Abstract
Spiny lizards (genus Sceloporus) represent one of the most diverse and species rich clades of squamate reptiles in continental North America. Sceloporus contains 90+ species, which are partitioned into 21 species groups that contain anywhere from one to 15 species. Despite substantial progress towards elucidating the phylogeographic patterns for many species, efforts to resolve the phylogenetic relationships among the species groups remain limited. In this study, the phylogenetic relationships of 53 species of Sceloporus, representing all 21 species groups, are estimated based on four nuclear genes (BDNF, PNN, R35, RAG-1; >3.3 kb) and contrasted with a new mitochondrial DNA genealogy based on six genes (12S, ND1, ND4, and the histidine, serine, and leucine tRNA genes; > 2.5 kb). Species trees estimated from the nuclear loci using data concatenation or a coalescent-based inference method result in concordant topologies, but the coalescent approach provides lower resolution and support. When comparing nuclear versus mtDNA-based topologies for Sceloporus species groups, conflicting relationships outnumber concordant relationships. Incongruence is not restricted to weak or unresolved nodes, as might be expected under a scenario of rapid diversification, but extends to conflicts involving clades receiving strong support. The points of concordance and conflict between the nuclear and mtDNA data are discussed, and arguments for preferring the species trees estimated from the multilocus nuclear data are presented.
