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 ...
Egg Laying Behaviour and Larval Shelter-Construction Patterns of the endangered Mottled Duskywing (Erynnis martialis) in Canada
(The Lepidopterists' Society, 2022-03-09)
The Mottled duskywing (Erynnis martialis) butterfly is endangered, living in pine forests and oak barrens in Canada and the eastern United States of America. While host plants and larval behaviour is documented in Mottled ...
Context-dependent conservation responses to emerging wildlife diseases
(Ecological Society of America, 2015)
Emerging infectious diseases pose an important threat to wildlife. While established protocols exist for combating outbreaks of human and agricultural pathogens, appropriate management actions before, during, and after the ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
