Mojave Desert Tortoise (Gopherus agassizii) Morphometrics and Egg Data from Seven Sites across the Mojave, (1997-2002)

These data were acquired from 7 study sites distributed across the range of Gopherus agassizii. Data were collected from 1997 to 2002 as part of three separate studies, although data were not collected at all sites in each year. Radio-transmitters were attached to the carapace of 151 females and VHF radio-telemetry was used to relocate animals to assess reproductive status. Egg production was determined from X-radiographs taken weekly/biweekly intervals (depending on the study) using a portable X-ray machine between April and July or August of each year. In addition, the mean carapace length (MCL) of each tortoise was measured at each time of capture or recapture using calipers (mm). A nesting event was recorded...

Activity and habitat selection by female desert tortoises in Mojave National Preserve, California USA 2011 - 2013

These data refer to habitat and activity data collected for female desert tortoises being monitored as part of a study on juvenile rearing and translocation for population augmentation purposes. The females were affixed with radio transmitters and radio tracked at least monthly to maintain knowledge of whereabouts. During those tracking events activity data were collected (surface or in burrows) and predominate habitat community recorded. Ancillary to this goal a habitat use study was conducted to determine the type of habitat occupied by females. Thus the data reference female morphology, activity, and a single instance of habitat use.
