Assessing responses of reef island seabirds to environmental and anthropogenic drivers

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

open access: yesOikos, Volume 2026, Issue 9, September 2026.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 8, August 2026.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Global patterns and processes of establishment risk by non‐indigenous marine fish

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
Niche overlap may be critical to consider, even in areas that appear environmentally unsuitable or poorly connected for NIS. Preserving the intrinsic biotic resistance posed by native species can improve the effectiveness of targeted conservation measures.
