A unified model of species abundance, genetic diversity, and functional diversi...
Overcast, Isaac; Ruffley, Megan; Rosindell, James; Harmon, Luke; Borges, Paulo A. V.; Emerson, Brent C.; Etienne, Rampal S.; Gillespie, Rosemary G.Biodiversity accumulates hierarchically by means of ecological and evolutionary processes and feedbacks. Within ecological communities drift, dispersal, speciation, and selection operate simultaneously to shape patterns of biodiversity. Reconciling the relative importance of these is hindered by current models and inference methods, which tend to focus on a subset of processes and their resulting predictions. H...
Quaternary climate changes as speciation drivers in the Amazon floodplains
Thom, Gregory; Xue, Alexander T.; Sawakuchi, André Oliveira; Ribas, Camila Cherem; Hickerson, Michael J.; Aleixo, Alexandre; Miyaki, Cristina YumiThe role of climate as a speciation driver in the Amazon has long been discussed. Phylogeographic studies have failed to recover synchronous demographic responses across taxa, although recent evidence supports the interaction between rivers and climate in promoting speciation. Most studies, however, are biased toward upland forest organisms, while other habitats are poorly explored and could hold valuable infor...
Phenotypic and genetic structure support gene flow generating gene tree discord...
Thom, Gregory; Amaral, Fábio Raposo do; Hickerson, Michael J.; Aleixo, Alexandre; Araújo-Silva, Lucas Eduardo; Ribas, Camila CheremBefore populations become independent evolutionary lineages, the effects of micro evolutionary processes tend to generate complex scenarios of diversification that may affect phylogenetic reconstruction. Not accounting for gene flow in species tree estimates can directly impact topology, effective population sizes and branch lengths, and the resulting estimation errors are still poorly understood in wild popula...
