Threat to macroalgal diversity: effects of the introduced green alga Caulerpa racemosa in the Mediterranean
Caulerpa racemosa is a tropical green alga introduced into the Mediterranean probably as an immigrant from the Red Sea. This study evaluated the modifications caused by C. racemosa invasion on the structure of the benthic macroalgal community near Leghorn (northwestern Mediterranean). To achieve this objective, we studied invasion by C. racemosa of algal assemblages on 2 different substrata by ...
متن کاملremoval of lead and cadmium ions from aqueous solutions using dried marine green macroalga (caulerpa racemosa)
in this study caulerpa racemosa has been characterized and used for the removal of cd(ii) and pb (ii) from aqueous solutions. the effect of ph, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. langmuir and freundlich models were applied to describe the biosorption isotherm of the metal ions by c. racemosa biomass. the adsorption data can be ...
متن کاملUsing marine mammal habitat modelling to identify priority conservation zones within a marine protected area
One common approach to marine conservation is the designation of marine protected areas (MPAs). Marine mammals have been proposed as a target species for such areas due to their role as indicators of ecosystem processes. In NE Scotland, a large multiple-use MPA has been designated to protect bottlenose dolphins Tursiops truncatus. We used broad-scale surveys throughout this MPA to model habitat...
متن کاملMediterranean Species of Caulerpa Are Polyploid with Smaller Genomes in the Invasive Ones
Caulerpa species are marine green algae, which often act as invasive species with rapid clonal proliferation when growing outside their native biogeographical borders. Despite many publications on the genetics and ecology of Caulerpa species, their life history and ploidy levels are still to be resolved and are the subject of large controversy. While some authors claimed that the thallus found ...
متن کاملAn NADP-dependent Glutamate Dehydrogenase in Chloroplasts from the Marine Green Alga Caulerpa simpliciuscula.
NADP-dependent glutamate dehydrogenase was partially purified from extracts of the marine siphonous green alga Caulerpa simpliciuscula. The enzyme had an apparent Km NH(4) (+) of 0.4 to 0.7 mm and was highly specific for NADPH, alpha-ketoglutarate, and ammonium ions.The bulk of the NADP-glutamate dehydrogenase was isolated with the chloroplast fraction in cell-free preparations of this alga and...
