Diet and Trophic Niche Overlap of Three Toad Species (Amphibia, Anura) from Poland

Natural Diet of European Green Lizards, Lacerta viridis (Squamata: Lacertidae): A Comparison of Macroscopic and Molecular Identification Methods

“…We found that European Green Lizards are opportunistic predators of arthropod prey with a moderate breadth of trophic niche (in the taxonomic dimension), which agrees with former studies (Korsós 1984; Maier et al 2020). Using both methods of prey detection, we found 13 arthropod orders, which is similar to findings of other studies using macroscopic prey identification in the same (Mollov et al 2012) or related lacertids (Hódar et al 1996; Mollov and Petrova 2013). Representatives of the family Lacertidae are mostly carnivorous, catching particularly invertebrates, with a tendency to omnivory in the case of a shortage of standard prey (Iverson 1982; Valido and Nogales 2003; Herrel et al 2004).…”

Road-killed toads as a non-invasive source to study feeding ecology of migrating population

“…Differences in food composition, as well as the abundance of particular prey taxa in comparison with other studies (e.g. Gittins 1987;Mollov and Stojanova 2010;Crnobrnja-Isailović et al 2012;Čađenović et al 2018), result primarily from seasonal changes in prey diversity (Gittins 1987;Kovács et al 2007). However, other factors, such as habitat type, prey availability, the presence of competitors, and body size, influence amphibian diets (Houston 1973;Gittins 1987;Denton and Beebee 1994;Isacch and Barg 2002;Crnobrnja-Isailović et al 2012).…”
