Sailing Through Time: Building Pacific Maritime Resilience

Global Policy, EarlyView.
ABSTRACT This article examines the Pacific Blue Shipping Partnership (PBSP), an ambitious initiative aimed at decarbonising maritime transport across Oceania. The study explores the cultural, historical and technological aspects of wind‐propelled shipping in the Pacific.

Spatial signatures of group cohesion

Methods in Ecology and Evolution, EarlyView.
Abstract Wildlife populations are undergoing unprecedented changes to their spatial distributions as a result of human activities. Innovative approaches are needed to document these changes, especially in cases where sampling is sparse. Here, we contribute to the tools available in spatial ecology by developing novel metrics based on the coefficient of

Spatially realistic dynamic N‐mixture models

Methods in Ecology and Evolution, EarlyView.
Abstract Dispersal is a complex ecological process that can be driven by the abiotic environment, density‐dependent processes and species mobility. Traditionally, dispersal has been studied with capture‐based data that are often limited in space and time. More recently, spatial dynamic N‐mixture models (i.e.

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 ...

Beyond the Individual: Multisite Population‐Level Consequences of Road Mortality on a Declining Mammal

Animal Conservation, EarlyView.
We used a comparative study design to quantify population densities, structure, survival, cause‐specific mortality and female productivity in four West‐European hedgehog (Erinaceus europaeus) populations, and to forecast the impact of road mortality on population viability.

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.

Capture‐recapture

American Ethnologist, 2022
ABSTRACTCapture‐recapture, a method devised for estimating wildlife population sizes using technologies like bird banding, has been repurposed for use with “rare and elusive” human populations. Capture‐recapture is implemented to count “key populations,” groups that constitute a small portion of the general population but are at high risk of HIV ...

A Bayesian, combinatorial approach to capture–recapture

Theoretical Population Biology, 2006
It is shown that, in the capture-recapture method, the widely used formulae of Bailey or Chapman-Seber give the most likely value for the size of the population, but systematically underestimate the probability that the population is larger than any given size.
