Special Issue Information

Dear Colleagues,

Nearshore ecosystems contain most of the ocean’s highly productive waters and varied habitats that support a range of phyla more diverse than that which terrestrial ecosystems hold. This band of water spanning continents and islands extends seaward from the intertidal zone out through the subtidal to a depth of 90 meters and envelops most of the marine biodiversity hotspots. The valuable services provided by nearshore ecosystems are as diverse as their plant and animal inhabitants. Among the marine ecosystems, nearshore biodiversity has the deepest history of exploration, exploitation, and benefits to society. Yet, as coastal sea water temperatures, sea levels, sea water chemistries, and coastal currents change, the populations of the nearshore benthos are reduced, restructured, and replaced. These consequences are understood through the altered phenology of life histories, changed abundance and genetic diversity, species range shifts, and modified ecosystem functions.

This Special Issue will highlight recent advances in research on nearshore biodiversity, covering its relationship with biogeography, coastal oceanographic processes, ecosystem functions, species introductions and range shifts, community ecology and genetics. Research concerned with the interactions of commercial harvesting, aquaculture and pollution with nearshore biodiversity is also invited. In summary, this collection aims to present, in a broad sense, a global comparison of nearshore biodiversity and the drivers of change.

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. Diversity 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.

The Marine Protected Area (MPA) Namuncurá−Burdwood Bank was created in 2013 to protect the benthic community. After five years of multidisciplinary research, it was reorganized, and a second, contiguous MPA Namuncurá−Burdwood Bank II was created. The objectives of this study were to evaluate the decapod assemblages in both the previous and current management zones and to compare them with the neighboring areas of southern South America. The decapod fauna was studied integratively by comparing captured species onboard scientific expeditions with online records. Our study showed that the original design of the MPAN−BB had the lowest decapod species richness. However, the constitution of a larger protected area, including the slope, increased the species richness, with unique records of Campylonotus arntzianus and Lithodes couesi. The MPA could be considered ecologically representative as it shares various species with the nearby areas (the Beagle Channel and the Atlantic). Furthermore, we theorize it could act as a “hub” for decapod species as marine currents provide the Burdwood Bank with new individuals from the west and disperse them northward to the Patagonian Shelf and eastward to the Scotia Arc. This result shows the great value of protecting this area, ensuring the conservation of the decapod fauna of southern South America. Full article
