1. How does grazing and burning affect the occurrence and development of vascular plants?
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Grazing and burning are disturbances that can be used for management of landscapes that are in need of restoration. When applying these disturbances, you can create a more diverse flora and fauna and control the grazing pressure from domestic cattle. LÄS MER
2. Spatial and temporal variability in grassland structure associated with different densities of the white rhinoceros (Ceratotherium simum) in a South African savanna
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : The direct and indirect relationships between species in different trophic levels are referred to as trophic dynamics and are important in maintaining the function of ecosystems. Megaherbivores may have effects both directly and indirectly on other species since their impact may be disproportionately large relative to their population size. LÄS MER
3. Grazing impacts on savanna vegetation states and its role in albedo changes
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Albedo, i.e., the fraction of the incoming sunlight that a surface reflects, has been previously shown to play a key role on the climate system by influencing the energy balance of the Earth’s ecosystems. LÄS MER
4. Grazing increases albedo of savanna grasslands
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Earlier studies done in the north have shown that grazing increases surface albedo by reducing shrub height and abundance, and thus have the potential to cool down the local climate. But what about effect of grazing in other systems? In African savanna grasslands some grazers are able to transform grass swards into a lawn-like state by regular grazing. LÄS MER
5. Assessing vegetation changes for parts of the Sudan and Chad during 2000-2010 using time series analysis of MODIS-NDVI
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Phenological vegetation characteristics are valuable inputs to several ecosystem-related models: including carbon exchange and climate change. Phenological characteristics are effective measures of changes in vegetation in an area and are subject to the seasonal and inter-annual climatic variations. LÄS MER
