Abundance of the Indo-Pacific bottlenose dolphin Tursiops aduncus off south-west Mauritius
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: I Webster --- Mauritius Marine Conservation Society, Mauritius VG Cockcroft --- Centre for Dolphin Studies, Department of Zoology, South Africa A Cadinouche --- SEABIOME, MauritiusThe abundance of Indo-Pacific bottlenose dolphins Tursiops aduncus off the south-west coast of Mauritius was estimated using capture-mark-recapture modelling. Over the past two decades this population has been subjected to ongoing anthropogenic disturbance in the form of extensive coastal development... -
The nursery role of a sheltered surf-zone in warm-temperate southern Africa
Item type: Journal Article • Journal: African Zoology • Authors: Gavin M Rishworth --- Department of Zoology, Nelson Mandela Metropolitan University, South Africa Nadine A Strydom --- Department of Zoology, Nelson Mandela Metropolitan University, South Africa Warren M Potts --- Department of Ichthyology and Fisheries Science, Rhodes University, South AfricaMarine fish nurseries such as surf-zones have usually been classified as nurseries based solely on the density of pre-adult fish, yet the full suite of developmental stages are seldom assessed because of difficulties associated with sampling these habitats. The larval... -
Movement patterns of surf-zone fish species in a subtropical marine protected area on the east coast of South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: BQ Mann --- Oceanographic Research Institute, South Africa PD Cowley --- South African Institute for Aquatic Biodiversity, South Africa ST Fennessy --- Oceanographic Research Institute, South AfricaA long-term mark-recapture study was used to assess the movement patterns of surf-zone fishes in the St Lucia Marine Reserve, a marine protected area within the iSimangaliso Wetland Park, a World Heritage Site on the east coast of South Africa... -
The development of a scoring tool for the measurement of performance in managing hypotension and intra-operative cardiac arrest during spinal anaesthesia for caesarean section
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: Garth Horsten --- Discipline of Anaesthesia and Critical Care, Inkosi Albert Luthuli Central Hospital, Nelson R. Mandela School of Medicine, South Africa Robert Wise --- Pietermaritzburg Metropolitan Department of Anaesthetics, South Africa Shaun Ramroop --- Department of Statistics and Biometry, School of Mathematics, Statistics and Computer Science, South Africa Reitze Rodseth --- Pietermaritzburg Metropolitan Department of Anaesthetics, South AfricaBackground: At level one hospitals in South Africa a high annual number of maternal deaths occur due to the unrecognised/untreated complications of spinal anaesthesia. The authors developed a clinical scenario and scoring system to measure intern performance in managing hypotension... -
Movement behaviour of alien largemouth bass Micropterus salmoides in the estuarine headwater region of the Kowie River, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Taryn S Murray --- South African Institute for Aquatic Biodiversity, South Africa Mandla L Magoro --- South African Institute for Aquatic Biodiversity, South Africa Alan K Whitfield --- South African Institute for Aquatic Biodiversity, South Africa Paul D Cowley --- South African Institute for Aquatic Biodiversity, South AfricaThe movement behaviour of largemouth bass Micropterus salmoides in the estuarine headwater region of the Kowie River, South Africa, was investigated using passive acoustic telemetry. Ten adult fish were tagged and released in four discrete pools below a weir that... -
Bottlenose dolphin Tursiops truncatus group dynamics, site fidelity, residency and movement patterns in the Madeira Archipelago (North-East Atlantic)
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: A Dinis --- Madeira Whale Museum, Caniçal, Portugal F Alves --- Madeira Whale Museum, Caniçal, Portugal C Nicolau --- Madeira Whale Museum, Caniçal, Portugal C Ribeiro --- Madeira Whale Museum, Caniçal, Portugal M Kaufmann --- Centre of Life Sciences, Portugal A Cañadas --- ALNILAM – Research and Conservation, Spain L Freitas --- Madeira Whale Museum, Caniçal, PortugalThe bottlenose dolphin Tursiops truncatus is one of the most frequently sighted cetacean species in the Madeira Archipelago (North-East Atlantic); however, little is known about its population ecology in these waters. Photo-identification undertaken during systematic, non-systematic and opportunistic surveys conducted... -
Movement patterns and growth rate of the whitespotted wedgefish Rhynchobatus djiddensis in southern Africa based on tag-recapture data
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: GL Jordaan --- , South Africa BQ Mann --- , South Africa R Daly --- , South Africa SW Dunlop --- , South Africa PD Cowley --- , South AfricaInformation on the movement ecology of endangered species is critical for the implementation of effective conservation measures. This study made use of a long-term dart tagging dataset to reveal the movement patterns and growth rates of two size classes of... -
Residency, site affinity and coastal movements of the southern African endemic spotted gully shark Triakis megalopterus
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: E Cottrant --- South African Shark Conservancy, South Africa JH Morrison --- South African Shark Conservancy, South Africa C Elston --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa TS Murray --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa NJ Drobniewska --- South African Shark Conservancy, South Africa LG Underhill --- Department of Biological Sciences, University of Cape Town, South Africa N Hammerschlag --- Rosenstiel School of Marine, Atmospheric, and Earth Science, University of Miami, United States PS Albano --- Rosenstiel School of Marine, Atmospheric, and Earth Science, University of Miami, United States ME McCord --- South African Shark Conservancy, South Africa PD Cowley --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa C Fallows --- Apex Shark Expeditions, South Africa TG Paulet --- South African Shark Conservancy, South AfricaRising global concern regarding the conservation and management of shark species makes it essential to identify key ecological species to guide conservation efforts, especially species with more restricted distributions such as endemic species. The southern African endemic spotted gully shark...
