Differences in water balance between grassland and forest watersheds using long-term data, derived using the CoupModel
To quantify the role of land cover during a period of climate change, the runoff response is studied for Plynlimon in Wales, UK. The main objective was two-fold: (i) to create a protocol for modeling water balance on a daily basis; and (ii) to describe the extent to which the impact of land-use changes can be identified and supported by the long-term monitoring data of runoff from two ...

Playing hide and seek below the soil
Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

When planting trees does more harm than good
Note to anyone who thinks planting trees is the bees’ knees: Grasslands are important, too. With forests disappearing at record rates and the carbon sequestration and other benefits of vegetation getting increasing visibility, tree-planting has become almost an iconic “environmentally friendly” activity. But in some cases it could do more harm than good, according to Iowa State ...

Responses of a dominant temperate grassland plant (Leymus chinensis) to elevated carbon dioxide and nitrogen addition in China
Received for publication March 24, 2009. The impact of elevated atmospheric CO2 concentration on plant communities is varied and strongly dependent on the dominant species response, as well as nutrient conditions. Responses of a dominant species (Leymus chinensis) to elevated CO2 and N application were examined with open-top chambers in a typical temperate grassland in northern China for 3 yr. ...

Influence of microbial activity on plant–microbial competition for organic and inorganic nitrogen
Abstract To investigate how the level of microbial activity in grassland soils affects plant–microbial competition for different nitrogen (N) forms, we established microcosms consisting of a natural soil community and a seedling of one of two co-existing grass species, Anthoxanthum odoratum or Festuca rubra. We then stimulated the soil microbial community with glucose in half of the microcosms ...
