Descriptive epidemiology of and response to the high pathogenicity avian influenza (h5n8) epidemic in South African coastal seabirds, 2018
(Wiley, 2023)High pathogenicity avian infuenza (HPAI) clade 2.3.4.4b H5N8 virus was detected in coastal seabirds in late 2017 in South Africa, following a devastating epidemic in the commercial poultry and ostrich industries. By May ... -
Detecting marine heatwaves with sub-optimal data
(Frontiers, 2019)Marine heatwaves (MHWs), or prolonged periods of anomalously warm sea water temperature, have been increasing in duration and intensity globally for decades. However, there are many coastal, oceanic, polar, and sub-surface ... -
Determining the most appropriate feeding regime for the South African abalone Haliotis midae Linnaeus grown on kelp
(Springer Verlag, 2008)Beach-cast kelp (the most widely used feed for commercially grown South African abalone) is plentiful during winter months when periodic storms cause kelp to wash ashore. During summer, however, this resource is not ... -
Development of a compendium of local, wild-harvested species used in the informal economy trade, Cape Town, South Africa
(Resilience Alliance, 2012)Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural ... -
Diet and feeding in the Cape Cobra, Naja nivea
(Taylor & Francis, 2017)It is widely reported that African cobras (genus Naja) are generalist predators, but examination of formal literature yields relatively little evidence of this for most species. Here, we review the diet of cape cobras (Naja ... -
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 ... -
Diet of whale sharks Rhincodon typus inferred from stomach content and signature fatty acid analyses
(Inter Research, 2013)Whale sharks Rhincodon typus are large filter-feeders that are frequently observed feeding in surface zooplankton patches at their tropical and subtropical coastal aggregation sites. Using signature fatty acid (FA) ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(Wiley, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(John Wiley and Sons Inc, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African coastline, ... -
The diurnal activity budgets of extralimital giraffe (Giraffa camelopardalis giraffa) in the Western Cape Province, South Africa
(Wiley, 2023)Despite being an extralimital species in the region, South African giraffes (Giraffa camelopardalis giraffa, Schreber 1784) are continuously being introduced into the Albany Thicket Biome of the Western Cape Province of ... -
DNA sequencing reveals three new species of Chamberlainium (Corallinales, Rhodophyta) from South Africa, all formerly passing under Spongites yendoi
(De Gruyter Open Ltd, 2021)Three new non-geniculate coralline algal species from South Africa are described that were passing under the misapplied name, Spongites yendoi. Based on plastid encoded DNA sequences from psbA and rbcL markers, these species ... -
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 influence when a species is first described (the date of first description, DoFD) allows us to target environments and/or species' traits ... -

(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' ... -
Does the landscape functionality approach provide insight into rangeland conditions in the Tanqua Karoo region, South Africa?
(PeerJ, 2022)The harsh environmental conditions coupled with a long history of overgrazing have altered the ecology of the arid Tanqua Karoo rangelands in South Africa, which necessitates rehabilitation. However, a suitable method ... -
Don't cut that 'grass'
(Botanical Society of South Africa, 2006)Introduction: Have you ever noticed the abundance of wildflowers on public open spaces during spring in Cape Town? I suppose some Capetonians would be aware of Rondebosch Common and the astonishing botanical diversity ... -
DRIFT incorporating an eco-social system network and time series approach into environmental flow assessments
(Taylor & Francis, 2022)DRIFT (Downstream Response to Imposed Flow Transformation) is an interactive, ecological-social process and software package to assist with environmental flow assessments and river management decision-making. It was ... -
Early-life gut dysbiosis linked to juvenile mortality in ostriches
(Springer Nature, 2020)Imbalances in the gut microbial community (dysbiosis) of vertebrates have been associated with several gastrointestinal and autoimmune diseases. However, it is unclear which taxa are associated with gut dysbiosis, and if ... -
Ecological significance of deep-layer sloughing in the eulittoral zone coralline alga, Spongites yendoi (Foslie) Chamberlain (Corallinaceae, Rhodophyta) in South Africa.
(Elsevier, 1994)The crustose coralline alga Spongites yendoi (Foslie) Chamberlain (Corallinaceae, Rhodophyta) dominates the lower eulittoral zone along the South Coast of South Africa, together with the limpet Patella cochlear Born. This ... -
The effect of anthropogenic noise and weather conditions on male calls in the bladder grasshopper Bullacris unicolor
(Taylor and Francis Group, 2021)Acoustic communication in animals relies upon specificcontextsandenvironments for effective signal transmission. Increasing anthropo-genic noise pollution and different weather conditions can disruptacoustic communication. ... -
