Special Issue Information

Dear Colleagues,

The global discussion regarding climate changes in recent years has resulted in increased interest in seagrasses meadows in a holistic manner in scientific and socio-political contexts.

Seagrasses are marine flowering plants, adapted to live underwater and where there is very limited light; despite this fact, they are able to photosynthesize. In plant fields, the great developments of cutting-edge technical methodologies (proteomics, genomics, metabolomics, in general omics, and molecular approaches) and data analyses has driven discoveries in plant physiology and the comprehension of different biological mechanisms to counteract and find solutions to deal with the climate emergency. Although there have been many advancements in terrestrial plants, research regarding seagrass has been less fast-growing; the seagrass ecological role remains undiscussed despite its importance for ecosystems. The role of seagrass is to be a marker for the detrimental effects of the anthropological activities, to create healthy habits for biodiversity, and to play a role in the carbon sequestration capacity. Additionally, for these reasons, the first sequenced seagrass species almost a decade ago was a milestone in the seagrass biology. In recent years, climate change events have become clearer and the worldwide detrimental effects are becoming increasingly obvious.

The Special Issue will focus on the scientific advances regarding the knowledge of seagrass meadows and how a better understanding of their safeguard has the potential to help in the worldwide climate crises. We are also looking to provide a deep understanding of the biological processes that seagrasses have put in place to adapt to such an inhospitable environment, such as the sea depth, and to improve these processes.

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. Plants 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 2700 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.

Brown algae from genus Cystoseira s.l. form dense underwater forests that represent the most productive areas in the Mediterranean Sea. Due to the combined effects of global and local stressors such as climate change, urbanization, and herbivore outbreaks, there has been a severe decline in brown algal forests in the Mediterranean Sea. Natural recovery of depleted sites is unlikely due to the low dispersal capacity of these species, and efficient techniques to restore such habitats are needed. In this context, the aims of our study were (1) to improve and simplify the current ex situ laboratory protocol for the cultivation of Gongolaria barbata by testing the feasibility of some cost-effective and time-efficient techniques on two donor sites of G. barbata and (2) to evaluate the survival and growth of young thalli during the laboratory phase and during the most critical five months after out-planting. Specifically, the following ex situ cultivation methods were tested: (A) cultivation on clay tiles in mesocosms with culture water prepared by three different procedures (a) filtered seawater with a 0.22 μm filter membrane, (b) filtered seawater with a 0.7 μm filter membrane (GF), and (c) UV-sterilized water, and (B) cultivation on clay tiles in open laboratory systems. After two weeks, all thalli were fixed to plastic lantern net baskets suspended at a depth of 2 m in the coastal sea (hybrid method), and the algal success was monitored in relation to the different donor sites and cultivation protocol. The satisfactory results of this study indicate that UV-sterilized water is suitable for the cultivation of G. barbata in mesocosm, which significantly reduces the cost of the laboratory phase. This opens the possibility of numerous and frequent algal cultures during the reproductive period of the species. Additionally, if the young thalli remain in the lantern net baskets for an extended period of several months, they can grow significantly in the marine environment without being exposed to pressure from herbivorous fish.
