Biometrical Analyses of a Sicilian Green Toad, Bufo siculus (Stöck et al. 2008), Population Living in Sicily (Italy)

2013

Se realizo un estudio morfometrico de la estructura del sapo verde siciliano de la Reserva Natural "Monte Pellegrino" (norte-oeste de Sicilia). Un total de 666 individuos (354 machos y 312 hembras) fueron capturados desde el ano 2003 durante la epoca de reproduccion. Se encontraron diferencias estadisticamente significativas entre los dos sexos, donde el peso corporal fue el mejor parametro (hasta 92% de clasificacion correcta), seguido por la longitud corporal (hasta 90% de clasificacion correcta). El uso simultaneo de todos los caracteres examinados solo aumento un 1% la probabilidad de una correcta discriminacion del sexo. En comparacion con la dimension de otras poblaciones de sapos ver…

Multivariate analysis of sites using water invertebrates and land use as indicators of the quality of biotopes of Mediterranean relic plant (Petagnae…

2007

Petagnaea gussonei is a rhizomatous, perennial scapose hemicryptophyte species belonging to a monospecific genus of Apiaceae. It lives only along woodland rivulets and is a Tertiary relic localized in the restricted area of the Nebrodi Mountains (NE Sicily, Italy). Ecological indicators have been employed to understand the status of eight localities (intermittent rivulets) where the species occurs. In order to evaluate both the rivulets' water-quality and landscape use, index of anthropisation (Ia), water fleas bioassay (TU), and analyses of water macroinvertebrates have been employed. The results obtained for the level of toxicity exclude the presence of macropollutants (TU < 0.001), where…

Studio botanico finalizzato al recupero del paesaggio vegetale dell’Area archeologica di Lilibeo presso Marsala (Sicilia occidentale)

2013

Viene presentato uno studio botanico volto al recupero del paesaggio vegetale dell’Area Archeologica di Capo Lilibeo (Marsala). Il progetto prevede l’eradicazione delle specie esotiche ad alto grado di invasività quali Ailanthus altissima e Vachellia karroo, il risanamento fitosanitario dei viali di Palme delle Canarie e la sostituzione degli individui malformati con specie ornamentali altamente decorative e a basso grado di invasività. E’ previsto l’impiego di specie afferenti agli stadi più evoluti dei sigmataxa Chamaeropo humilis- Querceto calliprini sigmetum ed al Pistacio lentisci- Chamaeropo humilis sigmetum al fine di assicurare i migliori risultati contro l’espansione della componen…

DISTRIBUTION OF BOTRYOSPHAERIACEAE SPECIES ASSOCIATED WITH GRAPEVINE DECLINE IN WESTERN SICILY.

2011

Recently, the pathogenicity of different Botryosphaeraceae species on grapevines has been reported from many European and extra-European areas. During summer 2008, in a Sicilian vineyard located in the Marsala area (TP), we observed a decline induced by Lasiodiplodia theobromae. The occurrence and quite rapid spread of the disease seemed to support the regional variability of the species in question, which is retained a tropical and subtropical pathogen to different trees. In the last two years, the decline syndrome has been observed in the following other grape-growing areas of western and central Sicily: Alcamo and Salemi (TP), Montevago (AG) and Milena (CL). From declining plants showing…

Updated status of Anostraca, Notostraca and Spinicaudata (Crustacea Branchiopoda) in Sicily (Italy): review and new records.

2006

A survey on distribution, phenology and status of large branchiopod crustaceans (Branchiopoda: Anostraca, Notostraca, Spinicaudata) in Sicily and in circum-Sicilian islands was carried out from autumn 2000 to winter 2004/2005 with the purpose of providing an organised contribution to the knowledge of the distribution of these crustaceans in the region. Data from literature on Sicilian large branchiopods has been briefly reviewed, and field surveys allowed us to add new data on their actual consistency in the area. Current Sicilian large branchiopod fauna is characterised by a low species richness and diversity, having possibly been impoverished by the high anthropic impact which has interes…

Diversity, relationships and conservation of Sicilian wild taxa of Brassica: an overview

2016

Although lots of studies have been carried out through various analytical approaches and at different taxonomic levels, this overview reveals that actually a comprehensive biosystematic survey on the Mediterranean wild populations of Brassica oleracea group is still lacking.
