Geckos Replace Wall Lizards in Southern France: An Ecological Mystery

Geckos Thrive While Wall Lizards Decline in Southern France: Experts Investigate Ecological Shift The Vaucluse region of Provence, in Southern France, is experiencing an ecological shift. Gecko populations are booming, while wall lizard numbers are dwindling. This unexpected change has prompted a discussion among local experts, who are exploring the potential causes of this phenomenon. "The gecko is experiencing a very strong expansion," notes one expert in the recent video. The video highlights that geckos and wall lizards have different habitat preferences. Geckos tend to occupy vertical fissures in walls and buildings, while wall lizards prefer ground-level burrows. This difference in habitat use might reduce direct competition. However, the video also explores the possibility of predation. While adult geckos wouldn't prey on adult wall lizards, they may consume younger ones. This could be a contributing factor to the decline in wall lizard populations. The experts emphasize the need for further research to fully understand the complex interactions at play. The investigation into this ecological shift underscores the importance of monitoring biodiversity changes and the need for further research to understand the intricate relationships within ecosystems. The contrasting fortunes of geckos and wall lizards serve as a reminder of the delicate balance of nature.
