Direct and Indirect Effects of Floral Defoliation on Photochemical and Non‐Photochemical Chlorophyll Fluorescence Dynamics of a Semiarid Bunchgrass

open access: yesPlant-Environment Interactions, Volume 7, Issue 1, February 2026.
After herbivory, crested wheatgrass florets must scrub excess absorbed light as heat via regulated physiological processes or less effective unregulated means. We found clipped florets heightened physiological control while undamaged florets reduced unregulated dissipation of excess light energy.

Simulated big sagebrush regeneration supports predicted changes at the trailing and leading edges of distribution shifts

open access: yesEcosphere, 2015
Many semi‐arid plant communities in western North America are dominated by big sagebrush. These ecosystems are being reduced in extent and quality due to economic development, invasive species, and climate change.

Projecting current and future location, quality, and connectivity of habitat for breeding birds in the Great Basin [PDF]

open access: yes, 2014
We estimated the current location, quality, and connectivity of habitat for 50 species of breeding birds in four mountain ranges in the central Great Basin (Lander, Nye, and Eureka Counties, Nevada) and projected the future location, quality, and ...

Supporting dryland restoration success with applied ecological forecasting of seeding outcomes

open access: yesRestoration Ecology, Volume 34, Issue 2, February 2026.
Abstract Introduction Ecological restoration is increasingly used to sustain biodiversity and ecosystem services. In drylands of the western United States (US), post‐disturbance restoration often involves seeding treatments to promote the recovery of native plant communities. Spatial and temporal variability in environmental conditions influences plant

Intercellular cavities in the rays of Dicotiledonous woods

open access: yesLilloa, 1938
An intercellular cavity within a radius differs from a radial gum canal because it is relatively short in length. Such cavities can be normal or traumatic.

A comparison and development of methods for estimating shrub volume using drone‐imagery‐derived point clouds

open access: yesEcosphere
Shrub volume is used to calculate numerous, essential ecological indicators in rangeland ecosystems such as biomass, fuel loading, wildlife habitat, site productivity, and ecosystem structure.

Phytochemistry Predicts Habitat Selection by an Avian Herbivore at Multiple Spatial Scales [PDF]

open access: yes, 2013
Animal habitat selection is a process that functions at multiple, hierarchically structured spatial scales. Thus multi-scale analyses should be the basis for inferences about factors driving the habitat selection process.

The Role of Leaf Wettability and Morphology on Leaf Surface Water Storage: A Cross‐Biome Synthesis

open access: yesEcohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The presence of water on leaves impacts plant function and ecosystem fluxes by supplementing moisture, reducing evapotranspirational demand and encouraging pathogen spread. Maximum phytoelement water storage capacity (MWSC)—the maximum amount of water that can be held on the surface of the leaf‐ is an important but poorly constrained parameter

Occupancy and abundance of predator and prey: implications of the fire‐cheatgrass cycle in sagebrush ecosystems

open access: yesEcosphere, 2016
Sagebrush (Artemisia tridentata) ecosystems are declining due to biological invasions and changes in fire regimes. Understanding how ecosystem changes influence functionally important animals such as ecosystem engineers is essential to conserve ...
