Data from: Prelude to a panzootic: gene flow and immunogenetic variation in northern little brown myotis vulnerable to bat white-nose syndrome

Christina M. Davy, Michael E. Donaldson, Yessica Rico, Cori L. Lausen, Kathleen Dogantzis, Kyle Ritchie, Craig K. R. Willis, Douglas W. Burles, Thomas S. Jung, Scott McBurney, Allysia Park, Donald J. McAlpine, Karen F. Vanderwolf, Christopher J. Kyle & Craig K.R. Willis
The fungus that causes bat white-nose syndrome (WNS) recently leaped from eastern North America to the Pacific Coast. The pathogen’s spread is associated with the genetic population structure of a host (Myotis lucifugus). To understand the fine-scale neutral and immunogenetic variation among northern populations of M. lucifugus, we sampled 1142 individuals across the species’ northern range. We used genotypes at 11 microsatellite loci to reveal the genetic structure of, and directional gene flow among, populations...

Data from: Multi-species genetic connectivity in a terrestrial habitat network

Robby R. Marrotte, Jeff Bowman, Michael G. C. Brown, Chad Cordes, Kimberley Y. Morris, Melanie B. Prentice & Paul J. Wilson
Background: Habitat fragmentation reduces genetic connectivity for multiple species, yet conservation efforts tend to rely heavily on single-species connectivity estimates to inform land-use planning. Such conservation activities may benefit from multi-species connectivity estimates, which provide a simple and practical means to mitigate the effects of habitat fragmentation for a larger number of species. To test the validity of a multi-species connectivity model, we used neutral microsatellite genetic datasets of Canada lynx (Lynx canadensis), American marten...

Data from: Nutritional state reveals complex consequences of risk in a wild predator–prey community

Philip D. DeWitt, Matt S. Schuler, Darcy R. Visscher, Richard P. Thiel & Matthew S. Schuler
Animal populations are regulated by the combined effects of top-down, bottom-up and abiotic processes. Ecologists have struggled to isolate these mechanisms because their effects on prey behaviour, nutrition, security and fitness are often interrelated. We monitored how forage, non-consumptive effects (NCEs), consumptive predation and climatic conditions influenced the demography and nutritional state of a wild prey population during predator recolonization. Combined measures of nutrition, survival and population growth reveal that predators imposed strong effects on...

Data from: Compensatory selection for roads over natural linear features by wolves in northern Ontario: implications for caribou conservation

Erica J. Newton, Brent R. Patterson, Morgan L. Anderson, Arthur R. Rodgers, Lucas M. Vander Vennen & John M. Fryxell
Woodland caribou (Rangifer tarandus caribou) in Ontario are a threatened species that have experienced a substantial retraction of their historic range. Part of their decline has been attributed to increasing densities of anthropogenic linear features such as trails, roads, railways, and hydro lines. These features have been shown to increase the search efficiency and kill rate of wolves. However, it is unclear whether selection for anthropogenic linear features is additive or compensatory to selection for...

Data from: Establishing detection thresholds for environmental DNA using receiver operator characteristic (ROC) curves

Natasha R. Serrao, Scott M. Reid & Chris C. Wilson
Environmental DNA (eDNA) detection is increasingly being used to assess the potential presence of aquatic species. Setting defensible thresholds for qPCR assays are necessary to differentiate “detection” from “non-detection”, but threshold rationales are rarely reported in eDNA studies. Detection thresholds for data inclusion and exclusion have implications for downstream data analysis; uncritical acceptance could result in false positive results (Type I error), whereas overly conservative thresholds could result in high false negative interpretation (Type II...

Data from: Comparison of diets for largemouth and smallmouth bass in Eastern Lake Ontario using DNA barcoding and stable isotope analysis

Erich J.H. Nelson, Jeremy Holden, Robert Eves, Bruce Tufts & Erich J. H. Nelson
Largemouth (LMB: Micropterus salmoides) and Smallmouth Bass (SMB: Micropterus dolomieu) are important species in the recreational fisheries of the Laurentian Great Lakes. The invasion of the Round Goby (Neogobius melanostomus) into these lakes has changed several facets of black bass biology, but there is still much to learn about the relationship between these species. Previous dietary analyses have shown Round Goby to be important prey for bass, but have been limited by low visual identification...
