We present unpublished data on the diet of three lizards (Lacerta trilineata, Lacerta agilis and Podarcis tauricus) from the Lacertidae family, collected in 1974 in few localities in Southern Bulgaria. The analyzed data showed that the insects (Insecta) are the most numerous and the most frequently met food component and among the non-insect components the spiders and isopods are slightly predominating. The largest niche breadth was recorded in Podarcis tauricus (6.135), followed by Lacerta trilineata (5.263) and Lacerta agilis (4.132). All three studied lacertid species are classified as opportunistic general feeders (polyphages), which may show slight preference towards beetles, ants or spiders, depending on the occupied habitat or the season. |
