Seed dormancy and germination niches of Mediterranean species along an altitudinal gradient in Sardinia
… dormancy has probably evolved differently across species, through adaptation to various habitats and prevailing environments. Under a Mediterranean climate, characterised by a considerable unpredictability of temperature and precipitation, with hot dry summers and cold wet winters, the plant …

A Question of Luxury: Trading Animals and Animal Parts Across the Indian Ocean
… from the early Roman imperial period. Multiple species are noted to have crossed as part of trade networks and there is evidence that volumes of goods such as ivory, tortoise shell, and red coral were both available and shipped in large volumes from a variety of ports. Though there is limited …

Studio citogenetico della famiglia Muraenidae (Anguilliformes: Actinopterygii) mediante tecniche di citogenetica classica e molecolare
… colour pattern; however the classification of species and genera is still controversial. Comparative cytogenetic, allowing the study of karyotype evolution among species and genera, could contribute to shed light on taxomomic and phylogenetic incertainties on Muraenidae family. Till now, less …

From brain development to reproductive axis: an integrated study of the nervous system in cartilaginous fish
… data on postnatal brain development in Mediterranean chondrichthyans; (ii) the limited availability of comparative neuroecological analyses testing habitat-related brain organization within the Mediterranean Sea; and (iii) the poor understanding of interactions between dopaminergic and …

Evolution of the genus Aristolochia (Aristolochiaceae) in the Eastern Mediterranean including the Near East and Caucasia
… sensu lato comprise between 450 and 600 species, distributed throughout the world with centers of diversities in the tropical and subtropical regions (Neinhuis et al., 2005, Wanke et al., 2006a, 2007). However, the extended Mediterranean region including Turkey, the Caucasus and the Near …

Seed germination requirements and salt stress tolerance of coastal rare species in Sardinia
… that characterize coastal environments, plant species often require special physiological or metabolic adaptations to overcome environmental stresses. Stress may be physical (e.g. temperature) or chemical (e.g. salinity). Many communities comprise highly specialized species, which have …

Evolution of the genus Aristolochia - Systematics, Molecular Evolution and Ecology
… worldwide distribution. The order includes three species rich genera, Piper (ca. 1,000 species), Peperomia (ca. 1,500-1,700 species), and Aristolochia s. l. (ca. 500 species). Sequences of the matK gene and the non-coding trnK group II intron are analysed for a dense set of 105 taxa representing …

DEVELOPMENT OF LEGUME-DERIVED INGREDIENTS AND FOODS ENRICHED IN BIOACTIVE COMPOUNDS USING DIFFERENT STRATEGIES
… 33 ecotypes, plus 5 controls belonging to the Mediterranean species, to assess free phenolic compounds and explore the potential of FT-NIR for evaluating antioxidant properties. Additionally, an optimized debittering method was proposed and compared with traditional ones for impact on residual …

COLLAGEN AND ANTIOXIDANTS FROM SEA URCHINS: WASTE VALORIZATION CHALLENGES TOWARDS REGENERATIVE MEDICINE
… was to investigate the potential of different species that make up the global waste stream as sources of antioxidants and collagen, in order to increase the potential of the “sea urchin circular supply chain” by exploiting waste other than P. lividus. Therefore, a comparative study on the …

Plasticity, Intraspecific Variability and Local Adaptation to Climatic Extreme Events of Ecotypes/Provenances of Key Plant Species
… changes is likely to occur at a pace, which species may not be able to keep track with by natural dispersal or genetic adaptation. Agriculture, forestry and ecosystem management must develop counteracting practices to secure the persistence and functioning of these ecosystems and thus their …
