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

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.

Estimating the Population Size of Masked Palm Civets Using Hair-Snaring in Southwest China
Mesocarnivores are major components of carnivore assemblages, and they play important roles in structuring communities and regulating community dynamics.

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 ...

We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

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.

Abstract Studies on the earliest life stages are essential to our ecological understanding of avian demography; however, monitoring technologies that allow tracking of small birds are still limited in a variety of ways. One critical limitation, until recently, has been the development of methods for attaching transmitters to young birds with precocial ...

Counting spots: Leopard density along a gradient of conservation rigor
Leopards are widely distributed throughout Africa, Asia and the Middle East, but have suffered substantial range contractions and population declines.

Abstract Many waterfowl species and closely related congeners are shared across the Holarctic, and are culturally and economically important in both North America and Europe. Accordingly, both continents have developed science and management frameworks in an attempt to establish evidence‐based conservation practices for this guild of birds.

Abundance, trends, and challenges facing mountain goats throughout their North American distribution
Our survey of states and provinces revealed that 13% of native mountain goat populations increased during the past 10 years, whereas 38% declined. For introduced populations, increases were roughly equal to declines. Rates of change were positively associated with being introduced or pioneering, and negatively associated with heavy snow, and, to a ...
