Bufotes Balearicus) Within the Sentina Regional Natural Reserve (San Benedetto Del Tronto, AP)
Università degli Studi di Camerino Scuola di Scienze e Tecnologie Degree Course in Geological, Natural and Environmental Sciences (L-32) Ecological and biometric analysis techniques on two contiguous populations of green toad (Bufotes balearicus) within the Sentina Regional Natural Reserve (San Benedetto del Tronto, AP) Stage report Graduate: Fiamma Borgni Unicam Tutor: Dott. Mario Marconi Company Tutor: Dott. Stefano Chelli Accademic Year 2018-2019 Abstract La finalità di questo stage è volta allo studio della popolazione di rospo smeraldino (Bufotes balearicus, Laurenti, 1768) durante il periodo di fregola all’interno della Riserva Naturale Regionale della Sentina. Nel corso dei monitoraggi, avendo rinvenuto una consistente popolazione di questa specie nel vicino torrente Ragnola, a 2,2 km di distanza dalla riserva, quest’ultimo è stato incluso nel monitoraggio. Il rilevamento dei dati biometrici (lunghezza e peso) ha coinvolto anche gli altri membri della batracofauna della riserva, onde avere un quadro della situazione più chiaro. È stata rilevata la presenza abbondante di Pelophylax bergeri kl. Hispanicus (Bonaparte, 1839), e una più modesta di Hyla intermedia (Boulenger, 1882), oltre quella del rospo smeraldino, il quale all’interno della riserva sembra soffrire della situazione di instabilità del livello d’acqua dei canali e del regime agricolo attualmente presente. Al torrente Ragnola la popolazione e l’attività di fregola è più stabile. La virtuale assenza del rospo comune, specie euriecia per eccellenza, è degna di nota. Introduction The present study is an analysis of the herpetofauna in the Regional Natural Reserve of Sentina. In particular, our attention has focused on an ecological and biometric analysis of two adjacent populations of green toads (Bufotes balearicus, Laurenti, 1768), a species protected by the Habitat Directive, Annex IV. -
Effectiveness of Artificial Amphibian Breeding Sites Against Non-Native Species in a Public Protected Area in Tuscany, Italy
G. Bruni, G. Ricciardi & A.Vannini / Conservation Evidence (2016) 13, 12-16 Effectiveness of artificial amphibian breeding sites against non-native species in a public protected area in Tuscany, Italy Giacomo Bruni*1, Giulia Ricciardi2 & Andrea Vannini3 1 Centro Iniziativa Ambiente Sestese, Circolo Legambiente, via Scardassieri 47/A, 50019 Sesto Fiorentino, Italy 2 via Leonardo da Vinci 15, 50132 Firenze, Italy 3 via Pompeo Ciotti 60/2, 59100 Prato, Italy SUMMARY The spread of non-native invasive species is among the factors thought to be responsible for the recent global declines in amphibian populations. In a Protected Natural Area of Local Interest in Tuscany, Italy, we tested approaches for preserving the local amphibian populations threatened by the presence of the red swamp crayfish Procambarus clarkii. The construction of artificial breeding ponds, with suitable vertical barriers, was initially effective in preventing the spread of the red swamp crayfish and created a source site for amphibians, in particular newt species. Unfortunately, five years after construction, the breeding sites were colonized by fish and crayfish, possibly due to the actions of members of the public. BACKGROUND importance were still present. Five species of amphibian were observed at the site: Italian crested newt Triturus carnifex, Amphibians are regarded as the most endangered class of smooth newt Lissotriton vulgaris, Italian tree frog Hyla vertebrates (Gibbons et al. 2000, Stuart et al. 2004), and their intermedia, Balearic green toad Bufotes balearicus, and Italian global decline is matter of great concern because of its pool frog Pelophylax bergeri, together with the hybrid species consequences for species conservation and ecosystem function Pelophylax kl. -

Celoria 26, 20133 Milan, Italy Received 13 May 2003; received in revised form 15 November 2003; accepted 17 November 2003 Abstract We studied amphibian populations in a human-dominated landscape, in Northern Italy, to evaluate the effects of patch quality and isolation on each species distribution and community structure. We used logistic and linear multiple regression to relate am- phibian presence during the breeding season in 84 wetlands to wetland features and isolation. Jackknife procedure was used to evaluate predictive capability of the models. Again, we tested the response of each species to habitat features related to the richest communities. Amphibian presence depends strongly on habitat quality and isolation: the richest communities live in fish-free, sunny wetlands near to occupied wetlands. The negative effects of isolation do not seem to be biased by spatial autocorrelation of habitat features. The system shows strong nestedness: amphibian persistence depends on the contemporary effects of species adaptability and mobility. The commonest species, the pool frog (Rana synklepton esculenta) and the Italian tree frog (Hyla intermedia), are able to move through the matrix using canals and hedgerows, and can maintain metapopulations across the landscape; the rarest species (newts and toads) are more sensitive to habitat alteration, and they are strongly affected by isolation effects. If human exploitation of the landscape continues, only few species, mobile and opportunistic, will persist in this landscape. -

Abstract. In this study, we present the results of our field and bibliographic survey on the amphibians of the “Cilento and Vallo di Diano” National Park (Southern Ita- ly). Two hundred and thirty three spawning sites (167 original and 66 derived from literature), and 11 amphibian species were found. Reproductive activity was record- ed for Salamandra salamandra, Salamandrina terdigitata, Triturus carnifex, Lissotri- ton italicus, Bufo bufo, Hyla intermedia, Rana italica, Rana dalmatina and Pelophylax synkl. hispanicus. The distribution record of many species is widely improved with respect to bibliographic data. Our results also suggested that preservation and restora- tion of small aquatic sites, in particular of the artificial ones, such as stony wells and drinking-troughs, are fundamental for an appropriate conservation management of amphibians in the “Cilento and Vallo di Diano” National Park. -
Investigating the Effects of Organic Pollutants on Amphibian Populations in the UK
Investigating the effects of organic pollutants on amphibian populations in the UK A thesis submitted for the degree of Doctor of Philosophy in the Faculty of Science and Technology, Lancaster University Alternative format thesis March 2016 Rebecca Jane Strong (MSc) Lancaster Environment Centre Abstract Amphibians are undergoing dramatic population declines, with environmental pollution reported as a significant factor in such declines. Technologies are required that are able to monitor populations at risk of deteriorating environmental quality in a rapid, high-throughput and low-cost manner. The application of biospectroscopy in environmental monitoring represents such a scenario. Biospectroscopy is based on the vibrations of functional groups within biological samples and may be used to signature effects induced by chemicals in cells and tissues. Here, attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy in conjunction with multivariate analysis was implemented in order to distinguish between embryos, whole tadpoles at an early stage of development and individual tissues of late-stage tadpoles of the common frog collected from ponds in the UK with varying levels of water quality, due to contamination from both urban and agricultural sources. In addition, a Xenopus laevis cell line was exposed to low-levels of fungicides used in agriculture and assessed with ATR-FTIR spectroscopy. Embryos, in general did not represent a sensitive life stage for discriminating between ponds based on their infrared spectra. In contrast, tadpoles exposed to agricultural and urban pollutants, both at early and late stages of development were readily distinguished on the basis of their infrared spectra. ATR-FTIR spectroscopy also readily detected fungicide- induced changes in X.laevis cells, both as single-agent and binary mixture effects. -

LUPI Jonathan Master Thesis 1 Quantification and explanation of the decline in the number of populations of common toad (Bufo bufo), in southern Switzerland. Master thesis 2015 JONATHAN LUPI Department of behavioural ecology University of Neuchâtel, Switzerland Supervised by Dr. Benedikt R. Schmidt, KARCH & University of Zurich, Switzerland Professor of reference Redouan Bshary, Professor in behavioural ecology at the University of Neuchâtel LUPI Jonathan Master Thesis 2 ABSTRACT In conservation biology, one of the main topics is the global loss of biodiversity. According to the researchers, this loss is caused by human activity and global change, which can have a negative effect qualitatively and quantitatively. Habitat quality is influenced by hydroperiods and quantitatively, homogenization of the habitat can have disastrous consequences on the populations of amphibians and their complex life cycle. The loss of long hydroperiods may affect negatively the fitness of amphibians and the homogenization may be caused by high urbanization rate, which fragments and destroys habitat .Often, however, the consequences are discovered and studied too late, and we realize that we have overlooked the important signs of decline. In southern Switzerland (Ticino), a decline in number of populations of common toad (Bufo bufo) in the last decades was observed. Toad was no longer observed in many ponds considered breeding sites with cantonal importance. My goal was to understand what factors may explain decline of B.bufo, and if decline subsists. Results show that decline was confirmed, but the loss in number of populations came to a halt. Permanence of the pond, that is non-drying, is the most important factor that determines the occupation of the species. -

Corresponding author. E-mail: [email protected] Submitted on: 2009, 8th June; revised on: 2009, 17th November; accepted on: 2010, 4th June. Abstract. Little attention has been paid to the herpetological fauna of the Simbruini Mountains Regional Park, Latium (Central Italy). In this study, we surveyed 50 sites in the course of about ten years of field research, especially during the period 2005-2008. Nine amphibian species, four Caudata and five Anura, 60.0% out of the 15 amphibian species so far observed in Latium, were discovered in the protected area: Salamandra salamandra, Salamandrina perspicillata, Lissotriton vulgaris, Triturus carnifex, Bombina pachypus, Bufo balearicus, Bufo bufo, Rana dalmatina, Rana italica. Physiography of sites has been detailed together with potential threatening patterns. For each species the following topics have been discussed; ecology of sites, altitudinal distribution, phe- nology, sintopy. Salamandra salamandra and Bombina pachypus are at higher risk. The importance of the maintenance of artificial/natural water bodies for the conservation management of amphibian population of this territory is discussed. Keywords. Monti Simbruini Regional Park, Italy, Amphibia, distribution, conservation. INTRODUCTION The Simbruini Mountains, recently acknowledged as an Italian Regional Park (the Simbruini Mountains Natural Regional Park, PNRMS), is one of the largest protected areas of Central Italy and preserves an high biodiversity of both animals and plants (e.g., 1508 species and subspecies of vascular plants among which 18.3% are rare or extremely rare in the territory of Latium (Attorre et al., 2000).
