Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, Volume 42, Issue 8, Page 1799-1817, October 2026.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

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

open access: yesConservation Science and Practice, Volume 8, Issue 10, October 2026.
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 ...

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

open access: yesIbis, Volume 168, Issue 4, Page 1210-1229, October 2026.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Variation in Bird Gut Microbiota Across Dietary Guilds and Migratory Strategies

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study analyzed the gut microbiota of birds from different ecological types in Nanning, Guangxi, and found that different dietary habits (omnivory, carnivory, and herbivory) and migratory strategies (migratory and resident) significantly altered the gut microbiota of birds, but migration did not increase the inter‐individual variability of gut ...
