Unraveling the diversification and systematic puzzle of the highly polymorphic Psammobates tentorius (Bell, 1828) complex (Reptilia: Testudinidae) through phylogenetic analyses and species delimitation approaches
(Wiley-Blackwell, 2020)
The high level of phenotypic diversity in southern African tent tortoises (Psammobates tentorius complex) has for decades prevented systematists from developing a stable taxonomy for the group. Here, we used a comprehensive ...
Applying science to pressing conservation needs for penguins
(Wiley-Blackwell, 2020)
More than half of the world's 18 penguin species are declining. We, the Steering Committee of the International Union for Conservation of Nature Species Survival Commission Penguin Specialist Group, determined that the ...
Sampling bias in reptile occurrence data for the Kruger National Park
(OpenJournals Publishing AOSIS (Pty) Ltd, 2020)
To effectively conserve and manage species, it is important to (1) understand how they are spatially distributed across the globe at both broad and fine spatial resolutions and (2) elucidate the determinants of these ...
Effects of inorganic salt solutions on vigour, viability, oxidative metabolism and germination enzymes in aged cabbage and lettuce seeds
(MDPI, 2020)
This study assessed the potential of pre-hydration treatment with aqueous solutions
(electrolysed [cathodic water; CW] and non-electrolysed) prepared from four different inorganic
ion combinations: 1 mM CaCl2, 1 m CaCl2 ...
Neuroprotective activities of Boophone haemanthoides (amaryllidaceae) extract and its chemical constituents
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
Parkinson’s disease (PD) is a neurodegenerative condition that progresses as age increases, and some of its major symptoms include tremor and postural and movement-related difficulties. To date, the treatment of PD remains ...
How many species of angulate tortoises occur in Southern Africa? (Testudines: Testudinidae: Chersina)
(Wiley-Blackwell, 2020)
Using range-wide sampling and 1,143 bp of mtDNA (cytochrome b gene) and 14 microsatellite loci, we examined genetic differentiation in the widely distributed Southern African angulate tortoise (Chersina angulata). We found ...
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 ...
An assessment of the influence of host species, age, and thallus part on kelp-associated diatoms
(MDPI, 2020)
Diatom community composition and abundances on different thallus parts of adult and juvenile specimens of Ecklonia maxima and Laminaria pallida were examined in False Bay, South Africa, using light and scanning electron ...
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 ...
Nest-type associated microclimatic conditions as potential drivers of ectoparasite infestations in African penguin nests
(Springer Nature, 2020)
Nest design and characteristics can influence the microclimatic conditions in the nest. Nest-dwelling ectoparasites are sensitive to temperature and moisture and as such the conditions in the nest can influence parasite ...
