The validity of currently recognised sectional limits within Combretum Loefling, subgenus Combretum (Combretaceae) in Southern Africa.
(1990)Taxonomic confusion associated with Combretum Loefling, subgenus Combretum (Combretaceae) resulted in this investigation into the validity of sectional limits within the subgenus in southern Africa. Eight sections, together ... -
Varying degrees of fear : how do large herbivores adjust their anti-predator behaviour in response to different predators?
(2016)Large predators are returning to areas where they have previously been absent through both predator reintroductions and natural range expansion. As a result, these re/introductions are changing the nature of predator-prey ... -
Varying soil nutrition in grassland and savanna ecosystems affect plant-microbe symbiosis, nitrogen nutrition and growth of Pisum sativum L.
(2019)Abstract available in pdf. -
Vegetation and ant dynamics in the southern Karoo.
(1997)The aim of this thesis was to describe the structure and dynamics of ant and plant communities in the southern Karoo and to assess mechanisms of species coexistence in ant and plant communities. The role of species ... -
Vegetation change in Northern KwaZulu-Natal since the Anglo-Zulu war of 1879.
(2013)Historic photographs have been successfully used to compare landscape change over time. I used photographs taken of the grassland biome during and just after the Anglo-Zulu War (1879) in KwaZulu-Natal (South Africa), which ... -
Vegetation change over fifty years in humid grasslands of KwaZulu-Natal (Acocks's sites)
(1997)Eighty three of Acocks's sites, originally surveyed about 50 years ago, were resurveyed in 1996 to determine the extent of grassland change in the humid grasslands of KwaZulu-Natal. Sites were relocated using 1:10 000 ... -
Vegetation succession and soil properties following the removal of pine plantations on the eastern shores of Lake St Lucia, South Africa.
(1998)Pine plantations have been established on secondary grassland on the dune systems of the Eastern Shores of Lake St Lucia, KwaZulu-Natal, South Africa for the past 40 years. These plantations have been progressively felled ... -

Warning vocalisations and predator information transfer in social birds.
(2008)Alarm or warning vocalizations are produced by many animals when they detect a potential predator. However little is known about the information contained in these vocalizations. This study investigated the warning ... -
Water stress effects on growth, development, resource capture and resource use efficiency of two contrasting sugarcane genotypes.

Waterborne sanitation, cost recovery and quality of life : a case study of Ekuvukeni
(1997)A bucket sanitation system is being replaced by waterborne sanitation at an apartheid created town called Ekuvukeni near Ladysmith in KwaZulu Natal. This study examines the reasons for upgrading sanitation at Ekuvukeni ... -
What drives the seasonal movements of african elephants (Loxodonta africana) in Ithala Game Reserve?
(2013)The changes in plant quality and availability in space and time present a substantial problem to mammalian herbivores. As a result, these herbivores need to alter their foraging behaviour to maximize their energy gain at ... -
Wildlife rehabilitation in South Africa.
(2009)Wildlife rehabilitation, defined as “providing temporary care to injured, ill and orphaned wild animals with the goal of releasing them back into their natural habitat”, developed in response to the increase in human ... -
Y-STR studies of genetic genealogy, population and forensic genetics of Indian and Zulu groups in the Durban, KwaZulu-Natal area of South Africa.
(2018)The combination of molecular genetics and surname analysis of short tandem repeat (STR) data has the potential to shed light on population structure and history, falling within the field of forensic deoxyribonucleic acid ...
