Information on the impact of climate change growth weed species and their sensitivity to herbicides could help establish an efficient management strategy. Due excessive use acetolactate synthase (ALS)-inhibitor herbicides, resistance those is increasing globally. It is, thus, crucial find out whether efficacy these will in future due increase temperatures carbon dioxide concentration. Therefore...

Arable land weed seed banks are dynamic and reflect cropping history, current management, and environment. Changes in crop rotation and tillage system can alter weed seed density and species composition. In the semi-arid region of the Pacific Northwest, USA, no-till spring cropping is being studied as an alternative to the traditional winter wheat (Triticum aestivum L.)/dust-mulch fallow (WWF) ...

Land, livestock, and wildlife managers need to understand the nutritional dynamics of forages to sustain adequate growth and reproduction of their animals and/or assure equitable payment for forages. Despite a long history of livestock grazing in the northern Great Basin, seasonal and annual nutritional dynamics of many of the region’s prominent grasses have not been described. We addressed thi...

Most ecologists believe that climate change poses a significant threat to the persistence of native species. However, in some areas climate change may reduce or eliminate nonnative invasive species, creating opportunities for restoration. If invasive species are no longer suited to novel climate conditions, the native communities that they replaced may not be viable either. If neither invasive ...

Forecasting how species will respond to climatic change requires knowledge of past community dynamics. Here we use time-series data from the small-mammal fossil records of two caves in the Great Basin of the American West to evaluate how contrasting and variable local paleoclimates have shaped small-mammal abundance dynamics over the last 7500 years of climatic change. We then predict how speci...
