Cheatgrass Invasion - The Below-Ground Connection
Journal of Environment and Ecology, 2017 Plant-soil microbial feedback loops play an important role in the establishment and development of plant communities. Microbial soil communities, including pathogens, plant-growth-promoting rhizobacteria and their reciprocal interactions, can influence plant health and nutrient cycling in many ways. We are proposing a model that accounts for cheatgrass

Complementary network-based approaches for exploring genetic structure and functional connectivity in two vulnerable, endemic ground squirrels [PDF]
, 2017 The persistence of small populations is influenced by genetic structure and functional connectivity. We used two network-based approaches to understand the persistence of the northern Idaho ground squirrel (Urocitellus brunneus) and the southern Idaho ...

Long‐term effects of tree expansion and reduction on soil climate in a semiarid ecosystem
Ecosphere, 2020 In sagebrush ecosystems, pinyon and juniper tree expansion reduces water available to perennial shrubs and herbs. We measured soil water matric potential and temperatures at 13–30 and 50–65 cm soil depths in untreated and treated plots across a range of ...

Patterns in Cheatgrass Abundance in Foothills Grasslands in Montana
Journal of Environment and Ecology, 2022 Cheatgrass (Bromus tectorum L.) is an invasive, exotic annual grass that exerts substantial negative ecological and economic influence in many of the ecosystems it invades. Cheatgrass has been extensively studied in the Great Basin region of North America where most precipitation comes in winter and early spring and the vegetation consists primarily of

Grazing intensity effects on herbaceous community composition in burned sagebrush steppe
Ecosphere, 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 ...

Fire Effects on the Cheatgrass Seed Bank Pathogen Pyrenophora semeniperda [PDF]
Rangeland Ecology & Management, 2011 The generalist fungal pathogen Pyrenophora semeniperda occurs primarily in cheatgrass (Bromus tectorum) seed banks, where it causes high mortality. We investigated the relationship between this pathogen and its cheatgrass host in the context of fire, asking whether burning would facilitate host escape from the pathogen or increase host vulnerability ...
