Different methods were used intermittently to monitor the changes in the floristic composition, basal cover and density of the herbaceous and woody vegetation over a seven year period in the Kalahari Gemsbok National Park. Periods of drought and the variability of rainfall appear to have a significant influence in the short term on herbaceous species, while there was not much variation in the woody species composition or density.
A check list containing 397 plant species has been compiled for the Kalahari Gemsbok National Park which occupies an area of approximately 9 600 km2. These species represent 191 genera and 51 families. The Monocotyledonae are represented by 98 species (24,7 of the total number of species) and the Dicotyledonae by 299 species (75,3 of the total number of species). According to the life form spectrum the Kalahari Gemsbok National Park is a therophyte-hemicryptophyte area
Near-field test practices for the measurement of antenna properties are described in this document and near-field measurement practices for the three principal geometries: cylindrical, planar, and spherical are recommended. Measurement practices for the calibration of probes used as reference antennas in near-field measurements are also recommended
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
