Research

Interests

I am highly interested in speciation, its processes and patterns, phylogenetics, population genetics, biogeography and palaeontology. Current research interests focus on the testing of ecological speciation in a Lake Tanganyika cichlid using molecular and ecological approaches.

 

Project name

Testing ecological speciation in Lake Tanganyika cichlids

Project description 

Department of Zoology: Kai Winkelmann
Supervisors: Dr Martin Genner (Bristol), Dr Lukas Rüber (NHM, London)

The African Great Lakes contain spectacular adaptive radiations of cichlid fishes. This project focuses on Telmatochromis temporalis (Cichlidae, Lamprologini), a Lake Tanganyika endemic. T. temporalis is a highly sedentary substrate breeder that is broadly distributed in littoral habitats throughout the lake. A notably characteristic of this species is the occurrence of two morphs that differ strikingly in body size. The large morph reaches sexual maturity between 60 and 85 mm SL (standard length) whereas the dwarf morph matures at between 38 and 44 mm SL. Importantly the different morphs show an obvious difference in substrate preference in the wild. While the large morph is found on rocky habitat, the dwarf morph is restricted to shell beds. Previous work using data from morphometrics, microsatellite DNA and mitochondrial DNA has indicated that the two morphs have evolved multiple times. This strongly suggests divergence has been driven by substrate preferences. However, before we can conclude that true parallel ecological speciation has taken place we still require evidence from more extensive geographic sampling, a reliable phylogeny built from nuclear loci, experimental evidence of substrate preferences, and experimental evidence of mate choice preferences.
