South African grassland ecology and its restoration
… how human related disturbances affect mesic grasslands. I identified what was lost from the system after a disturbance and what biological constraints ecologists and managers will face when approaching their restoration. I then investigated biological limitations to grassland restoration by …

Resources, Environment, and Rural Development in Uruguay, 1779-1913
… well as on present-day scientific literature on grassland ecology. My approach is methodologically eclectic, and techniques vary as suits the diversity of the materials and the questions asked in each chapter. These include different quantitative methods (from descriptive statistics to regression …

Environmental Cues in the Seasonal Development of the Southern California Annual Grassland
<p>Annual grasslands characteristically experience a succession of seasonal phases which provide for the coexistence of various species by allowing them to make their major demands upon environmental resources at different times. Thus, an ecosystem furnishing certain resources at a limited rate is …

Linking plant traits and herbivory in grassland biodiversity-ecosystem functioning research
… experiments carried out in the understudied grasslands of Inner Mongolia, China. I found that a dominant generalist grasshopper Oedaleus asiaticus exhibits feeding preference for plants of high palatability when equally available, but in the field feeds on nearly any graminoid which is …

Plant Height Dynamics and Competition: From Local Interactions to Global Patterns
… interactions across environmental gradients in grassland ecosystems. First, I investigated how differences in maximum height influence species co-occurrence patterns along a competition intensity gradient measured using neighbour removal experiments. I found that negatively co-occurring species …

Long-term analysis and appropriate metrics of climate change in Mongolia
… the land atmospheric interactions over the grassland area depending on the different grazing intensity I conducted the case study over the Shortgrass Steppe Long-Term Ecological Research site on Northern Great Plains of US to imply the findings in semiarid shortgrass steppe of Mongolia. The …

An Assessment of the Use of Seeding, Mowing, and Burning in the Restoration of an Oldfield to Tallgrass Prairie in Lewisville, Texas
An examination of the effectiveness of seeding, burning, and mowing in the reestablishment of tallgrass prairie species on overgrazed and abandoned pastureland. The study site is a 20 acre tract on U.S. Corps of Engineers land below Lake Lewisville in Denton County, Texas. The site was partitioned …

Ecological assessments of Pseudomonas communities in pastoral soils: implications for disease suppression and sustainable production in agricultural grasslands
Grasslands are an important source of biodiversity, providing a range of essential ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are being used to support grazing livestock, with agricultural grasslands covering over 25% of the …

Spatial and temporal variation In greenhouse gas flux as affected by mowing on grasslands of hummocky terrain In Saskatchewan
… nutrient cycle that includes various GHGs. The grassland ecosystem plays a role in mitigating climate change by retaining carbon that would be released to the atmosphere with poor grazing management or the conversion to arable agriculture. Government agencies and the ranching industries could …
