Assessing and quantifying variations in the functioning of marine food webs across scales

open access: yesConservation Biology, EarlyView.
Abstract The mismatch between the scale of ecological processes and management decisions represents a significant challenge in marine conservation. This misalignment can result in ineffective conservation measures and compromise the sustainability of marine ecosystems.

A framework to assess trajectories of societal and biological extinction

open access: yesConservation Biology, EarlyView.
Abstract Threatened species that are societally extinct, which refers to the loss of a species’ presence in human societies, are less likely to receive conservation attention, potentially resulting in their biological extinction going unnoticed. However, little is known about the process and forms of such extinction.

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

open access: yesIbis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Revisiting avian wingtip shape indices: a comparison of methods with empirical data

open access: yesIbis, EarlyView.
The study of avian wing shape helps in understanding how birds can adapt to their habitats and respond to changing environmental conditions. An important challenge in this endeavour is obtaining estimates of wing shape that are truly independent of body size, particularly when there is an allometric relationship between them. Size‐constrained component

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...
