Assessing group size and the demographic composition of a canopy‐dwelling primate, the northern muriqui (Brachyteles hypoxanthus), using arboreal camera trapping and genetic tagging

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...

A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

Assessing the viability of airborne environmental DNA detection for identifying trafficked lion pelts (Panthera leo) in a containerised environment

open access: yesFrontiers in Conservation Science
Accurate and rapid detection methodologies for monitoring the illicit trafficking of threatened species through highly exploited maritime routes are crucial to support law enforcement and conservation efforts. One of the most prominent trafficked species

Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

Hunting, but not outdoor recreation, modulates behavioural tolerance to human disturbance in Alpine marmots Marmota marmota

open access: yesWildlife Biology, EarlyView.
Humans are often perceived as predators by free‐living animals, and thus, even non‐consumptive human activities such as outdoor recreation may trigger behavioural and physiological responses, often with negative consequences on individual fitness and population persistence.

A framework for the ethical use of animal‐borne devices in post‐release monitoring following rehabilitation

open access: yesWildlife Biology, EarlyView.
Rehabilitation and release contribute to conservation efforts for threatened species. Ensuring that these efforts are effective requires a good understanding of the factors which determine survival and integration of released animals into wild populations.

Navigating a landscape of contrasting hunting regimes and habitats: red deer responses to risk and resources

open access: yesWildlife Biology, EarlyView.
Habitat selection of ungulates is influenced by various factors, with human interactions playing a significant role. Human disturbances through hunting strongly affect ungulate behaviour, often forcing them to modify their habitat choices by avoiding areas where the risk from humans outweighs other habitat benefits. Gaining insights into these dynamics

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

open access: yesWildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

open access: yesWildlife Biology, EarlyView.
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 ...

Field test of assumptions for using line transect distance sampling on rock ptarmigan

open access: yesWildlife Biology, EarlyView.
Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.
