Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, EarlyView.
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.

Occurrence of Novel and Legacy Per/Polyfluoroalkyl Substances (PFASs) in Scopoli’s Shearwater (Calonectris diomedea) Feathers

Diversity
Per- and polyfluoroalkyl substances (PFASs) are contaminants of great concern due to their ubiquitous environmental occurrence in the environment and their potential adverse effects on organisms.

A comparison of two seabird communities on opposite coasts of the Alborán Sea (western Mediterranean)

Scientia Marina, 2003
We compared the seabird communities at two sites of the southern and northern shores of the Alborán Sea in the Western Mediterranean (Melilla and Adra respectively) during a whole year. Similarities and differences in environmental characteristics of the

Biodiversity research requires more motors in air, water and on land

Methods in Ecology and Evolution, EarlyView.
Abstract Human activities have accelerated species extinctions, driving rapid biodiversity decline. Simultaneously, advancements in Artificial Intelligence (AI) and autonomous systems offer transformative potential for biodiversity research. Uncrewed vehicles—drones (aerial systems) and other robots (ground and underwater platforms)—equipped with high ...

Diversity of Culturable Yeasts in the Feces of Mew Gulls Breeding in Natural and Urban Habitats, with Insights into the Antifungal Susceptibility of the Observed Pathogens

Birds
Migratory birds play an important role in the spread of yeasts in the environment over long distances and in different geographical regions. Human activities, in turn, have a major impact on the biology of wild birds and, consequently, on the microbial ...

Variable sea‐ice conditions influence trophic dynamics in an Arctic community of marine top predators

Ecology and Evolution, 2019
Sea‐ice coverage is a key abiotic driver of annual environmental conditions in Arctic marine ecosystems and could be a major factor affecting seabird trophic dynamics.

Airborne Remote Sensing of a Biological Hot Spot in the Southeastern Bering Sea

Remote Sensing, 2011
Intense, ephemeral foraging events within localized hot spots represent important trophic transfers to top predators in marine ecosystems, though the spatial extent and temporal overlap of predators and prey are difficult to observe using traditional ...

Nest Survival Models and Genomics Illuminate Hybridisation Attempts, Guiding Culturally Informed Management to Recover a Critically Endangered Seabird

Animal Conservation, EarlyView.
Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.
