Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Structured decision‐making as a framework to incorporate social equity into conservation decisions

Conservation Biology, EarlyView.
Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

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

Predictive evolutionary genomics: principles, validation, and practice

New Phytologist, EarlyView.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, Volume 24, Issue 8, August 2026.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped
