Special Issue Information

Dear Colleagues,

The tendency toward climate change has been one of the most surprising outcomes of the study of Earth history. Over the last decades, considerable interest has arisen in the role of the subtropical oceans in climate change and, in particular, oceanic sub-basins and marginal seas, which are often more responsive to paleoceanographic and paleoclimatic changes than the global oceans because of their smaller size and partial isolation. As an example, the small volume of the Mediterranean Sea, compared with ocean basins, causes changes in its climate that can be recorded virtually instantaneously in palaeoceanographic and sedimentological proxy data, such as stable isotopes and geochemical ratios, as well as microfossil abundances. Marine geological dynamics, such as sea-level changes, environmental parameters, sedimentary cyclicity, and climate are strongly related through a direct exchange between the oceanographic and atmospheric systems. Moreover, anthropogenic activities affect the natural evolution by changing both the seawater environmental parameters and the ratio between terrigenous and marine sediments, which is further reflected in the marine biota.

This Special Issue aims to provide an overview of the interplay of all these processes across a variety of settings (coastal to open marine) and timescales (early Cenozoic to modern). Among the priorities are the hydroclimate reconstructions using integrated geochemical and/or paleontological proxies measured from different Mediterranean sub-basins. We also encourage contributions outlining the applications of novel state-of-the-art techniques that provide important information on this topic.

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 papers will be 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. Water is an international peer-reviewed open access semimonthly 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 2000 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.

Integrated otolith chemistry and muscle tissue stable isotope analyses were performed to allocate juvenile Diplodus puntazzo and Diplodus vulgaris to nurseries in the Adriatic Sea. Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) was used to quantify the concentrations of chemical elements in the otoliths. Fish muscle samples were analysed for δ13C and δ15N. In general, Ba/Ca and Sr/Ca ratios and isotopes varied between sites and species. Values of δ13C and δ15N were significantly different between species and sites. Multivariate analysis detected a significant difference in the element signature between species while there was no evidence for a significant interaction for sites. A clear pattern across the four groups of interest, D. puntazzo_Estuary > D. vulgaris_Estuary > D. puntazzo_Coastal > D. vulgaris_Coastal, following decreases in δ13C, and increases in δ15N were found. It seems that these species are feeding on the same local food web within more productive estuarine site while at costal site, feeding segregation among investigated species is evident. Both species were re-allocated correctly to the estuarine waters based on the otolith chemistry and stable isotopes information and higher value of δ15N. Combining otolith chemistry with tissue isotope ratios of juvenile fish provided complementary information on nursery habitat use at different spatial scales and elucidated ecological and environmental linkages.
