Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

open access: yesConservation Science and Practice, EarlyView.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2190-2213, October 2026.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Variation in isotopic niche partitioning between adult roseate and common terns in the Northwest Atlantic

open access: yesEndangered Species Research, 2023
Co-occurring species with similar resource requirements often partition ecological niches at different spatial and temporal scales. In the Northwest Atlantic (NWA), federally endangered roseate terns Sterna dougallii nest almost exclusively in coastal ...

Connectivity between breeding sites, wintering areas, and migration routes in Common Terns (Sterna hirundo) breeding in the Western Palaearctic

open access: yesIbis, Volume 168, Issue 4, Page 1230-1240, October 2026.
Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

Colony size as a predictor of breeding behaviour in a common waterbird.

open access: yesPLoS ONE, 2020
The choice of colony size may have profound consequences for individual fitness in colonially breeding birds, but at the same time it may require certain behavioural adaptations.

Nest success of ground‐nesting ducks in the wetlands of Great Salt Lake, Utah

open access: yesEcology and Evolution, 2023
The number of ground‐nesting ducks in the wetlands of Great Salt Lake, Utah has drastically decreased in the past few decades. A potential cause for this decline is the increase of predator species and their abundances, which has caused most nests to ...

Reproductive Drivers of Temporal Telomere Dynamics in Female Tree Swallows

open access: yesMolecular Ecology, Volume 35, Issue 18, September 2026.
ABSTRACT Understanding trade‐offs between life‐history traits, particularly between reproductive investment and somatic maintenance, remains a major challenge in evolutionary ecology. Telomeres progressively shorten with age and have been suggested as good predictors of survival and longevity.
