Special Issue Information

Dear Colleagues,

Shallow- and deep-water marine biotic communities in the world’s oceans are subject to profound changes owing to ongoing climate changes, overfishing, species introductions, pollution, and habitat destruction. Although the magnitude of these factors varies in time and space, recent studies indicate profound irreversible changes in marine biotic communities. Climate change, directly and indirectly, affects marine species populations and communities,  thereby affecting the structure and functioning of ecosystems, magnifying the impacts of other anthropogenic changes. Overfishing causes biomass declines in several species populations and alters their population structure, such as size at maturity. The habitats of the world’s oceans are under siege by alien invasive species, causing adverse, irreversible consequences for the native biodiversity, ecosystem services, economy, and human health. Climate change, increasing ship carrying capacities and speeds, the widening and deepening of man-made canals, and pollution favor the introduction of these species and their successful establishment. Pollution from diverse sources leads to direct species mortality as well as changing the state of the community from a highly diversified level to an impoverished species level. Habitat destruction is a major threat to the structure and functioning of marine biotic communities, exacerbating overfishing by limiting fishable areas or decreasing the productivity of marine environments. In this context, long-term monitoring studies have become critical to assess the dimension of these factors and to prepare effective management plans to cope with these challenging issues.

The topic focuses on marine biotic changes as a consequence of anthropogenic activities from any geographic region. Papers may include issues related to biotic changes and the monitoring of species and communities.

We are interested in the following research areas:

Community shifts;

Alien species;

Monitoring of marine species and communities;

Habitat mapping;

Ecological Quality Status.

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. Sustainability 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 2400 CHF (Swiss Francs).

The Predation of Pinna nobilis (Mollusca) Juveniles by the Spiny Sea Star Marthasterias glacialis (Echinodermata) in the Sea of Marmara

The critically endangered bivalve species, the pen shell Pinna nobilis, has been suffering from an epidemic disease in the Mediterranean Sea, and its populations have totally disappeared in many areas across the basin. The Sea of Marmara’s populations of the pen shell, which were previously assumed to have remained unaffected by the epidemic disease because of the special hydrographical condition of the sea (brackish water), have been devastated after the catastrophic mucilage event suddenly outburst in November 2020 in the region. The settlement of healthy juvenile specimens of the species was frequently observed in the area after the mucilage event. However, an unexpected predator of juvenile specimens of the pen shell, the spiny sea star Marthasterias glacialis, was encountered in the area in January 2023. Two cases were observed and the spiny sea star has a capability of crashing one valve of the sea-pen through which it consumes its flesh. This predation might have the potential to affect populations of P. nobilis, which has been struggling to survive in the region after its mass mortality due to the mucilage event. Such data are of utmost importance to imply effective conservation planning for the sustainability of the remaining populations of the pen shell in the region. Full article

The first cave-monitoring studies to be carried out on the southwest (SW) coast of Türkiye on endangered Mediterranean monk seals using camera traps occurred between 2017 and 2021 in five marine caves within Gökova Bay. The visual data obtained from the monitoring studies were evaluated to reveal the Mediterranean monk seals’ seasonal and diel cave use and identify the individual seals who were using the caves. Moreover, the necessary features and measurements of the identified caves were recorded to determine whether there were any correlations between the determined variables and monthly cave use by the monk seals. The results showed that cave use occurred mainly nocturnally, with the seals showing a diurnal activity pattern in the area. We evaluated 108,280 images/videos in total and identified 18 individuals using five caves in Gökova Bay. Three of these caves provided suitable characteristics for pupping, and two of them were used for pupping. A beta regression model revealed that the monthly cave use ratios varied seasonally, with more use in the fall season. Furthermore, the trends in annual cave use ratios, seasonality, wind speed, size of the wet area, luminance, number of cave-entry paths, and human activity were the best variables with which we could forecast the cave preferences of the seals.
