Acoustic observations of jellyfish in the Namibian Benguela
(Inter-Research, 2001)Multi-frequency acoustic data (18, 38 and 120 kHz) were collected in conjunction with pelagic trawl sampling for gelatinous macrozooplankton during a cruise to the Namibian Benguela in September 1999. Sampling focused ... -
Beyond the jellyfish joyride and global oscillations: advancing jellyfish research
(Oxford University Press, 2013)There has been debate in the literature recently about increases in jellyfish populations in response to anthropogenic change, and this has attracted widespread media interest. Despite an international collaborative ... -
Carybdea branchi, sp. nov., a new box jellyfish (Cnidaria: Cubozoa) from South Africa.
(Magnolia Press, 2009)A common and conspicuous member of the medusan fauna of South Africa has been the subject of repeated taxonomic confusion. After having been mistakenly identified by earlier workers as either Carybdea alata or Tamoya ... -
Diet composition and some observations on the feeding ecology of the rhizostome Rhopilema nomadica in Israeli coastal waters
(Cambridge University Press, 2020)Since the mid-1980s, swarms of the rhizostome Rhopilema nomadica have been an annual phenomenon in Israeli Mediterranean coastal waters during the summer months. Despite its annual prominence and the potential impact on ... -
Hydromedusae off the Orange River Mouth, Southern Africa
(NISC (Pty) Ltd and Taylor& Francis, 2003)A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of ... -
A modern description of Crambionella stuhlmanni (Scyphozoa: Rhizostomeae) from St. Lucia Estuary, South Africa
(Cambridge University Press, 2011)A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species ... -
A new macromedusa from the coast of Mozambique: Aurelia mozambica sp. nov. (Scyphozoa: Ulmaridae)
(Magnolia Press, 2021)A new species of the cosmopolitan jellyfish genus Aurelia is described from the coastal waters of Mozambique using a combination of morphological, meristic and genetic information (COI and 18S). The species can be separated ... -
Phenological shift in swarming patterns of Rhopilema nomadica in the Eastern Mediterranean Sea
(Oxford University Press, 2020)Jellyfish (JF) swarms impact human wellbeing and marine ecosystems. Their global proliferation is a matter of concern and scientific debate, and the multitude of factors affecting (and affected by) their density and ... -
Role of jellyfish in the plankton ecosystem revealed using a global ocean biogeochemical model
(Copernicus GmbH, 2021)Jellyfish are increasingly recognised as important components of the marine ecosystem, yet their specific role is poorly defined compared to that of other zooplankton groups. This paper presents the first global ocean ... -
Trophic ecology of carnivorous zooplankton in the Benguela
(NISC and Taylor & Francis, 1992)Carnivorous zooplankton in the Benguela system have tended to be ignored by all but early taxonomists and a handful of recent researchers. An attempt is made here to address the importance of carnivores in this system but, ...
