Enriching historical biologging datasets on seabirds using deep neural networks: A transformer‐based approach to infer energy expenditure proxy from GPS and environmental data

Methods in Ecology and Evolution, EarlyView.
Abstract Recent advances in biologging have led to the widespread use of accelerometers, which generate high‐resolution movement data essential for understanding animal behaviour. Derived from tri‐axial accelerometry, Overall Dynamic Body Acceleration (ODBA) serves as a proxy for energy expenditure that is less invasive and more cost‐effective than ...

A continuous‐time random encounter and staying time (REST) model: Moving beyond temporal aggregation in camera‐trap density estimation

Methods in Ecology and Evolution, EarlyView.
Abstract Estimating wildlife population density is fundamental to ecology and conservation. While camera traps have revolutionized the monitoring of medium‐ to large‐sized mammals, estimating the density of unmarked populations remains a major challenge. Current models rely on a critical and often‐violated synchronized activity assumption.

Residual diagnostics for assessing closed population capture–recapture models

Methods in Ecology and Evolution, EarlyView.
Abstract Capture–recapture models provide a statistical framework for estimating demographic parameters from incomplete observation data, where not all individuals in a population are detected during sampling. Assessing the fit of such models is crucial for reliable inference.

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

Animal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.

Potential vs. Realized Large Carnivore Density: The Influence of Livestock on Carnivore Carrying Capacity Estimation

Animal Conservation, EarlyView.
In an unfenced mixed‐use savanna landscape in Namibia, we compared realized densities of leopards and cheetahs estimated using spatial capture–recapture models with prey‐based carrying capacity predictions. Leopard densities exceeded predictions based on wild prey alone but closely matched livestock‐supplemented models, suggesting that vulnerable ...

Running towards: Labour market incentives for runaway slaves in the British Cape Colony, 1830–1838

Asia‐Pacific Economic History Review, EarlyView.
Abstract Recent scholarship on slave escapes has increasingly emphasised economic motivation, but few studies have empirically investigated how market incentives influenced the decision‐making of enslaved individuals during transitions from coerced to wage labour.

A nonlinear association between chronic stress and instrumental reward learning under Pavlovian conflict: Behavioural and computational evidence

British Journal of Psychology, EarlyView.
Abstract Chronic stress, arising from prolonged exposure to unpredictable challenges, is common in everyday life and may alter cognitive processes. However, few human studies have empirically examined the association between chronic stress and reward learning, which is critical for navigating uncertain environments.

Resilience Processes Facilitating the Transition to Adulthood Among At‐Risk Young Adult Arabs in Israel

Child &Family Social Work, EarlyView.
ABSTRACT Resilience has been acknowledged as an important aspect of a holistic understanding of emerging adults who face structural and cultural challenges. As such, it serves as a framework for empirical research to examine the processes through which minoritized young adults navigate and better adapt to intersectional stressors across sociopolitical,

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

Conservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.
