Geographic Genetic Divergence in Tychoplanktonic Taxa Dominating Diatom Communities in Marine Biofilms

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Here we intend to understand the dynamics of diatom communities in marine biofilms on plastics at different levels: how taxa are selected from the planktonic community and how communities are structured over time and on a large spatial scale. ABSTRACT Diatoms constitute the main photosynthetic group in marine biofilms throughout the world's oceans, in ...

Zooming in the plastisphere: the ecological interface for phytoplankton–plastic interactions in aquatic ecosystems

Biological Reviews, Volume 100, Issue 2, Page 834-854, April 2025.
ABSTRACT Phytoplankton is an essential resource in aquatic ecosystems, situated at the base of aquatic food webs. Plastic pollution can impact these organisms, potentially affecting the functioning of aquatic ecosystems. The interaction between plastics and phytoplankton is multifaceted: while microplastics can exert toxic effects on phytoplankton ...
