Nutrient subsidies to belowground microbes impact aboveground food web interactions.
Historically, terrestrial food web theory has been compartmentalized into interactions among aboveground or belowground communities. In this study we took a more synthetic approach to understanding food web interactions by simultaneously examining four trophic levels and investigating how nutrient (nitrogen and carbon) and detrital subsidies impact the ability of the belowground microbial commu...
متن کاملSoil Organic Carbon Stocks and Nitrogen Content Comparison in Different Slope Positions in Native Grasslands and Adjacent Cultivated Soils (Case Study: Kermanshah Mountain Rangelands, Iran)
Global warming has been largely driven by increasing atmospheric GHG (Green House Gasses), particularly carbon dioxide caused by fossil fuels burning. The current trend can not be stopped except by reducing fossil fuel consumption or storing organic carbon in soil or earthchr('39')s biological systems such as forests, rangelands and agricultural systems. This study was conducted to determine th...
متن کاملMore is not necessarily better: the impact of limiting and excessive nutrients on herbivore population growth rates
1. The body tissues of insect herbivores contain higher concentrations of nitrogen and phosphorus than do their host plants, leading to an elemental mismatch that can limit herbivore growth, fecundity and ultimately influence population dynamics. While low nutrient availability can limit herbivore growth and reproduction, nutrient levels that exceed an organism’s nutritional requirements, i.e. ...
متن کاملThe impact of atmospheric temperature and soil nitrogen on some physiological traits and dry matter accumulation of wheat (Triticum aestivum cv. Bahar)
Wheat is the most important cereal crop in the world as well as in Iran. The studies related to the effects of global climate change on wheat production usually assess the impact of changes in atmospheric CO2 concentration and temperature on growth and yield. On the other hand, nitrogen is the most crucial plant nutrient for crop production and the proper management and improving the utilizatio...
