Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

Journal of Animal Ecology, Volume 95, Issue 7, Page 1248-1259, July 2026.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show

Non‐native parrot species expand the trait space of avian communities by filling empty niches in urban areas

Ibis, Volume 168, Issue 3, Page 1055-1070, July 2026.
Non‐native species are one of the greatest threats to biodiversity worldwide due to their direct and indirect effects on native communities. There are two opposing hypotheses to explain how non‐native species successfully establish outside their native range.

Balancing conflict and coexistence: Interactions between invasive monk parakeets and native urban birds

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Biological invasions often generate complex ecological paradoxes, particularly when invasive species act as ecosystem engineers that simultaneously compete with and benefit native communities. Understanding these dual dynamics is critical for managing urban biodiversity.

Beyond species loss: Community reshuffling shapes biodiversity along the urban–rural gradient

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results indicate that species turnover is a general ecological mechanism shaping vertebrate communities along the urban gradient, driven by taxon‐ and species‐specific responses to environmental and spatial features. Community differences primarily reflect habitat suitability rather than dispersal limitation, highlighting the potential of targeted ...

Presence of the alien rose-ringed parakeet Psittacula krameri (Psittacidae) in Mozambique

, 2023
The biology of the Rose-ringed Parakeet Psittacula krameri has been widely studied in many of its naturalized habitats around the world. However, its potential status and impacts may have gone unnoticed in regions with limited monitoring. In this report,
