Raising the prospects for a forgotten fauna: a review of 10 years of conservation effort for New Zealand reptiles
Distribution and conservation of lizards in the Vizcaino Biosphere Reserve, Baja California Sur, Mexico
Ecological comparison of sympatric populations of sand lizards (Cophosaurus texanus and Callisaurus draconoides)
Sympatric populations of Cophosaurus texanus and Callisaurus draconoides were periodically sampled from March 1973 through April 1974 at Burro Creek, Mohave County, Arizona. Callisaurus were also sampled at Rock Valley, Nye County, Nevada. Sex ratios were skewed in favor of males in the adult Cophosaurus but were equal in both adult populations of Callisaurus. Both species became sexually mature as yearlings. Mean clutch sizes were 3.55 (+/- 0.83) for Cophosaurus, and 4.25 (+/- 1.08) and 5.07 (+/- 1.33) for Callisaurus at Burro Creek and Rock Valley respectively. Evidence of multiple clutches was exhibited by both species. Egg weight/body weight ratios for both species and clutch weight/body weight ratios for Cophosaurus...
Light and Electron Microscopic Evidence for Projections From the Thalamic Nucleus Rotundus to Targets in the Basal Ganglia, the Dorsal Ventricular Ridge, and the Amygdaloid Complex in a Lizard
Synopsis: The short-horned lizard is Alberta's only lizard. It is indigenous to semi-arid, short grass portions of the northern Great Plains and usually found in rather rough terrain. This report evaluated habitat suitability requirements for the short-horned lizard according to the following parameters: Topographical Features: Most of the daily movement patterns during the summer rarely exceeded 30m, and generally occurred along the slopes of the valleys or valley bottoms. Consequently, all valleys and all prairie habitat within 100m of valleys are considered the best potential habitat. Native Prairie Class: Native Prairie Class (NPC) is derived from the Native Prairie Vegetation Baseline Inventory developed...
In Vitro and in Vivo Cholinesterase Inhibition in Lacertids by Phosphonate- and Phosphorothioate-Type Organophosphates
Long-term effects of anthropogenic habitat disturbance on a lizard assemblage inhabiting coastal dunes in Argentina
We analyzed lizard assemblage structure as a function of elevation in the Bonneville Basin region of the Great Basin Desert using data from visual surveys performed between 2000 and 2003. A total of 1221 lizard observations were recorded, representing eight of the nine species known to occur in the Bonneville Basin. Individual species response curves showed Gaussian and truncated Gaussian distributions for most taxa, and most species demonstrated a nonrandom dispersion of occurrences along the elevation gradient. Nonmetric multidimensional scaling (NMS) revealed hierarchical structuring of lizard species, and strong correlation of NMS axes with elevation provided evidence of uniform lizard community assembly with...
This dataset includes location, field measurements, and descriptions of 330 Uma inornata sampled for the research study entitled “Sampling Across 20 Years (1996–2017) Reveals Loss of Diversity and Genetic Connectivity in the Coachella Valley Fringe-Toed Lizard (Uma inornata)”. Field sampling occurred between March and September of 2017 and between April and June of 2018. Lizards were located by visually searching dune habitat in all major populations. Sites included Windy Point, Willow Hole, Train Station, Whitewater, and the South Coachella Valley Preserve. In addition, satellite populations in the Indio Hills and individuals salvaged from Section 24 and translocated to Stebbin’s Dune were also sampled. Lizards...
