A NOTE ON SALINITY AND OXYGEN STRATIFICATION IN THE MARINA DA GAMA, ZANDVLEI
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: B.R. Davies --- Zoology Department, Republic of South Africa B.A. Stewart --- Zoology Department, Republic of South AfricaTen months data (March to December, 1983), on temperature, salinity and dissolved oxygen are reported for two canals within the Marina Da Gama, Zandvlei, a coastal lake periodically open to the sea. They show that although there was minimal temperature... -
Historic and recent (2006) state of mangroves in small estuaries from Mlalazi to Mtamvuna in KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: A Rajkaran --- Botany Department, South Africa J Adams --- Botany Department, South Africa R Taylor --- , South AfricaThe new forest type classification considers mangroves to be the rarest and most threatened of forest types in South Africa. The aim of this study was to determine the change in distribution and the current population and community structure of... -
Seasonal changes of nutrient levels and nutrient resorption in Avicennia marina leaves in Yingluo Bay, China
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Shudong Wei --- College of Life Sciences, China Xiaowei Liu --- Key Laboratory of the Ministry of Education for Coastal and Wetland Ecosystems, School of Life Sciences, China Lihua Zhang --- Key Laboratory of Coastal Environmental Processes and Ecological Remediation, China Hui Chen --- College of Life Sciences, China Hui Zhang --- Key Laboratory of the Ministry of Education for Coastal and Wetland Ecosystems, School of Life Sciences, China Haichao Zhou --- Key Laboratory of the Ministry of Education for Coastal and Wetland Ecosystems, School of Life Sciences, China Yiming Lin --- Key Laboratory of the Ministry of Education for Coastal and Wetland Ecosystems, School of Life Sciences, ChinaAvicennia marina is a typical mangrove species of subtropical coastlines of China. However, little is known about the retention of nutrients by this species in oligotrophic, coastal environments. In this study, seasonal changes in nitrogen (N) and phosphorus (P) concentrations,... -
Spatial and temporal variability in the larval fish assemblage of a warm temperate South African estuary, with notes on the effects of artificial channelling
Item type: Journal Article • Journal: African Zoology • Authors: M. Kruger --- Department of Ichthyology and Fisheries Science, South Africa N.A. Strydom --- South African Institute for Aquatic Biodiversity, South AfricaThe composition, abundance, distribution and seasonality of larval fishes was investigated in the permanently open Kowie Estuary on the temperate southeast coast of South Africa. Larval fishes were sampled within the estuary and marina for a period of two years... -
Dropping plates to pick up aliens: towards a standardised approach for monitoring alien fouling species
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: TG Loureiro --- , South Africa K Peters --- , South Africa TB Robinson --- , South AfricaBiological invasions pose a major threat to biodiversity and significant investment is required to prevent the introduction of alien species, contain introduced populations and mitigate associated impacts. The implementation of standardised long-term monitoring programmes enables the early identification of new... -
Long-term changes in petrel populations on Inaccessible Island, Tristan da Cunha, inferred from the diet of Brown Skuas Stercorarius antarcticus
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Peter G Ryan --- University of Cape Town, South AfricaPetrels that breed in burrows and return to their colonies after dark are among the most poorly studied seabirds. Brown Skuas Stercorarius antarcticus (family Stercorariidae) are major predators of burrowing petrels at many seabird breeding islands in the Southern Ocean,...
