(August 2012) Drew Edwin Dittmer, B.S., University of Missouri-Columbia Co-Chairs of Advisory Committee: Dr. Toby J. Hibbitts Dr. Lee A. Fitzgerald The Fence Lizard (Sceloporus undulatus complex) is a wide ranging North American species complex occurring from the eastern seaboard westward through the great plains and central Rocky Mountains and into the American Southwest. A recent phylogeny suggests four species lineages occur within S. undulatus. Traits within an interbreeding species that are influenced by sexual selection are under different selection pressures and may evolve independently from the selective forces of habitat. Sceloporus lizards have several characters that are influenced by sexual selection. I investigated sexual size dimorphism and allometric relationships of body size (snout vent length), torso length, rear leg length and three measurements of head size in 12 populations from the four species in the S. -

Intelligence of Bearded Dragons Submitted in partial fulfillment of the requirements for the Murray State University Honors Diploma Sydney Herndon 04/2021 i Abstract The purpose of this thesis is to study and explain the intelligence of bearded dragons. Bearded dragons (Pogona spp.) are a species of reptile that have been popular in recent years as pets. Until recently, not much was known about their intelligence levels due to lack of appropriate research and studies on the species. Scientists have been studying the physical and social characteristics of bearded dragons to determine if they possess a higher intelligence than previously thought. One adaptation that makes bearded dragons unique is how they respond to heat. Bearded dragons optimize their metabolic functions through a narrow range of body temperatures that are maintained through thermoregulation. Many of their behaviors are temperature dependent, such as their speed when moving and their food response. When they are cold, these behaviors decrease due to their lower body temperature. -
Niche Modeling for the Genus Pogona (Squamata: Agamidae) in Australia: Predicting Past (Late Quaternary) and Future (2070) Areas of Suitable Habitat
Niche modeling for the genus Pogona (Squamata: Agamidae) in Australia: predicting past (late Quaternary) and future (2070) areas of suitable habitat Julie E. Rej1,2 and T. Andrew Joyner2 1 Department of Wildlife Ecology, The Wilds, Cumberland, OH, USA 2 Department of Geosciences, East Tennessee State University, Johnson City, TN, USA ABSTRACT Background: As the climate warms, many species of reptiles are at risk of habitat loss and ultimately extinction. Locations of suitable habitat in the past, present, and future were modeled for several lizard species using MaxEnt, incorporating climatic variables related to temperature and precipitation. In this study, we predict where there is currently suitable habitat for the genus Pogona and potential shifts in habitat suitability in the past and future. Methods: Georeferenced occurrence records were obtained from the Global Biodiversity Information Facility, climate variables (describing temperature and precipitation) were obtained from WorldClim, and a vegetation index was obtained from AVHRR satellite data. Matching climate variables were downloaded for three different past time periods (mid-Holocene, Last Glacial Maximum, and Last Interglacial) and two different future projections representative concentration pathways (RCPs 2.6 and 8.5). MaxEnt produced accuracy metrics, response curves, and probability surfaces. For each species, parameters were adjusted for the best possible output that was biologically informative. Results: Model results predicted that in the past, there was little suitable habitat for P. henrylawsoni and P. microlepidota within the areas of their current range. Past areas of suitable habitat for P. barbata were predicted to be similar to the current 16 March 2018 Submitted prediction. Pogona minor and P. -

Biologic Environmental Survey, 24–26 Wickham St, East Perth, Western Australia 6004, Australia. Email: [email protected] ABSTRACT – The Western Australian Museum holds a vast collection of specimens representing a large portion of the 106 currently recognised taxa of dragon lizards (family Agamidae) known to occur across Australia. While the museum’s collection is dominated by Western Australian species, it also contains a selection of specimens from localities in other Australian states and a small selection from outside of Australia. Currently the museum’s collection contains 18,914 agamid specimens representing 89 of the 106 currently recognised taxa from across Australia and 27 from outside of Australia. This includes 824 type specimens representing 45 currently recognised taxa and three synonymised taxa, comprising 43 holotypes, three syntypes and 779 paratypes. Of the paratypes, a total of 43 specimens have been gifted to other collections, disposed or could not be located and are considered lost. An annotated catalogue is provided for all agamid type material currently and previously maintained in the herpetological collection of the Western Australian Museum. KEYWORDS: type specimens, holotype, syntype, paratype, dragon lizard, nomenclature. INTRODUCTION Australia was named by John Edward Gray in 1825, The Agamidae, commonly referred to as dragon Clamydosaurus kingii Gray, 1825 [now Chlamydosaurus lizards, comprises over 480 taxa worldwide, occurring kingii (Gray, 1825)]. -

Natural History Notes 435
NATURAL HISTORY NOTES 435 it exploits woody debris and bank vegetation as cover (Scott and Angermeier 1998, op. cit.). This would place it in close proximity to invertebrates and vertebrates that perch on branches, sticks, roots, and tree trunks. The present study adds further evidence that the putative chemical defense of P. fasciatus failed to protect the skink from predation from another group of vertebrates. Clearly the tail did not inhibit consumption by Micropterus henshalli, nor did the capacity of the skink to autotomize its tail as a predator diversion tactic. In all likelihood, the skink was ambushed by the bass and loss of the tail would have come too late to serve as an effective diversion as it might have against more visual predators such as birds and small mammals.

Evolution of Reptiles
Evolution of Reptiles: Reptiles were 1st vertebrates to make a complete transition to life on land (more food & space) Arose from ancestral reptile group called cotylosaurs (small, lizard like reptile) Cotylosaurs adapted to other environments in Permian period 1. Pterosaurs – flying reptiles 2. Ichthyosaurs & plesiosaurs – marine reptiles 3. Thecodonts – small, land reptiles that walked on back legs Mesozoic Era called “age of reptiles” Dinosaurs dominated life on land for 160 million years Brachiosaurs were largest dinosaurs Herbivores included Brontosaurus & Diplodocus, while Tyrannosaurus were carnivores Dinosaurs became extinct at end of Cretaceous period Mass extinction of many animal species possibly due to impact of huge asteroid with earth; Asteroid Impact Theory Amniote (shelled) egg allowed reptiles to live & reproduce on land Amniote Egg: Egg had protective membranes & porous shell enclosing the embryo Has 4 specialized membranes — amnion, yolk sac, allantois, & chorion Amnion is a thin membrane surrounding a salty fluid in which the embryo “floats” Yolk sac encloses the yolk or protein-rich food supply for embryo Allantois stores nitrogenous wastes made by embryo until egg hatches Chorion lines the inside of the shell & regulates oxygen & carbon dioxide exchange Shell leathery & waterproof Internal fertilization occurs in female before shell is formed Terrestrial Adaptations: Dry, watertight skin covered by scales made of a protein called keratin to prevent desiccation (water loss) Toes with claws to -

More than 62,000 vertebrate species have been identified. The vertebrate species now living represent only a small portion of the vertebrates that have existed. The best-known extinct vertebrates are the dinosaurs, a unique group of reptiles, which reached sizes not seen before or after in terrestrial animals. They were the dominant terrestrial animals for 150 million years, until they died out in a mass extinction near the end of the Cretaceous period. Although it is not known with certainty what caused their extinction, a great deal is known about the anatomy of the dinosaurs, given the preservation of skeletal elements in the fossil record. Currently, a number of vertebrate species face extinction primarily due to habitat loss and pollution. According to the International Union for the Conservation of Nature, more than 6,000 vertebrate species are classified as threatened. Amphibians and mammals are the classes with the greatest percentage of threatened species, with 29 percent of all amphibians and 21 percent of all mammals classified as threatened.
