Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, EarlyView.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Veterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and
