Nature and distribution of South African plinthic soils: Conditions for occurrence of soft and hard plinthic soils
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: P. A.L. le Roux --- Department of Soil, Crop and Climate Sciences, Republic of South Africa C.C. du Preez --- Department of Soil, Crop and Climate Sciences, Republic of South AfricaThe relevance of using redox morphology and irreversible hardened material to classify soft and hard plinthic soil forms is often questioned as the paleoclimate of South Africa varied significantly. Since the origin of the Soil Classification System of South Africa... -
ZOOPLANKTON AND ENVIRONMENTAL CONDITIONS IN GROENVLEI, SOUTHERN CAPE, DURING 1976
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: D.J. Coetzee --- Cape Department of Nature and Environmental Conservation, South AfricaThe zooplankton and environmental conditions in Groenvlei were studied during 1976 as part of an overall ecological study of the zooplankton of the Wilderness Lakes system. The Groenvlei water was found to be well mixed and low in dissolved PO4−P,... -
ZOOPLANKTON AND ESTUARINE RELICT (BENTHIC) FAUNA IN LAKE MZINGAZI, A FRESHWATER COASTAL LAKE OF NATAL
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: B.K. Fowles --- , South Africa C. G.M. Archibald --- , South AfricaLake Mzingazi, a natural, undisturbed freshwater coastal lake in the heart of the Richards Bay municipal area, is threatened by rapid urban and industrial growth. The previously unrecorded composition and distribution of zooplankton in the lake was studied during 1979... -
DISTRIBUTION AND ABUNDANCE OF THE BENTHOS IN THE SEDIMENTS OF LAKE CUBHU: A FRESHWATER COASTAL LAKE IN ZULULAND SOUTH AFRICA
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: D.P. Cyrus --- Coastal Research Unit of Zululand, Department of Zoology, South Africa T.J. Martin --- Coastal Research Unit of Zululand, Department of Zoology, South AfricaA preliminary investigation of the macrobenthic invertebrates of the sediments of Lake Cubhu, a freshwater coastal lake near Richards Bay was conducted on a quarterly basis during 1987. The most important factor which determined the abundance and distribution of each... -
PRELIMINARY OBSERVATIONS ON THE MACROCRUSTACEA OF COASTAL LAKES IN THE VICINITY OF RICHARDS BAY, ZULULAND, SOUTH AFRICA
Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences • Authors: P.E. Reavell --- Department of Botany, South Africa D.P. Cyrus --- Coastal Research Unit of Zululand, Department of Zoology, South AfricaA limited amount of research has been carried out on the four coastal lakes in the Richards Bay area. Due to the impending threat of water pollution from industrial, mining and residential areas within the catchments of these lakes there... -

Unconsolidated sediment distribution patterns in the KwaZulu-Natal Bight, South Africa: the role of wave ravinement in separating relict versus active sediment populations
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: AN Green --- Geological Sciences, School of Agricultural, Earth and Environmental Sciences, South Africa CF MacKay --- Oceanographic Research Institute, South AfricaThis paper examines the distribution of unconsolidated sediment in the KwaZulu-Natal Bight located along the east coast of South Africa. Results show that there is a general shelf-wide sediment distribution of coarser grain sizes between depths of 60 and 100 m,... -
Comparison of physiological responses to high temperatures in juvenile and adult Cape Rockjumpers Chaetops frenatus
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Krista N Oswald --- Department of Zoology, South Africa Alan TK Lee --- Fitzpatrick Institute of African Ornithology, DST/NRF Centre of Excellence, South Africa Ben Smit --- Department of Zoology, South AfricaConcerns about climate change have led to an increase in studies on physiological mechanisms birds possess to cope with increasing temperatures. For range-restricted species such as Cape Rockjumpers Chaetops frenatus, whose population declines are correlated with habitat warming, we identified...
