Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

Wildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

Wildlife Biology, EarlyView.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.

Fate of orphans of Canada geese harvested by hunters in Connecticut, USA, depends upon which month the parents were killed

Wildlife Biology, EarlyView.
Little is known about what happens to juvenile birds after one or both of their parents are harvested by hunters during the post‐fledging dependency period. Here, we compare the fate of juvenile Canada geese Branta canadensis that lost ≥ 1 parent to hunters (orphans) during this period to other juveniles that retained both parents (non‐orphans). For 25

Beyond the enclosure: a decade of monitoring reveals altered traits in a European ground squirrel colony with implications for a recovery program

Wildlife Biology, EarlyView.
Effective integrated conservation programs critically depend on high‐quality animals from ex situ breeding, specifically those that are genetically diverse and physically healthy, yet insufficient scientific rigor in husbandry protocols can lead to unintended, detrimental consequences that compromise reintroduction success.

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Juvenile predation overwhelms nutritional effects on female ungulate fat reserves in a high‐predation system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ungulate body fat reserves reflect the nutritional environment, often serving as a useful indicator of bottom‐up resource availability. However, body fat reserves also integrate energetic costs associated with avoiding predation risk and reproductive effort, and it is ...
