Rapid Adaptation in Anolis Lizards After Hurricanes
Rapid Adaptation in Anolis Lizards After Hurricanes
Anolis lizards have demonstrated remarkable adaptability to environmental changes, ensuring their survival across diverse habitats. In a study by Donihue et al. (2018), researchers examined how Anolis scriptus, native in the Turks and Caicos, responded to Hurricanes Irma and Maria. By comparing populations before and after the storms, they discovered that surviving lizards had traits associated with better clinging ability. These included larger toepads and longer forelimbs.

These traits gave them more survival advantage because they helped the lizards hold onto surfaces during extreme winds. The changes were consistent across both islands, suggesting that the hurricanes caused natural selection. The researchers also found reduced variation in these traits, describing that only individual with certain physical features survived.

The study ruled out other possible explanations like gene flow or genetic drift. Since the changes occurred in adult lizards over a span of six weeks, the researchers concluded that the storms directly influenced survival, shaping the gene pool for these traits.

This case shows that Anolis lizards can rapidly adapt to sudden environmental pressures, not just in a long-term. As extreme weather events become more frequent due to climate change, such studies help scientists understand how ecosystems can respond and adapt. Anolis lizards, with their quick evolutionary responses, serve as an example of nature’s resilience and adaptability in the face of environmental disturbance.
