Respiratory Biology during Gravidity in Crotaphytus collaris and Gambelia wislizenii
—During gravidity lizards experience a striking decrease in lung volume as a result of lung compression by eggs growing within the body cavity. In order to understand the effect of this decrease in lung volume on the respiratory biology of gravid egg-laying lizards, we measured changes in total lung volume, resting and postexercise expired volume, minute volume, respiratory frequency, and carbo...
متن کاملImpact of fire management on the ecology of collared lizard (Crotaphytus collaris) populations living on the Ozark Plateau
Eastern collared lizards (Crotaphytus collaris collaris) on the Ozark Plateau of southern Missouri are restricted to islands of rocky glade habitat located throughout the oak–hickory forests of the region. Human mediated suppression of fire negatively impacts collared lizard populations by permitting the overgrowth and consequent disappearance of this glade habitat and also leads to a dense for...
متن کاملhemosensory Searching in Lizards: Their Absence in a Crotaphytid Lizard (Crotaphytus collaris) and a Proposal for Research in Zoos
Lizards in scleroglossan families of actively foraging carnivores and the herbivorous iguanids use the tongue to gather chemical samples to detect, identify, and locate food prior to attack, and to relocate lost food. In contrast, previously studied iguanian families other than Iguanidae lack lingually mediated prey chemical discrimination (PCD) and do not exhibit lingually mediated chemosensor...
متن کاملExtinction, reintroduction, and restoration of a lizard meta-population equilibrium in the Missouri Ozarks.
In this issue of Molecular Ecology, Neuwald & Templeton (2013) report on a 22-year study of natural populations of Collared Lizards (Crotaphytus collaris) that evolved on isolated on rock outcrops (‘glades’) in the Ozark Mountains in eastern Missouri. This ecosystem was originally maintained by frequent fires that kept the forest understory open, but fire-suppression was adopted as official pol...
متن کاملMitochondrial introgression and incomplete lineage sorting through space and time: phylogenetics of crotaphytid lizards.
We investigate the roles of mitochondrial introgression and incomplete lineage sorting during the phylogenetic history of crotaphytid lizards. Our Bayesian phylogenetic estimate for Crotaphytidae is based on analysis of mitochondrial DNA sequence data for 408 individuals representing the 12 extant species of Crotaphytus and Gambelia. The mitochondrial phylogeny disagrees in several respects wit...
