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 ...
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 ...
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 ...
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 ...
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 ...
Endangered Oarisma poweshiek butterfly larval foraging and adult habitat interactions in Manitoba, Canada
(University of Winnipeg, 2021-10-29)
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 amongst tall grass prairie remnants. However, ...
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 ...
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 ...
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 ...
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 ...
