Best --- Percy FitzPatrick Institute of African Ornithology, DST/NRF Centre of Excellence, University of Cape Town, South Africa Colin G. Attwood --- MA-RE Institute, Zoology Department, South Africa Charlene da Silva --- Department of Agriculture, South Africa Stephen J. Lamberth --- Department of Agriculture, South AfricaCommercial fishing in False Bay, South Africa, began in the 1600s. Today chondrichthyans are regularly taken in fisheries throughout the bay. Using a combination of catch, survey and life history data, the occurrence and long-term changes in populations of chondrichthyans... -
Beyond Jaws: rediscovering the ‘lost sharks’ of southern Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: DA Ebert --- Pacific Shark Research Center, USA KE van Hees --- Pacific Shark Research Center, USASouthern Africa has one of the richest and most diverse chondrichthyan faunas in the world, comprising all 13 orders, 49 families, 111 genera and approximately 204 species. This represents nearly 20% of all known chondrichthyans, and includes 117 shark, 79... -
Molecular species identification and population genetics of chondrichthyans in South Africa: current challenges, priorities and progress
Item type: Journal Article • Journal: African Zoology • Authors: Aletta E Bester-van der Merwe --- Molecular Breeding and Biodiversity Group, Department of Genetics, South Africa Katie S Gledhill --- South African Shark Conservancy, South AfricaMolecular genetic techniques, such as DNA barcoding and genotyping, are increasingly being used to assist with the conservation and management of chondrichthyans worldwide. Southern Africa is a shark biodiversity hotspot, with a large number of endemic species. According to the... -

Predation on the St Joseph Callorhinchus capensis by Cape fur seals Arctocephalus pusillus pusillus in Namibia
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: RH Leeney --- Namibia Nature Foundation, Namibia N Dreyer --- Ocean Conservation Namibia, NamibiaChondrichthyans form an important part of marine food webs as top predators and mesopredators. However, little is known about chondrichthyans in Namibian waters and the roles they play in ecosystem function. During efforts to disentangle Cape fur seals Arctocephalus pusillus... -
