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.

Mycoplasma agassizii Multilocus Sequence Typing Using Nanopore Sequencing: Insights Into Genetic Diversity and Isolate Characterization. [PDF]

Ann N Y Acad Sci
ABSTRACT Mycoplasma agassizii (Mycoplasmopsis agassizii) is a major pathogen responsible for upper respiratory tract disease (URTD) in tortoises, contributing to worldwide population declines. Despite its significance, tools for strain‐level identification and epidemiological tracking remain limited.

Strong Signatures of Selection on Candidate Genes Underlying Core Speciation Mechanisms in Desert Tortoises. [PDF]

Mol Ecol Resour
ABSTRACT Genomic incompatibilities and differential ecological adaptation are thought to be fundamental mechanisms of speciation. In this study, we generated a chromosome‐scale reference genome and annotation for Gopherus morafkai , the Sonoran Desert tortoise, and conducted a detailed analysis of genes under positive selection with its sister species,

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

Shelter Distribution and Type Affect Space Use of a Desert Reptile. [PDF]

Ecol Evol
Animal home ranges derive from the distribution of resources across the landscape. We investigated effects of burrow distribution and availability on space use of the Sonoran Desert Tortoise (Gopherus morafkai) at two populations with different habitat structures to determine the extent to which habitat capacity is defined by factors subject to ...

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
