Winter is coming: A southern hemisphere perspective of the environmental drivers of sars-cov-2 and the potential seasonality of covid-19
(MPDI, 2020)
SARS-CoV-2 virus infections in humans were first reported in December 2019, the boreal winter. The resulting COVID-19 pandemic was declared by the WHO in March 2020. By July 2020, COVID-19 was present in 213 countries and ...
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 ...
The effects of detergent and fertilizer toxicity on growth rate, nutrient utilization and survival of Clarias gariepinus (Burchell) fingerlings reared under controlled condition
(International Journal of Fisheries and Aquatic Studies, 2020)
Study on the effects of metals on growth rate and survival of Clarias gariepinus (Burchell 1822) fingerlings bred in tanks containing water concentrated with inorganic fertilizer and detergent was conducted. 300 fingerlings ...
Niche divergence corresponds to genetic differentiation within the parrot-beaked tortoise Homopus areolatus (Reptilia: Testudinidae), endemic to South Africa
(Linnean Society of London, 2020)
We assessed genetic differentiation and habitat suitability for Homopus areolatus during current and Last Glacial
Maximum (LGM) conditions. The ND4 locus retrieved two monophyletic mtDNA clades with lower diversity in ...
Creating opportunities through science symposia
(South African Assn. For The Advancement Of Science, 2020)
For most marine scientists, unless we work in the field of fisheries development or at the interface of science and policy,
it is rare to feel that we are making an impact on the lives of people in the wider community. ...
The implications of the reclassification of South African wildlife species as farm animals
(South African Assn. For The Advancement Of Science, 2020)
The Government Gazette No. 42464 dated 17 May 20191 amended Table 7 of the Animal Improvement Act (Act no. 62
of 1998), which lists breeds of animals, to include at least 32 new wild animal species, including 24 ...
Assessing the effects of in vitro imposed water stress on pineapple growth in relation to biochemical stress indicators using polynomial regression analysis
(AcademicPres, 2020)
Knowing the mechanisms that operate under water stress in commercial crops, particularly those that can affect productivity, such as phenolic or cell wall metabolism, is becoming increasingly important in a scenario of ...
Rhodolith bed discovered off the south African coast
(MDPI, 2020)
Rhodolith beds have not previously been recorded in South Africa. A multidisciplinary research effort used remote sampling tools to survey the historically unexplored continental shelf off the Eastern Cape coast of South ...
Sharing for science: High-resolution trophic interactions revealed rapidly by social media
(PeerJ, 2020)
Discrete, ephemeral natural phenomena with low spatial or temporal predictability are incredibly challenging to study systematically. In ecology, species interactions, which constitute the functional backbone of ecological ...
Changes in mangroves at their southernmost African distribution limit
(Elsevier, 2020)
Mangroves in South Africa occur at one of the most southerly locations in the world, which provides a unique opportunity to study their dynamic responses to anthropogenic and natural perturbations. The exposed high-energy ...
