Statistical analysis of hydrologic data for Yucca Mountain; Yucca Mountain Site Characterization Project [PDF]
The geologic formations in the unsaturated zone at Yucca Mountain are currently being studied as the host rock for a potential radioactive waste repository. Data from several drill holes have been collected to provide the preliminary information needed for planning site characterization for the Yucca Mountain Project.

Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths
Abstract Soil waters are a central component of the terrestrial water cycle. Their δ2H, δ18O, and d‐excess values contain rich information about hydroclimate, including the source of moisture and its evaporative history. Paleoclimate workers seek to investigate ancient hydroclimates via triple oxygen isotope geochemistry, termed Δ′17O, which is ...

Evaporation and Near‐Surface Heat Transport in Groundwater Discharge Areas
Abstract I present a model of coupled advective/conductive heat transport that incorporates key processes acting in the near‐surface environment of a groundwater discharge zone, including convective heat transfer between the land surface and the atmosphere and evaporative cooling.

Yucca Mountain and The Environment [PDF]
The Yucca Mountain Project places a high priority on protecting the environment. To ensure compliance with all state and federal environmental laws and regulations, the Project established an Environmental Management System. Important elements of the Environmental Management System include the following: (1) monitoring air, water, and other natural ...

Factors affecting early plant survival in restoration of Mediterranean‐type climate shrublands
We undertook post‐fire restoration in southern California's shrubland with some portion of plants receiving supplemental irrigation. After 2.5 years survival was higher in California sage scrub (CSS) versus chaparral species and only slightly higher in irrigated individuals.

Novel Glomeromycotina–moss associations identified in California dryland biocrusts
Summary Drylands, which comprise c. 45% of Earth's land area, host biological soil crusts (biocrusts): symbiotic communities of cyanobacteria, fungi, algae, lichen, and bryophytes that stabilize soil and support key ecosystem functions. Moss‐dominated biocrusts are particularly interesting due to their potential to illuminate ancient bryophyte–fungal ...

Wilting wildflowers and bummed‐out bees: Climate change threatens US state symbols
Abstract Species designated as state symbols in the United States carry cultural importance, embody historical heritage and maintain long‐standing linkages to Indigenous traditions. However, they are threatened by climate change and even face the risk of local or global extinction.

Dog attacks on wild desert tortoises: A risk model
Domestic dogs attack and severely injure wild desert tortoises at the urban and ex‐urban interface with deserts. Severe trauma to tortoises increased 4 times to shell and limbs and 16.5 times to the gular horn over the decades between the 1970s and 2000s. Tortoises were at exponential risk of severe trauma when living within 12 km of settlements, towns,

Winter-hardy palm lilies and opportunities of their employment in Hungary
The Yucca species are the plants of tropical, subtropical, arid mountain and desertic regions. The genus does only grow naturally in the new world spreading neotropic, the centre of their diversity is Central America.
