Data from: Local adaptation has a role in reducing vulnerability to climate change in a widespread Amazonian forest lizard

The extant genetic variation within and among taxa reflects a long history
of diversification and adaptive mechanisms in response to climate change
and landscape alterations. However, the velocity of current anthropogenic
changes poses an imminent threat to global biodiversity. Understanding how
species and populations might respond to global climate change provides
valuable information for conservation in the face of these impacts. Here,
we use genomic data to look for candidate loci under climate selection and
test for genetic vulnerability to climate change in a widespread Amazonian
ombrophilous lizard. We found nine populations across Amazonia with a
considerable amount of admixture among them. Distinct approaches of
genome-environment association analyses recovered 56 candidate SNPs under
climatic selection, recovering an east-to-west gradient in the adaptive
landscape and showing a signal of local climate adaptation across the
species range. According to our results, signals of local adaptation
indicate that the species may not respond equally throughout its range,
with some populations facing higher extinction risks. Genomic offset
analysis predicts the south and central portions of Amazonia with higher
vulnerability to future climate change. Our findings highlight the
importance of considering spatially explicit contexts with large sampling
coverage in evaluating how local adaptation and climatic vulnerability
will affect Amazonian Forest ectothermic fauna.
