Potentially toxic elements in wild Agassiz’s desert tortoises: tissue concentrations and association with disease [PDF]

Frontiers in Veterinary Science
BackgroundDesert tortoise (Gopherus agassizii) populations have continued to decline due to infectious and other diseases, predation, and habitat alteration. The potential contribution of minerals and heavy metals to tortoise health and susceptibility to

Scat as a source of DNA for population monitoring [PDF]

Ecology and Evolution, 2022
Sampling fecal droppings (scat) to genetically identify individual animals is an established method for monitoring mammal populations and could be highly useful for monitoring reptile populations. Whereas existing protocols for obtaining DNA from reptile

Upper respiratory tract disease and associated diagnostic tests of mycoplasmosis in Alabama populations of Gopher tortoises, Gopherus polyphemus. [PDF]

PLoS ONE, 2019
Upper respiratory tract disease (URTD) in North American tortoises (Gopherus) has been the focus of numerous laboratory and field investigations, yet the prevalence and importance of this disease remains unclear across many tortoise populations ...

Application of computer vision for off‐highway vehicle route detection: A case study in Mojave desert tortoise habitat

Remote Sensing in Ecology and Conservation
Driving off‐highway vehicles (OHVs), which contributes to habitat degradation and fragmentation, is a common recreational activity in the United States and other parts of the world, particularly in desert environments with fragile ecosystems.

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

Applying knowledge co‐production to identify Mojave desert tortoise stressors across time, space, and agency missions

Conservation Science and Practice
Considerable progress has been made in understanding the effects of stressors on Mojave desert tortoise (Gopherus agassizii) populations, yet information about how stressors may vary across jurisdictions, space, and time is lacking.

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 ...
