Genetic variation and population structure in remnant populations of black rhinoceros, Diceros bicornis, in Africa
Black rhinoceros (Diceros bicornis) are one of the most endangered mammal species in Africa, with a population decline of more than 96% by the end of the last century. Habitat destruction and…

Microsatellite analysis of genetic diversity in fragmented South African buffalo populations
TLDR
The genetic estimates of census size were consistent with historical records, and no historical genetic differentiation could be inferred in the original population before fragmentation, and differentiation was detected among all populations measured by FST and RST.

Cryptic Diversity of African Tigerfish (Genus Hydrocynus) Reveals Palaeogeographic Signatures of Linked Neogene Geotectonic Events
TLDR
Phylogeographic tests reveal that the diversity and distribution of Hydrocynus reflects a complex history of vicariance and dispersals, whereby range expansions in particular species testify to changes to drainage basins.

Phylogenetic analysis of toxic Alexandrium (Dinophyceae) isolates from South Africa: implications for the global phylogeography of the Alexandrium tamarense species complex
TLDR
The geographic distribution of Alexandrium populations in South African waters is discussed in relation to regional biogeographic patterns and it is suggested that the A. tamiyavanichi population is derived from West Pacific ancestral stocks via a West Pacific–East–South African dispersal route.

Single-cell sequencing of dinoflagellate (Dinophyceae) nuclear ribosomal genes
TLDR
This method, based on freeze–thaw cell lysis and a simple two-step polymerase chain reaction, provides template for sequencing in 6–8 h and sequenced five dinoflagellate species, including unculturable Dinophysis and Ceratium species, using fresh and frozen samples.

Investigation of genetic diversity in fragmented geometric tortoise (Psammobates geometricus) populations
Microsatellite DNA was used to investigatelevels of genetic variability in severelyfragmented populations of the geometrictortoise, Psammobates geometricus, themost endangered tortoise on mainland…

Molecular insight into patterns of colony composition and paternity in the common mole‐rat Cryptomys hottentotus hottentotus
TLDR
Results from genetic assignment tests using microsatellite markers indicate that while colony composition is dominated by familial groups, colonies within both populations included both adult and subadult foreign conspecifics, and analysis of parentage reveals that the social organization of C. h.

Monogamous dominant pairs monopolize reproduction in the cooperatively breeding pied babbler
TLDR
Genetic data are used from a population of cooperatively breeding pied babblers to show that reproduction is highly skewed toward behaviorally dominant birds, and helping in this species confers indirect fitness benefits on subordinates, which are likely to play an important role in the evolution and maintenance of cooperative helping behavior.

Microsatellite analysis reveals that domestic cat (Felis catus) and southern African wild cat (F. lybica) are genetically distinct
TLDR
The data indicate that the level of genetic introgression is lower than previously thought, which enhances the conservation status of the African wild cat and demonstrates the need for the implementation of feral cat control in and around game reserves and rural areas.
