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.

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...

A new acoustic telemetry tag that identifies carrier mortality by monitoring activity level

Methods in Ecology and Evolution, EarlyView.
Abstract We present a new acoustic telemetry tag capable of detecting whether its carrier stops moving for long enough to presume the organism has died, and of reporting the time elapsed since movement ceased. The tag uses existing environmental sensor technology together with an algorithm with user‐specifiable thresholds, and importantly, can separate

Computationally efficient Bayesian capture–mark–recapture models with transients, applied to survival of hand‐reared African Penguins

Methods in Ecology and Evolution, EarlyView.
Abstract Mark–recapture models are the primary framework for estimating demographic parameters in wild organisms. Complex life histories and sampling processes demand complex model formulations, yet these are vulnerable to errors in implementation and unanticipated biases.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Survival Remains High in Griffon Vultures 40 Years After Reintroduction

Animal Conservation, EarlyView.
The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management

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.
