Abstract Survival of adult Desert Tortoises (Gopherus agassizii) appears related to site-specific variation in precipitation and productivity of annual plants. [] Key Method Survival rates were initially derived from population surveys conducted over a three-year period and by radio-telemetry monitoring over a seven-year period beginning in 1994. After a period of initial stability, survival rates on the two sites diverged over the study period, and seven-year survival rates estimated from radio-telemetry…
Climatic variation and tortoise survival: has a desert species met its match?
Head-started Agassiz’s desert tortoises Gopherus agassizii achieved high survival, growth, and body condition in natural field enclosures
TLDR
Improvements in predator control, food and water supplementation and pen structure increased survival from seven to 10 times that under wild conditions, and head-starting methods can greatly improve juvenile survivorship, and increase numbers of hard-shelled, midsized juveniles to help augment wild populations.
Long-Term Post-Fire Effects on Spatial Ecology and Reproductive Output of Female Agassiz’s Desert Tortoises (Gopherus agassizii) at a Wind Energy Facility near Palm Springs, California, USA
We studied the long-term response of a cohort of eight female Agassiz’s desert tortoises (Gopherus agassizii) during the first 15 years following a large fire at a wind energy generation facility
Structure and Dynamics of a Namaqualand Speckled Tortoise (Homopus signatus signatus) Population over 5 Years of Rainfall Variation
TLDR
Mortality during current, periodic droughts does not seem to oppose recommended conservation measures to improve adult survival and delay detrimental effects of aridification on growth and reproduction, and physiological responses to drought exploited by H. s.

Survivorship in Two Coastal Populations of Gopherus berlandieri
TLDR
Abundance of prickly pear (Opuntia engelmannii), on which tortoises feed, on the Yturria Ranch may have contributed to a higher survivorship by providing high water content biomass during droughts and by providing cover that reduced predation.
Seasonal Variation in Survivorship and Mortality of Desert Tortoises in the Sonoran Desert, Arizona
Abstract We determined annual survivorship and causes of mortality at two Desert Tortoise, Gopherus agassizii, study sites in the Sonoran Desert, Arizona, based on radio-telemetry data. Annual
Severe mortality of a population of threatened Agassiz’s desert tortoises: the American badger as a potential predator
TLDR
The American badger is discussed as a plausible predator of a local tortoise population, but further investigation into these events and the impacts such mortality can have on tortoise persistence are recommended.
Home range and movement of desert tortoises Gopherus agassizii in the Mojave Desert of California, USA
Radio telemetry of 29 desert tortoises Gopherus agassizii in 2000 and 60 in 2001 at 4 sites in the Mojave Desert of California, USA, revealed that males had larger home ranges and moved greater

Effects of drought on desert tortoise movement and activity
TLDR
Differences in levels of winter precipitation between years and the resulting variation of winter annual biomass in the spring appear to play a significant role in desert tortoise movement and activity patterns.
ECOLOGICAL ENERGETICS OF THE DESERT TORTOISE (GOPHERUS AGASSIZII): EFFECTS OF RAINFALL AND DROUGHT'
TLDR
Energy acquisition and expenditure in desert tortoises are thus strongly constrained by the contingencies of rainfall, both indirectly through effects on availability and quality of food, and directly through reliance on free-standing water for drinking, which is apparently necessary for achieving a net annual energy profit.
Reproduction and survival of the desert tortoise (Scaptochelys agassizii) in Ivanpah Valley, California
TLDR
Analyses of tortoise feces showed that grasses were eaten with equal frequency until mid-May in both years, but that after this time grasses essentially disappeared from 1981 diets, which may partially explain the egg production in 1981-one of the most unfavorable years on record in the Mojave Desert.
Modeling Population Viability for the Desert Tortoise in the Western Mojave Desert
TLDR
It is found that the rate of population growth is most sensitive to the survival of large adult females and that improving survival of this size class to reputably "pristine" rates could reverse population declines; in contrast, large improvements in other vital rates will not, alone, reverse population decline.
Phenological Events and Their Environmental Triggers in Mojave Desert Ecosystems
Phenological events in Mojave desert systems are triggered by heavy rains (>25 mm [1 in]). The most predictable and consequential of these is a regional rain between late September and early
Effects of climatic variation on field metabolism and water relations of desert tortoises
TLDR
The physiological and behavioral flexibility of desert tortoises, evident in individuals living at all three study sites, appears central to their ability to survive droughts and benefit from periods of resource abundance.
DRINKING AND CONSTRUCTION OF WATER CATCHMENTS BY THE DESERT TORTOISE, GOPHERUS AGASSIZII, IN THE MOJAVE DESERT
Desert tortoises, Gopherus agassizii, generally were active in the spring and fall. They often became active during and after infrequent showers and thunderstorms, and drank from temporary pools of
Physiological ecology of desert tortoises in southern Nevada
TLDR
Tortoises apparently relinquish maintenance of internal homeostasis on a daily basis during most of the year, while tolerating large imbalances in their water, energy and salt budgets.
Anhomeostasis: Seasonal Water and Solute Relations in Two Populations of the Desert Tortoise (Gopherus agassizii) during Chronic Drought
TLDR
Seasonal patterns of osmoregulation and water balance were compared in two populations of the desert tortoise inhabiting portions of the Mojave Desert with different seasonal rainfall patterns, resulting in wide, behaviorally based variation among individuals in all variables measured.
