Special Issue Information

Dear Colleagues,

The oceans represent a huge unexplored resource and harbor a tremendous variety of flora and fauna. The marine environment offers a new frontier for research and attracts scientists from different disciplines, such as organic chemistry, bioorganic chemistry, pharmacology, biology and ecology. Although the field of marine natural products is a relatively new area of research, because of the difficulties involved in collecting samples, it has already proven to be a productive source of biologically-active natural products. The development of SCUBA in the 1960s, and more recently submersible vehicles, have allowed easy access to both shallow- and deep-water marine organisms for studies by natural product chemists.

Many marine-derived secondary metabolites are structurally complex with unique functionalities and possess pronounced biological activity. This is due in part to an extreme and harsh living environment, with high ionic concentrations, high pressure, variable temperatures, a lack of light, as well as low nutrient availability. As conditions in the ocean are so markedly distinct, the chemistry produced by its inhabitants is also quite varied. While terrestrial sources of pharmaceuticals and biochemicals have been considerably explored, less than one percent of marine species have been examined for the production of novel chemistry. Thus, the oceans represent a rich and still largely untapped resource for biologically active compounds. In addition, completely unknown biochemical pathways in pathogens or disease may be discovered and targeted by such unique chemotypes, leading to the development of novel therapeutics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Biodiversity is undergoing rapid and worrying changes, partially driven by anthropogenic activities. Human impacts and climate change (e.g., increasing temperature and ocean acidification), which act at different spatial scales, represent the most serious threats to biodiversity and ecosystem structure and function. In the Mediterranean Sea, complex systems such as fucoid algae and seagrasses, characterized by a high associated biodiversity, are regularly exposed to natural and anthropogenic pressures. These systems, particularly sensitive to a variety of stressors, evolved several physiological and biochemical traits as a response to the different pressures which they are subjected to. For instance, they produce a huge quantity of secondary metabolites such as phenolic compounds, to adapt to different environmental stressors and to defend themselves from biological pressures. These natural products are receiving increasing attention due to their possible applications in a wide range of industrial sectors. In this paper we provide an overview on the ecological role of phenolic compounds from the genus Cystoseira sensu lato and Posidonia oceanica (L.) Delile, also highlighting their potential use as ecological biomarkers. Full article
