Ecophysiology and population dynamics of the alien invasive gastropod Tarebia granifera in the iSimangaliso Wetland Park, South Africa.
Tarebia granifera is a prosobranch freshwater gastropod from south-east Asia which has invaded other sub-tropical parts of the world. This snail has recently also invaded the iSimangaliso Wetland Park, often reaching ...
Integrated physiology and behaviour of Thallomys nigricauda along an aridity gradient.
Climate change predictions suggest that the continent most vulnerable to climate change is Africa. The impacts of potential changes which include increases in air temperatures and rainfall variability are negative with ...
The invasive potential of the freshwater snail Radix rubiginosa recently introduced into South Africa.
Invasions of ecosystems by exotic species are increasing and they may often act as a significant driver of the homogenization of the Earth’s biota, resulting in global biodiversity loss. Moreover, the addition of exotic ...
Patterns of animal endemism in the Maputaland-Pondoland-Albany biodiversity hotspot.
The Maputaland-Pondoland-Albany (MPA) hotspot, as is the case of all such global biodiversity hotspots, has primarily been recognised based on its high floristic endemism and delimited intuitively. Boundaries of global ...
Studies on the biology of three species of sea urchin (Echinodermata : Echnoidea), on the South African east coast.
Ten species of shallow water echinoid are found on the subtropical east coast of South Africa. Although their distributions are patchy, the most common species, Echinometra mathaei, stomopneustes variolaris and Diadema ...
Biological studies of bottlenose dolphins from Natal coastal waters.
The biology of bottlenose dolphins from the east coast of southern Africa is investigated. Births occur predominantly in summer, after a one year gestation period. Calves are born at a length of approximately 103 cm and ...
Two aspects of the biology of an African honeybee, Apis mellifera scutellata (Hymenoptera, Apidae) : laying workers, and colony defence behaviour.
Abstract available in PDF file.
The biology and systematic relationships of Crowned, Blackwinged and Lesser Blackwinged Plovers.
Plovers was compared with particular reference to breeding biology, feeding ecology and habitat preference. Crowned and Blackwinged Plovers coexisted in mixed flocks in grasslands which aided predator detect ion and ...
Aspects of the biology, specific status and control of the bedbugs Cimex lectularius and Cimex hemipterus in northern Natal and KwaZulu.
The bedbugs Cimex lectularius and C. hemipterus (Hemiptera: Cimicidae) have been identified from a study area in northern Natal and KwaZulu. South Africa, between 26° 45' S and 28° 45' S, and 32° 00 ' E and 32° 52' E. ...
The freshwater Diaptomidae (Calanoida : Copepoda) of Southern Africa.
Freshwater copepod taxonomy has been neglected in southern Africa for more than 50 years and this has placed a constraint on research on the biology and ecology of this important component of the freshwater ...
