Leonardo Vignoli currently works at the Department of Science, Universita Degli Studi Roma Tre. Leonardo does research in Ecology, Zoology and Animal Communications. I have several ongoing projects on animal ecology. Here some examples: Impact of Bullfrogs on native Amphibians and Reptiles in Central Italy; Feeding strategy in the invasive anuran American bullfrog; Long term (>20 years) monitoring and demgraphy of Salamandrina perspicillata and Rana italica; Ecology, genetics and conservation through captive breeding of the Italian endemic amphibians Euproctus platycephalus and Bombina pachypus; Assemblage structure of Odonata in natural and artificial habitats Nestedness and co-occurrence pattern in Odonata at global and local scales; Ecotoxicology of lizards in rural habitats
