Climate change predictions include warming and drying trends, which are expected to be particularly pronounced in the southwestern United States. In this region, grassland dynamics are tightly linked to available moisture, yet it has proven difficult to resolve what aspects of climate drive vegetation change.Here, we combine climate and soil properties with a mechanistic soil water model to explain temporal fluctuations in perennial grass cover, quantify where and the degree to which incorporating soil water dynamics enhances our ability to understand temporal patterns, and explore the potential consequences of climate change by assessing future trajectories of important climate and soil water variables.Our analyses...
These heatmaps show a top 3 grassland habitat fragmentation and loss stressor, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor across the landscape. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for each of the top 3 stressors that participants chose. Counties with a small number of participants were not adjusted for small sample size. These results were shared via a webinar hosted by...

University of California Riverside’s Center for Conservation Biology will create a sustainable resource monitoring framework that will provide empirical data identifying if and how climate change is changing the composition and vitality of Joshua Tree National Park. These data will then help focus the Park’s resource management programs to help ensure the Park’s rich biodiversity can be sustained to the extent possible. A broader goal is to have this framework adopted across the surrounding public lands to then integrate data from multiple sites and land management philosophies to create an unambiguous picture of the impacts of climate change across the desert region.

ABSTRACT: The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside from detrimental effects...

Description: Invasive saltcedar is the third most abundant tree in Southwestern riparian systems. Resource managers must often balance the goals of protecting native wildlife species and habitats with the control of non-native and invasive plants. This project examined the impact of the tamarisk leaf beetle (a biocontrol agent) on amphibian and reptile (herpetofauna) and bird populations and communities along the Virgin River in Utah, Arizona and Nevada.Building on two years of pre-biocontrol monitoring, the researchers tracked changes in herpetofauna communities as the biocontrol entered a system dominated by a non-native plant species. The tamarisk leaf beetle is known to be eaten by several wildlife species....

Despite the lack of surface flows, the Colorado River riparian corridor in Mexico has proven to be ecologically resilient. Floods in the 1980s and 90s in the region brought back large swaths of native riparian habitat, which still persist today in some areas along the river. Because the historic floodplain is extremely important for agricultural production and therefore the local economy, habitat maintenance must be integrated with continued utilization of lands and water for this purpose.The riparian, marsh, and open-water areas found in Reach 4 provide critical habitat for both migratory and resident riparian bird species. Due to its ecological importance, the riparian corridor and Reach 4 in particular have been...

Desert LCC Base Maps and Data describe the physical and cultural geography of the Desert Landscape Conservation Cooperative. These products include the Desert LCC vector boundary available as a shapefile and KML, as well as print-quality graphic design files for thematic maps including Watersheds, Land Cover, Vegetation and a Base Map. The scale of the maps is 1:2,500,000. About the Desert LCC Region: Forty percent of the Desert LCC area lies in the United States and the remaining 60 percent, in Mexico. The total DLCC area is 536,955 square miles or 1,390,713 square kilometers. To explore data per Desert LCC priorities, visit the Conservation Planning Atlas.

Rocky Mountain Research Station scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. By re-measuring vegetation and bird populations following wildfires and applying climate change models, they will assess the singular and synergistic effects of climate change and wildfire and provide strategies for managing resilient forests and conserving the avian community structure. They will also continue and expand citizen science efforts to develop a long term avian monitoring plan, as well as simulation studies to provide optimal monitoring designs for avian species to detect changes from large-scale stressors.

Final Report WaterSMART Agreement No. R13AP80033Introduction: Sky Island Alliance is a non‐governmental organization that works to protect and restore the rich natural heritage of native species and habitats in the Sky Island Region. We work with volunteers, scientists, land‐owners, public officials, and government agencies to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity.Springs are keystone ecosystems in the Sky Island Region, exert disproportionate influence on surrounding landscapes, and are known to be biodiversity hotspots. Although they are abundant in this arid region, they are poorly documented and little studied. Changing...

Executive Summary: Our project combined field surveys of fish communities and habitat characteristics with estimates of population genetic structure to identify and evaluate critical factors influencing fish communities in the Gila River basin of New Mexico. Fish communities were structured along a strong habitat gradient associated with stream size, with distinct differences in the distribution of native and nonnative fishes. Nonnative warm-water species generally occurred in mainstem habitats, whereas coldwater nonnative salmonids occurred in high elevation tributaries. Habitat affinities of native species varied, with some occurring in mainstem habitats and others in tributaries. Several native species, such...

Prymnesium parvum (golden alga, GA) is a toxigenic harmful alga native to marine ecosystems that has also affected brackish inland waters. The first toxic bloom of GA in the western hemisphere occurred in the Pecos River, one of the saltiest rivers in North America. Environmental factors (water quality) associated with GA occurrence in this basin, however, have not been examined. Water quality and GA presence and abundance were determined at eight sites in the Pecos River basin with or without prior history of toxic blooms. Sampling was conducted monthly from January 2012 to July 2013. Specific conductance (salinity) varied spatiotemporally between 4408 and 73,786 mS/cm. Results of graphical, principal component...
