Accurate abundance estimates of plant populations are fundamental to numerous ecological questions and for conservation. Estimating population parameters for rare or cryptic plant species, however, can be challenging and thus developing and testing n

We studied the plant resource use between and within populations of desert tortoise (Gopherus agassizii) across a precipitation gradient in the Sonoran Desert of Arizona. The carbon and nitrogen stable isotope values in animal tissues are a reflectio

Individual lizard species may reduce competition within a habitat by diverging along one or more niche dimensions, such as spatial, temporal or dietary dimensions. We compared the morphology, activity patterns, microhabitat characteristics, thermal b

Geckos of the genus Rhoptropus are small diurnal lizards occurring in arid regions of Namibia and Angola, and are not well studied relative to other desert lizards. Rhoptropus afer has a field metabolic rate significantly lower than that of other des

The heterogeneous topography of the Great Basin province leads to one of the most climatically variable regions in the Northern Hemisphere. Along the southwestern edge lies Death Valley, an area of even more extreme climate and physiographic relief;

Many ungulates, including wildebeest, seek shade and orient their bodies relative to incoming solar radiation in order to reduce environmental heat loads. Blue (Connochaetes taurinus) and black wildebeest (Connochaetes gnou), which co-exist artificia

Flat lizards of the genus Platysaurus are primarily insectivorous, but some species are omnivorous, eating significant amounts of plant material. The common flat lizard, P. intermedius, is thought to forage on arthropods, flowers, leaves and fruit. H

We used stable isotopes of carbon and nitrogen to study the trophic niche of two species of insectivorous lizards, the Husab sand lizard Pedioplanis husabensis and Bradfield's Namib day gecko living sympatrically in the Namib Desert. We measured the

Death Valley, California is today the hottest hyperarid area in the western Hemisphere with temperatures of 57 °C (134 °F) recorded. During the late Quaternary, pluvial Lake Manly covered much of the Valley and contributed to a much more moderate c
