Effect of chitosan-based surfaces on biofilms formed by Cobetia marina

The characterization (roughness and water contact angle) of poly (lactic acid) surfaces coated with chitosan of different molecular weights and concentrations obtained from the Loligo opalescens pen was performed. The antifouling activity of these surfaces against Cobetia marina biofilm formation was evaluated, as well as the mechanism of action of this type of chitosan.

Riassunto visuale del progetto "BIOMARCS - Riannodiamo la biodiversità marina"

Questo riassunto visuale, disegnato da Jacopo Sacquegno, riassume l'iniziativa di citizen science, o scienza partecipativa "Riannodiamo la biodiversità marina" (Titolo esteso: Integrating biodiversity monitoring and awareness-raising in coastal peripheries, by engaging citizen-science sailors as focal nodes in the process of local community empowerment; acronimo: BIOMARCS; nome alternativo: Reknotting Marine Biodiversity), finanziata dal progetto europeo IMPETUS* (<a href="https://impetus4cs.eu/">https://impetus4cs.eu/</a>; Grant agreement ID: 101058677; DOI: 10.3030/101058677) L'iniziativa coinvolge i velisti delle aree costiere periferiche nella co-progettazione, creazione e gestione di un monitoraggio opportunistico dell'ecosistema marino e della sua biodiversità attraverso tecniche di analisi del DNA ambientale (eDNA). Gli stessi velisti contribuiscono a diffondere e comunicare i dati acquisiti sulla biodiversità tra più parti interessate (ad esempio, studenti delle scuole superiori e gestori di AMP), per rendere "visibile" il patrimonio di biodiversità e rafforzare il senso del luogo e la consapevolezza dell'importanza della salute degli oceani per il benessere delle società umane.*IMPETUS is funded by the European Union's Horizon Europe research and innovation programme under grant agreement number 101058677.

Future Projections for Posidonia oceanica and Zostera marina in Europe

Future projections of seagrass biomass for Posidonia oceanica and Zostera marina in Europe. Supporting data for T4.1 of Horizon 2020 project FutureMARES. The file naming convention is {species}_{cmip6_model}_{ssp}, where species identifies whether the model run is for P. oceanica or Z. marina, cmip6_model names the CMIP6 model uses to drive the projections, and ssp identifies which of SSP126, SSP245 and SSP585 were used. Projections cover the year 1995-2099.

Isotopes and content of carbon, nitrogen, and sulfur of eelgrass (Zostera marina) from West Falmouth Harbor from 2005 through 2019

West Falmouth Harbor (West Falmouth, MA, USA) has been experiencing a dramatic increase in nitrogen loading from an upgradient municipal wastewater treatment facility since the early 2000’s. As part of a long-term study into the effects of this nitrogen enrichment, we have been assessing changes in the extent and health of the eelgrass (Zostera marina) community within the harbor. Eelgrass shoots were collected during the summer and run for carbon (C), nitrogen (N), and sulfur (S) content and isotopic composition. Samples were analyzed from 7 stations in the more well-flushed outer harbor (OH), 4 stations in the middle of the harbor (MH), and 6 stations in the inner portion of the harbor in close proximity to a high groundwater nitrate source (Snug Harbor, SH). Carbon data is available from 2011 through 2018, nitrogen data from 2006 through 2018, and sulfur data from 2005 through 2019 with a few samples from 2021. Sulfur results have been published in Haviland et al. 2022 (doi: 10.1002/lno.12025).

Rapid diversification of gray mangroves (Avicennia marina) driven by geographic isolation and extreme environmental conditions in the Arabian Peninsula

Biological systems occurring in ecologically heterogeneous and spatially discontinuous habitats provide an ideal opportunity to investigate the relative roles of neutral and selective factors in driving lineage diversification. The gray mangroves (Avicennia marina) of Arabia occur at the northern edge of the species' range and are subject to variable, often extreme, environmental conditions, as well as to historic large fluctuations in habitat availability and connectivity resulting from Quaternary glacial cycles. Here, we analyze fully sequenced genomes sampled from 20 locations across the Red Sea, the Arabian Sea, and the Persian/Arabian Gulf (PAG) to reconstruct the evolutionary history of the species in the region and to identify adaptive mechanisms of lineage diversification. Population structure and phylogenetic analyses revealed marked genetic structure and highly supported clades among and within the seas surrounding the Arabian Peninsula. Demographic modeling showed times of divergence consistent with recent periods of geographic isolation and low marine connectivity during glaciations, revealing the presence of (cryptic) glacial refugia in the Red Sea and the PAG. Significant migration was detected within the Red Sea and the PAG, and across the Strait of Hormuz to the Arabian Sea, suggesting gene flow upon secondary contact among Arabian mangrove populations. Genetic‐environment association analyses revealed high levels of adaptive divergence and detected signs of multi-loci local adaptation driven by temperature extremes and hypersalinity. These results support a process of rapid diversification resulting from the combined effects of historical factors and ecological selection and reveal mangrove peripheral environments as relevant drivers of lineage diversity.

Sex-based differences in the use of post-fire habitats by invasive cane toads (Rhinella marina)

Wildfires can modify habitat attributes, and those changes may differentially affect males versus females within a species if there is pre-existing niche divergence between the sexes. We used radio-tracking and dissections to study invasive cane toads (Rhinella marina), and performed transect counts on native frogs and cane toads 12 months after extensive fires in forests of eastern Australia. Both toads and native frogs were encountered more frequently in burned sites than in unburned sites. Most microhabitat features were similar between burned versus unburned areas, but fire had differential impacts on the ecology of male versus female toads. In burned areas females were less numerous but were larger, in better body condition, and had consumed more prey (especially, coleopterans and myriapods). The impact of fire on attributes of retreat-sites (e.g., temperature, density of vegetation cover) also differed between the sexes. More generally, intraspecific divergence in ecological traits within a species (as a function of body size as well as sex) may translate into substantial divergences in the impacts of habitat change.
