Of sea bamboo, split fan kelp and bladder kelp: three common kelp species of the Cape Peninsula and West Coast
(Botanical Society of South Africa, 2001)The third part in our series on the common intertidal seaweeds of the Cape Peninsula looks at the kelps, the giant brown seaweeds that occur in the subtidal and intertidal gullies of the Cape Peninsula and the west coast. ... -
Of sea lettuces and green sea intestines: common intertidal green seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2000)Most of us know seaweed as that slippery stuff growing on the rocks or lying strewn along the beach at low tide making the beach smell. But do we really know much about them? Although not entirely true, seaweeds (or marine ... -
Oligosaccharides production from coprophilous fungi: An emerging functional food with potential health-promoting properties
(Elsevier, 2022)Functional foods are essential food products that possess health-promoting properties for the treatment of infectious diseases. In addition, they provide energy and nutrients, which are required for growth and survival. ... -
Opportunities for improving recognition of coastal wetlands in global ecosystem assessment frameworks
(Elsevier, 2021)Vegetated coastal wetlands, including seagrass, saltmarsh and mangroves, are threatened globally, yet the need to avert these losses is poorly recognized in international policy, such as in the Convention on Biological ... -
Othonna koos-bekkeri Van Jaarsv. is a synonym of Othonna cerarioides Magoswana & J.C.Manning (Asteraceae: Othonninae)
(AOSIS (pty) Ltd, 2021-10-18)Othonna koos-bekkeri Van Jaarsv. is recognised as a synonym of O. cerarioides Magoswana & J.C.Manning. Copyright: © 2021. The Authors -
Oxidative Stress, Ageing and Methods of Seed Invigoration: An Overview and Perspectives
(MDPI, 2021)The maintenance of seed quality during the long-term conservation of plant genetic resources is crucial for averting the projected food crises that are linked to the changing climate and rising world population. However, ... -
Pathways towards coexistence with large carnivores in production systems
(Springer, 2021)Coexistence between livestock grazing and carnivores in rangelands is a major challenge in terms of sustainable agriculture, animal welfare, species conservation and ecosystem function. Many effective non-lethal tools exist ... -
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 ... -
Phylogenetic placement and generic re-circumscriptions of the multilocular genera Arenifera, Octopoma and Schlechteranthus (Aizoaceae: Ruschieae): Evidence from anatomical, morphological and plastid DNA data
(International Association for Plant Taxonomy (IAPT), 2016)"Ruschieae is the largest tribe in the highly speciose subfamily Ruschioideae (Aizoaceae). A generic-level phylogeny for the tribe was recently produced, providing new insights into relationships between the taxa. Octopoma ... -
Phylogenetic position and revised classification of Acacia s.l. (Fabaceae: Mimosoideae) in Africa, including new combinations in Vachellia and Senegalia
(Oxford University Press, 2013)Previous phylogenetic studies have indicated that Acacia Miller s.l. is polyphyletic and in need of reclassification. A proposal to conserve the name Acacia for the larger Australian contingent of the genus (formerly ... -
Phylogeographic investigation of the bladder grasshopper Bullacris unicolor (Orthoptera Pneumoroidea) in South Africa
(Taylor and Francis Group, 2023)There are several factors, such as genetic drift, gene flow and migration that affect the population genetic structure and phylogeographic distribution of genetic lineages within single species. Previous studies of the ... -
A phytogeographical classification and survey of the indigenous browse flora of South Africa, Lesotho, and eSwatini
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Rangelands in South Africa, Lesotho, and Eswatini contain a rich diversity of valuable fodder trees and shrubs. This research is the first attempt to document the regional diversity and distribution of these browse resources. ... -
Pineapple stem-derived bromelain based priming improves pepper seed protein reserve mobilization, germination, emergence and plant growth
(Springer, 2021)Pepper seeds are slow to germinate and emergence is often non-uniform and incomplete, reducing gains from this cash crop. This study investigated the effects of pineapple stem- derived protease (stem bromelain) based priming ... -
Plastic ingestion by estuarine mullet Mugil cephalus (Mugilidae) in an urban harbour, KwaZulu-Natal, South Africa
(National Inquiry Services Centre (NISC), 2016)Coastal urban environments have high plastic pollution levels, and hence interactions between plastic debris and marine life are frequent. We report on plastic ingestion by mullet Mugil cephalus in Durban Harbour, ... -
Population ecology of Psammobates oculifer in a semi-arid environment
(Taylor & Francis and UNISA Press, 2013)We studied the ecology of Psammobates oculifer over 13 months near Kimberley, South Africa, to ascertain if the population’s life history traits conform to chelonian patterns in arid environments. Capture rates were highest ... -
Porolithon improcerum (porolithoideae, corallinaceae) and mesophyllum macroblastum (melobesioideae, hapalidiaceae): New records of crustose coralline red algae for the Southwest Atlantic Ocean
(Magnolia Press, 2014)Here we describe in detail two crustose coralline red algal (CCA) species newly reported for the southern Atlantic: Porolithon improcerum and Mesophyllum macroblastum. Porolithon improcerum was recorded on the remote ... -
Possible aquaculture development in Nigeria: evidence for commercial prospects
(David Publishing, 2017)The cultivation of desirable aquatic organisms is becoming increasingly important as one of the fastest-growing agro-industrial activities in the world. Nigeria, over the years, practised traditional methods of aquaculture ... -
Predicting Shifts in the geographical distribution of two estuarine plant species from the subtropical and temperate regions of South Africa
(Springer, 2019-11-21)Climate suitability maps are useful to determine changes in the distribution of species. The aim of this study was to predict the future distribution of two estuarine species (Bassia diffusa and Hibiscus tiliaceus) from ... -
Predominant atmospheric and oceanic patterns during coastal marine heatwaves
(Frontiers Media, 2017)As the mean temperatures of the worlds oceans increase, it is predicted that marine heatwaves (MHWs) will occur more frequently and with increased severity. However, it has been shown that variables other than increases ... -
Protect high seas biodiversity
