Water shortage is the primary limiting factor for crop production and long-term agricultural sustainability of the North China Plain. Forage cultivation emerged recently in this region. A fiver-year field experiment studies were conducted at Yucheng Integrated Experiment Station to quantify the water requirement and water use efficiency of seven forage varieties under climate variability, that ...

Gastrointestinal infections are still a major concern in the developing countries. The aim of this research was to investigate antimicrobial effects of five herbs in Iranian traditional medicine on some of the pathogenic intestinal bacteria. Hydroalcoholic extracts of Amaranthus paniculatus L. (seeds), Cannabis sativa L. (fruits), Rhus coriaria L. (epicarps), Urtica dioica L. (leaves), and Zata...

Unfortunately, this wealth of consumer choices comes at a steep cost. Non-native plants introduced through the horticulture trade often become invasive (Mack and Lonsdale ...

Climate models project that by 2100, the northeastern US and eastern Canada will warm by approximately 3– 5 8C, with increased winter precipitation. These changes will affect trees directly and also indirectly through effects on ‘‘nuisance’’ species, such as insect pests, pathogens, and invasive plants. We review how basic ecological principles can be used to predict nuisance species’ responses...
