Assessing Nutritional Condition of Mule Deer Using a Photographic Index
Understanding nutritional condition of animals can provide insight into underlying drivers of population dynamics. To estimate nutritional condition, indices require capture or mortality of animals to obtain measurements of body fat.

Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Neutral effects of low‐intensity dog training on northern bobwhite vital rates
Indirect effects of hunting can lead to changes in population dynamics, which can be caused by trait‐mediated effects such as, but not limited to, changes in behavior, reproduction, and physiological responses. Our understanding of the effects of activities associated with hunting such as dog training may incur trait‐mediated effects, and ultimately ...

Hunting regulations and movements of alpine reindeer
Most ungulate populations are regulated by hunting, and harvest rate is regulated through quotas and hunting season duration. Hunting is well known to affect behaviour of ungulates, but how annual variation in quotas and hunting season duration affects individual behaviour remains uncertain.

Hybridization is a natural process at species‐range boundaries that may variably promote the speciation process or break down species barriers but minimally will influence management outcomes of distinct populations.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

Annual survival in a dynamic species: pronghorn survival patterns across their northern range
Quantifying variation in demographic patterns, such as survival and recruitment, is critical for understanding population dynamics and informing evidence‐based and adaptive wildlife management. In this study, we leverage an extensive dataset from over 1000 GPS collared pronghorn Antilocapra americana to provide the first large‐scale evaluation of ...

Coursing the mottled mosaic: Generalist predators track pulses in availability of neonatal ungulates
The density and distribution of resources shape animal movement and behavior and have direct implications for population dynamics. Resource availability often is “pulsed” in space and time, and individuals should cue in on resource pulses when the ...

Understanding how prey species tradeoff predation risk and resource acquisition is particularly important for advancing our knowledge of predator–prey relationships. We investigated this by studying the use of concentrated anthropogenic resources, namely supplementary feeding sites, by roe deer Capreolus capreolus before and after grey wolf Canis lupus
