"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...

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 ...
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...
Dynamic and innovative exhibit connects visitors to native habitats The PGAV Destinations-designed Chihuahuan Desert exhibit is now open at the El Paso Zoo, welcoming guests to celebrate and explore the flora and fauna of the surrounding desert environme
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...
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...
This pattern suggests that genetic structure of clonal plants is more dynamic than thought, and dispersal of different types of offspring affects genetic structure at many scales.Ecology and evolution [electronic resource]
There were also significant reductions in densities of annual plants growing under the shrubs than in the unplanted split-half of the plots. Successful establishment of creosotebush in desert grasslands is dependent upon the presence of large patches of soil with no perennial plant cover. Intense ...
