    • "We suggest that measures to prevent the production and release of Japanese quail and hybrids should be taken rapidly, at least in France, Spain and Italy where they have been found in the wild. Following the decline of wild common quail populations in Europe, releases of animals and organized captive breeding were carried out in Italy around 1950 (Andreotti et al. 2001). Since 1970, these restocking operations have mainly been carried out in southern Europe with Japanese and hybrid quails, and from 10,000 to over 100,000 birds are released each year (Guyomarc'h 2003; Barilani et al. 2005; Puigcerver et al. 2007).

    ABSTRACT: Many cases of introgressive hybridization have been reported among birds, particularly following introduction to the natural environment of individuals belonging to non-native similar taxa. This appears to be the case for common quail (Coturnix coturnix) in France where wild populations artificially come into contact with domesticated Japanese quail (Coturnix japonica) raised for meat and egg production but sometimes released for hunting purposes. In order to highlight the possible existence of gene flows between both taxa, a comparison of nuclear (25 microsatellite loci) and mitochondrial (sequencing and RFLP) DNA polymorphisms was performed on 375 common quails (from France, Spain and Morocco) and 140 Japanese quails (from France and Japan). Genetic diversity was assessed, and analyses (Factorial Correspondence Analysis, Bayesian admixture) of molecular polymorphisms revealed clear differentiation between the two taxa, making it possible to detect for hybrids among quails sampled in the wild. Eight birds expected to be common quail were found to be two pure Japanese quail, one probable backcross to C. japonica, three F1/F2 hybrids, and two probable backcrosses to Coturnix coturnix. These results show that Japanese quails were released and suggest that the two taxa hybridize in the wild. They confirm the urgent need for preventing the release of pure Japanese or hybrid quails to preserve the genetic integrity of C. coturnix. The tools developed for this study should be useful for accurate monitoring of wild quail populations within the framework of avifauna management programs.

Una prima analisi dei dati immessi permette di confermare e quantificare quanto già affermato nelle sintesi sull'argomento precedentemente elaborate (Baccetti et al., 1997; Andreotti et al., 2001): la presenza di Uccelli alloctoni sul territorio italiano è un fenomeno in netta e rapida espansione geografica (Fig. 4) ed in incremento anche per quanto riguarda il numero di segnalazioni e specie avvistate (Fig. 5).

    • "Naturalized species are abundant in the study area. Those species linked to wet ecosystems are locally the more abundant species, naturalized and/or have the greater impact on economic activities and biodiversity (Procambarus clarkii, Gambusia sp., Rattus norvegicus, Myocastor coypus; Andreotti et al. 2001). Alien invasive species may change the diet of many authochtonous species (Cabral et al. 2004). "

    ABSTRACT: The aim of this work is to provide an account of alien species richness and composition in a remnant Mediterranean coastal wetland of Central Italy. Data were obtained from different taxa-specific methods, in 2001–2005 (terrestrial vertebrates) and in 2005 (fish, arthropoda, mollusca). Among the 353 species sampled, 17 (4.8 %) are aliens (7.1% if we consider only vertebrates).Data on abundance, introduction type and status of alien species are reported. A crustacean, Procambarus clarkii, a fish, Gambusia sp. and three rodents, Myocastor coypus, Rattus norvegicus and Mus domesticus are the naturalized invasive species that locally could constitute a threat on economic and ecological levels. Data on Agapornis nigrigenis and Quelea cardinalis represent the first records for Italy. We also report evidence of a food chain on three levels, among the most invasive species (predation of Gambusia sp. by Procambarus clarkii and of Rattus norvegicus on Procambarus clarkii).
