Weak interspecific interactions in a sagebrush steppe? Conflicting evidence from observations and experiments.
Sign Up to like & getrecommendations! Published in 2018 at "Ecology"
DOI: 10.1002/ecy.2363
Abstract: Stable coexistence requires intraspecific limitations to be stronger than interspecific limitations. The greater the difference between intra- and interspecific limitations, the more stable the coexistence, and the weaker the competitive release any species should experience… read more here.

Simulating cheatgrass (Bromus tectorum) invasion decreases access to food resources for small mammals in sagebrush steppe

DOI: 10.1007/s10530-018-1701-8
Abstract: Invasions by nonnative plants can alter the abundance of native animals, yet we know little about the mechanisms driving these changes. Shifts in vegetation characteristics resulting from nonnative plants can alter availability of food resources,… read more here.

DOI: 10.1016/j.catena.2019.104301
Abstract: Abstract Woody species encroachment into herbaceous and shrub-dominated vegetations is a concern in many rangeland ecosystems of the world. Arrival of woody species into affected rangelands leads to changes in the spatial structure of vegetation… read more here.

DOI: 10.1016/j.foreco.2017.06.033
Abstract: Abstract Pinon-juniper woodlands of the western United States have expanded 2 to 10-fold since the late 1800’s. Tree control measures using chainsaws, heavy equipment and prescribed fire have been used to reduce woodlands and restore… read more here.

Spatiotemporal dynamics of insect pollinator communities in sagebrush steppe associated with weather and vegetation

DOI: 10.1016/j.gecco.2021.e01691
Abstract: Abstract The conservation of native insect pollinators is hampered by a lack of information about environmental factors influencing pollinator communities. We investigated how insect pollinator communities, composed of bees (Hymenoptera), butterflies and moths (Lepidoptera), and… read more here.

DOI: 10.1016/j.rama.2017.02.001
Abstract: ABSTRACT Feral horses inhabit rangeland ecosystems around the world, and their impacts on riparian ecosystems are poorly understood. We characterized impacts of a free-ranging horse population on the structure and composition of riparian plant communities… read more here.

DOI: 10.1071/wf19109
Abstract: We assessed plant community succession following prescribed fire on ungrazed Wyoming big sagebrush steppe, eastern Oregon. Treatments were burned (Burn; September and October, 2002) and unburned (Control) sagebrush steppe. Herbaceous yield, vegetation canopy cover and… read more here.

DOI: 10.1093/aobpla/plab047
Abstract: Restoration of dryland ecosystems is often limited by low seedling establishment and survival. Defoliation caused by insects and small mammals could be an overlooked cause of seedling mortality. In the sagebrush steppe, we examined the… read more here.

Soil microbial communities and elk foraging intensity: implications for soil biogeochemical cycling in the sagebrush steppe.

DOI: 10.1111/ele.12722
Abstract: Foraging intensity of large herbivores may exert an indirect top-down ecological force on soil microbial communities via changes in plant litter inputs. We investigated the responses of the soil microbial community to elk (Cervus elaphus)… read more here.
