Data from: Prairie dogs, cattle subsidies, and alternative prey: Seasonal and spatial variation in coyote diet in a temperate grassland

Susan Lingle, C-Jae M. Breiter, David B. Schowalter & John F. Wilmshurst
As the dominant predator on North America’s grasslands, coyotes (Canis latrans) have a large influence on biodiversity, both on working ranches and in protected parks. Ground squirrel (sciurid) species and livestock carrion are often abundant on grasslands worldwide and have the potential to influence a predator’s consumption of alternative prey. We collected 1321 scats in four seasons over two years in and adjacent to Grasslands National Park, Saskatchewan, to test the hypothesis that seasonal and...

Experimental manipulation of photoperiod influences migration timing in a wild, long-distance migratory songbird

Saeedeh Bani Assadi, Kevin Fraser & Kevin Charles Fraser
Previous laboratory studies have demonstrated the role of photoperiod in cueing the migration timing of small land birds; however, how migration timing of young birds in wild environments develops in relation to these cues have rarely been investigated. Such investigations can make important contributions to our developing understanding of the phenotypic plasticity of migration timing to new conditions with climate change, where changes in the timing of nesting may expose juvenile birds to different photoperiods....

Temperature shifts associated with bat arousals during hibernation inhibit the growth of Pseudogymnoascus destructans

Jamie Voyles, Ronny Forney, Gabriela Rios-Sotelo, Alexa Lindauer & Craig Willis
Temperature is a critically important factor in many infectious disease systems because it can regulate responses in both the host and the pathogen. White-nose syndrome (WNS) in bats is a severe infectious disease caused by the temperature-sensitive fungus, Pseudogymnoascus destructans (Pd). One feature of WNS is an increase in the frequency of arousal bouts (i.e., when bat body temperatures are elevated) in Pd-infected bats during hibernation. While several studies have proposed that increased frequency of...

Data for: Red foxes enhance long-term tree growth near the Arctic treeline

Jessica Lang, James Roth, Jacques Tardif & John Markham
Recent climate warming is expected to increase tree growth and productivity, substantially altering ecological function and boundaries in northern ecosystems. Temperature and precipitation largely determine the range and growth of trees in any biome, yet variations in microsite conditions can also influence tree growth on a finer scale. By altering essential resources and habitat conditions, terrestrial organisms could modify Subarctic tree growth. Red foxes (Vulpes vulpes) are found in most terrestrial ecosystems and are considered...
