short-term elevation of plasma ...
Glycerophospholipid Profiles of Bats with White-Nose Syndrome
(The University of Chicago, 2015)
Pseudogymnoascus destructans is an ascomycetous fungus responsible for the disease dubbed white-nose syndrome (WNS) and massive mortalities of cave-dwelling bats. The fungus infects bat epidermal tissue, causing damage to ...
Endangered Oarisma poweshiek larvae vary their graminoid forage in Manitoba, Canada
(Cambridge University Press, 2022)
The Poweshiek skipperling (Oarisma poweshiek) is endemic to the tall grass prairie in North America and is now critically endangered globally. Existing populations are scattered among tall grass prairie remnants. However, ...
Success stories and emerging themes in conservation physiology
(Oxford University Press and the Society for Experimental Biology, 2016)
The potential benefits of physiology for conservation are well established and include greater specificity of management techniques, determination of cause–effect relationships, increased sensitivity of health and disturbance ...
Physiological responses of three species of unionid mussels to intermittent exposure to elevated carbon dioxide
(Society for Experimental Biology, 2016-12-29)
Freshwater systems are at risk owing to increasing carbon dioxide (CO2) levels, and one of the possible reasons for these elevations is the deployment of non-physical fish barriers to prevent invasive fish movements. Carbon ...
Sphinx Moth Pollinations for the Endangered Western Prairie Fringed Orchid, Platanthera Praeclara in Manitoba, Canada
(Lepidopterists' Society, 2004)
The western prairie fringed orchid, Platanthera praeclara (Sheviak & Bowles), is an endangered species in North America. In Manitoba orchids produce lower numbers of seed capsules than more southern populations. Exploration ...
Activation of Innate Immune-Response Genes in Little Brown Bats (Myotis lucifugus) Infected with the Fungus Pseudogymnoascus destructans
(PLoS ONE, 2014-11-12)
Recently bats have been associated with the emergence of diseases, both as reservoirs for several new viral diseases in humans and other animals and, in the northern Americas, as hosts for a devastating fungal disease that ...
Spatial ecology of adult muskellunge (Esox masquinongy) in the urban Ottawa reach of the historic Rideau Canal, Canada
(EDP Sciences, 2010-07-19)
The Rideau Canal in Canada was constructed in the 1800s to enable strategic military and commercial transport in eastern Ontario between Lake Ontario and the Ottawa River. Today, the Rideau Canal is managed by Parks Canada ...
