Interactions between Corals and their Symbiotic Algae

Interactions between Corals and their Symbiotic Algae Gisèle Muller-Parker and Christopher F. D'Elia The mutualistic relationship between corals and their algal endosymbionts is a key factor in the evolutionary success of hermatypic (reef building) corals. Corals that harbor endosymbiotic algae exhibit faster rates of calcification, photoautotrophy and many other attributes that are believed to...

Freshwater Algae: Identification and Use as Bioindicators

Algae are widely present in freshwater environments, such as lakes and rivers, where they are typically present as micro-organisms – visible only with the aid of a light microscope. Although relatively inconspicuous, they have a major importance in the freshwater environment, both in terms of fundamental ecology and in relation to human use of natural resources. This book considers the diversit...

Coral symbiotic algae calcify ex hospite in partnership with bacteria.

Dinoflagellates of the genus Symbiodinium are commonly recognized as invertebrate endosymbionts that are of central importance for the functioning of coral reef ecosystems. However, the endosymbiotic phase within Symbiodinium life history is inherently tied to a more cryptic free-living (ex hospite) phase that remains largely unexplored. Here we show that free-living Symbiodinium spp. in cultur...

A green Paramecium strain with abnormal growth of symbiotic algae.

Some hundred cells of Chlorella-like green algae are naturally enclosed within the cytoplasm of a single cell of green paramecia (Paramecium bursaria). Therefore, P. bursaria serves as an experimental model for studying the nature of endo-symbiosis made up through chemical communication between the symbiotic partners. For studying the mechanism of symbiotic regulations, the materials showing su...
