| introgression of mtdna in urosaurus lizards: historical and ecological processes. | introgression of mtdna appears common in animals, but the implications of acquiring a novel mitochondrial genome are not well known. this study investigates mito-genome introgression between the lizard species urosaurus graciosus, a thermal specialist, and u. ornatus, a species that occupies a wider range of thermal environments. as ectotherms, their metabolic rate is strongly influenced by the thermal environment; with mitochondria being linked to metabolic rates, overall energy budgets could b ... | 2017 | 27864892 |
| phylogeny, biogeography, and display evolution in the tree and brush lizard genus urosaurus (squamata: phrynosomatidae). | the brush and tree lizards (urosaurus) are a small clade of phrynosomatid lizards native to western north america. though not as well known as their diverse sister clade, the spiny lizards (sceloporus), some urosaurus have nonetheless become model organisms in integrative biology. in particular, dramatic phenotypic and behavioral differences associated with specific mating strategies have been exploited to address a range of ecological and evolutionary questions. however, only two phylogenies ha ... | 2011 | 21871967 |
