| general microbiota of the soft tick ornithodoros turicata parasitizing the bolson tortoise (gopherus flavomarginatus) in the mapimi biosphere reserve, mexico. | the general bacterial microbiota of the soft tick ornithodoros turicata found on bolson tortoises (gopherus flavomarginatus) were analyzed using next generation sequencing. the main aims of the study were to establish the relative abundance of bacterial taxa in the tick, and to document the presence of potentially pathogenic species for this tortoise, other animals, and humans. the study was carried-out in the mapimi biosphere reserve in the northern-arid part of mexico. bolson tortoises (n = 45 ... | 2020 | 32899580 |
| sleep patterns in a chelonian reptile (gopherus flavomarginatus). | individuals of gopherus flavomarginatus, previously adapted to experimental conditions were chronically implanted for polygraphic recordings. four different states of vigilance were observed:. active wakefulness, quiet wakefulness, quiet sleep and active sleep. eeg was polymorphic and irregular showing a decreasing tendency in frequency and amplitude when passing from wakefulness to quiet sleep. heart rate decreased with sleep but it was slightly higher during active sleep than quiet sleep. moto ... | 1988 | 3222357 |
| genetic assessments and parentage analysis of captive bolson tortoises (gopherus flavomarginatus) inform their "rewilding" in new mexico. | the bolson tortoise (gopherus flavomarginatus) is the first species of extirpated megafauna to be repatriated into the united states. in september 2006, 30 individuals were translocated from arizona to new mexico with the long-term objective of restoring wild populations via captive propagation. we evaluated mtdna sequences and allelic diversity among 11 microsatellite loci from the captive population and archived samples collected from wild individuals in durango, mexico (n = 28). both populati ... | 2014 | 25029369 |
| using range-wide abundance modeling to identify key conservation areas for the micro-endemic bolson tortoise (gopherus flavomarginatus). | a widespread biogeographic pattern in nature is that population abundance is not uniform across the geographic range of species: most occurrence sites have relatively low numbers, whereas a few places contain orders of magnitude more individuals. the bolson tortoise gopherus flavomarginatus is endemic to a small region of the chihuahuan desert in mexico, where habitat deterioration threatens this species with extinction. in this study we combined field burrows counts and the approach for modelin ... | 2015 | 26115482 |
