Laboratory X-ray micro-computed tomography : a user guideline for biological samples
(Oxford University Press, 2015)Laboratory X-ray micro-computed tomography (micro-CT) is a fast growing method in scientific research applications that allows for non-destructive imaging of morphological structures. This paper provides an easily operated ... -
Lake Tanganyika - a melting pot of ancient and young cichlid lineages (teleostei: cichlidae)?
(Public Library of Science, 2015)A long history of research focused on the East Africa cichlid radiations (EAR) revealed discrepancies between mtDNA and nuclear phylogenies, suggesting that interspecific hybridisation may have been significant during the ... -
Ledebouria caesiomontana A.J.Hankey & N.Hahn (Hyacinthaceae: Hyacinthoideae) : a new species from the Blouberg centre of endemism, Limpopo, South Africa
(AOSIS Publishing, 2014)Background: Ledebouria Roth (Hyacinthaceae: Hyacinthoideae) is a largely African genus with, more or less, 40 species occurring in South Africa. The species was first collected in December 1990 by R. Archer [Archer, R.H. ... -
Life cycle of Renylaima capensis, a brachylaimid trematode of shrews and slugs in South Africa : two-host and three-host transmission modalities suggested by epizootiology and DNA sequencing
(BioMed Central, 2012-08)Abstract Background The life cycle of the brachylaimid trematode species Renylaima capensis, infecting the urinary system of the shrew Myosorex varius (Mammalia: Soricidae: Crocidosoricinae) in the Hottentots Holland Nature ... -
Life-history traits evolved jointly with climatic niche and disturbance regime in the genus leucadendron (proteaceae)
(University of Chicago Press, 2017-12-05)ENGLISH ABSTRACT: Organisms have evolved a diversity of life-history strategies to cope with variation in their environment. Persistence as adults and/or seeds across recruitment events allows species to dampen the effects ... -
Limited genomic consequences of hybridization between two African clawed frogs, Xenopus gilli and X. laevis (Anura: Pipidae)
(Nature Research, 2017-04-24)The Cape platanna, Xenopus gilli, an endangered frog, hybridizes with the African clawed frog, X. laevis, in South Africa. Estimates of the extent of gene flow between these species range from pervasive to rare. Efforts ... -
Lizard epidermal gland secretions I : chemical characterization of the femoral gland secretion of the sungazer, Cordylus giganteus
(Springer Verlag, 2007-09)The giant girdled lizard or sungazer, Cordylus giganteus, is endemic to South Africa. It has been suggested that in this species, as in other lizard species, epidermal glands in the femoral, pre-cloacal regions, and cloacal ... -
Lizard epidermal gland secretions II : chemical characterization of the generation gland secretion of the sungazer, Cordylus giganteus
(American Chemical Society and American Society of Pharmacognosy, 2011-06)In lizards, the epidermal glands of the femoral and precloacal regions are involved in the production of semiochemicals. In addition to its femoral glands, the giant girdled lizard, or sungazer, Cordylus giganteus, which ... -
Macrophysiology for a changing world
(The Royal Society, 2008-07)The Millennium Ecosystem Assessment (MA) has identified climate change, habitat destruction, invasive species, overexploitation and pollution as the major drivers of biodiversity loss and sources of concern for human ... -
Mainstreaming biodiversity : conservation for the twenty-first century
(Frontiers Media, 2015-12-08)Insufficient focused attention has been paid by the conservation community to conservation of biodiversity outside of protected areas. Biodiversity mainstreaming addresses this gap in global conservation practice by ... -
Malaria patterns across altitudinal zones of Mount Elgon following intensified control and prevention programs in Uganda
(BMC (part of Springer Nature), 2020-06-17)Background: Malaria remains a major tropical vector-borne disease of immense public health concern owing to its debilitating effects in sub-Saharan Africa. Over the past 30 years, the high altitude areas in Eastern Africa ... -
Mammal taxonomy without taxonomists : a reply to Zachos and Lovari
(Associazione Teriologica Italiana, 2013)Ontological and epistemological properties of the Phylogenetic Species Concept (PSC) as applied in recent mammalian taxonomic works are redefined and defended against criticisms raised by Zachos and Lovari (2013), which ... -
Managing conflict-generating invasive species in South Africa : challenges and trade-offs
(AOSIS Publishing, 2017)Background: This paper reviewed the benefits and negative impacts of alien species that are currently listed in the Alien and Invasive Species Regulations of the National Environmental Management: Biodiversity Act (Act no ... -
Measuring size and composition of species pools : a comparison of dark diversity estimates
(Wiley Open Access, 2016)Ecological theory and biodiversity conservation have traditionally relied on the number of species recorded at a site, but it is agreed that site richness represents only a portion of the species that can inhabit particular ... -
Micro-environment of olive ridley turtle nests deposited during an aggregated nesting event
(Wiley-Blackwell, 2007-05)The hatching success of nests deposited by olive ridley turtles Lepidochelys olivacea during aggregated nesting events ('arribada') is typically low and the underlying mechanisms are not clear. In this study, temperature, ... -
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, ... -
Mind the gap – context dependency in invasive species impacts : a case study of the ascidian Ciona robusta
(Pensoft Publishers, 2017-01-04)ENGLISH ABSTRACT: In the face of increasing invasions and limited resources, appropriate management of invasive species requires prioritisation of species for management action. This process often relies on knowledge of ... -
Mind the gaps : investigating the cause of the current range disjunction in the Cape Platanna, Xenopus gilli (Anura: Pipidae)
(PeerJ, 2013)Low-lying areas of the Cape at Africa’s south-westernmost tip have undergone dramatic marine-remodelling, with regular changes in sea-level following glacial cycles. Species for which marine barriers are impenetrable ... -
Mitochondrial DNA is unsuitable to test for isolation by distance
(Nature Research, 2018-05-31)Tests for isolation by distance (IBD) are the most commonly used method of assessing spatial genetic structure. Many studies have exclusively used mitochondrial DNA (mtDNA) sequences to test for IBD, but this marker is ... -
