Spatial and ecological variation in dryland ecohydrological responses to climate change: implications for management

open access: yesEcosphere, 2016
Ecohydrological responses to climate change will exhibit spatial variability and understanding the spatial pattern of ecological impacts is critical from a land management perspective.

Evaluation of factors affecting greater prairie‐chicken nest and brood survival

open access: yesWildlife Biology, EarlyView.
Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...

Acclimation and hardening of a slow‐growing woody species emblematic to western North America from in vitro plantlets

open access: yesApplications in Plant Sciences, 2023
Premise Determining the tolerance of plant populations to climate change requires the development of biotechnological protocols producing genetically identical individuals used for genotype‐by‐environment experiments.

Apex predators exploit advantageous snow conditions across hunting modes

open access: yesJournal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

G80-510 Sagebrush Control [PDF]

open access: yes, 1980
Sagebrush is an all encompassing term commonly used to describe Artemisia species found on range and pasture lands in Nebraska. The dominant woody sagebrush species found in western Nebraska are sand sagebrush, fringed sagebrush, green sagewort, and big ...

Effects of Sagebrush Restoration and Conifer Encroachment on Small Mammal Diversity in Sagebrush Ecosystem [PDF]

open access: yes, 2019
Conifer encroachment in sagebrush ecosystems reduces habitat heterogeneity, niche space, and resource availability, all of which negatively affect many wildlife populations.

Threat Integration Model for Sagebrush (TIMS): A framework for using spatial decision support tools for strategic management of invasive annual grasses and conifers in sagebrush ecosystems

open access: yesConservation Science and Practice, EarlyView.
The Threat Integration Model for Sagebrush (TIMS) combines multiple spatial decision support tools to provide a unified, actionable map of sagebrush ecosystem conditions across the western United States. TIMS improves upon existing tools by including multiple threats in the same map (invasive annual grass [IAG] and conifer encroachment), characterizing

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees

open access: yesEcological Entomology, EarlyView.
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

Fine‐Scale Factors Affecting the Abundance and Thermal Sensitivity of Nonnative Brook Trout in Coldwater Rocky Mountain Streams

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The Brook Trout (Salvelinus fontinalis) is a globally distributed nonnative species that threatens native salmonids in coldwater streams. Understanding the factors regulating Brook Trout densities in coldwater refugia is critical to effective management, so we investigated (a) fine‐scale drivers of Brook Trout abundance and (b) factors ...

Interannual variation in climate contributes to contingency in post‐fire restoration outcomes in seeded sagebrush steppe

open access: yesConservation Science and Practice, 2022
Interannual variation, especially weather, is an often‐cited reason for restoration “failures”; yet its importance is difficult to experimentally isolate across broad spatiotemporal extents, due to correlations between weather and site characteristics ...
