The seas provided a suitable site for the early evolution of all life. Ever since plants and animals developed structures and mechanisms that enabled them to survive on land, terrestrial and aquatic plants have been exposed to different abiotic and biotic selective pressures. Marine plants, which, unlike terrestrial plants, have evolved and adapted to life in a largely stable but saline environ...

Photoinhibition of macroalgae in the epilithic algal community (EAC) of coral reefs was studied using chlorophyll fluorescence techniques at One Tree Island, Great Barrier Reef, Australia. F jFm (variable to maximum fluorescence darkened samples) of shallow macroalgae declined by 50% on fine summer and winte~ days, reco.vering i~ late afternoon. Within a species, thalh from low-hght habItats we...

c-AMP dependent protein kinase (protein kinase A, PKA) is an important enzyme involved in the regulation of an increasing number of physiological processes including immune function, cardiovascular disease, memory disorders and cancer. The objective of this study was to evaluate the PKA inhibitory activity of a range of algal extracts, along with their fatty acid composition. Six algal species ...
