| prey capture kinematics of ant-eating lizards. | while morphological and behavioral feeding specializations are obvious in many vertebrate groups, among lizards there appear to be few dietary specialists. by comparing the prey capture kinematics and overall feeding behavior in two highly specialized ant-eating lizards (moloch horridus and phrynosoma platyrhinos) with those of two closely related dietary generalists (pogona vitticeps and uma notata), we investigate whether dietary specialization has been accompanied by changes in the function a ... | 2005 | 15601883 |
| lineage diversification of fringe-toed lizards (phrynosomatidae: uma notata complex) in the colorado desert: delimiting species in the presence of gene flow. | multi-locus nuclear dna data were used to delimit species of fringe-toed lizards of the uma notata complex, which are specialized for living in wind-blown sand habitats in the deserts of southwestern north america, and to infer whether quaternary glacial cycles or tertiary geological events were important in shaping the historical biogeography of this group. we analyzed ten nuclear loci collected using sanger sequencing and genome-wide sequence/single-nucleotide polymorphism (snp) data collected ... | 2017 | 27640953 |
| the coachella valley fringe-toed lizard (uma inornata): genetic diversity and phylogenetic relationships of an endangered species. | a phylogeny was reconstructed for 23 populations of fringe-toed lizards (genus uma) from the three most northern species of the genus, including the mojave fringe-toed lizard u. scoparia, the colorado desert fringe-toed lizard u. notata, and the endangered coachella valley fringe-toed lizard u. inornata. the outgroup taxa were the zebra-tailed lizard, callisaurus draconoides; the lesser earless lizard, holbrookia maculata; and the greater earless lizard, cophosaurus texanus. evaluation of 1630 c ... | 2001 | 11277627 |

| photoperiodic response of female fringe-toed lizards. | uma notata females were held over the winter under 24 hours of light per day. these animals laid from two to four clutches of eggs, with 4 to 7 weeks between clutches. clutches contained two to four eggs. additional light is believed to be more important than heat in causing this response. | 1961 | 17797810 |
| a new cryptic species of fringe-toed lizards from southwestern arizona with a revised taxonomy of the uma notata species complex (squamata: phrynosomatidae). | fringe-toed lizards (uma) are among the most specialized lizards in north america, adapted to insular windblown sand habitats in the hyper-arid southwestern deserts, with allopatric distributions, subtle morphological variation, and an unstable taxonomic history. we analyzed a morphological dataset of 40 characters for 65 specimens and a molecular dataset of 2,286 bases from three mitochondrial loci for 92 individuals and interpreted these data alongside published analyses of multi-locus genetic ... | 2020 | 33055832 |
| the first known fossil uma: ecological evolution and the origins of north american fringe-toed lizards. | fossil evidence suggests that extant north american lizard genera (north of mexico) evolved during the miocene. although fossils of the clade phrynosomatidae (spiny lizards and sand lizards) have been reported, there have been no previously described fossils of the fringe-toed sand lizards (uma). in the extant biota, uma inhabit arid deserts, and members of the western clade of uma are restricted to sand dunes or other habitats containing fine-grained sand. | 2019 | 31492110 |
