Sistema Integrato Multicentrico di Indicatori. Rapporto 2005. Provincia di Parma.

The SIMI (Integrated System of Indicators multicenter) Project contributes to the development of an integrated management of informative data streams related to drug addicted persons. This report analyzes the phenomenon of addiction on the territory of the Parma Province through a description of the network services that provide care and rehabilitation of those addicted. Besides the characteristics of users of local services for addictions, has been developed the analysis of the subjects reported to the prefectures for use of illegal drugs and any action taken. Standard methods of estimation were also applied to quantify the proportion of users of substances that do not relate to services and to identify certain characteristics.Il Progetto SIMI (Sistema Integrato Multicentrico di Indicatori) intende contribuire allo sviluppo di una gestione integrata e sinergica dei flussi informativi relativi ai consumatori di sostanze stupefacenti afferenti alle diverse amministrazioni dello Stato. In linea con quanto proposto dall\u27Osservatorio europeo di Lisbona, per la descrizione e analisi del fenomeno connesso all\u27uso/abuso di sostanze, risulta di fondamentale importanza la possibilit? di ottenere informazioni esaustive e comparabili sulle persone che usano e/o abusano di sostanze psicotrope. Il presente rapporto analizza il fenomeno delle dipendenze sul territorio della provincia di Parma attraverso la descrizione della rete dei servizi preposti alla cura e riabilitazione dei soggetti tossicodipendenti. Accanto alle caratteristiche degli utenti dei servizi territoriali per le dipendenze, ? stata sviluppata l\u27analisi dei soggetti segnalati alle Prefetture per uso di sostanze illegali e degli eventuali provvedimenti adottati. Sono state inoltre applicate metodologie standard di stima per quantificare la quota parte di utilizzatori di sostanze che non afferiscono ai servizi e per identificarne alcune caratteristiche

Pug-Headedness Anomaly in a Wild and Isolated Population of Native Mediterranean Trout Salmo trutta L., 1758 Complex (Osteichthyes: Salmonidae)

Skeletal anomalies are commonplace among farmed fish. The pug-headedness anomaly is an osteological condition that results in the deformation of the maxilla, pre-maxilla, and infraorbital bones. Here, we report the first record of pug-headedness in an isolated population of the critically endangered native Mediterranean trout Salmo trutta L., 1758 complex from Sardinia, Italy. Fin clips were collected for the molecular analyses (D-loop, LDH-C1* locus. and 11 microsatellites). A jaw index (JI) was used to classify jaw deformities. Ratios between the values of morphometric measurements of the head and body length were calculated and plotted against values of body length to identify the ratios that best discriminated between malformed and normal trout. Haplotypes belonging to the AD lineage and the genotype LDH-C1*100/100 were observed in all samples, suggesting high genetic integrity of the population. The analysis of 11 microsatellites revealed that observed heterozygosity was similar to the expected one, suggesting the absence of inbreeding or outbreeding depression. The frequency of occurrence of pug-headedness was 12.5% (two out of 16). One specimen had a strongly blunted forehead and an abnormally short upper jaw, while another had a slightly anomaly asymmetrical jaw. Although sample size was limited, variation in environmental factors during larval development seemed to be the most likely factors to trigger the deformities

Small-scale crayfish distribution modelling of the invasive crayfish Procambarus clarkii in the Molentargius-Saline Regional Natural Park (Sardinia, Italy) in response to environmental variables

The crayfish, Procambarus clarkii, is among the worst invasive species capable of disperse overland, aiding the invasion of new environments. Because management options are limited once crayfish become established, there is a critical need to identify the suitable habitats for this invasive species. In this study, we forecast the potential distribution of crayfish based on environmental predictors in the Molentargius-Saline Regional Natural Park (Sardinia, Italy). Current known distribution was used to build correlative species distribution models (SDMs) and forecast distribution in the entire area. We considered, during the spring season, 5 quantitative environmental descriptors at the local scale (Depth, Water Temperature, Salinity, pH and Dissolved Oxygen). Single station data were used to generate synoptic distribution of environmental factors through the inverse distance weighted deterministic interpolation (IDW). The SDMs obtained through 2 different algorithms showed very good performance: GBM (General Boosted Models, ROC=0.847) and RF (Random Forest, ROC=0.996). For GBM the predicted distribution correlated most significantly with environmental variables (Salinity, Dissolved Oxygen and pH), while for RF all variables are homogeneously significant. Identified best models, performed by the Ensemble Modeling technique, showed that most of the areas outside the currently known distribution may offer potential habitats for P. clarkii. Greater probability to find the species presence were computed in correspondence of the Deflux Channel and ESF6B basin of the EcoSistema Filtro. However, for the Bellarosa Minore basin the forecast spread of the species is evident in all the tanks with large dense patches. Presented results deepen the knowledge about distribution patterns of P. clarkii in the Regional Natural Park. Moreover, the ongoing study gives a basic background for the future development of management strategies.
