Mycoplasma agassizii in Morafka's desert tortoise (Gopherus morafkai) in Mexico.
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 Alamos. We tested 88 tortoises for mycoplasmal...
متن کاملIs Gopherus agassizii a Desert-Adapted Tortoise, or an Exaptive Opportunist? Implications for Tortoise Conservation
– The desert tortoise (Gopherus agassizii) has traditionally been viewed as an archetypal desert-adapted vertebrate. However, evidence from historical ecology, phylogenetics, anatomy, physiology, and biogeography qualifies this view significantly. Ancestors of G. agassizii stabilized as an essentially modern morph some 17-19 million yrs ago ago, perhaps 12 million yrs before the formation of ma...
متن کاملDesert Tortoise (Gopherus agassizii) Dietary Specialization Decreases across a Precipitation Gradient
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 the carbon and nitrogen isotope values in diet, and consequently represent a powerful tool to study animal feeding ecology. We measured the δ(...
متن کاملAccuracy and reliability of dogs in surveying for desert tortoise (Gopherus agassizii).
The desert tortoise (Gopherus agassizii) is federally listed as "threatened" and is afforded protection in several U.S. states including California, Nevada, Utah, and Arizona. Numerous factors ranging from habitat destruction to disease are thought to contribute to the species' decline throughout its range. Data collection on desert tortoises in the wild is challenging because tortoises are sec...
متن کاملLongevity and growth strategies of tiie desert tortoise {Gopherus agassizii) in two American deserts
The desert tortoise occurs in two strikingly different desert regimes in the southwestern United States. In the Mojave Desert, rainfall is more irregular and resources are more limited than in the Sonoran Desert. We examined the age structure of tortoise populations from these two deserts to determine whether the difference in resource availability has driven an evolutionary divergence in life ...
