Racing amidst change: urbanization and climate alter functional traits and distribution of an Amazonian parthenogenetic lizard

Habitat modification, including global climate change, deforestation, and urbanization, poses significant challenges for species. For organisms that can persist and thrive in altered landscapes, new habitat structures may lead to niche expansion and phenotypical changes. Here, we investigated the variation in morphology and thermal physiology between natural and neonative (urban) populations of Gymnophthalmus underwoodi Grant, 1958, a parthenogenetic lizard found in the Amazonia, and forecasted its current and future distribution under climate change scenarios. We compared morphological and thermal traits and assessed urban environments as a potentially stressful habitat using asymmetry indexes. Additionally, we utilized a hybrid species distribution model to infer potential dispersion routes and changes in the species’ distribution until 2100 under different climate change scenarios. We found that the neonative population demonstrates enhanced sprint performance compared to the native ..., , # Racing amidst change: urbanization and climate alter functional traits and distribution of an Amazonian parthenogenetic lizard
