A new rare species of Oedipoda Latreille, 1829 (Orthoptera: Acrididae) from South Italy
2019
Oedipoda cynthiae n. sp. (Orthoptera: Acrididae: Oedipodinae) is described from Apulia (South Italy). In the past, the same population here considered had been assigned to O. miniata and later to O. charpentieri. Morphological features, biogeographical considerations, and a preliminary molecular analysis confirm that this population must be assigned to a new species, which is described and illustrated here.

Heat requirements for loquat fruit development may be assessed with a Beta model approach
2018
In Mediterranean areas, loquat trees (Eriobotrya japonica Lindl.) typically bloom in fall and fruits develop during the winter period, reaching their ripening in spring. So far, little interest has been driven towards models capable of estimating heat requirements for the accomplishment of fruit development in the winter period. In this work, we verified whether in Mediterranean areas the heat accumulation (GDH) needed for loquat fruit growth, may be precisely described using a Beta model, a flexible mathematical function which, in the past, has been successfully used in peach. BBCH phenological stages of ‘Algerie’ trees were recorded in two experimental sites: Palermo, Italy (38°04’N, 13°2…
Use of Lagrangian simulations to hindcast the geographical position of propagule release zones in a Mediterranean coastal fish
2018
International audience; The study of organism dispersal is fundamental for elucidating patterns of connectivity between populations, thus crucial for the design of effective protection and management strategies. This is especially challenging in the case of coastal fish, for which information on egg release zones (i.e. spawning grounds) is often lacking. Here we assessed the putative location of egg release zones of the saddled sea bream (Oblada melanura) along the southeastern coast of Spain in 2013. To this aim, we hindcasted propagule (egg and larva) dispersal using Lagrangian simulations, fed with species-specific information on early life history traits (ELTs), with two approaches: 1) …
Typification of the Mediterranean Endemic Deep-Water MacroalgaLaminaria rodrigueziiBornet (Laminariaceae, Phaeophyceae)
2016
Abstract Laminaria rodriguezii Bornet is a deep-water brown alga endemic of the Mediterranean Sea. Lectotypification of Laminaria rodiguezii has been based on both Bornet's protologue and the original material housed at the cryptogamic collections of the Museum National d'Histoire Naturelle de Paris (PC).
Propagule dispersal and larval patch cohesiveness in a Mediterranean coastal fish
2016
The assessment of fish dispersal is fundamental for both conservation and management of fishery resources as it provides crucial information for the establishment of more effective marine protected areas (MPAs) and networks of MPAs. In this study, we investigated the elemental composition of otoliths in early life stages of the saddled sea bream Oblada melanura (Linnaeus, 1758) (Perciformes: Sparidae) in order to obtain information on its propagule (egg and larva) dispersal in the south-western Mediterranean Sea. Specifically, using pre-settlement individuals we investigated (1) larval patch cohesiveness during the last phase of larval life; and with early post-settlement individuals we inv…
Epibiotic barnacles of sea turtles as indicators of habitat use and fishery interactions: An analysis of juvenile loggerhead sea turtles, Caretta car…
2019
Abstract Sea turtles exploit a variety of habitats during their lifetime and are thus exposed to a number of anthropogenic threats, including interaction with fisheries. Mitigating this impact requires determining patterns of habitat use by turtles, which largely relies on data from marked individuals. We investigated the use of epibiotic barnacles as a cost-effective method to ascertain habitat use by sea turtles, choosing the juvenile loggerhead sea turtles (Caretta caretta) in the western Mediterranean as a model. A total of 200 turtles collected in the central Spanish Mediterranean between 1990 and 2017 were examined for epibionts: 25% were accidentally captured by pelagic longliners, 1…
Mediterranean monk seal hunting in the regional Epipalaeolithic of Southern Iberia. A study of the Nerja Cave site (Málaga, Spain)
2019
Abstract During the Late Glacial–Early Holocene transition Southern Iberia has an extensive record of Palaeolithic coastal sites, wich have been preserved due thanks to the morphology of the continental shelf. This is was a period with rapid palaeoclimatic oscillations and changes in sea level. However, the sites show an apparent continuity in technology and subsistence trends, although human groups made increasingly intense use of marine resources. In this paper we will focus on the study of Mediterranean seal remains from the Vestibulo hall of Cueva de Nerja (Malaga, Spain), unit NV4, dated 12,990–11,360 cal. BP. The presence of these bones at the site are interpreted as direct exploitati…

Seascape connectivity of European anchovy in the Central Mediterranean Sea revealed by weighted Lagrangian backtracking and bio-energetic modelling
2020
AbstractEcological connectivity is one of the most important processes that shape marine populations and ecosystems, determining their distribution, persistence, and productivity. Here we use the synergy of Lagrangian back-trajectories, otolith-derived ages of larvae, and satellite-based chlorophyll-a to identify spawning areas of European anchovy from ichthyoplanktonic data, collected in the Strait of Sicily (Central Mediterranean Sea), i.e., the crucial channel in between the European and African continents. We obtain new evidence of ecosystem connectivity between North Africa and recruitment regions off the southern European coasts. We assess this result by using bio-energetic modeling, …
