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

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, plastics can also act as a substrate for colonisation.

Two species? - Limits of the species concepts in the pygmy grasshoppers of the complex (Orthoptera, Tetrigidae).

Today, integrative taxonomy is often considered the gold standard when it comes to species recognition and delimitation. Using the complex, we here present a case where even integrative taxonomy may reach its limits. The complex consists of two morphs, and , which are easily distinguished by a single character, the length of the hind wing.
