Links Between Grasslands and Carbon Storage
Carbon dioxide is one of many greenhouse gases that help warm the atmosphere by trapping heat radiating from earth. This trapped heat is called the greenhouse effect and without it the earth would be about 33 degrees C colder (Janzen et al. 2002). It is however possible to have too much of a good thing. Most troublesome has been the increase in concentration of carbon dioxide over the last cent...
متن کاملSoil Carbon Storage in Mountain Grasslands of Kashmir, India
On account of their ecological, economical and cultural significance, grasslands are an important mark and a unique heritage in Jammu and Kashmir. However, the details of distribution of vast reserves of soil organic carbon (SOC) in these ecosystems are not well known because most of the previous investigations on these ecosystems have been devoted towards highlighting their importance as repos...
متن کاملStorage, patterns and controls of soil organic carbon in the Tibetan grasslands
The soils of the Qinghai-Tibetan Plateau store a large amount of organic carbon, but the magnitude, spatial patterns and environmental controls of the storage are little investigated. In this study, using data of soil organic carbon (SOC) in 405 profiles collected from 135 sites across the plateau and a satellite-based dataset of enhanced vegetation index (EVI) during 2001–2004, we estimated st...
متن کاملShrub encroachment can reverse desertification in semi-arid Mediterranean grasslands.
The worldwide phenomenon of shrub encroachment in grass-dominated dryland ecosystems is commonly associated with desertification. Studies of the purported desertification effects associated with shrub encroachment are often restricted to relatively few study areas, and document a narrow range of possible impacts upon biota and ecosystem processes. We conducted a study in degraded Mediterranean ...
