Studies on the Bryophytes of Southern Manitoba. IV. Collections from Bird's Hill Provincial Park
(The Ottawa Field-Naturalists' Club, 1973)One hundred and seventeen taxa of bryophytes were collected in Bird's Hill Provincial Park, Manitoba. Habitats sampled included ditches, streams, marshes, moist clay banks, dry grassland, and areas forested by black spruce, ... -
Studies on the Bryophytes of Southern Manitoba. II. Collections from the Winnipeg Area
(The Ottawa Field-Naturalists' Club, 1973)Fifty-five taxa of bryophytes are reported for the area of Winnipeg, Manitoba. Frullania inflata, Brachythecium acuminatum, Encalypta ciliata, and Tortella inclinata are new records for the province. -
Studies on the Bryophytes of Southern Manitoba. V. Collections from Whiteshell Provincial Park
(The Ottawa Field-Naturalists' Club, 1973)One hundred and twenty-nine taxa of bryophytes were collected in the western part of Whiteshell Provincial Park, Manitoba. The following eight taxa have not previously been recorded for the province: Frullania bolanderi, ... -
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, ... -
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 ... -
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 ... -
Could localized warm areas inside cold caves reduce mortality of hibernating bats affected by white-nose syndrome?
(2009-03-05)White-nose syndrome (WNS) is a mysterious condition affecting populations of hibernating bats in the northeastern US. Little is known about its physiological effects on bats and no intervention has so far been proposed to ... -
Long-term effects of surgically implanted telemetry tags on the nutritional physiology and condition of wild freshwater fish
(Inter-Research, 2009-03-09)Little is known about the long-term consequences of surgically implanted telemetry devices on wild fish, as they are rarely recaptured. We used wild largemouth bass Micropterus salmoides as a model to evaluate the long-term ... -
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 ... -
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. ... -
Changes in Body Condition of Hibernating Bats Support the Thrifty Female Hypothesis and Predict Consequences for Populations with White-Nose Syndrome
(2011-06-22)White-nose syndrome (WNS) is a new disease of bats that has devastated populations in eastern North America. Infection with the fungus, Geomyces destructans, is thought to increase the time bats spend out of torpor during ... -
Hibernation energetics of free-ranging little brown bats
(Company of Biologists, 2012)Hibernation physiology and energy expenditure have been relatively well studied in large captive hibernators, especially rodents, but data from smaller, free-ranging hibernators are sparse. We examined variation in 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 ... -
Personality Variation in Little Brown Bats
(2013-11-27)Animal personality or temperament refers to individual differences in behaviour that are repeatable over time and across contexts. Personality has been linked to life-history traits, energetic traits and fitness, with ... -
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 ... -
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 ... -
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 ... -
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 ... -
Chill out: physiological responses to winter ice-angling in two temperate freshwater fishes
(Society for Experimental Biology, 2017-04-17)A large body of research has documented the stress response of fish following angling capture. Nearly all of these studies have taken place during the open-water season, with almost no work focused on the effects of capture ...
