The potential for zoobenthic fauna dispersal into the St Lucia Estuary from the Mfolozi–Msunduzi estuarine system, KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: RK Owen --- Coastal Research Unit of Zululand, Department of Zoology, South Africa DP Cyrus --- Coastal Research Unit of Zululand, Department of Zoology, South Africa L Vivier --- Coastal Research Unit of Zululand, Department of Zoology, South Africa HL Jerling --- Coastal Research Unit of Zululand, Department of Zoology, South AfricaThe onset of a prolonged drought in the St Lucia catchment in 2002 and subsequent mouth closure raised concern for the biota of the estuary. Ezemvelo KZN Wildlife proposed a scheme whereby the Mfolozi–Msunduzi mouth would be closed, causing fresh... -
Spatial variability of macrozoobenthic diversity on tidal flats of the Niger Delta, Nigeria: the role of substratum
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: N Zabbey --- Department of Animal Science and Fisheries, Nigeria AI Hart --- Department of Animal and Environmental Biology, NigeriaBaseline community assemblages and diversity of macrozoobenthic infauna in soft-bottomed intertidal flats at Bodo Creek on the upper reaches of the Andoni–Bonny estuarine system were determined spatially and in relation to sediment particle characteristics for two years from May 2006... -
A review of the ecology and management of temporarily open/closed estuaries in South Africa, with particular emphasis on river flow and mouth state as primary drivers of these systems
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: AK Whitfield --- , South Africa GC Bate --- Department of Botany, South Africa JB Adams --- Department of Botany, South Africa PD Cowley --- , South Africa PW Froneman --- Department of Zoology and Entomology, South Africa PT Gama --- Department of Botany, South Africa NA Strydom --- Department of Zoology, South Africa S Taljaard --- , South Africa AK Theron --- , South Africa JK Turpie --- , South Africa L van Niekerk --- , South Africa TH Wooldridge --- Department of Zoology, South AfricaResearch in South African temporarily open/closed estuaries that includes studies on the hydrodynamics, sediment dynamics, macronutrients, microalgae, macrophytes, zoobenthos, hyperbenthos, zooplankton, ichthyoplankton, fishes and birds is used as a basis to review the ecology and management of this estuary type... -
Macrozoobenthic biodiversity patterns in the northern province of the Benguela upwelling system
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: ML Zettler --- Department of Biology, Germany R Bochert --- Department of Biology, Germany F Pollehne --- Department of Biology, GermanyThis paper describes macrozoobenthos diversity in the vicinity of the Angola–Benguela Frontal Zone between 15° and 23° S in offshore waters of the Namib biogeographic province in a comprehensive zoogeographical context. At 38 selected stations, about 500 different macrozoobenthic taxa... -
Macrozoobenthic communities in waters off Angola
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: G Lange --- Leibniz Institute for Baltic Sea Research, Germany A Darr --- Leibniz Institute for Baltic Sea Research, Germany ML Zettler --- Leibniz Institute for Baltic Sea Research, GermanyMacrozoobenthic biodiversity is described for waters off Angola, one of the poorest-known marine environments of the world. During research cruises in 2004 and 2011, the shelf region of Angola was investigated at 39 stations in water depths of between 19... -
Subtidal macrozoobenthic community resilience to change following natural mouth breaching of the temporarily open/closed East Kleinemonde Estuary, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: TH Wooldridge --- Department of Zoology, South Africa K Bezuidenhout --- Department of Zoology, South AfricaThe East Kleinemonde Estuary, on the south-east coast of South Africa, typically opens for only short periods, usually <10 days. During a nine-month study in 2006, marine influence persisted for a near-continuous period of three months. This provided an opportunity... -
Distribution and feeding modes of macrobenthos within three oceanographic feature areas of the KwaZulu-Natal Bight, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: CB Untiedt --- Oceanographic Research Institute, South Africa CF MacKay --- Oceanographic Research Institute, South AfricaThe composition and distribution of macrobenthic communities was investigated in three areas in the KwaZulu- Natal Bight, a section of shelf off the east coast of South Africa. Areas were pre-selected on the basis of three known oceanographic features, posited... -
The bivalve Lembulus bicuspidatus may enhance denitrification in shelf sediment at the Angola–Benguela Frontal Zone
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: A Neumann --- University of Hamburg, Institute for Geology, Germany A Flohr --- Leibniz Center for Tropical Marine Ecology, GermanyWe collected living individuals of the bivalve Lembulus bicuspidatus, which shows an unusual preference for the oxygen-deficient habitat found at the Angola–Benguela Frontal Zone of the southeastern Atlantic. With a series of incubation experiments with 15N-labelled nitrate as a tracer... -
Benthic macrofaunal changes in response to restoration efforts in the St Lucia estuarine lake, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: PC Moloi --- School of Agriculture and Science, University of KwaZulu-Natal, South Africa GM Rishworth --- Department of Zoology, Institute for Coastal and Marine Research, Nelson Mandela University, South Africa MS Bird --- Department of Zoology, University of Johannesburg, South Africa NK Carrasco --- School of Agriculture and Science, University of KwaZulu-Natal, South AfricaThe St Lucia estuarine lake and Mfolozi River mouth on the Indian Ocean coast of South Africa were once a single, connected system but were artificially separated in 1952 to prevent siltation from the Mfolozi River catchment which risked shallowing...
