| local adaptation in mainland anole lizards: integrating population history and genome-environment associations. | environmental gradients constrain physiological performance and thus species' ranges, suggesting that species occurrence in diverse environments may be associated with local adaptation. genome-environment association analyses (geaa) have become central for studies of local adaptation, yet they are sensitive to the spatial orientation of historical range expansions relative to landscape gradients. to test whether potentially adaptive genotypes occur in varied climates in wide-ranged species, we i ... | 2018 | 30598788 |
| inferring responses to climate dynamics from historical demography in neotropical forest lizards. | we apply a comparative framework to test for concerted demographic changes in response to climate shifts in the neotropical lowland forests, learning from the past to inform projections of the future. using reduced genomic (snp) data from three lizard species codistributed in amazonia and the atlantic forest (anolis punctatus, anolis ortonii, and polychrus marmoratus), we first reconstruct former population history and test for assemblage-level responses to cycles of moisture transport recently ... | 2016 | 27432951 |
| a mid-pleistocene rainforest corridor enabled synchronous invasions of the atlantic forest by amazonian anole lizards. | shifts in the geographic distribution of habitats over time can promote dispersal and vicariance, thereby influencing large-scale biogeographic patterns and ecological processes. an example is that of transient corridors of suitable habitat across disjunct but ecologically similar regions, which have been associated with climate change over time. such connections likely played a role in the assembly of tropical communities, especially within the highly diverse amazonian and atlantic rainforests ... | 2016 | 27564209 |
