Tall fescue [Schedonorus arundinaceous (Schreb.) Dumort. nom. cons. Lolium arundinaceum Darbysh.] is the dominant pasture grass across much of southeast USA. The species productive, but grows slowly in summer. Plants also harbor an endophytic fungus (Epichloe coenophiala), which produces alkaloids that are toxic to cattle. Adding summer-productive forages fescue-based systems may benefit animal...

Mercury (Hg) is a global and widely distributed heavy metal pollutant. can affect human health as well the of ecosystems poses ecological risks. The subjects this study are three types grassland in Beidianzi region, Songnen Plains, Northeastern China, characterized by different degrees degradation. mercury content levels atmosphere, soil, forage grass on grasslands were determined. In addition,...

Grasslands are one of the largest carbon sinks and crucial in cycle. However, modelling each species' versus cover relationship is complex, ground flora covers plant functional types simplify model development provide a helpful link between physiologic strategies ecosystem processes. The present experiment randomly selected 115 quadrats 1×1 meters from Banaras Hindu University campus. herbaceou...

A feeding station is the area of forage a grazing animal can reach without moving its forefeet. Grazing behavior can be divided into residence within feeding stations (with bites as benefits) and movement between feeding stations (with steps as costs). However, relatively little information has been reported on how grazing animals modify their feeding station behavior seasonally and interannual...

A five-year experiment tested the response of aboveground net primary production (ANPP) and plant functional groups to manipulations in residual dry matter (RDM), reflecting typical grazing practices in Californian annual grasslands. The RDM treatments were 225, 560, 900 and 5000 kg ha with the latter treatment representing no grazing by livestock. ANPP in autumn, winter and spring showed a str...

a filed experiment was conducted to assay the effect of nitrogen fertilization and cultivated density on essential oil content on dragonhead (dracocephalum moldavica) in semi-arid conditions in 100 km of south east of mashhad. the experiment was done as factorial based on randomized complete blocks design with three replications, factor included four levels of nitrogen fertilization (0, 50, 100...
