Trajectories and drivers of compositional and functional variation in sagebrush steppe restoration

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Restoration success is often challenged by unpredictable and undesirable outcomes, especially in arid systems like the sagebrush steppe. In an 11‐year study in Grand Teton National Park, climatic conditions during establishment and local soil texture drove long‐term differences in plant community composition and functional traits.

The Heritability of Migration Behaviors in a Wide‐Ranging Ungulate

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Despite our understanding that variation in migration behavior has both genetic and environmental components, studies quantifying the sources of genetic variation contributing to migration phenotypes are lacking. Our study provides, to our knowledge, the first empirical evidence of heritability in migration behavior in ungulates.

Spatial patterning of Wyoming big sagebrush indicates negative density dependence

Ecosphere, 2022
Plants reflect resource use in their spatial patterning. Competition for limited resources—such as available soil water in a dryland ecosystem—drives establishment, growth, and mortality, resulting in shifts of spatial arrangement over time.

Nutritional and reproductive dynamics of moose near their southern range limit

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Soil characteristics are associated with gradients of big sagebrush canopy structure after disturbance

Ecosphere, 2019
Reestablishing shrub canopy cover after disturbance in semi‐arid ecosystems, such as sagebrush steppe, is essential to provide wildlife habitat and restore ecosystem functioning.

Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
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 ...

Comparing Accuracy and Biases of DNA Metabarcoding, Hybridization Capture, and Metagenomic Sequencing for Quantifying Herbivore Diets

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT DNA metabarcoding using relative read abundance (RRA) is commonly applied to estimate herbivore diet composition, yet its quantitative accuracy remains uncertain. We assessed taxonomic resolution and quantitative performance of RRA from DNA metabarcoding compared to metagenomic sequencing and hybridization capture, using deer scats from ...

Collet Hairs Are Critical for Anchoring and Survival of Arabidopsis thaliana Seedlings During Early Development

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Rapid and successful establishment of seedlings, beginning with the penetration of the emerging radicle into the soil, is essential for survival. In roots, root hairs increase the surface area for the absorption of water and solutes while providing the mechanical anchorage necessary for deeper soil penetration during elongation.
