The effect of mechanical canopy reduction on big sagebrush plant communities
Abstract A major conservation challenge in the western United States is implementing management treatments that reduce fire risk, control for invasive species, and maintain herbaceous understories in big sagebrush ecosystems. Studies have found that mechanical treatment of big sagebrush can reduce fire risk and promote herbaceous understories, but a ...

Abstract Forest fires in the southern Rocky Mountains are changing due to climate warming and increased fuel loads. Landscape‐scale stand‐replacement fires create extensive treeless swaths without regenerative seed sources, leading to long‐term conversion of coniferous forest to montane meadows and chaparral.

Divergent drought responses in two cold desert shrublands
Abstract The frequency and intensity of extreme droughts are projected to increase in the future, yet current research indicates that ecosystem sensitivity to extremes will vary. Despite hundreds of observational and experimental drought studies across ecosystems, the underlying mechanism explaining the inconsistent responses to drought remains poorly ...

Control of glyphosate-resistant Canada Fleabane in Ontario with multiple effective sites-of-action in glyphosate/dicamba-resistant soybean [PDF]
Canada fleabane is a winter or summer annual weed that is found throughout North America. Fall-emerged Canada fleabane can fix carbon early in the growing season, giving it a competitive advantage over nearby crop and weed species.

High sensitivity of herbaceous legumes to freezing: Insights from a multiyear snow removal study
Abstract Reductions in snow cover resulting from winter climate change are anticipated to increase the intensity of freezing exposure for overwintering herbaceous plants in many northern temperate regions. We examined whether herbaceous legumes, a key functional group responsible for increasing soil nitrogen inputs, are more sensitive to freezing than ...

In temperate, uniform rainfall environments, lucerne is the most reliably productive summer pasture option if soil conditions allow its growth. Chicory is a potential alternative to acidic soils. Good productivity combined with acid soil tolerance favours cocksfoot over tall fescue.

Hairy fleabane (Conyza bonarienis) response to saflufenacil in association with different formulations of glyphosate subjected to simulated rainfall [PDF]
Saflufenacil has been used to control glyphosate resistant weeds, including hairy fleabane. There are several glyphosate formulations, which are related to different salts and adjuvants.

Glyphosate-Resistant Hairy Fleabane (Conyza bonariensis) Is Reported in Greece
Overreliance on glyphosate can increase the risks of reduced efficacy of the herbicide on weeds and weed resistance, even in regions without glyphosate-resistant crops.

Phytochemical analysis of the extracts from the leaves of the plant fleabane (Conyza sumatrensis) revealed the presence of some substances such as tannins, flavonoids, saponins, steroids and glycosides. The presence of these substances is an indicator of

Factors affecting glyphosate control of horseweed (Conyza canadensis) and hairy fleabane (Conyza bonariensis) [PDF]
Experiments were conducted in 2006 and 2007 to determine if growth stage and rate would affect glyphosate control of horseweed and hairy fleabane. The Roundup Weathermax® formulation of glyphosate was applied at 0.5, 1.0, 1.5, and 2.0 lb ai/acre at four ...
