Interactions between woody plants, elephants and other browsers in the Chobe riverfront, Botswana
(Norwegian University of Science and Technology, 2005-11)
This thesis examines the interaction between woody plants, elephants and other browsers in a semi-arid savanna in northern Botswana, southern Africa. Particularly I studied how woody plants respond to herbivory, how browsers ...
The Influence of topography and vegetation canopy on the deposition of atmospheric particulates Studied with 210Pb and 137Cs soil inventory measurements
(University of Edinburgh, 2003)
Naturally occurring radioactive isotopes of 210Pb and 7Be in the atmosphere, plant material and soil have been used to investigate the transport and removal of atmospheric aerosols from the atmosphere by precipitation and ...

between pre-service teachers' ...
Sprawl dynamics and the development of effective smart growth policies
(The Pennsylvania State University, 2006-11-15)
Sprawling urban development is a major driving force of global environmental change. Its impact on Earth system functions is likely to increase in the future when the proportion of the world’s population living in urban ...
Reservoir tillage for semi-arid environments
(Cranfield University, 2005-10)
The ever increasing world population, the decline in suitable agricultural land and food production levels require that new methods are found to increase land productivity or to bring into production land which is marginal. ...
