First report of Epibiont ciliates (Ciliophora: Peritrichia) living on larvae of Leptophlebiidae (Ephemeroptera) from Brazil

Brazilian Archives of Biology and Technology, 2017
Epibiosis was understood as a commensalism relation between two or more organisms. However, some studies have shown that epibionts can cause deleterious effects to their host.

Review of the fauna associated with wild and farmed mussels and oysters in the Mediterranean

Biological Reviews, EarlyView.
ABSTRACT Mussels and oysters are important ecosystem engineers which modify the physical and chemical characteristics of the environment and create habitats that support highly diverse associated communities. In the Mediterranean Sea, the native Mediterranean mussel Mytilus galloprovincialis and the European flat oyster Ostrea edulis, together the ...
