Testosterone identifies hatchling sex for Mojave desert tortoises (Gopherus agassizii) [PDF]
Scientific Reports, 2023 The threatened Mojave desert tortoise (Gopherus agassizii) exhibits temperature-dependent sex determination, and individuals appear externally sexually monomorphic until sexual maturity.

Cutaneous adenocarcinoma in a desert tortoise ( Gopherus agassizii )
International Journal of Veterinary Science and Medicine, 2013 This report describes the clinical and histopathological findings of a rare case of cutaneous adenocarcinoma in a 40-year-old desert tortoise. Surgical excision of the neoplasm improved the general health condition and locomotion of the tortoise although

Desert tortoise (Gopherus agassizii) dietary specialization decreases across a precipitation gradient. [PDF]
PLoS ONE, 2013 We studied the plant resource use between and within populations of desert tortoise (Gopherus agassizii) across a precipitation gradient in the Sonoran Desert of Arizona. The carbon and nitrogen stable isotope values in animal tissues are a reflection of

Range‐wide occupancy trends for the Mojave desert tortoise (Gopherus agassizii)
Ecosphere, 2023 Data from long‐term monitoring programs, such as the US Fish and Wildlife Service (USFWS) line distance sampling (LDS) program for Mojave desert tortoises (Gopherus agassizii), are increasingly being used in new ways to elucidate trends in population ...

Surveillance of Mycoplasma agassizii in Texas tortoises (Gopherus berlandieri) for translocation with emphasis on treatment and recovery [PDF]
Frontiers in Veterinary ScienceBackgroundTexas tortoises (Gopherus berlandieri) are a Texas-state threatened species. Translocation is often suggested as a mitigation option; however, disease status and the potential for spread must be considered prior to such efforts.

Move it or lose it: Predicted effects of culverts and population density on Mojave desert tortoise (Gopherus agassizii) connectivity [PDF]
PLoS ONE, 2023 Roadways and railways can reduce wildlife movements across landscapes, negatively impacting population connectivity. Connectivity may be improved by structures that allow safe passage across linear barriers, but connectivity could be adversely influenced

Immune and sex-biased gene expression in the threatened Mojave desert tortoise, Gopherus agassizii. [PDF]
PLoS ONE, 2020 The immune system of ectotherms, particularly non-avian reptiles, remains poorly characterized regarding the genes involved in immune function, and their function in wild populations.

The dazed and confused identity of Agassiz’s land tortoise, Gopherus agassizii (Testudines: Testudinidae) with the description of a new species and its consequences for conservation [PDF]
ZooKeys, 2011 We investigate a cornucopia of problems associated with the identity of the desert tortoise, Gopherus agassizii Cooper. The date of publication is found to be 1861, rather than 1863.

Mycoplasma agassizii, an opportunistic pathogen of tortoises, shows very little genetic variation across the Mojave and Sonoran Deserts. [PDF]
PLoS ONE, 2021 Mycoplasma agassizii is a common cause of upper respiratory tract disease in Mojave desert tortoises (Gopherus agassizii). So far, only two strains of this bacterium have been sequenced, and very little is known about its patterns of genetic diversity ...

Desert tortoises (Gopherus agassizii) are selective herbivores that track the flowering phenology of their preferred food plants. [PDF]
PLoS ONE, 2015 Previous studies of desert tortoise foraging ecology in the western Mojave Desert suggest that these animals are selective herbivores, which alter their diet according to the temporal availability of preferred food plants. These studies, however, did not
