Urbanization Intensity, Vegetation Cover and Plant Vigor Affects Stem Galls Occurrence and Abundance in a Widely Distributed Ruderal Tropical Plant

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
In this study, we demonstrate that urbanization intensity reduces the abundance of stem galls on Turnera subulata, while increased vegetation cover and plant vigor promote higher occurrence and abundance. These findings highlight the importance of native vegetation in sustaining specialized insect‐plant interactions and provide evidence that plant ...

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.

Predictions of southern migration timing in coastal sharks under future ocean warming

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Effects of Long‐Term Nutrient Addition on Leaf Metabolites, Herbivory, and Mycorrhizal Spores Associated With a Savannah Woody Species

open access: yesAustral Ecology, Volume 50, Issue 11, November 2025.
ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated
