Dominance and environmental correlates of alien annual plants in the Mojave Desert, USA
Land managers are concerned about the negative effects of alien annual plants on native plants, threatened and endangered species such as the desert tortoise (Gopherus agassizii), and ecosystem integrity in the Mojave Desert. Management of alien plants is hampered by a lack of information regarding the dominance and environmental correlates of these species. The results of this study indicate thatAuthorsM.L. Brooks, K.H. BerryEffects 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 native annuaAuthorsM.L. Brooks, J.R. Matchett, K.H. BerryLaser 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 be of patAuthorsM. D. Seltzer, Kristin H. BerryClinical 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 study were:AuthorsMary M. Christopher, Kristin H. Berry, Brian T. Henen, Kenneth A. NagySpring wildflowers spectacular in 2003 at the Desert Tortoise Natural Area

Objectives - To characterize protein composition of shell scute of desert tortoises and to determine whether detectable differences could be used to identify healthy tortoises from tortoises with certain illnesses. Animals - 20 desert tortoises. Procedures - Complete postmortem examinations were performed on all tortoises. Plastron scute proteins were solubilized, scute proteins were separated byAuthorsB.L. Homer, C. Li, K.H. Berry, N. D. Denslow, E.R. Jacobson, R.H. Sawyer, J.E. WilliamsGuidelines 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, procedures, andAuthorsKristin H.

This report presents a map showing the potentiometric surface of the Upper Patapsco aquifer in the Patapsco Formation of Cretaceous age in Southern Maryland during September 1999. The map is based on water-level measurements in 49 wells. The potentiometric surface was 119 feet above sea level near the northern boundary and outcrop area of the aquifer in a topographically high area of Anne ArundelAuthorsRobert H. Webb, Diane E.
