Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...
