Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Subsistence hunting shapes the spatial variation of jaguar densities in community‐managed forests

Journal of Zoology, EarlyView.
Jaguars and people can coexist in community‐managed forests, but distance matters. In Guatemala's Maya Biosphere Reserve, jaguar numbers increased markedly in areas harder to reach on foot, yet jaguars were still found near communities, showing that responsibly managed forests can support jaguar populations while allowing people to maintain traditional

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

Journal of Zoology, EarlyView.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Interconnections of Water and Menstrual Justice: Understanding Water Justice as a Menstrual Justice Issue in Canada

Sexuality, Gender &Policy, Volume 9, Issue 3, August 2026.
ABSTRACT Menstrual justice is deeply interconnected with water justice, yet these topics remain largely siloed in policy and research—particularly in Canada, where water access is often assumed to be a non‐issue. However, existing literature reveals that inadequate water and infrastructure significantly affect menstrual hygiene, dignity, and health ...

Caracterización de las poblaciones de enemigos naturales de Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae)

Agrociencia, 2008
Piezodorus guildinii (Westwood) afecta a soja y leguminosas forrajeras provocando que en la primera se realicen todos los años entre una y dos aplicaciones de insecticidas. Con el objetivo de determinar, en soja y alfalfa, las fluctuaciones de las poblaciones de sus enemigos naturales y su eficacia, se realizaron muestreos en la Estación Experimental ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation
