Hierarchical Modelling of Aquatic Species Distributions
Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.ABSTRACT Aim Species Distribution Models (SDMs) have traditionally been developed in a terrestrial context, and their application to aquatic ecosystems presents unique challenges. These include predicting species distributions across spatially constrained environments and incorporating environmental drivers that operate across nested spatial scales. We

Demographic buffering in natural populations: A multi‐level perspective
Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Climatic niche position predicts population dynamics in Mediterranean shrubs after drought
Journal of Ecology, Volume 114, Issue 8, August 2026.Climatic conditions closer to the species' climatic niche centroid generally resulted in higher population growth in two Mediterranean shrubs, but demographic responses differed between species and were further influenced by drought‐induced vegetation die‐off.

Environmental factors influencing the distribution of Arvicola scherman (Shaw, 1801) at the southwestern edge of its distribution [PDF]
Munibe Ciencias Naturales, 2015 En 2008 se detectó la existencia de daños en pastizales de la montaña oriental de la provincia de Lugo (NW Spain), probablemente ligados un aumento de las poblaciones de Arvicola scherman (Shaw, 1801). Existe muy poca información sobre esta especie en la

BIMr2: Inference of migration rates and their drivers from multilocus genotypes
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2330-2342, August 2026.Abstract Understanding how environmental factors drive recent migration is crucial for predicting species' responses to habitat change and for informing conservation strategies. There is one method available (BIMr) aimed at identifying the environmental factors associated with migration patterns using genetic data.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, Volume 40, Issue 4, August 2026.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.
