The wetlands of Sardinia (Italy) supply food and shelter for many waterbird species that migrate along the central–eastern Mediterranean bird flyway. Despite different policies laws (the Birds Habitats Directives, European Water Framework Directive, Ramsar Convention), Sardinian are seriously threatened by human activities climate change, which in turn menace associated avifauna.

Water mint (Mentha aquatica) is used in many formulations worldwide as a functional food and natural remedy to treat gastrointestinal disorders, lung diseases, certain mental disorders such epilepsy depression. This study assessed the bioactivity of its infusion extract (INF) hydroethanolic (HE) highlight health benefits. These extracts were analyzed for their chemical composition by HPLC-DAD-ESI-MSn, antioxidant antidiabetic properties, capacities protect human erythrocytes against induced hemoglobin oxidation lipid peroxidation. The effect on normal dermal fibroblast (NHDF) cells N27 rat dopaminergic neuron cell line was also assessed. chromatographic analysis identified 57 compounds belonging hydroxycinnamic acids, flavanones, flavone, isoflavonoids. In respect biological potential, Mentha aquatica revealed notable capacity 2,2-diphenyl-1-picrylhydrazyl, nitric oxide, superoxide radicals, well inhibition α-glucosidase action protection oxidative damage. Quantification noteworthy phenolic content both extracts. Additionally, demonstrated less cytotoxic effects regarding NHDF lines. Overall, presents promising activity spectrum potential activities, underscoring significance novel candidate applications animal nutrition, medicine, product research pharmaceutical nutraceutical industries.

The Sicilian wetlands (Italy) are seriously threatened by human activities and ongoing climate change. loss of these as migratory stepping stones could severely hamper the flow many bird species along central Mediterranean. Targeted actions for conservation avifauna require thorough knowledge utilization that waterbirds make habitats. Aiming to inform planning more satisfactory habitat management diversity preservation Mediterranean flyway, in this study, we inventoried avian metacommunity coastal Sicily during most critical period year (July–September) used a multilevel analytical framework explore spatiotemporal dynamics assemblages. We recorded 73 species, which almost 90% were 30 belonged Annex I Birds Directive. At level, found all biodiversity metrics low July approximately doubled successive sampling sessions (August–September), where they showed little if any community detected two main clusters with regard richness, one (wetlands Baronello, Gela, Gornalunga, Roveto) was characterized higher levels richness nearly dates. pattern similar between first second half August, while very dissimilar from other guild significant increase July–September number belonging “Mediterranean” migration “divers surface” “surface feeders” foraging guilds. temporal sequence occurrence waterbird species: only early dwellers July, ten late September, twenty-six made use summer long. spatial distribution differed significantly pair Overall, Little Grebe, Spotted Redshank, Tern highest site infidelity; contrast, Black Stork, Broad-billed Sandpiper, European Golden Plover, Common Shelduck, Black-necked Grebe changed their among least July–September. Our study allowed us detect (1) (2) priority should be assigned, well (3) exact time span when measures mandatory, not advisable. These results provide broader insight space–time patterns assembly period.

Climate patterns in North Africa, specifically the southern Mediterranean, have changed considerably due to global climate change. As a result, major environmental problem has emerged: deterioration of wetlands and associated ecosystems, which are protected under Ramsar Convention. This study examines state an artificial wetland, notably reservoir formed by Ain Zada Dam northeastern Algeria, from 2001 2021. RS, GIS, GEE were used analyse indices satellite images. The found that reservoir’s water storage decreased significantly, 10.5 million m 3 2.4 finding is entirely consistent with NDWI index, was generated analysis 151 drop had extensive effect on ecosystem. That decline linked changes region’s environment over last 40 years, been characterized lower levels higher temperatures, providing additional evidence warming.
