Origin of translocated animals is associated with time to settlement and post-translocation survival [PDF]

Movement Ecology
Translocation of animals is a widespread tool for resolving human-wildlife conflicts and augmenting struggling wild populations. However, expected time to settlement and survival (both measures of translocation success) are often unknown, particularly as

Indirect impacts of a highway on movement behavioral states of a threatened tortoise and implications for landscape connectivity [PDF]

Scientific Reports
Roads have often been identified as barriers to the movement of free-ranging animals. However, whether restoration of landscape connectivity across roadways can mitigate barriers to movement is insufficiently understood in light of indirect effects of ...

Body condition scoring facilitates healthcare monitoring in Hermann's Tortoises (Testudo hermanni ssp.). [PDF]

PLoS ONE
Clinical assessment of body condition is crucial in captive and free-ranging reptiles, since a large percentage of diseases result from inadequate nutrition.

OXALOSIS IN WILD DESERT TORTOISES, GOPHERUS AGASSIZII [PDF]

Journal of Wildlife Diseases, 2009
We necropsied a moribund, wild adult male desert tortoise (Gopherus agassizii) with clinical signs of respiratory disease and elevated plasma biochemical analytes indicative of renal disease (blood urea nitrogen [415 mg/dl], uric acid [11.8 mg/dl], sodium [>180 mmol/l] and chloride [139 mmol/l]). Moderate numbers of birefringent oxalate crystals, based

Variations in climate drive behavior and survival of small desert tortoises

Frontiers in Ecology and Evolution, 2023
In the Mojave Desert, timing and amounts of precipitation profoundly affect the availability of water and annual plant foods necessary for the threatened Agassiz’s desert tortoise (Gopherus agassizii) to survive, especially during prolonged droughts.

Co-infection does not predict disease signs in Gopherus tortoises [PDF]

Royal Society Open Science, 2017
In disease ecology, the host immune system interacts with environmental conditions and pathogen properties to affect the impact of disease on the host.

Captive Care of the Desert Tortoise, Gopherus agassizii [PDF]

Journal of Herpetological Medicine and Surgery, 2001
ABSTRACT The desert tortoise, Gopherus agassizii, is one of the more common species of tortoises seen by veterinarians practicing in the southwestern United States. Over the past century, many desert tortoises have been taken into captivity. It is currently illegal to remove these tortoises from the wild. Captive populations continue to grow as

High quality draft genome sequences of Mycoplasma agassizii strains PS6T and 723 isolated from Gopherus tortoises with upper respiratory tract disease

Standards in Genomic Sciences, 2018
Mycoplasma agassizii is one of the known causative agents of upper respiratory tract disease (URTD) in Mojave desert tortoises (Gopherus agassizii) and in gopher tortoises (Gopherus polyphemus). We sequenced the genomes of M. agassizii strains PS6T (ATCC

Predation on desert tortoises (Gopherus agassizii) by desert canids

Journal of Arid Environments, 2021
Desert tortoises (Gopherus agassizii) are a long-lived reptile vulnerable to predation by many predators, including desert kit foxes (Vulpes macrotis arsipus) and coyotes (Canis latrans). From 2009 to 2014, we assessed canid food habits at a study site in the Mojave Desert in California, USA, by collecting and analyzing desert kit fox and coyote scats.
