This paper systematically reviews and synthesizes peer-reviewed, English-language scientific publications (n=212) to identify relevant research about how Ecosystem-. Based Adaptation (EBA) is integrated with coastal planning. Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) methodology is applied in this study. Attention was given to studies concerning human-environment interactions as opposed to physical or biological climate change issues alone because the coastal planning and EBA approach addresses the management of human actions in nature. The literature references include the issue of climate change (77%); however, limited evidence of EBA in coastal areas are reported (18%), and it is evident that the issues have become relevant in the scientific literature published in recent years. Broad texts demonstrate that SLR is one of the major long-term impacts (68%), and all of these papers recognize the most affected ecosystems in the tropics would be mangroves. EBA is an emerging option that can offset anticipated ecosystem losses and improve coastal planning to cope with SLR because it provides benefits beyond climate change stressors. There is a need to synthesize a road map for incorporation of mangrove regulations into local planning instruments and for building capacity for their implementation. Application of PRISMA in marine science will enhance future reviews, facilitate the systematic search and adequately document any theme, and also be useful in determining research gaps or information needs. © 2014 Elsevier Ltd.

During the last decade, knowledge of azooxanthellate corals in the Colombian Caribbean has increased through exploration campaigns by the Marine and Coastal Research Institute (INVEMAR). The distribution of 142 species of corals, including hard corals (Scleractinia 64 species), black corals (Antipatharia 18 species), and soft corals (Octocorallia 60 species) is assessed. Statistical analyses were performed to examine the coral species distribution through a geographic gradient (210 stations in 8 sectors) and a bathymetric range (10-520 m depth). Four principal patterns were observed: (1) northeastern distribution (46 species), (2) southwestern distribution (11 species), (3) association with azooxanthellate coral bioherms (37 species), and (4) widespread (44 species). In addition, 4 species were only found around the San Andres Archipelago (insular pattern). Two main oceanographic factors were identified to play a role in the northeast versus southwest coral fauna separation, La Guajira upwelling system and the Magdalena River influx. These patterns appear to be depth-related, since the separation between northeast and southwest was mainly shown by the shallow-water coral fauna, whereas most of the deep-water corals (>200 m depth) were widely distributed along the Colombian Caribbean coastline. These data were also analyzed from a conservation perspective in order to propose new strategies for the protection of the Colombian Caribbean coral fauna. © 2012 The Author(s). Source

Laccases are multicopper-oxidase enzymes that catalyze one-electron oxidation of phenolic compounds, and other electron-rich substrates with the concomitant reduction of O2 to H2O. One of the most important applications of these enzymes can be found in bioremediation processes, for which the search for enzymes derived from marine organisms can be considered strategic due to the physicochemical characteristics of contaminated effluents. In this study, a comparative molecular docking analysis was made considering the behavior of putative laccases of marine and terrestrial origin against six industrial dyes. Using sequences retrieved from NCBI and Uniprot databases, three-dimensional structures were obtained and validated by computational methods. These models were used for docking studies with the dyes Acid Orange 10, Amido Black, Reactive Blue 4, Reactive Yellow 14, Remazol Black B, and Trypan Blue. The results showed an outstanding behavior of the putative laccase from marine-derived bacteria Pantoea agglomerans, which showed the best affinity interaction with the dyes Amido Black (-8, 2 kcal/mol), Reactive Blue 4 (-9, 4 kcal/mol), and Reactive Yellow 14 (-8, 6 kcal/mol). Likewise, the putative laccase from marine-derived bacteria Bacillus stratosphericus showed the best affinity interaction with the dyes Acid Orange 10 (-7. 5 kcal/mol), and Remazol Black B (-8. 3 kcal/mol). The findings obtained in the present study demonstratethe potential of microbial enzymes that can be found in marine ecosystems, and establish that specific sequences might be used for further construction of synthetic genes in experimental evaluations. © 2016, Sphinx Knowledge House.
