First observations of oophagy in a wild population of the sand boa (Eryx jaculus)

The sand boa Eryx jaculus (Linnaeus, 1758) is found in the southern Balkans, Middle East and North Africa (Sindaco et al., 2013). Only recently The presence of this species has been confirmed in Italy, in a small area of southern Sicily (Insacco et al., 2015). Knowledge of the sand boa in Sicily is limited with few data on geographical distribution, morphology, and habitat (Insacco et al., 2015; Faraone et al., 2017). Even at a global scale the biology of this species is little known due to its secretive habits (Tokar & Obst, 1993).

ANNUAL ACTIVITY CYCLE OF THE JAVELIN SAND BOA ERYX JACULUS (LINNAEUS, 1758) IN SICILY

The Javelin sand Boa Eryx jaculus is a snake little known from an eco-ethological point of view. Here, some aspects of its phenology are described for the first time. 229 observations were collected in Sicily, with the aim of describing the annual activity of this population. The activity of adult males and juveniles presents a similar trend, with a sharp peak between May and July. Juveniles sharply declined in the following months. Adult females have three peaks of activity of similar amplitude. The activity cycle of the Javelin sand Boa could be modulated by some aspects of his trophic behaviour. In fact, juveniles and adult males prefer prey types highly available only during their maxim…

Stima dei flussi energetici all’interfaccia aria-mare con l’impiego di SST da Satellite e dati rilevati in situ.

La conoscenza dei flussi energetici scambiati fra oceano e bassa atmosfera è un requisito utile per modellare e comprendere il sistema climatico e la dinamica degli oceani. L’elevata difficoltà di effettuare misure in situ ed in continuo in ambiente marino induce spesso all’utilizzo ausiliario di strumentazione satellitare. Nel presente lavoro è stato effettuato un confronto tra la stima dei flussi energetici superficiali valutati con dati provenienti da satellite e quelli ottenuti da misure in situ. In particolare, per il confronto, sono stati utilizzati i dati SST acquisiti dal satellite NOAA e i dati raccolti in situ dai sensori istallati a bordo della Nave Oceanografica Urania nel corso…

Census of the Sicilian rock partridge Alectoris graeca whitakeri population in ZPS ITA010029 Monte Cofano, Capo San Vito and Monte Sparagio

During the project "LIFE09 NAT/IT/000099-SICALECONS-Urgent actions for the conservation of Alectoris graeca whitakeri", this species was censused in the ZPS ITA010029 Monte Cofano, Capo San Vito and Monte Sparagio (Trapani province, Sicily) with playback technique between March and April 2011. Superimposing a UTM grid of 1 km mesh on the study area produced cells of 100 hectares. Using a GPS satellite receiver we reached, where possible, the centre of each cell from where the cospecific call was broadcasted. A total of 163 listening stations were implemented. Using software GIS ARCMAP 10.0 (ESRI) presence data were interpolated with vegetational and phytosociological maps (CORINE) to establ…
