Genetic population structure of red foxes Vulpes vulpes across a rural landscape: insights into population connectivity and spatial patterns

Wildlife Biology, EarlyView.
Human activities have shaped and are continuing to influence terrestrial landscapes, creating heterogenous, and often, fragmented landscapes. Generalist species, like the red fox Vulpes vulpes, show high flexibility in habitat use, and occur across the heterogeneous, anthropogenic landscapes of central Europe.

Cortisol concentrations in hair are biomarkers of health status and seasonal change, but not urbanisation, in wolves

Wildlife Biology, EarlyView.
Wolves have reclaimed much of their former range in Europe, including areas with a high human footprint, yet the physiological impacts of human‐associated stressors remain poorly understood. We first examined methodological factors affecting hair cortisol concentrations (HCC) in wolves by using a ‘shave/re‐shave' design to assess hair growth rate and ...

Road mortality mitigation for red wolves requires a landscape approach

Wildlife Biology, EarlyView.
In 1980, the red wolf Canis rufus was declared extinct in the wild. However, starting in 1987, a captive breeding program allowed for a reintroduction effort in and around Alligator River National Wildlife Refuge (Alligator River NWR), North Carolina, USA. In 2012 the wild red wolf population peaked at about 120 individuals.

Life‐history stages and behavior influence demographic classification of moose captured on remote cameras

Wildlife Biology, EarlyView.
Obtaining accurate information on demographic states, such as the age and sex classes of animals, is an important step for monitoring wildlife populations. Traditionally, demographic data are collected from harvest, aerial surveys and telemetry studies.

Availability bias and responsive movement during ground‐based wildlife surveys revealed by concurrent thermal drone surveys

Wildlife Biology, EarlyView.
Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.

Selectivity and efficiency of predator control methods: a case study from a Mediterranean hunting ground

Wildlife Biology, EarlyView.
Predator control is a widely used management tool worldwide to reduce the impact of opportunistic predatory species, but in some contexts where predators are controlled to reduce negative impacts on game species, there are concerns about the selectivity and efficiency.

Anecdotes or Ecological Patterns: Symbiotic Foraging Behaviors in Coyotes and Badgers 奇特模式还是生态格局: 郊狼与獾的共生觅食行为

Wildlife Letters, EarlyView.
Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

Wildlife Letters, EarlyView.
We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Spatiotemporal mapping the usable space of free‐roaming equids across the western United States

Wildlife Society Bulletin, EarlyView.
Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained
