Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH)
(BMC, 2018)
BACKGROUND: The specialist-generalist variation hypothesis (SGVH) in parasites suggests that, due to patchiness in
habitat (host availability), specialist species will show more subdivided population structure when compared ...
The Galactic halo pulsar population
(Oxford University Press, 2018)
Most population studies of pulsars have hitherto focused on the disc of the Galaxy, the

Closure, interior and neighbourhood in a category
(Hacettepe University, 2018)
The natural correspondences in topology between closure, interior
and neighbourhood no longer hold in an abstract categorical setting
where subobject lattices are not necessarily Boolean algebras. We
analyse three ...
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 ...
Leisure athletes at risk of medical complications: outcomes of pre-participation screening among 15,778 endurance runners - SAFER VII
(Taylor & Francis, 2018)
OBJECTIVE: International guidelines for pre-participation screening of masters/leisure athletes to identify those that require medical assessment exist, but have not been implemented in mass-community based sports events. ...
Antimicrobial resistant Gram-positive cocci in pregnant mothers with aerobic vaginitis
(Infection Control Africa Network (ICAN), 2016)
The vaginal microbiota of a healthy asymptomatic woman consists of an extensive diversity of anaerobic and aerobic bacterial genera and species dominated by the microaerophilic genus Lactobacillus , known to inhibit the ...
Correlates of early sexual debut and its associated STI/HIV risk factors among sexually active youths in Malawi
(SAGE Publications, 2017)
This study explores the correlates of early sexual debut and risk factors of sexually transmitted infections (STIs) among the youth in Malawi. Data was obtained from the Malawi Demographic Health Survey 2010. Out of a ...
