Where the desert meets the river: Investigating southwestern riparian ecosystems

Science Spotlights Posted on: August 23, 2019
Rivers and streams of the American Southwest have been heavily altered by human activity, resulting in significant changes to disturbance regimes. Riparian vegetation in aridland floodplain systems is critically important as foraging, migrating, and breeding habitat to birds and other animal species. To conserve riparian ecosystems and organisms, understanding how plants and animals are affected by disturbance processes and multiple stressors is critical.

Use of native and nonnative nest plants by riparian-nesting birds along two streams in New Mexico

Publications Posted on: July 25, 2019
Nonnative plant invasions are a management concern, particularly in riparian forests, but little is known about mechanisms through which they influence vertebrate communities. In the American Southwest, native trees such as cottonwood (Populus spp.) are thought to provide better habitat for breeding birds than nonnative plants, which are more tolerant of human-altered conditions.

Climate change and wildfire effects in aridland riparian ecosystems: An examination of current and future conditions

Publications Posted on: June 21, 2017
Aridland riparian ecosystems are limited, the climate is changing, and further hydrological change is likely in the American Southwest. To protect riparian ecosystems and organisms, we need to understand how they are affected by disturbance processes and stressors such as fire, drought, and non-native plant invasions.

Nest-location and nest-survival of black-chinned hummingbirds in New Mexico: A comparison between rivers with differing levels of regulation and invasion of nonnative plants

Publications Posted on: March 04, 2015
We compared plants used as sites for nests and survival of nests of black-chinned hummingbirds (Archilochus alexandri) along two rivers in New Mexico. Along the free-flowing Gila River which was dominated by native plants, most nests were constructed in boxelder (Acer negundo).

Data report for completed spur-dike configurations within the native topography model

The Middle Rio Grande is a 29-mi reach of the Rio Grande in central New Mexico extending from the downstream side of Cochiti Dam to Bernalillo, New Mexico. A map of the Middle Rio Grande reach is presented in Figure 1.1.

Abundance of wind scorpions (Solifugae: Eremobatidae) in riparian forests disturbed by grazing, fire, and flood in Central New Mexico, USA

Publications Posted on: April 26, 2011
Historically, flood was the primary disturbance structuring riparian plant and animal communities in the southwestern United States. In many areas, however, livestock grazing and wildfire occur more frequently than flooding. Research has shown that changes in flood and fire frequency affect the composition of riparian surface-active arthropod communities (Bess et al. 2002, Ellis et al. 2001).

Landbird migration along the Middle Rio Grande: Summary of banding data from spring and fall 1994

Publications Posted on: April 13, 2011
Northbound and southbound movement along major waterways is characteristic of migratory birds nesting in North America. It is likely that river corridors are more important to migrating birds in arid parts of North America than in humid, more heavily vegetated areas (Wauer 1977).

Case Study 3: Species vulnerability assessment for the Middle Rio Grande, New Mexico

Publications Posted on: March 02, 2011
This case study describes a method for scoring terrestrial species that have potential to be vulnerable to climate change. The assessment tool seeks to synthesize complex information related to projected climate changes into a predictive tool for species conservation. The tool was designed to aid managers in prioritizing species management actions in response to climate change projections.

Snake, rattle, and roll: Investigating the snakes that live in the Bosque along the Middle Rio Grande

Publications Posted on: September 14, 2010
After an area has been changed by human or natural disturbances, forest managers often engage in restoration activities. In the Bosque, fire is both a human and a natural disturbance. This is because most fires in the Bosque are started by humans. Restoration activities are things that forest managers do to the land to help an area resemble how it functioned in the past.

Landbird migration in riparian habitats of the Middle Rio Grande: A case study

Publications Posted on: July 19, 2010
Growing human populations and rapid ecological changes threaten the sustainability of the middle Rio Grande, a river corridor important to numerous species of wintering, breeding, and migrating waterfowl, shorebirds, and songbirds.
