PMA E BIOLOGIA FORENSE IN AUSILIO DEL PUBBLICO MINISTERO Carra E., Di Natale M.V. Dipartimento di Scienze Tecnologie Molecolari Biomolecolari (STEMBIO)– Università di Palermo Edifio 16, viale delle Scienze.– elena.carra@unipa.it Nell’ambito di attività svolta su incarico dell’Autorità Giudiziaria si è proceduto all’inventario del contenuto di fusti per la crioconservazione di gameti ed embrioni sottoposti a sequestro e custoditi presso i locali di quattro centri di biologia della riproduzione per “verificarne la rispondenza alle registrazioni cartacee ed informatiche acquisite agli atti”. Si rendeva, altresì, necessaria analisi genetica su materiale biologico, costituito da embrione umano d…
Impacts of weathered microplastics on bioavailability of pollutants in Paracentrotus lividus and Danio rerio: molecular and ecotoxicological approaches
Plastic materials provide countless applications in every sector of human life, from food and health preservation to textiles and electronics industry (Cole et al., 2011;Thompson et al., 2009) which is resulting in huge amount of plastic waste. Recently, it was estimated that plastics account for the 80-90% of the whole marine litter (Derraik, 2002) and over 5 trillion microscopic plastic fragments are floating on the surface of the World Oceans (Eriksen et al., 2014). The predominant form of marine plastic litter is called “Microplastics (MPs)", terminology by Thompson et al. 2004, used to indicate small plastic fragments, fibers and granules of microscopic size (1 μm to 5 mm in diameter).…
Coupling Lagrangian simulation models and remote sensing to explore the environmental effect on larval growth rate: The Mediterranean case study of round sardinella (Sardinella aurita) early life stages
The relationship between environmental conditions and early life-history traits of Sardinella aurita are investigated using material collected in two sites of the Central Mediterranean Sea. Individual mean daily growth during the planktonic phase has been determined by using otolith microstructure analysis, while Lagrangian simulation models allowed to estimate the daily position in space and time of each specimen from the hatching to the catch. Generalized Additive Mixed Models (GAMMs) have been implemented to explore the impact of environmental conditions at time t, t-1 day and t-2 days on the mean daily growth rate occurring at time t. Spatial analysis evidenced a wide dispersion of eggs…
Environmental Conditions along Tuna Larval Dispersion: Insights on the Spawning Habitat and Impact on Their Development Stages
Estimated larval backward trajectories of three Tuna species, namely, Atlantic Bluefin Tuna (Thunnus thynnus, Linnaeus, 1758), Bullet Tuna (Auxis Rochei, Risso, 1801) and Albacore Tuna (Thunnus alalunga, Bonnaterre, 1788) in the central Mediterranean Sea, were used to characterize their spawning habitats, and to assess the impact of changes due to the major environmental parameters (i.e., sea surface temperature and chlorophyll-a concentration) on larval development during their advection by surface currents. We assumed that the environmental variability experienced by larvae along their paths may have influenced their development, also affecting their survival. Our results showed that the …
