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. ...
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 ...
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, ...
Evidence of Late-Summer Mating Readiness and Early Sexual Maturation in Migratory Tree-Roosting Bats Found Dead at Wind Turbines
(2012-10)
Understanding animal mating systems is an important component of their conservation, yet the precise mating times for many species of bats are unknown. The aim of this study was to better understand the details and timing ...
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 ...
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, ...
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 ...
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, ...
