(National Association for Clean Air, 2018)Radon-222 measurements at Cape Point: A characterization of a 15-year time series The Cape Point (CPT) Global Atmosphere Watch (GAW) research station have been monitoring climatically significant trace ... -
Critical self-assembly concentration of bolaamphiphilic peptides andpeptide hybrids determined by fluorescence measurements
(University of KwaZulu-Natal, 2013)The study of the self-assembly properties of peptides and proteins is important for the understanding of molecular recognition processes and for the rational design of functional biomaterials. Novel bolaamphiphilic peptides ... -
The development and refinement of a questionnaire on the investigation of students' experience of first-year chemistry practicals
(University of KwaZulu-Natal, 2013)This article reports on the development and refinement of a questionnaire for first-year Chemistry students. Three subscales were probed, namely affective attitudes, perceptions towards tutor effectiveness and outcomes achieved. -
A simple ecological model captures the transmission pattern of COVID-19 outbreak in China
(BioMed Central, 2020)Background The rapid spread of the 2019 novel coronavirus disease (COVID-19), initially reported in the city of Wuhan in China, and quickly transmitted to the entire nation and beyond, has become an international ... -
MicroCT imaging applied to description of a new species of Pagurus Fabricius, 1775 (Crustacea: Decapoda: Anomura: Paguridae), with selection of three-dimensional type data
(Public Library of Science, 2018)A new species of hermit crab, Pagurus fraserorum n. sp. (family Paguridae) is described from rocky subtidal reefs off KwaZulu-Natal, South Africa, and illustrated using both conventional drawings and colour photographs, ... -
Wavelet signatures of K-splitting of the Isoscalar Giant Quadrupole Resonance in deformed nuclei from high-resolution (p, p ) scattering off ¹⁴⁶,¹⁴⁸,¹⁵⁰Nd
(Elsevier, 2018)The phenomenon of fine structure of the Isoscalar Giant Quadrupole Resonance (ISGQR) has been studied with high energy-resolution proton inelastic scattering at iThemba LABS in the chain of stable even-mass Nd isotopes ... -
Monitoring consumptive resource use in South African national parks
(AOSIS, 2019-01-30)Monitoring is an essential component of measuring the performance of protected areas. This requirement led to the development of a biodiversity monitoring system for South African National Parks (SANParks). The system ... -
All-in-one : physics, chemistry and ecology are essential fields to thermal ecologists
(International Biogeography Society, 2018)The book clearly targets principles that are essential for understanding the relationship between temperature and organisms and does not represent a book for applications on how to do measurements or complex tasks in thermal ... -
Frontiers of Biogeography : taking its place as a journal of choice for the publication of high quality biogeographical research articles
(International Biogeography Society, 2018)Through this editorial we seek your support and engagement as authors, readers and reviewers as we take the next steps in developing Frontiers of Biogeography as a leading international journal of biogeography and ... -
Why does not the leaf weight-area allometry of bamboos follow the 3/2-power law?
(Frontiers Media, 2018)The principle of similarity (Thompson, 1917) states that the weight of an organism follows the 3/2-power law of its surface area and is proportional to its volume on the condition that the density is constant. However, the ... -
Spatial segregation facilitates the coexistence of tree species in temperate forests
(MDPI, 2018)Competition between plants has an important role during the natural succession of forest communities. Niche separation between plants can reduce such interspecific competition and enable multispecies plant to achieve ... -
Koedoe : African Protected Area Conservation and Science - a retrospection : 1958 to 2018
(AOSIS, 2019-04-08)In 2018, Koedoe celebrated an unbroken publication record of 60 years. From uncertain beginnings in 1958, it is now a mature and important internationally recognised scientific journal focussing on conservation and science ... -
Decreased efficacy of doxorubicin corresponds with modifications in lipid metabolism markers and fatty acid profiles in breast tumors from obese vs. lean mice
(Frontiers Media, 2018-03-17)Breast cancer cells modulate lipid and fatty acid metabolism to sustain proliferation. The role of adipocytes in cancer treatment efficacy remains, however, to be fully elucidated. We investigated whether diet-induced ... -
GlobTherm, a global database on thermal tolerances for aquatic and terrestrial organisms
(Nature Research, 2018-03-13)How climate affects species distributions is a longstanding question receiving renewed interest owing to the need to predict the impacts of global warming on biodiversity. Is climate change forcing species to live near ... -
GloPL, a global data base on pollen limitation of plant reproduction
(Nature Research, 2018-11-20)Plant reproduction relies on transfer of pollen from anthers to stigmas, and the majority of flowering plants depend on biotic or abiotic agents for this transfer. A key metric for characterizing if pollen receipt is ... -
Coordinated autophagy modulation overcomes glioblastoma chemoresistance through disruption of mitochondrial bioenergetics
(Nature Research, 2018-07-09)Glioblastoma Multiforme (GBM) is known to be one of the most malignant and aggressive forms of brain cancer due to its resistance to chemotherapy. Recently, GBM was found to not only utilise both oxidative phosphorylation ... -
Temperature and monsoon tango in a tropical stalagmite : last glacial- Interglacial climate dynamics
(Nature Research, 2018)High-resolution paleoclimate data on stable isotopes in a stalagmite were coupled to glycerol dialkyl glycerol tetraethers (GDGTs). The Indian Summer Monsoon (ISM) transitioned from limited rainfall during the Last Glacial ... -
Correlative Light-Electron Microscopy detects lipopolysaccharide and its association with fibrin fibres in Parkinson’s Disease, Alzheimer’s Disease and Type 2 Diabetes Mellitus
(Nature Research, 2018-11-14)Many chronic diseases, including those classified as cardiovascular, neurodegenerative, or autoimmune, are characterized by persistent inflammation. The origin of this inflammation is mostly unclear, but it is typically ... -
Geographic variation and plasticity in climate stress resistance among southern African populations of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae)
(Nature Research, 2018-06-29)Traits of thermal sensitivity or performance are typically the focus of species distribution modelling. Among-population trait variation, trait plasticity, population connectedness and the possible climatic covariation ... -
