Wildfire influences individual growth and breeding dispersal, but not survival and recruitment in a montane amphibian

Gabriel Barrile, Anna Chalfoun, Wendy Estes-Zumpf & Annika Walters
Global wildfire regimes are changing rapidly, with widespread increases in the size, frequency, duration, and severity of wildfires. Whereas the effects of wildfire on ecological state variables such as occupancy, abundance, and species diversity are relatively well-documented, changes in population vital rates (e.g., survival, recruitment) and individual responses (e.g., growth, movement) to wildfire are more limited because of the detailed information needed on the same individuals both pre- and post-fire. We capitalized on the 2018...

Cluster investigation results from model-predicted mountain lion feeding sites and non-predicted sites in southwest Wyoming

Justin Clapp
Global positioning system (GPS) receivers allow researchers to collect location data that provide information about fine-scale animal movements. For large carnivores, these data are routinely processed to identify clusters of GPS locations which are investigated to validate feeding sites, estimate prey species composition, and model the likelihood of predation events based on characteristics of GPS location data within clusters. Although developing predation models entails a high level of field effort, researchers are apprehensive in applying...

Heterogeneity in risk-sensitive allocation of somatic reserves in a long-lived mammal

Rachel Smiley, Rachel Smiley, Brittany L. Wagler, Tayler LaSharr, Kristin Denryter, Thomas Stephenson, Alyson Courtemanch, Tony Mong, Daryl Lutz, Doug McWhirter, Doug Brimeyer, Patrick Hnilicka, Blake Lowrey & Kevin Monteith
Patterns of food quality and availability, when combined with energetic demands in seasonal environments, shape resource acquisition and allocation by animals and hold consequences for life-history strategies. In long-lived species with extensive maternal care, regulation of somatic reserves of energy and protein can occur in a risk-sensitive manner, wherein resources are preferentially allocated to support survival at the cost of investment in reproduction. We investigated how Rocky Mountain bighorn sheep (Ovis canadensis), an alpine mammal...

Risky business: how an herbivore navigates spatio-temporal aspects of risk from competitors and predators

Katey Huggler, Joseph Holbrook, Matthew Hayes, Patrick Burke, Mark Zornes, Daniel Thompson, Justin Clapp, Patrick Lionberger, Miguel Valdez & Kevin Monteith
Understanding factors that influence animal behavior is central to ecology. Basic principles of animal ecology imply that individuals should seek to maximize survival and reproduction, which means carefully weighing risk against reward. Decisions become increasingly complex and constrained, however, when risk is spatiotemporally variable. We advance a growing body of work in predator-prey behavior by evaluating novel questions where a prey species is confronted with multiple predators and a potential competitor. We tested how fine-scale...

Spatiotemporal predictions of the alternative prey hypothesis: Predator habitat use during decreasing prey abundance

Mitchell Brunet, Kevin Monteith, Katey Huggler, Daniel Thompson, Patrick Burke, Mark Zornes, Patrick Lionberger, Miguel Valdez & Joseph Holbrook
The alternative prey hypothesis supposes that predators supported by a primary prey species will shift to consume alternative prey during a decrease in primary prey abundance. The hypothesis implies that during declines of one prey species, a predator modifies their behavior to exploit a secondary, or alternative, species. Despite occurring in many systems, the behavioral mechanisms (e.g., habitat selection) allowing predators to shift toward alternative prey during declines in the abundance of their primary prey...

Behavioral responses of a large, heat-sensitive mammal to climatic variation at multiple spatial scales

Tana L. Verzuh, Savannah Rogers, Paul Mathewson, Alex May, Warren Porter, Corey Class, Lee Knox, Teal Cufaude, L. Embere Hall, Ryan Long & Kevin Monteith
1. Climate warming creates energetic challenges for endothermic species by increasing metabolic and hydric costs of thermoregulation. Although endotherms can invoke an array of behavioral and physiological strategies for maintaining homeostasis, the relative effectiveness of those strategies in a climate that is becoming both warmer and drier is not well understood. 2. In accordance with the heat dissipation limit theory, which suggests that allocation of energy to growth and reproduction by endotherms is constrained by...

Cats and dogs: A mesopredator navigating risk and reward provisioned by an apex predator

Mitchell J. Brunet, Kevin Monteith, Katey Huggler, Justin Clapp, Daniel Thompson, Patrick Burke, Mark Zornes, Patrick Lionberger, Miguel Valdez & Joseph Holbrook
Successfully perceiving risk and reward is fundamental to the fitness of an animal, and can be achieved through a variety of perception tactics. For example, mesopredators may ‘directly’ perceive risk by visually observing apex predators, or may ‘indirectly’ perceive risk by observing habitats used by predators. Direct assessments should more accurately characterize the arrangement of risk and reward; however, indirect assessments are used more frequently in studies concerning the response of GPS-marked animals to spatiotemporally...
