Il numero di spiaggiamenti di tartarughe marine avvenuti durante il 2009 è stato particolarmente elevato in rapporto agli anni precedenti. Oltre alle più comuni cause di spiaggiamento, dovute soprattutto alla cattura accidentale durante le operazioni di pesca e all'impatto con natanti a motore, è stato rilevato un insolito numero di giovani di Caretta caretta debilitati e fittamente ricoperti da piccoli balani, fenomeno che mostra alcune analogie con la cosiddetta "debilitated turtle syndrome". Di particolare interesse anche lo spiaggiamento di una tartaruga liuto (Dermochelys coriacea) al Lido di Venezia. Come di consueto vengono riportate in ordine cronologico le segnalazioni per l'anno 2009, raccolte grazie agli sforzi di un costituendo coordinamento locale per la conservazione delle tartarughe marine nel Veneto e di numerosi altri collaboratori. Summary. Records of sea turtles in the Lagoon of Venice and along the Venetian coast-Year 2009 (Reptilia, Testudines). The number of marine turtle strandings occurred in 2009 has been especially high as compared to previous years. In addition, on top of usual stranding causes, i.e.: fisheries operation by-catching and impact with motorboats, an unusually large number of debilitated young Caretta caretta, extensively covered by small barnacles, was recorded; such a phenomenon apparently shares several analogies with the so-called "debilitated turtle syndrome". It is also noteworthy the stranding of a Leatherback turtle (Dermochelys coriacea) at Lido di Venezia. As usual, all records for 2009 are reported in chronological order; they had been collected thanks to the effort of the establishing local network for the conservation of sea turtles in Venetia, as well as of many others collaborators.

However, although frequently treated in marine animal rescue centers, and the subject of several studies in literature, as yet, few studies have been conducted on large numbers of loggerhead sea turtles in order to establish physiological reference ranges that enable the identification of pathological values. The lack of studies on reference parameters probably depends on the fact that marine turtles treated in wildlife rescue centers are usually in a critical conditions, thus precluding the collection of data on healthy animals and compromising the reliability of any data obtained from them. The present biological study was therefore conducted in order to obtain a database from healthy animals in natural conditions. Serum biochemistry and serum protein electrophoresis were performed on blood samples obtained from 65 healthy adult loggerhead sea turtles captured and delivered to the Sea Turtle Rescue Center of Linosa (Italy); the blood samples were collected during the clinical examination of rescued animals. Laboratory analyses of serum samples were made in order to establish reference parameters, commonly required for laboratory diagnoses in mammals and diseased animals.

These animals have to be hand reared, weaned and most of the times, they needs veterinary care. This work describes the most common injuries, parasites and nutritional disorders recorded in these patients during hand rearing and rehabilitation. Bats are amazing creatures with a particular biological cycle. In the time of a year they have to concentrate hibernation, mating, gestation, lactation, weaning and pre-hibernation feeding to fat themselves for hibernation time again. Our knowledge of the reproductive biology of European bat species is still very sketchy. Bats are placental mammals, in the most of European insectivorous species the length of gestation is unknown: the females give birth to one or two young in nurseries (maternity roosts) in a limited period that in Italy is from the end of June to the beginning of August. Newborn are naked, blind but with milk teeth that allows to the babies to take a firm grasp to the nipple and the fur of the mother. Until they are independent, the young are nourished by mother milk. They begin able to fly at three-four weeks of age. The young are weaned by their mothers by teaching in catching insects. Weaning usually takes few weeks Adult animals are usually submitted during or just after the end of hibernation time. In juveniles, the most common pathologies are related to a not correct hand rearing or diet management, that bring to metabolic bones diseases (rickets, vitamin C deficiency) skin disorders and diseruption of teeth. In adult specimens fractures of wings and patagium often occurs. Metabolic disorders in captive bats are also common and due to a not appropriate management.

Thanks to the agreement between CAI Veneto and the Veneto Region, from 2017 to 2021, 40 interventions have been carried out for the construction of electrified fences and 15 interventions to search for animals escaped after predator events. To date, 15.500 meters of nets have been placed and the fences used during the interventions are mobile, semi-permanent and fixed throughout the Veneto Alps in the provinces of Belluno, Verona and Vicenza.
