"Plants of the Chihuahuan Desert: This guide uses color photographs and brief descriptions to help identify a variety of plants native to the northern Chihuahuan Desert, including Big Bend National Park, Big Bend Ranch State Park, and the Davis Mountains. Split into helpful categories of trees, ...
These predicted climate changes have triggered strong concerns in conservation biologists because the Chihuahuan Desert harbors an elevated richness of succulent plants (Rzedowski, 1991). Nevertheless, there is little information about how these plants will respond when facing increased temperatures, especial...

“With the opening of the Chihuahuan Desert, we aim to motivate guests and their families to go and explore these stunning and varied environments in our surrounding State and National Parks,” said El Paso Zoo director Joe Montisano. “From the wonders of wildlife in their own backyards to ...
to to the health of desert soils. Their two greatest contributions are “fixing” nitrogen and carbon from the atmosphere and converting them into forms that plants can use. This is important because lack of nitrogen is often as great a barrier to desert plant life as is the lack of water...
Chihuahuan desertscrub on limestone substrates is dominated by creosotebush (Larrrea divaricata), Chihuahuan whitethorn (Acacia neovernicosa), mariola (Parthenium incanum), and tarbush (Flourensia cernua). Riparian vegetation along a rocky bedrock/ gravel wash includes desert willow (Chilopsis ...
The obligate riparian shrub, Chilopsis linearis (desert willow), had intermediate gas-exchange rates when compared with Apache plume and mesquite, and neither soil water nor nutrient concentrations appeared to affect photosynthesis during the growing season. Variation between and within arroyos was high...
Chihuahuan DesertGrasslandsShrublandsSpecies richnessPrecipitation variability and shrub encroachment in response to global environmental change are likely to affect both richness and aboveground net primary production (ANPP) of annual plants in arid and semi-arid ecosystems in the northern Chihuahuan Desert,...
The current current ongoing expansion of shrubs at the expense of grasses in the Chihuahuan Desert is largely believed to result from a shift in competition between shrubs and grasses. Both groups, shrubs and grasses, occupy a gently sloping silty (loessial) soil within the Jornada Experimental...
To test this hypothesis we used populations of the desert cactus Opuntia rastrera which has different recruitment rates in the two adjacent habitats where it grows. In Opuntia-dominated scrublands (nopaleras, density ca. 4,000 plants/ha) 1 seedling out of 7,000,000 seeds establish, whereas ...
