The Historical and Overlooked Collapse of Medicinal Leeches in Spain

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Leeches in genus Hirudo have been used in medicine since ancient times, but increased exploitation during the 19th century led to the depletion of several populations in Europe. A compilation of Hirudo records in Spain (H. troctina Johnson, 1816 and H. verbana Carena, 1820) show that the genus was more commonly mentioned and widely distributed

Unprotected Waters: When Protection Fails In Freshwater

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Invasive species are a major driver of biodiversity loss in protected areas (PAs), yet their impacts in aquatic environments are less well documented. This study investigated the occurrence and distribution of nonnative freshwater fish in federal PAs in Brazil.

No ‘au doigt mouillé’: A Framework for Optimizing Barrier Prioritization Under Contrasting Governance and Cost Scenarios

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Restoring river connectivity through barrier removal is a key objective of contemporary river restoration policies, including the EU Nature Restoration Regulation. However, prioritizing which barriers to remove remains challenging because of limited resources, fragmented governance and uncertainty around costs and feasibility.

Anthropogenic Infrastructures Shape Brown Bear Movements in Human‐Modified Landscapes

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Human activities are major drivers of changes in animal behaviour, resulting in diverse spatial and temporal activity patterns across species. In this study, we analysed telemetry data from brown bears in Finland, Slovakia and Romania, to compare how human infrastructure influences their movement behaviour.
