The cushion–star Parvulastra exigua in South Africa : one species or more?
(Pensoft, 2015-09)
The cushion–star Parvulastra exigua (Lamarck, 1816) is a widely distributed member of the temperate
intertidal fauna in the southern hemisphere. In South Africa, it occurs in sympatry with the endemic
Parvulastra dyscrita ...
When homoplasy mimics hybridization : a case study of Cape hakes (Merluccius capensis and M. paradoxus)
(PeerJ, 2016)
In the marine environment, an increasing number of studies have documented introgression and hybridization using genetic markers. Hybridization appears to occur preferentially between sister-species, with the probability ...
Evidence for panmixia despite barriers to gene flow in the southern African endemic, Caffrogobius caffer (Teleostei: Gobiidae)
(BioMed Central, 2008-12)
Background: Oceanography and life-history characteristics are known to influence the genetic structure of marine species, however the relative role that these factors play in shaping phylogeographic patterns remains ...
A review of marine phylogeography in southern Africa
(Academy of Science of South Africa, 2011)
The southern African marine realm is located at the transition zone between the Atlantic
and Indo-Pacific biomes. Its biodiversity is particularly rich and comprises faunal and floral
elements from the two major oceanic ...
The ghost of introduction past : spatial and temporal variability in the genetic diversity of invasive smallmouth bass
(Wiley Open Access, 2018)
Understanding the demographic history of introduced populations is essential for
unravelling their invasive potential and adaptability to a novel environment. To this
end, levels of genetic diversity within the native ...
Fine-scale biogeography : tidal elevation strongly affects population genetic structure and demographic history in intertidal fishes
(University of California, eScholarship, 2013)
Numerous studies have demonstrated population genetic structuring in marine species, yet
few have investigated the effect of vertical zonation on gene flow and population structure. Here we use
three sympatric, closely ...
Science to policy – reflections on the South African reality
(Academy of Science of South Africa, 2016)
Research is a key resource in a knowledge economy and governance system. In order to enable
research to
benefit the nation and to contribute to growing the knowledge-based economy (the aims of the Global
Change Grand ...
Genetic and biophysical models help define marine conservation focus areas
(Frontiers Media, 2018-08-06)
Ecological and environmental variables play a major role in the genetic structure of marine populations, but how oceanography affects their dispersal and associated connectivity remains far from being understood. To account ...
Complex signatures of genomic variation of two non-model marine species in a homogeneous environment
(BioMed Central, 2018-05-09)
Background: Genomic tools are increasingly being used on non-model organisms to provide insights into population
structure and variability, including signals of selection. However, most studies are carried out in regions ...
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 ...
