Prevalence and Diversity of the Upper Respiratory Pathogen Mycoplasma agassizii in Mojave Desert Tortoises (Gopherus agassizii)

Herpetologica, 2017
Abstract:  Upper respiratory tract disease (URTD), caused by Mycoplasma agassizii, has been deemed a threat to populations of Mojave Desert Tortoises, Gopherus agassizii. Previous work on URTD has focused on serology and visual health examinations to determine the extent of this disease in some natural tortoise populations.

A highway's road-effect zone for desert tortoises (Gopherus agassizii)

Journal of Arid Environments, 2006
Abstract Roads and highways can affect populations of animals directly (e.g. due to road mortality) and indirectly (e.g. due to fragmentation of habitat and proliferation of non-native or predatory species). We investigated the effect of roads on threatened desert tortoise ( Gopherus agassizii ) populations in the Mojave Desert, California, and ...

Long-Term Sperm Storage in the Desert Tortoise (Gopherus agassizii)

Copeia, 1998
Many reptilian species exhibit the ability to store sperm in the female reproductive tract for extended periods of time (Gist and Jones, 1987; Birkhead and Moller, 1993). Sperm storage may be used to separate reproductive events such as copulation, fertilization, and hatching to optimize timing of these events (Birkhead and Moller, 1993).

Clarithromycin pharmacokinetics in the desert tortoise (Gopherus agassizii).

Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians, 1999
Clarithromycin is a new, safe orally administered macrolide antibiotic active against Mycoplasma sp. in humans. Single-dose and multidose pharmacokinetic parameters were determined for clarithromycin in wild-caught desert tortoises (Gopherus agassizii) seropositive for M. agassizii. Clarithromycin blood levels were measured in three tortoises for up to

MYCOPLASMA AGASSIZIIIN MORAFKA'S DESERT TORTOISE (GOPHERUS MORAFKAI) IN MEXICO

Journal of Wildlife Diseases, 2015
We conducted health evaluations of 69 wild and 22 captive Morafka's desert tortoises (Gopherus morafkai) in Mexico between 2005 and 2008. The wild tortoises were from 11 sites in the states of Sonora and Sinaloa, and the captive tortoises were from the state-managed Centro Ecológico de Sonora Zoo in Hermosillo and a private residence in the town of ...

Sevoflurane anesthesia in desert tortoises (Gopherus agassizii).

Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians, 1999
The effects of sevoflurane on anesthesia induction, recovery, ventricular pressures, heart rate, ventricular pH, blood gas values, and electrolytes were evaluated in desert tortoises (Gopherus agassizii). Tortoises were orotracheally intubated while awake and ventilated manually with 3-7% sevoflurane in oxygen (1 L/min) to achieve desired expired ...

Morphologic and cytochemical characteristics of blood cells from the desert tortoise (Gopherus agassizii)

American Journal of Veterinary Research, 1992
SUMMARY Morphologic and cytochemical staining characteristics of erythrocytes, leukocytes, and thrombocytes of the desert tortoise (Gopherus agassizii) were evaluated, using blood smears prepared from 23 healthy tortoises of Kern County, Calif. Special emphasis was placed on differentiating features of the various leukocytes and thrombocytes. A variety

Surgical Treatment of a Carapacial Osteosarcoma in a Desert Tortoise (Gopherus agassizii)

Journal of Herpetological Medicine and Surgery
Abstract An 80-year-old, 5.6 kg male intact desert tortoise (Gopherus agassizii) was presented for evaluation of an extensive mass protruding from the ventral margin between the supracaudal scutes of the carapace and anal scutes of the plastron.

Polyandry and multiple paternities in the threatened Agassiz’s desert tortoise, Gopherus agassizii

Conservation Genetics, 2011
We used data from 17 to 20 microsatellite markers to investigate the incidence of multiple paternities in wild Agassiz’s desert tortoises, Gopherus agassizii. Neonates were sampled from clutches of eggs laid by wild mothers in nesting enclosures at Edwards Air Force Base and at the Marine Corps Air Ground Combat Center, California.

Ecological Energetics of the Desert Tortoise (Gopherus Agassizii): Effects of Rainfall and Drought

Ecology, 1996
To elucidate ecological effects of variation in the temporal distribution of a limiting resource (water in the Mojave Desert), energetics of two free—living populations of desert tortoises (Gopherus [Xerobates] agassizii) were studied concurrently over 18 mo with use of doubly—labeled water. Field metabolic rates (FMR) and feeding rates (estimated from
