“…Dipodomvs merriami and Perognathus amplus. the most common species in the study areas, do not differ significantly in the types of seeds they ingest or their frequency Df ingestion (Reichman, 1975), but they do differ in the manner in which they forage for seeds. Pocket mice "filter feed" continuously, methodically searching a small area for individual seeds.…”

“…Thus, rainy seasons and the blooms of annuals associated with them regulate the onset of the breeding season (Chew and Butterworth, 1964;Van de Graaff and Balda, 1973). There is some speculation that plants provide Dipodomys with the steroid hormones that trigger breeding (Chew and Butterworth, 1964;Reichman, 1975). Insects can comprise up to 15% of the diet of D. merriami (Reichman, 1975).…”

“…Up to six species of heteromyid rodents have been reported on a study site (Brown, 1973), and four to five species on a site is not unusual (Rosenzweig and Winakur, 1969;Reichman, 1975;Hallett, 1982). All species of heteromyids are predominantly granivorous, and thus rely on the same resource for survival.…”

PERFORMING ORGANIZATION NAME(S) AND ADDRESS(ES)Hubbs 12b. DISTRIBUTION CODE ABSTRACT (Maximum 200 words)There has been public concern that wildlife could be affected by military training activities. Of particular interest was the hypothesis that noise from military aircraft would disrupt the ecological balance between predator and prey by giving one or the other an advantage. To gauge these effects, this study was conducted under an Air Force Range in an area receiving levels of exposure higher than normally encountered under a Military Training Route. A nearby control site was exposed to much lower levels of noise. Noise monitors recorded actual exposure, and hearing of one heteromyid species, the kangaroo rat, was measured in situ. A total of 14,455 trap-nights were spent monitoring nocturnal small mammal communities on exposed and control plots. Rodent species diversity, numbers, reproductive activity, recruitment, mean weights, and survival were measured. The kit fox, a predator, was also examined. Although differences were uncovered between kit fox and smal mammal populations between the control and exposed areas, none was large, and none was at odds with the most parsimonious natural explanations. If the effects observed are assumed to be the result of aircraft noise exposure, the consequences to rodents and fox populations were smaller in magnitude than the natural variability observed during the course of the study.14.

“…In New Mexico, Findley and others (1975) describe the Bailey's pocket mouse as inhabiting "xeric brushy hillsides." In Arizona the species occurs in Chihuahuan Desert plant communities and in saguaro-palo verde associations of the Sonoran Desert Reichman 1975). Habitat is characterized by relatively sparse grass cover, with grasses interspersed with open ground and with shrubs (GP 2001e).…”

Assessment of native species and ungulate grazing in the Southwest: Terrestrial wildlife

______________________________________Range managers in the Southwestern States are increasingly being required to develop management strategies that take into consideration the conservation of wildlife populations. However, information on many aspects of the fundamental biology and impacts of grazing on individual species is still lacking in the scientific and government literature. This report documents a project designed to assemble this information for terrestrial wildlife in Arizona and New Mexico that have the potential to be negatively impacted by grazing or range management practices. To achieve this, a two-stage panel process was developed that employed a variety of wildlife experts to create a list of potentially vulnerable species and to develop an informational database. Panelists first reviewed and assessed all terrestrial vertebrates in the region to develop an initial list. In the second stage, the panelists refined the list, reviewed published information drafted into individual species accounts, and then augmented these accounts with information from their own experience and observations. The resulting database contains accounts for 305 species and subspecies of amphibians, reptiles, birds and mammals, including a computer database that allows managers to search and query the species accounts based on geographic distribution as well as shared ecological and life history characteristics.

Frequency‐dependent seed predation by rodents on Sonoran Desert winter annual plants

Abstract. Numerous mechanisms may allow species to coexist. We tested for frequencydependent predation, a mechanism predicted by theory and established as a foraging behavior for many types of animals. Our field test included multiple prey species exposed in situ to multiple predator species and individuals to determine whether the prey species experienced predation patterns that were frequency dependent. The prey were seeds of three species of Sonoran Desert winter annual plants while the predator species were a guild of nocturnal seed foraging heteromyid and murid rodents that co-occur naturally in the same community as the desert annuals at Tumamoc Hill near Tucson. Seeds of one species were much preferred over the other two. Nonetheless, we found the net effect of rodent foraging to be positively frequency dependent (the preference for each species is higher when it is common than when it is uncommon) as has been previously hypothesized. This frequency-dependent predation should function as a species coexistence promoting mechanism in concert with the storage effect that has been previously demonstrated for this system.
