Population densities, reproduction, and survival of the lizard Uta stansburiana were measured at the Nevada Test Site in southern Nevada, USA, between 1964 and 1974. These data were used to develop a model of the population dynamics of this species. Results of irrigation experiments in 0.4-ha enclosures near Mercury, Nevada, were used to formulate multiple-regression equations predicting frequency and size of clutches laid by two age-classes of females in terms of winter rainfall, March air temperatures, and Uta population density. Densities of Uta in these enclosures were manipulated, and age-specific survival modeled in terms of spring densities of Uta. Experiments in which an important predator on Uta (the leopard lizard, Crotaphytus wislizeni) was removed from enclosures were used to estimate the influence of the predator on basic survival rates of hatchling and older Uta. The model was generally developed from data acquired in the small enclosures, but predictions were compared with actual observations of changes in Uta populations in Rock Valley (19 km west of Mercury, Nevada) between 1966 and 1972.Agreement between model predictions and actual numbers was fair. The model predicted a decrease in density from 1966 to 1967, but numbers of Uta actually increased conspicuously at this time. This was the only major discrepancy between predictions and observations. The observed mean spring density (d) between 1967 and 1972 was 41.4 Uta/ha (SD = 20.8), while the model predicted a mean density of 37.8 Uta/ha (SD = 13.6). Observed and predicted mean proportions of yearlings in spring populations were identical (0.78).The basic version of the model estimated different survival rates for two age-groups of adult Uta. A simpler version of the model, using a common survival rate for both age-groups, gave predictions essentially identical with those of the basic model. Other tests of the basic model showed it to be most sensitive to changes in winter rainfall and predation pressure, much less so to air temperatures. Fifteenand 30-yr synthetic sequences of predator densities were used to examine model stability over longer periods of time. When predator densities were drawn randomly from distributions with a mean of 2 individuals/ha, model populations exhibited lower mean numbers and amplitudes than actually observed during 9 yr in Rock Valley.The basic model included three density-dependent parameters: clutch frequency, clutch size, and adult survival. The model was modified so that (1) egg production was density independent, while adult survival was not; (2...

Precipitation history and ecosystem response to multidecadal precipitation variability in the Mojave Desert region, 1893–2001

“…She documented substantial germination following rainfall events X 25 mm that occurred between late September and early December. Turner et al (1982) irrigated seasonally to verify Beatley's model, applying 50 mm of water (2 treatments of 25 mm each) in both the fall of 1969 and the fall of 1971. Annual production increased from 8 g/m 2 compared with 0.5 g/m 2 in the control plot in 1970 and 5 g/m 2 compared with 0.1 g/m 2 in 1972.…”

Precipitation quantity and timing affect native plant production and growth of a key herbivore, the desert tortoise, in the Mojave Desert

“…Abundant winter rainfall is linked to growth and reproduction in many vertebrates of southwestern North American, including rodents, lizards, and tortoises [9,14,15]. Arid-adapted animals can supplement their water intake by foraging on plants [16,17], but germination of winter annuals also depends on adequate winter precipitation [18].…”

“…The most significant environmental factor on side-blotched lizard egg production is winter rainfall (Turner et al 1982). Increased rainfall results in increased production of annual plants which, In turn, leads to a greater insect prey resource (Turner et al 1982). Parker and Pianka (1975) and Worthington (i982) found the same relationship to be true.…”

“…This variable is intended to relate directly to abundance of arthropods which are the side-blotched lizard's primary prey. The most significant environmental factor on side-blotched lizard egg production is winter rainfall (Turner et al 1982). Increased rainfall results in increased production of annual plants which, In turn, leads to a greater insect prey resource (Turner et al 1982).…”
