Remote sensing-derived hydroperiod as a predictor of floodplain vegetation composition
(Springer Link; https://link.springer.com, 2014-02-13)Characterising hydroperiod and vegetation for flood-pulsed wetlands is a critical first step towards understanding their ecology. In large, data-poor wetlands such as Botswana’s Okavango Delta, quantifying hydrology and ... -
Soil factors that influence the abundance and distribution of threatened and endangered species in the Okavango Delta; with particular emphasis on Eulophia angolensis
(Scientific Research Publishing, http://www.scirp.org, 2015-05-19)Eulophia angolensis is an endangered plant species found in the Okavango Delta. Generally, there is lack of botanical information on this species in Botswana, which is necessary for its in -situ and ex-situ conservation. ... -
Plant community response to loss of large herbivores differs between North American and South African savanna grasslands.
(Ecological Society of America; https://www.esa.org/esa/, 2014-04-01)Herbivory and fire shape plant community structure in grass‐dominated ecosystems, but these disturbance regimes are being altered around the world. To assess the consequences of such alterations, we excluded large herbivores ... -
