TL;DR: In this article, a review of current functioning and responses of Mediterranean marine biogeochemical cycles and ecosystems with respect to key natural and anthropogenic drivers and to consider the ecosystems' responses to likely changes in physical, chemical and socio-economical forcings induced by global change and by growing anthropogenic pressure at the regional scale.

TL;DR: The recent development of techniques such as solid-phase cytometry, the increasing sensitivity of fluorescence tools and multiparametric approaches combining taxonomic and physiological probes have improved the effectiveness of direct methods in environmental and industrial microbiology.

TL;DR: It is suggested that nucleic acid content alone can be a better indicator of the fraction of growing cells than total counts and that this approach should be combined with other fluorescent physiological probes to improve detection of the most active cells in aquatic systems.

TL;DR: The results revealed that there are wide variations in marine bacteria in their responses to UV radiation and subsequent repair strategies, suggesting that UV-B radiation may affect the microbial community structure in surface water.

TL;DR: The bacterial populations inhabiting the sea surface microlayer from two contrasted Mediterranean coastal stations were examined by culturing and genetic fingerprinting methods and were compared with those of underlying waters, suggesting that the sea-surface layer is a poorly understood microbial environment and may represent a natural source of new microorganisms.
