Human-Induced Problems (Uses and Abuses)

[Extract] This volume focuses on the human activities in estuaries and on coasts and the spatial and temporal conflicts between them. It covers estuaries (transitional water bodies) and coasts as well as areas of coastal influence. It examines the sources of the problems and assesses the causes and consequences of change.\ud \ud It becomes apparent that we are increasingly emphasizing to stakeholders and policymakers the need to consider the ability of the estuarine and marine environment to deliver a set of fundamental ecosystem services leading to societal benefits. We show in particular the need for a multidisciplinary approach linking natural and social sciences, especially the ability to protect ecosystem services and to deliver societal benefits

Isolation and characterization of Pseudoalteromonas strains with divergent polycyclic aromatic hydrocarbon catabolic properties

Fifteen strains of polycyclic aromatic hydrocarbon (PAH)-catabolizing bacteria, identified as Pseudoalteromonas spp. were isolated from Eagle Harbor, Puget Sound, USA, using a most probable number procedure in which naphthalene or phenanthrene was the sole carbon and energy source. Despite having identical 16S rDNA sequences, some catabolized many PAHs, whereas others oxidized only naphthalenes. A putative naphthalene 1,2-dioxygenase gene fragment was polymerase chain reaction-amplified from the naphthalene-degrading strains and shown to be almost identical to a gene present in Neptunomonas naphthovorans, suggesting horizontal transfer
