Lizard colour plasticity tracks background seasonal changes.

Environmental heterogeneity on a spatial and temporal scale fosters an organism's capacity to plastically alter coloration. Predation risk might favour the evolution of phenotypic plasticity in colour patterns, as individuals who change colour throughout the year may be able to improve their fitness. Here we explored the change in dorsal pigmentation of the Italian wall lizard () at three time points (March, July, October) during a period of activity in a Mediterranean natural area in southern Italy.

Patterns of ecology and distribution of the tree crickets Oecanthus dulcisonans and O. pellucens (Orthoptera: Gryllidae; Oecanthinae) in southern Italy.

Ecological proclivities of the tree cricket Oecanthus dulcisonans, which has been recently separated from the well known O. pellucens, have been poorly investigated. Moreover, studies on the patterns driving niche segregation between these related species are still needed.
