Urbanization impacts apex predator gene flow but not genetic diversity across an urban-rural divide

Apex predators are important indicators of intact natural ecosystems. They are also sensitive to urbanization because they require broad home ranges and extensive contiguous habitat to support their prey base. Pumas (Puma concolor) can persist near human developed areas, but urbanization may be detrimental to their movement ecology, population structure, and genetic diversity. To investigate potential effects of urbanization in population connectivity of pumas, we performed a landscape genomics study of 130 pumas on the...

Data from: Extreme site fidelity as an optimal strategy in an unpredictable and homogeneous environment

Brian D. Gerber, Mevin B. Hooten, Christopher P. Peck, Mindy B. Rice, James H. Gammonley, Anthony D. Apa & Amy J. Davis
1. Animal site fidelity structures space-use, population demography, and ultimately gene flow. Understanding the adaptive selection for site fidelity patterns provides a mechanistic understanding to both spatial and population processes. This can be achieved by linking space-use with environmental variability (spatial and temporal) and demographic parameters. However, rarely is the environmental context that drives the selection for site fidelity behavior fully considered. 2. We use ecological theory to understand whether the spatial and temporal variability...

Data from: Feline immunodeficiency virus in puma: estimation of force of infection reveals insights into transmission

Jennifer Reynolds, Scott Carver, Mark Cunningham, Ken Logan, Winston Vickers, Kevin Crooks, Sue VandeWoude & Meggan Craft
Determining parameters that govern pathogen transmission (such as the force of infection, FOI), and pathogen impacts on morbidity and mortality, is exceptionally challenging for wildlife. Vital parameters can vary, for example across host populations, between sexes and within an individual's lifetime. Feline immunodeficiency virus (FIV) is a lentivirus affecting domestic and wild cat species, forming species-specific viral--host associations. FIV infection is common in populations of puma (Puma concolor), yet uncertainty remains over transmission parameters and...

Data from: Mesopredators change temporal activity in response to a recolonizing apex predator

Carolyn R. Shores, Justin A. Dellinger, Eric S. Newkirk, Shannon M. Kachel & Aaron J. Wirsing
Apex predators can influence ecosystems through density and behaviorally mediated effects on herbivores and mesopredators. In many parts of the world, apex predators live in, or are returning to, landscapes that have been modified by people, so it is important to understand their ecological role in anthropogenic landscapes. We used motion-activated game cameras to compare the activity patterns of humans and two mesopredators, coyotes (Canis latrans) and bobcats (Lynx rufus), in areas with and without...

Data from: Mismatches between breeding phenology and resource abundance of resident alpine ptarmigan negatively affect chick survival

Gregory T. Wann, Cameron L. Aldridge, Amy E. Seglund, Sara J. Oyler-McCance, Boris C. Kondratieff & Clait E. Braun
1. Phenological mismatches – defined here as the difference in reproductive timing of an individual relative to the availability of its food resources – occur in many avian species. Mistiming breeding activities in environments with constrained breeding windows may have severe fitness costs due to reduced opportunities for repeated breeding attempts. Therefore, species occurring in alpine environments may be particularly vulnerable. 2. We studied fitness consequences of timing of breeding in an alpine-endemic species, the...
