Importance of within-shoot epiphyte distribution for the carbon budget of seagrasses: the example of Posidonia oceanica

To assess the effects of shading by epiphytes on the carbon balance of the seagrass Posidonia oceanica, we examined the patterns of within-shoot epiphyte abundance on leaves, and their variability with season and depth...

Effect of solar irradiance on lipids of the green alga Ulva fenestrata Postels et Ruprecht

We examined variations in lipid composition of the marine green alga Ulva fenestrata grown under different irradiance conditions (80% of incident photosynthetically active radiation [PAR] and 24% PAR)...

Effect of light intensity on the fatty acid composition of dinoflagellates symbiotic with hermatypic corals

We examined the effects of varying light intensity on fatty acid composition in symbiotic dinoflagellates (SD) isolated from hermatypic corals Millepora intricata, Pocillopora damicornis, Seriatopora caliendrum, Seriatopora hystrix and Stylophora pistillata...
