“…Sequences were aligned by eye (protein coding sequences) or using MUSCLE (Edgar, 2004) (for non-coding sequences and rDNA) as implemented in Mega 6.05 (Tamura et al, 2013). Our newly generated sequence data were complemented with previously published sequences of 'ossified group' lamprologines and outgroup taxa Schelly et al, 2006;Koblmüller et al, 2007b;Nevado et al, 2009), downloaded from Genbank (Supplementary Table 2). New sequences are deposited in GenBank (for GenBank accession numbers, see Supplementary Tables 1 and 2).…”

“…Mitochondrial replacement in isolated populations and even in entire species is being inferred in an increasing number of taxa (e.g. Nevado et al, 2011;Tang et al, 2012;Melo-Ferreira et al, 2014;Good et al, 2015), including lamprologines (Schelly et al, 2006;Nevado et al, 2009). Lamprologine species can produce interspecific offspring for long periods of time following their divergence (Koblmüller et al, 2007b;Sturmbauer et al, 2010), which may explain the frequency of interspecific introgressions detected in this group.…”

Stenotopic specialization to a fragmented habitat promotes the evolution of genetic structure. It is not yet clear whether small-scale population structure generally translates into large-scale intraspecific divergence. In the present survey of mitochondrial genetic structure in the Lake Tanganyika endemic Altolamprologus (Teleostei, Cichlidae), a rock-dwelling cichlid genus comprising A. compressiceps and A. calvus, habitat-induced population fragmentation contrasts with weak phylogeographic structure and recent divergence among genetic clades. Low rates of dispersal, perhaps along gastropod shell beds that connect patches of rocky habitat, and periodic secondary contact during lake level fluctuations are apparently sufficient to maintain genetic connectivity within each of the two Altolamprologus species. The picture of genetic cohesion was interrupted by a single highly divergent haplotype clade in A. compressiceps restricted to the northern part of the lake. Comparisons between mitochondrial and nuclear phylogenetic reconstructions suggested that the divergent mitochondrial clade originated from ancient interspecific introgression. Finally, 'isolation-with-migration' models indicated that divergence between the two Altolamprologus species was recent (67-142 KYA) and proceeded with little if any gene flow. As in other rock-dwelling cichlids, recent population expansions were inferred in both Altolamprologus species, which may be connected with drastic lake level fluctuations.

“…These views changed in the last two decades with the advent of molecular genetic methods for tracking gene flow between species (Grant & Grant 1992;Arnold 1997;Barton 2001;Seehausen 2004). Hybridization between animal species is widespread, both in early stages of speciation (Grant et al 2004) and between non-sister species (Salzburger et al 2002;Schelly et al 2006). Depending on circumstances, interspecific hybridization may have very different consequences.…”

Theory suggests that genetic polymorphisms in female mating preferences may cause disruptive selection on male traits, facilitating phenotypic differentiation despite gene flow, as in reinforcement or other models of speciation with gene flow. Very little experimental data have been published to test the assumptions regarding the genetics of mate choice that such theory relies on. We generated a population segregating for female mating preferences and male colour dissociated from other species differences by breeding hybrids between species of the cichlid fish genus Pundamilia. We measured male mating success as a function of male colour. First, we demonstrate that non-hybrid females of both species use male nuptial coloration for choosing mates, but with inversed preferences. Second, we show that variation in female mating preferences in an F 2 hybrid population generates a quadratic fitness function for male coloration suggestive of disruptive selection: intermediate males obtained fewer matings than males at either extreme of the colour range. If the genetics of female mate choice in Pundamilia are representative for those in other species of Lake Victoria cichlid fish, it may help explain the origin and maintenance of phenotypic diversity despite some gene flow.

Genetic population structure as indirect measure of dispersal ability in a Lake Tanganyika cichlid

Diversification and speciation processes are influenced by intrinsic (ecological specialization, dispersal) and extrinsic (habitat structure and instability) factors, but the effect of ecological characteristics on dispersal is difficult to assess. This study uses mitochondrial control region sequences to investigate the population structure and demographic history of the endemic Lake Tanganyika cichlid Neolamprologus caudopunctatus with a preference for the rock-sand interface along two stretches of continuous, rocky shoreline, and across a sandy bay representing a potential dispersal barrier. Populations along uninterrupted habitat were not differentiated; whereas, the sandy bay separated two reciprocally monophyletic clades. The split between the two clades between 170,000 and 260,000 years BP coincides with a period of rising water level following a major lowstand, and indicates that clades remained isolated throughout subsequent lake level fluctuations. Low long-term effective population sizes were inferred from modest genetic diversity estimates, and may be due to recent population expansions starting from small population sizes 45,000-60,000 years BP. Comparisons with available data from specialized rock-dwelling species of the same area suggest that habitat structure and lake level fluctuations determine phylogeographic patterns on large scales, while fine-scale population structure and demography are modulated by species-specific ecologies.
