Additionally, the small values of B and Ba of the Levin's index and the standardized Levin's index for niche breadth indicate a specialized alimentary behavior, which further supports that the bobcat is a specialist forager in the Chihuahuan Desert
This area lies within the northern region of the Chihuahuan Desert
. Twenty-two egg masses deposited by R.
We live in the Chihuahuan desert
, an area that only gets an average 11 inches of rain per year (for the past few years the average has been closer to 7 inches!), so rather than depend on an already overtaxed aquifer for our household water needs, we decided to install a rainwater harvesting system.
Chopping hopes to improve the accuracy of these maps by using multiangle sensing techniques and has tested these using data from two sites in the Chihuahuan Desert
as well as over similar semiarid rangelands in Inner Mongolia.
Ants removed more seeds than did rodents in the grassland sites but rodents removed more seeds than did ants in the creosotebush sites and seed removal rates by rodents and ants were the same in the mesquite sites, Our data support the hypothesis that livestock grazing leads to a shift from grassland to shrubland in the Chihuahuan Desert
, with associated changes in the structure and functioning of faunal communities.
Although I photograph National Park System areas all over the country, I always return to the Chihuahuan Desert
parks of west Texas and southeastern New Mexico.
We sampled grassland and shrubland sites at the Sevilleta National Wildlife Refuge (n = 1 each) and the Jornada Experimental Range (n = 2 each) in the Chihuahuan Desert
of New Mexico, where various desert shrubs, including Larrea tridentata, have invaded perennial grasslands, dominated by Bouteloua eriopoda, during the last century (Buffington and Herbel 1965).
Vegetation in the area is Chihuahuan Desert
scrub interspaced with desert grasses of various species and flora of the Rio Grande Valley (Johnson, 2000).
The Trans-Pecos is located within the Chihuahuan Desert
. The study areas range in elevation from 475 m (above sea level) along the Rio Grande at BGWMA to 2,667 m at Guadalupe Peak in the Guadalupe Mountains (Powell 2000).
It is originally from Mojave Desert, Chihuahuan Desert
and Sonoran Desert of southeastern California, Baja California, New Mexico, southern Nevada and Arizona.
Around 80 million years ago, this particular dinosaur would have been shovelling through loose, wet sediment to scoop loosely-rooted aquatic plants from the tidal marshes of an ancient delta, where today lies the Chihuahuan desert
. When the dinosaur died, some of its bones were transported downstream by the tide and became lodged in vegetation.
Chronic wasting disease (CWD) is becoming increasingly widespread in the arid Southwest, including the Chihuahuan Desert
