Feeding of Aurelia sp. (Scyphozoa) and links to the microbial food web

A large fraction of primary production is recycled through a marine protozoa–bacterioplankton predator– prey chain in most aquatic ecosystems. The size of food resources and the ratio between predators and prey determine the organic matter transfer through the ‘classical’ or the ‘microbial’ pathway (Azam et al. 1983). The effect of grazers on the prey can play an important role in selectivity a...

Molecular evidence for cryptic species of Aurelia aurita (Cnidaria, Scyphozoa).

Morphological taxonomy suggests that marine faunas are species poor compared to terrestrial and freshwater faunas (1). This dichotomy has been attributed to the unique potential of marine plankters for distant dispersal across homogenous oceans with few barriers to gene flow (2). The relative scarcity of opportunities for allopatric divergence has resulted in depauperate marine faunas character...
