In the city of Genoa (NW Italy) three breeding species of Psittaciformes are knownto occur: Psittacula krameri, Amazona ochrocephala andAmazona aestiva. We planned to update the knowledge of these alien species involving citizens in a project coordinated and managed by professional scientists and technicians from the Universityof Genoa, the Natural...

The introduction of alien fish species in wetland ecosystems could have a great impact on freshwater communities and ecological processes. Despite fish introduction has been noticed as one of the principal cause of freshwater extinctions, ecosystem processes alteration, and change in aquatic community assemblage, very few data about impact on fresh...

A freshwater turtle monitoring programme along the inland margins of the Venice lagoon was initiated in 2019 in collaboration with the World Wild Fund for Nature (WWF-Italy). From a total of 336 European pond turtles (Emys orbicularis) captured and marked, 97 freshwater turtles were recaptured at least once (28.9% return rate) providing important i...

The Sicilian Pond Turtle, Emys trinacris (family Emydidae), is a small-sized freshwater turtle (straight midline carapace length to 172 mm in females, 156 mm in males), endemic to the island of Sicily in Italy. It appears to be more widespread in the northern and central-western parts of the island, with the exclusion of Monti Peloritani and most o...

La testuggine palustre europea è tradizionalmente considerata una specie legata maggiormente ad ambienti planiziali di bassa quota, ma nelle aree più meridionali del suo areale di distribuzione può raggiungere anche quote di media-alta montagna. In questo studio presentiamo i risultati di un monitoraggio condotto nel 2018 che ha interessato quattro...

La presenza di Emys orbicularis all’interno della Riserva Naturale Torrile e Trecasali è nota da tempo, sebbene non siano mai stati condotti studi per approfondire la distribuzione e l'abbondanza della specie all’interno dell’area protetta. In questo lavoro preliminare sono presentati alcuni parametri di popolazione e alcuni aspetti morfometrici de...

Recenti normative e studi scientifici hanno evidenziato le problematiche riguardanti l’introduzione di testuggini alloctone in natura. Nonostante ciò, i dati riguardanti le interazioni con E. orbicularis in aree di sintopia sono tuttora scarsi, anche per la novità del fenomeno che coinvolge specie molto longeve. In questo contesto, l’Oasi Cave di G...

Recently several projects have been implemented for the conservation of the European turtle Emys orbicularis, but few aspects of the captive-bred animals released into the wild have been described. In this note we report about the trophic habits of a small restocked population of the endemic subspecies E. o. ingauna that is now reproducing in NW It...

The lack of data relating to basic life-history and population dynamics is one of the gaps to be filled in order to develop a proper strategy for the conservation of the Sicilian Pond Turtle (Emys trinacris). In this study, we present the results of the first year of a multi-annual monitoring program focusing on a specific wetland area, located wit...

Directive 2000/60/EC arises to develop an European-level regulatory framework capable of supporting integrated Community action in the field of water policy. General objectives are either to prevent the deterioration or to facilitate the improvement of aquatic environments and encourage the sustainable use of water resources. Fish community is one...

The need to identify no-killing monitoring methods for Anguilla anguilla L. stocks has become a crucial requirement according to a management and conservationist perspective. This paper reports the preliminary observations on the enforcement of Silvering Index (Acou et al., 2005) in several basins of the Liguria Region. This Index has been used in...

le informazioni sia sulla sistematica sia sulla biologia dei cestodi che inte- ressano gli anfibi europei sono molto limitate, e fino a poco tempo fa era noto un unico genere: Nematotaenia luhe, 1910 (ricci, 1988). Buriola et al. (2002; 2005) confrontando cestodi provenienti da esemplari parassita- ti di Speleomantes strinatii nell’appennino genove...

Comportamenti territoriali e aggressività verso conspecifici e individui di altre specie sono stati ampiamente descritti nei Pletodontidi nordamericani fin dagli anni ’70. Tali comportamenti sono essenzialmente legati alla spar- tizione degli habitat e delle risorse trofiche, ma sono state evidenziate anche cause riconducibili alla protezione del n...

A seguito dell’incremento demografico del cormorano Phalacrocorax carbo palesatosi in Europa negli ultimi anni sono aumentati i conflitti tra questa specie ittiofaga ed alcune attività umane quali la pesca sportiva e l’acquacoltura. Tali interazioni sono dovute in Italia soprattutto all’incremento delle popolazioni svernanti della sottospecie Phala...

Feeding ecology of a species is the result of its evolutionary history, biology, physiology and local constraints, such as prey availability, intra- and inter-specific interactions and environmental characteristics. In this study we investigated the still unknown diet of the Sicilian pond turtle, with special emphasis to the relationships with rece...

Captive breeding and reintroduction programs remain a powerful but divisive tool for management of threatened species, with a proven potential to avoid extinction, but low long-term success rates and high resource requirements. Monitoring the results of reintroductions is critical to be able to assess short- and long-term success, adjusting managem...

The Biospelogical Station of San Bartolomeo di Savignone is located in the Scrivia Valley (north-western Italy). This horizontal tunnel,measuring about 40 m, was excavated in marlstones during World War II, when it was used as an air-raid shelter. This cavity was naturally colonized by a population of the cave salamander Speleomantes strinatii that...

Presence and distribution of ecological barriers shapes the distribution of migratory birds as well as any other living organism. In Italy, short-toed snake eagles (Circaetus gallicus) breed in the northern and western areas of the peninsula but the species is rare in the south or the islands. The Italian population of this species migrates across...

Lo stock europeo di Anguilla anguilla ha risentito, in tutto il sua areale, di una drastica riduzione a partire dagli Anni '70 del secolo scorso: nel 1980 il reclutamento di cieche registrò una diminuzione del 10% rispetto alle annate precedenti, con un ulteriore decremento quantificato tra l'1 ed il 5% nel 2000: oggi i dati sia di cattura sia di r...

We present the results of modelling the supplementation program for Emys orbicularis in Liguria. We evaluated three possible alternative strategies for the reintroduction, releasing 3-, 4-or 5-year-old turtles. In particular, we wanted to assess the expected population sizes that could be achieved by these release strategies, given environmental an...

The historical presence of Emys orbicularis in Liguria (NW Italy) is confirmed by museum specimens only in the Province of Savona, where the alteration of freshwater habitats have negatively impacted the species, that was considered locally extinct by the end of the last century. However, recent findings proved the existence of few remnant breeding...

North America and the neotropics harbor nearly all species of plethodontid salamanders. In contrast, this family of caudate amphibians is represented in Europe and Asia by two genera, Speleomantes and Karsenia, which are confined to small geographic ranges. Compared to neotropical and North American plethodontids, mortality attributed to chytridiom...
