Article Abstract
Mercury contents were determined in surface sediments from the Central and Southern Adriatic Sea to gain insight into the processes, factors, and variables affecting its distribution. Mercury concentration was measured by thermal decomposition amalgamation atomic absorption spectrometry in samples collected by box-corer from Ancona to Santa Maria di Leuca during the CNR-PERTRE cruise (16/9-4/10/2016). Sediments were also evaluated for chemical-physical parameters (pH, Eh), biogeochemical composition (total carbon, inorganic carbon, total organic carbon, organic matter) and grain size. The average mercury concentration in the Adriatic Sea sediment was 0.053 mg/Kg (d.w.), range 0.011-0.12 mg/Kg (d.w.). Mercury content was mainly affected by grain size and organic matter (OM) distribution, whereas anthropic factors exerted a limited influence. Concentrations followed the distribution of sediment types (clay > silt > sand) due to Adriatic Sea hydrodynamics and were well below the regulatory limits in all samples.

Mercury (Hg) contamination in marine species is a critical environmental and public health issue, particularly for commercially important resources like mantis shrimp, Squilla mantis. This study assessed Hg levels in muscle and gonadal tissues of 64 female S. mantis from the Adriatic Sea, assessed into pre-spawning, spawning, and post-spawning reproductive stages.

The Atlantic blue crab (Callinectes sapidus Rathbun, 1896) is a euryhaline and eurythermal species native to the Atlantic coasts of the Americas. Although its widespread distribution across the Mediterranean basin is well documented, information on its reproductive patterns remains limited. This study focused on the combination of both macroscopic and histologic characterization of ovarian developmental stages in female blue crabs along the north-central Italian Adriatic coast, within the spawning period.

Among-individual variability in animal behaviour and diet leads to a plethora of mini-niches within a population's general niche. Such variability is directly or indirectly linked to inter- and intra-specific competition, behavioural adaptation and variation in foraging tactics, which may lead to evolutionary divergence and speciation but is also relevant to population resilience and conservation. We used boat surveys, photo-identification techniques, biopsy sampling and stable isotope analysis (δC, δN) to study the intra-population isotopic niche variation in an apex predator, the common bottlenose dolphin (Tursiops truncatus), in the northern Adriatic Sea.

Knowledge about the composition (volatile and non-volatile) and functionality of natural extracts from Mediterranean plants serves as a basis for their further application. In this study, five selected plants were used for the extraction of plant metabolites. Leaves and flowers of , , , and were collected, and a total of 12 extracts were prepared.

The opportunistic diet of loggerhead sea turtles, Caretta caretta, their long life-span and migratory behavior contribute to shaping the diversity of the gastrointestinal helminthic community. Heteroxenous helminths are also sentinels of marine environmental health, reflecting any perturbation of the trophic chain and, indirectly, of abiotic components of the ecosystem. With the aim of studying the helminth community of a top predator such as the loggerhead sea turtle C.
