Pre‐fire grazing and herbicide treatments can affect post‐fire vegetation in a Great Basin rangeland
Ecological Solutions and Evidence, 2023 Management of wildfire associated with spread of the highly invasive annual grass Bromus tectorum (cheatgrass) is a critical need in the western U.S. We investigated the utility of coupling common rangeland management strategies pre‐fire to modify post ...

Fire promotes downy brome (Bromus tectorum L.) seed dispersal [PDF]
Biological Invasions, 2012 Particularly well-known among the many impacts of the invasive annual grass downy brome (Bromus tectorum, Poaceae) is its ability to alter fire cycles and increase in abundance after fire. However, little is known about how fire influences B. tectorum dispersal. We quantified fire effects on B.

LONG-TERM EFFECTS OF TEBUTHIURON ON BROMUS TECTORUM
Western North American Naturalist, 2006 Abstract Use of herbicides to thin dense stands of Artemisia spp. (sagebrush) can free up resources for herbaceous plants and increase forage production, but may also facilitate weed invasion. We revisited a sagebrush thinning experiment in a north central Wyoming big sagebrush–grassland 11 years after application of tebuthiuron (N-[5-(1,1 ...

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA
Wildlife Biology, EarlyView.Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Revisiting the Life Cycle of Dung Fungi, Including Sordaria fimicola. [PDF]
PLoS ONE, 2016 Dung fungi, such as Sordaria fimicola, generally reproduce sexually with ascospores discharged from mammalian dung after passage through herbivores. Their life cycle is thought to be obligate to dung, and thus their ascospores in Quaternary sediments ...

Data reconciliation in multi‐trait experiments with kinship ordination
Methods in Ecology and Evolution, EarlyView.Abstract A central aim in biology is understanding the heritability of traits and how trait interactions contribute to success in diverse environments. Experiments that record multiple traits from individuals of known pedigree or genetic relatedness in distinct environments are key to addressing this aim.
