Grass Seedling Demography and Sagebrush Steppe Restoration [PDF]

open access: yesRangeland Ecology & Management, 2012
Seeding is a key management tool for arid rangeland. In these systems, however, seeded species often fail to establish. A recent study in Wyoming big sagebrush steppe suggested that over 90% of seeded native grass individuals die before seedlings emerged.

Grazing intensity effects on herbaceous community composition in burned sagebrush steppe

open access: yesEcosphere, 2023
There is limited knowledge of grazing impacts on longer term plant community dynamics following fire in sagebrush steppe. This study evaluated vegetation response to different intensities of deferred rotation cattle grazing over 16 years (2007–2022) on ...

Influence of directional side of sagebrush canopies and interspaces on microhabitats

open access: yesBasic and Applied Ecology, 2023
Shrubs can contribute to spatial heterogeneity in plant communities by creating distinct microsites under their canopies compared to between their canopies (interspaces).

Intra‐site sources of restoration variability in severely invaded rangeland: Strong temporal effects of herbicide–weather interactions; weak spatial effects of plant community patch type and litter

open access: yesEcological Solutions and Evidence, 2022
Invasions by exotic annual grasses (EAGs) are replacing native perennials in semiarid areas globally, including the vast sagebrush‐steppe rangelands of western North America.

Seasonal temperature acclimatization in a semi-fossorial mammal and the role of burrows as thermal refuges. [PDF]

open access: yes, 2018
Small mammals in habitats with strong seasonal variation in the thermal environment often exhibit physiological and behavioral adaptations for coping with thermal extremes and reducing thermoregulatory costs.

The Seasonal Water Balance of Western-Juniper-Dominated and Big-Sagebrush-Dominated Watersheds

open access: yesHydrology, 2021
The combined impacts of woody plant encroachment and climate variability have the potential to alter the water balance in many sagebrush steppe ecosystems in the Western USA, leading to reduced water availability in these already water-scarce regions ...

Cumulative effects of an herbivorous ecosystem engineer in a heterogeneous landscape

open access: yesEcosphere, 2016
Foraging by herbivores alters individual plants and vegetation communities directly, and engineering behaviors such as bioturbation (digging and turning soil) and biodeposition (deposition of feces and urine) can affect soils and physical properties that

Do plant–soil feedbacks promote coexistence in a sagebrush steppe?

open access: yesEcology, 2023
AbstractRecent studies have shown the potential for negative plant–soil feedbacks (PSFs) to promote stable coexistence, but have not quantified the stabilizing effect relative to other coexistence mechanisms. We conducted a field experiment to test the role of PSFs in stabilizing coexistence among four dominant sagebrush steppe species that appear to ...

Harvester ant seed removal in an invaded sagebrush ecosystem: Implications for restoration

open access: yesEcology and Evolution, 2020
A better understanding of seed movement in plant community dynamics is needed, especially in light of disturbance‐driven changes and investments into restoring degraded plant communities.

Assemblages of herb-dwelling spiders (Araneae) of various steppe types in Ukraine and the Central Chernozem region of Russia [PDF]

open access: yes, 2012
A total of 107 spider species from 15 families were recorded in the herbaceous vegetation of the steppe ecosystems of Ukraine and the Central Chernozem region of Russia. Araneidae, Thomisidae, Salticidae and Theridiidae were the most species-rich.
