Seabird‐vessel interactions in industrial fisheries of Northwest Africa: Implications for international bycatch management

open access: yesJournal of Applied Ecology, Volume 62, Issue 10, Page 2814-2831, October 2025.
This study provides guidance for seabird conservation by identifying high‐risk bycatch species and priority fishing fleets where mitigation should be targeted. It also demonstrates the potential of environmental variables to predict seabird–fishing interactions and underscores the political responsibilities essential for effective management in ...

Knowledge from non‐English‐language studies broadens contributions to conservation policy and helps to tackle bias in biodiversity data

open access: yesJournal of Applied Ecology, Volume 62, Issue 9, Page 2148-2162, September 2025.
Collecting data from local sources markedly further strengthens global biodiversity databases by adding species not previously included in international datasets. Furthermore, the addition of these data helps to understand spatial and temporal biases that potentially influence abundance trends at both national and global levels.

Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

open access: yesJournal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Assessing the current distribution and potential habitat availability for Kaempfer's tody‐tyrant: a restricted‐range and threatened species from the Atlantic Rainforest

open access: yesWildlife Biology, Volume 2025, Issue 4, July 2025.
Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes are more likely to become extinct. The prevention of extinctions is an urgent matter and knowledge on the ecology and distribution of threatened species is required to outline conservation strategies.
