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, procedures, and

Mourning dove productivity in California during 1992-95: Was it sufficient to balance mortality?
Mourning dove (Zenaida macroura) populations have declined steadily in the western United States since 1966. We investigated the role of recruitment in this long-term problem by studying nesting ecology of mourning doves from March to September 1992-95, in the northern Central Valley, California, USA. We studied nesting doves in blue oak woodlands (Quercus douglasii), willow-cottonwood riparian ha

The Foraging Ecology of Royal and Sandwich Terns in North Carolina, USA
Population sizes of territorial male red-winged blackbirds (Agelaius phoeniceus) were determined with counts of territorial males (area count) and a Petersen-Lincoln Index method for roadsides (roadside estimate). Weather conditions and time of day did not influence either method. Combined roadside estimates had smaller error bounds than the individual transect estimates and were not hindered by

Release from parasites as natural enemies: increased performance of a globally introduced marine crab
Introduced species often seem to perform better than conspecifics in their native range. This is apparent in the high densities they may achieve or the larger individual sizes they attain. A prominent hypothesis explaining the success of introduced terrestrial species is that they are typically free of or are less affected by the natural enemies (competitors, predators, and parasites) they encount

Restoring fire to wilderness: Sequoia and Kings Canyon National Parks
Sequoia and Kings Canyon National Parks, established in 1890, consist of 863,741 acres (349,551 ha) of Sierra Nevada foothills, mid-elevation conifer forest, and high-elevation alpine environment. The parks contain 36 giant sequoia (Sequoiadendron giganteum) groves, including the largest known tree, the General Sherman. Ninety-four percent of the parklands is in designated or proposed wilderness (

Integration of genotoxicity and population genetic analyses in kangaroo rats (Dipodomys merriami) exposed to radionuclide contamination at the Nevada Test Site, USA
We examined effects of radionuclide exposure at two atomic blast sites on kangaroo rats (Dipodomys merriami) at the Nevada Test Site, Nevada, USA, using genotoxicity and population genetic analyses. We assessed chromosome damage by micronucleus and flow cytometric assays and genetic variation by randomly amplified polymorphic DNA (RAPD) and mitochondrial DNA (mtDNA) analyses. The RAPD analysis sho
