Biogeographical Distribution of River Microbial Communities in Atlantic Catchments
Environmental Microbiology Reports, Volume 17, Issue 1, February 2025.We discovered different factors affecting river microbial communities (RMC) diversity and composition across Atlantic catchments in Europe. Prokaryote diversity was mainly influenced by topography and geology, while eukaryotic groups were driven by land use and cover.

Plant Pathology, Volume 74, Issue 2, Page 330-362, February 2025.High diversity of known and new, mostly exotic Phytophthora species in forests, nurseries and streams across Portugal and numerous associated forest tree declines are a consequence of long‐term plant introductions and outplantings. Abstract Between 2010 and 2015, an extensive survey of Phytophthora diversity was performed across Portugal.
