This study used phylogenetic analyses of mitochondrial cytochrome b sequences to investigate genetic diversity within three broadly co-distributed freshwater fish genera (Galaxias, Pseudobarbus and Sandelia) to shed some light on the processes that promoted lineage diversification and shaped geographical distribution patterns. A total of 205 sequences of(More)
A new species of freshwater crab, Potamonautesisimangaliso sp. n., is described from the western shores of False Bay, Hluhluwe, within the iSimangaliso Wetland Park, South Africa. While bearing a superficial resemblance to Potamonauteslividus, the new species has been found to be genetically distinct, diverging from the former by 7.4-7.8% in mtDNA.(More)
A new species of freshwater crab, Potamonautes danielsisp. n., is described from the southern region of the KwaZulu-Natal Province, South Africa. Potamonautes danielsi most closely resembles Potamonautes sidneyi which is re-described here, but can be distinguished by a suite of key morphological characters including carapace shape and width, slim pereopods,(More)
Ecological epigenetics is gaining importance within the field of Molecular Ecology, because of its novel evolutionary implications. Linking population ecology to the variation in epigenetic profiles can help explain the effect of environmental conditions on phenotypic differences among populations. While epigenetic changes have largely been investigated(More)
Marine geographical and ecological barriers often reflect intraspecific genetic discontinuities among populations which may experience different selective pressures and undergo evolutionary divergence. While the phylogeography of marine intertidal invertebrates across the Atlantic/Indian Ocean transition received more attention, the population genetic(More)
