Introduction to the special issue on the changing Mojave Desert Introduction to the special issue on the changing Mojave Desert
The Mojave Desert, which lies between the Great Basin Desert in the north and the Sonoran Desert in the south, covers an estimated 114 478–130 464 km2 of the south-western United States and includes parts of the states of Nevada, Utah, Arizona, and California, with the amount of land mass dependent on the definition (Fig. 1; Rowlands et al., 1982; McNab and Avers, 1994; Bailey, 1995...

Abundance and distribution of selected elements in soils, stream sediments, and selected forage plants from desert tortoise habitats in the Mojave and Colorado deserts, USA Abundance and distribution of selected elements in soils, stream sediments, and selected forage plants from desert tortoise habitats in the Mojave and Colorado deserts, USA
A baseline and background chemical survey was conducted in southeastern California, USA, to identify potential sources of toxicants in natural and anthropogenically-altered habitats of the threatened desert tortoise (Gopherus agassizii). Soil, stream sediment, and plant samples were collected from six tortoise habitat study areas in the Mojave and Colorado deserts and analysed for up to...

Attributes of desert tortoise populations at the National Training Center, Central Mojave Desert, California, USA Attributes of desert tortoise populations at the National Training Center, Central Mojave Desert, California, USA
We sampled 21 study plots for desert tortoises (Gopherus agassizii) at the National Training Center, Fort Irwin, California. Each plot was sampled once between 1997 and 2003 to obtain a snapshot of population attributes, status, and relationships between tortoise densities and human activities. Densities ranged from

Effects of livestock watering sites on alien and native plants in the Mojave Desert, USA Effects of livestock watering sites on alien and native plants in the Mojave Desert, USA
Increased livestock densities near artificial watering sites create disturbance gradients called piospheres. We studied responses of alien and native annual plants and native perennial plants within 9 piospheres in the Mojave Desert of North America. Absolute and proportional cover of alien annual plants increased with proximity to watering sites, whereas cover and species richness of...

Laser ablation ICP-MS profiling and semiquantitative determination of trace element concentrations in desert torotise shells: Documenting the uptake of elemental toxicants Laser ablation ICP-MS profiling and semiquantitative determination of trace element concentrations in desert torotise shells: Documenting the uptake of elemental toxicants
The outer keratin layer (scute) of desert tortoise shells consists of incrementally grown laminae in which various bioaccumulated trace elements are sequestered during scute deposition. Laser ablation ICP-MS examination of laminae in scutes of dead tortoises revealed patterns of trace elemental distribution from which the chronology of elemental uptake can be inferred. These patterns may...

Clinical disease and laboratory abnormalities in free-ranging desert tortoises in California (1990-1995) Clinical disease and laboratory abnormalities in free-ranging desert tortoises in California (1990-1995)
Desert tortoise (Gopherus agassizii) populations have experienced precipitous declines resulting from the cumulative impact of habitat loss and human and disease-related mortality. Diagnosis of disease in live, free-ranging tortoises is facilitated by evaluation of clinical signs and laboratory test results but may be complicated by seasonal and environmental effects. The goals of this...

Guidelines for the field evaluation of desert tortoise health and disease Guidelines for the field evaluation of desert tortoise health and disease
Field evaluation of free-ranging wildlife requires the systematic documentation of a variety of environmental conditions and individual parameters of health and disease, particularly in the case of rare or endangered species. In addition, defined criteria are needed for the humane salvage of ill or dying animals. The purpose of this paper is to describe, in detail, the preparation...
