An assessment of prairie management practices for maintaining habitat quality for the endangered Poweshiek skipperling butterfly in Canada
(University of Notre Dame, 2022-08-10)
The Poweshiek skipperling (Oarisma poweshiek) was once a common prairie butterfly in central North America, but is now critically endangered in Canada and the United States. The Poweshiek skipperling is confined to the ...
Swimming activity of migrating Chinook salmon in a regulated river
(Inter-Research, 2012-10-17)
Adult Pacific salmon Oncorhynchus spp. have a fixed amount of energy available to
fuel their freshwater spawning migration, so they must optimize their activity in a manner that conserves energy to ensure successful ...
An Energy-Based Body Temperature Threshold between Torpor and Normothermia for Small Mammals
(The University of Chicago, 2007-09-05)
Field studies of use of torpor by heterothermic endotherms suffer from the lack of a standardized threshold differentiating torpid body temperatures (T_b) from normothermic T_b's. This threshold can be more readily observed ...
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 ...
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 ...
Urban drinking water quality : a survey of selected literature
(Institute of Urban Studies, 1993-01-01)
Water is indispensable for all life on our planet. The quantity of water on earth is finite, amounting to approximately 1500 million cubic kilometres (Morrison, 1984). It is one of the most precious resources that we have, ...
Energetic benefits of enhanced summer roosting habitat for little brown bats (Myotis lucifugus) recovering from white-nose syndrome
(2016)
Habitat modification can improve outcomes for imperilled wildlife. Insectivorous bats in North America face a range of conservation threats, including habitat loss and white-nose syndrome (WNS). Even healthy bats face ...
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 ...
