Outline of Final Research Achievements |
In Cuba, the Anolis lizard A. homolechis usually inhabits in forest edges, while we found a population where lizards inhabit in a hot and dry semi-desert habitat. The results of behavioral experiments for temperature tolerance showed that the maximum running speeds decreased from 30℃ to 35℃ conditions in the forest population, but did not decreased in semi-desert population. Using SNPs detected by RAD-seq, STRUCTURE analysis showed that the forest population (Los Cardelos) and semi-desert population showed slightly different genetic structure. Between the two populations, 5 SNPs were detected as loci that subject to divergent selection using LOSITAN. RNA-seq was conducted to detect differentially expressed genes (DGE) between 33℃ and 36℃ conditions for individuals from the forest and semi-desert populations. The results showed that 78 and 36 DGE were detected in the forest and semi-desert populations, respectively.
