Cichlid fishes of Lake Tanganyika display a variety of mating and parental care behaviors, including polygamous and monogamous mouthbrooding and substrate breeding, cooperative breeding, as well as various alternative reproductive tactics such as sneaking and piracy. Moreover, reproductive behaviors sometimes vary within species both in space and in time. Here, I survey reports on mating and pa...

This article focuses on convict labour in the Namibian–Cape border region late 19th and early 20th centuries. It situates this form of unfree within broader trans-colonial discussions...

Introduction Modes of African cichlid speciation Radiation in stages model Genetic bases of jaw and teeth morphology Signature genes for sexual selection

Female mate choice has often been proposed to play an important role in cases of rapid speciation, in particular in the explosively evolved haplochromine cichlid species flocks of the Great Lakes of East Africa. Little, if anything, is known in cichlid radiations about the heritability of female mating preferences. Entirely sympatric distribution, large ecological overlap and conspicuous differ...
