Self-maintaining or continuously refreshed? The genetic structure of Euphausia lucens populations in the Benguela upwelling ecosystem
(Oxford University Press, 2013)
Populations of Euphausia lucens over the shelf of the southern Benguela upwelling region could be self-maintaining. Alternatively, they could be continually refreshed by expatriates from the SW Atlantic that enter the ...
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 ...
Feeding and vertical migration of the chaetognath Sagitta friderici (Ritter Zahony, 1911) in the southern Benguela during spring 1987, with notes on seasonal variability of feeding ecology
(NISC and Taylor & Francis, 1994)
The feeding biology and the vertical migration of Sagitta friderici were examined over 24 h at two stations in the southern Benguela during spring (October) 1987. Together with studies conducted during summer (February ...
New observations on the diel vertical distribution of Hydromedusae in the southern Benguela ecosystem
(NISC (Pty) Ltd and Taylor& Francis, 2003)
Diel vertical migration (DVM) of six common species of hydromedusae was investigated during two drogue studies conducted in St Helena Bay on the west coast of South Africa in February 1995. Clytia spp., Obelia spp. and ...
Observations on the pelagic decapod Pasiphaea semispinosa in the Benguela upwelling ecosystem
(NISC and Taylor & Francis, 1994)
Information on vertical and horizontal distribution patterns, abundance and morphology of the decapod Pasiphaea semispinosa in the Benguela upwelling system is presented. P. semispinosa is the dominant pelagic decapod in ...
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, ...
Self-maintaining or continuously refreshed? The genetic structure of Euphausia lucens populations in the Benguela upwelling ecosystem
(Oxford University Press, 2013)
Populations of Euphausia lucens over the shelf of the southern Benguela upwelling
region could be self-maintaining. Alternatively, they could be continually refreshed
by expatriates from the SWAtlantic that enter the ...
Does phylogeny have an influence on the date of first description? A comparative study of the world's fishes
(Elsevier, 2020)
The process of species description is not random, and understanding the factors that in-
fluence when a species is first described (the date of first description, DoFD) allows us to
target environments and/or species' ...
Null models for null hypotheses in taxonomy: A test using Scyphozoa
(Oxford University Press, 2021)
Although molecular tools are becoming more important in the delineation of scyphozoan species there is,
perforce, a need to substantiate new species definitions using morphological data. Access to type material
is often ...
Mesoscale structure of neuston assemblages across the southern Indian Ocean subtropical gyre
(Elsevier, 2022-12-28)
Despite concern around plastic pollution in subtropical gyres, our understanding of the biological component of
the neustonic layer (upper 20 cm of the ocean) in these areas is poor. Here we investigate the neuston ...
