Flooding and its influence on diazotroph populations and soil nitrogen levels in the Okavango Delta
(South African Journal of Botany http://www.elsevier.com/wps/find/journaldescription.cws_home/707238/description#description, 2004)
Effects of flooding on soil nitrogen (N), and asymbiotic
nitrogen fixing bacterial (diazotroph) populations of the
Okavango Delta were investigated. Diazotrophs from
the rhizosphere of dominant annual and perennial
grasses ...
Seasonal variation in energy influxes and carbon dioxide exchange for a broad-leaved semi-arid savanna (Mopane woodland) in Southern Africa
(Blackwell publishing, www.blackwellpublishing.com, 2004)
We studied the seasonal variation in carbon dioxide, water vapour and energy fluxes in a broad-leafed semi-arid savanna in Southern Africa using the eddy covariance technique. The open woodland studied consisted of an ...
