Comparative phylogeography between two generalist flea species reveal a complex interaction between parasite life history and host vicariance : parasite-host association matters
(BioMed Central, 2015-06)
Background: In parasitic taxa, life history traits such as microhabitat preference and host specificity can result in
differential evolutionary responses to similar abiotic events. The present study investigates the ...
Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH)
(BMC (part of Springer Nature), 2018-09-03)
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 ...
Phylogeography of the southern African vlei rat, Otomys irroratus, inferred from chromosomal and DNA sequence data
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: This study examines the phylogeography of the southern African vlei rat, Otomys
irroratus using the mtDNA cyt b gene and chromosomal data derived using G-, and C-banding,
Ag-NOR staining and fluorescence ...
The conservation of South African white sharks : population number, genetic distinctiveness and global connections
(Stellenbosch : Stellenbosch University, 2015-03)
ENGLISH SUMMARY: The white shark (Carcharodon carcharias) is IUCN red listed as vulnerable, but the lack of basic
biological information is arguably the biggest obstacle facing the conservation of the species. The
aim ...
Phylogeographic variation of the Karoo bush rat, Otomys unisulcatus : a molecular and morphological perspective
(Stellenbosch : University of Stellenbosch, 2009-03)
Phylogeographic genetic structure has been documented for a number of southern African terrestrial taxa.
Information regarding geographic population genetic structuring in multiple taxa, with differing life
histories, ...
Inter-island dispersal of flightless Bothrometopus huntleyi (Coleoptera: Curculionidae) from the sub-Antarctic Prince Edward Island archipelago
(Cambridge University Press, 2011)
Bothrometopus huntleyi is a flightless weevil endemic to the volcanically-formed sub-Antarctic Prince Edward Islands archipelago that arose approximately 0.5 million years ago (m.y.a.). Since emergence, a series of volcanic ...
Phylogeographic patterning of three co-distributed forest-dwelling reptile species along the east coast of South Africa
(Stellenbosch : Stellenbosch University, 2019-12)
ENGLISH ABSTRACT: This study investigates the phylogeographic structure of three co-distributed forest-living reptile species, the Pondo flat gecko (Afroedura pondolia), the forest thread snake (Leptotyphlops sylvicolus) ...
Multi-model seascape genomics identifies distinct environmental drivers of selection among sympatric marine species
(BMC (part of Springer Nature), 2020-09-16)
Background: As global change and anthropogenic pressures continue to increase, conservation and management
increasingly needs to consider species’ potential to adapt to novel environmental conditions. Therefore, it ...
Population genetics of the Sporothrix splendens complex from Protea L. in South Africa
(Stellenbosch : Stellenbosch University, 2017-03)
ENGLISH ABSTRACT: Ophiostomatoid fungi consist of a remarkable assemblage of species that are distantly related (Orders Microascales and Ophiostomatales) and that are grouped based on convergent evolution towards arthropod ...
The phylogeographic population structure of the Cape sea urchin, Parechinus angulosus
(Stellenbosch : Stellenbosch University, 2011-03)
ENGLISH ABSTRACT: South Africa's coastline is in the region of 3650kms and encompasses many different and dynamic marine environments. To enhance our current understanding of the population structure and gene flow patterns ...
