Genetic diversity of the Rattus complex (Rodentia: Muridae) in KwaZulu-Natal.
(2010)The rodent genus Rattus is considered to be the single largest genus of mammals in the world. One species of Rattus is usually more dominant than another within a specific geographical area; however within the province ... -
Genetic variability of Chaerephon atsinanana (Chiroptera) within the context of the Afro-Malagasy Molossidae : a mitochondrial and nuclear perspective.
(2013)This study has focused on genetic variability and structure in Chaerephon atsinanana, a newly-described molossid bat found in the mid to southern region of the eastern watershed of Madagascar. As these bats are strong ... -

Grasshopper ecology and conservation in the Nama-Karoo.
(2001)This study was undertaken in the Karoo, a semi-arid grazing land in South Africa, to elucidate the interaction between grasshopper assemblages and various aspects of the Karoo landscape. It falls into four sections, the ... -
Grasslands of Umtamvuna Nature Reserve, KwaZulu-Natal : a description and recommendations for monitoring.
(1995)The main aim of this study was to classify and map the threatened coastal grassland communities of the 3 257 ha Umtamvuna Nature Reserve (UNR) in KwaZulu-Natal (30°07'30" to 300 11'05"E; 30°55'00" to 31°04'30"S). Secondary ... -
Grazing management in the communal rangelands of the Upper Thukela, Kwazulu-Natal.
(2005)The grazing management project in the Okhombe ward of the Amazizi Tribal Authority formed part of the National Department of Agriculture's LandCare program to address communal natural resource management issues. Okhombe ... -
Growth and nutrient cycling in cultivated protea neriifolia R.Br.
(1991)The family Proteaceae is distributed predominantly in the south-western Cape Province of South Africa and south-western and south-eastern Australia, areas which fall within the climate term mediterranean ecosystems. A ... -
Growth and reproduction in the fruit bat Epomophorus wahlbergi.
(1983)This study was carried out on the Natal South Coast between 30° 12' S and 30° 19' S, where 1085 Epomophorous wahlbergii were caught by mist-netting, and a captive breeding colony was kept between June 1977 and February ... -
Growth characteristics of three Eucalyptus clonal hybrids in response to drought stress : the underlying physiology.
(2012)Previous research by Drew et al. (2009) on a SAPPI dendrometer trial, in northern KwaZulu-Natal, South Africa, yielded growth results for two Eucalyptus grandis clones (termed E. grandis x urophylla (GU) and E. grandis x ... -
Habitat quality effects on the ecology of leopard on a small enclosed reserve.
(2013)Although the leopard (Panthera pardus) is one of the more successful large carnivores, challenges for leopard conservation emulate those of other more endangered carnivores, and they are a model species for investigating ... -
Habitat use and feeding ecology of the roan antelope at Weenen Nature Reserve.
(1995)The roan antelope Hippotragus equinus equinus, is listed as endangered in the South African Red Data Book. A herd of nine roan were introduced to Weenen Nature Reserve (WNR) in 1988. The herd has since increased to ... -
