Activity and feeding of Dotilla fenestrata (Brachyura: Ocypodidae) in a warm, temperate South African estuary
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: C Bulcao --- Department of Zoology and Entomology, South Africa AN Hodgson --- Department of Zoology and Entomology, South AfricaThe activity of and consumption of organic material by the sand-bubbler crab Dotilla fenestrata was studied over neap and spring tides on a sheltered sand bank close to the mouth of the warm, temperate Kowie Estuary, South Africa. Crabs emerged... -
Role of the sandprawn Callichirus kraussi as an ecosystem engineer in a South African temporarily open/closed estuary
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: TO Henninger --- Department of Zoology and Entomology, South Africa PW Froneman --- Department of Zoology and Entomology, South AfricaThe role of the sandprawn Callichirus kraussi as an ecosystem engineer was experimentally assessed using caging experiments over a four-month period in 2010 in the temporarily open/closed Kasouga Estuary on the south-eastern coast of South Africa. The sandprawn contributed to... -
Interactions between Zostera capensis, Callianassa kraussi and Upogebia africana: deductions from field surveys in Langebaan Lagoon, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: T Siebert GM BranchCallianassid sandprawns and eelgrasses have been postulated to have mutually negative effects on each other. The relationship between Callianassa kraussi and Zostera capensis was investigated in Langebaan Lagoon on the west coast of South Africa by correlative field surveys. Seven... -
Interactions between Zostera capensis and Callianassa kraussi: influences on community composition of eelgrass beds and sandflats
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: T Siebert GM BranchEelgrass beds have been postulated to support different faunal communities from unvegetated sandflats, in part because of the stabilisation of sediments in eelgrass beds and their destabilisation in sandflats due to bioturbation. More specifically, eelgrass beds have been hypothesised to...
