Tail shedding in island lizards [Lacertidae, Reptilia]: decline of antipredator defenses in relaxed predation environments.
The ability of an animal to shed its tail is a widespread antipredator strategy among lizards. The degree of expression of this defense is expected to be shaped by prevailing environmental conditions including local predation pressure. We test these hypotheses by comparing several aspects of caudal autotomy in 15 Mediterranean lizard taxa existing across a swath of mainland and island localitie...
متن کاملEvolution of antipredator behavior in an island lizard species, Podarcis erhardii (Reptilia: Lacertidae): The sum of all fears?
Organisms generally have many defenses against predation, yet may lack effective defenses if from populations without predators. Evolutionary theory predicts that "costly" antipredator behaviors will be selected against when predation risk diminishes. We examined antipredator behaviors in Aegean wall lizards, Podarcis erhardii, across an archipelago of land-bridge islands that vary in predator ...
متن کاملSpeciation in mountains: phylogeography and phylogeny of the rock lizards genus Iberolacerta (Reptilia: Lacertidae).
The vertebrate faunas in Southern Europe have a higher specific richness than in central and northern Europe and a high level of endemism (see, e.g., Baquero and Telleria, 2001; Meliadou and Troumbis, 1997), both probably related to the presence of faunal refugia during the Pleistocene glacial episodes (Hewitt, 1996, 1999; Taberlet et al., 1998). This scenario implies that the Pleistocene glaci...
متن کاملRelationships of lacertid lizards (Reptilia: Lacertidae) estimated from mitochondrial DNA sequences and morphology.
DNA sequences from parts of the 12S, 16S and cytochrome b mitochondrial genes, which totalled 1049 aligned base pairs, were used to estimate the relationships of 49 species of Lacertidae, including representatives of 19 out of the 23 recognized genera and 23 species of the paraphyletic genus Lacerta. These data were used, together with morphological information, to estimate the relationships wi...
متن کاملCoexistence Shapes Antipredator Defenses
8 Invasive alien predators can impose strong selection on native prey populations and induce rapid 9 evolutionary change in the invaded communities. However, studies on evolutionary responses to 10 invasive predators are often complicated by the lack of replicate populations differing in 11 coexistence time with the predator, which would allow determining how prey traits change during 12 the in...
