Downscaling global reference points to assess the sustainability of local fisheries
Conservation Biology, Volume 39, Issue 3, June 2025.Abstract Multispecies coral reef fisheries are typically managed by local communities who often lack research and monitoring capacity, which prevents estimation of well‐defined sustainable reference points to perform locally relevant fishery assessments.

Molecular Ecology, Volume 34, Issue 11, June 2025.ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

People and Nature, Volume 7, Issue 4, Page 871-886, April 2025.Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.

, 2011 Reef fishes play a fundamental role in many ecological processes of coral reef ecosystems. Genetic studies of reef fishes around the world have revealed that even though they may harbor high levels of mitochondrial genetic diversity, several species present genetic footprints of historical demographic fluctuations brought about by climatic changes ...

Island restoration to rebuild seabird populations and amplify coral reef functioning
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...
