Article
Full-text available
The genus Eigenmannia comprises several species groups that display a surprising variety of diploid chromosome numbers and sex-determining systems. In this study, hypotheses regarding phylogenetic relationships and karyotype evolution were investigated using a combination of molecular and cytogenetic methods. Phylogenetic relationships were analyze...
Article
Full-text available
With more than 1,500 species, cichlid fishes provide textbook examples of recent and diverse adaptive radiations, rapid rates of speciation, and the parallel evolution of adaptive phenotypes among both recently and distantly related lineages. This extraordinary diversity has attracted considerable interest from researchers across several biological...
Article
Full-text available
Genes of major phenotypic effects and strong genetic correlations can facilitate adaptation, direct selective responses and potentially lead to phenotypic convergence. However, the preponderance of this type of genetic architecture in repeatedly-evolved adaptations is unknown. Using hybrids between Haplochromis chilotes and H. nyererei we investiga...
Article
Full-text available
The evolution of sex chromosomes and their differentiation from autosomes is a major event during genome evolution that happened many times in several lineages. The repeated evolution and lability of sex‐determination mechanisms in fishes makes this a well‐suited system to test for general patterns in evolution. According to current theory, differe...
Article
Full-text available
Polymorphisms have fascinated biologists for a long time, but their genetic underpinnings often remain elusive. Here, we aim to uncover the genetic basis of the gold/dark polymorphism that is eponymous of Midas cichlid fish (Amphilophus spp.) adaptive radiations in Nicaraguan crater lakes. While most Midas cichlids are of the melanic “dark morph”,...
Article
Over the last few years, molecular species identification has revealed high levels of seafood mislabelling, which has generated public concern. The success of regulatory efforts depends on the accurate estimation of species substitution across multiple points in the supply chain. Flounders are among the most popular and highly valued seafood produc...
Article
Fishing has a major impact on the biodiversity of elasmobranchs, a diverse and ancient group of fish. The illegal trade of products derived from endangered species is widespread and many times concealed by both deliberate and inadvertent mislabeling. In groups where data is sparse, such as guitarfishes, it is unknown which species are at a higher r...
Article
Full-text available
The transition from ‘well-marked varieties’ of a single species into ‘well-defined species’—especially in the absence of geographic barriers to gene flow (sympatric speciation)—has puzzled evolutionary biologists ever since Darwin1,2. Gene flow counteracts the buildup of genome-wide differentiation, which is a hallmark of speciation and increases t...
Article
The color patterns of African cichlid fishes provide notable examples of phenotypic convergence. Across the more than 1200 East African rift lake species, melanic horizontal stripes have evolved numerous times. We discovered that regulatory changes of the gene agouti-related peptide 2 (agrp2) act as molecular switches controlling this evolutionaril...
Article
Full-text available
Lake Tanganyika is the oldest and phenotypically most diverse of the three East African cichlid fish adaptive radiations. It is also the cradle for the younger parallel haplochromine cichlid radiations in Lakes Malawi and Victoria. Despite its evolutionary significance, the relationships among the main Lake Tanganyika lineages remained unresolved,...
Article
Full-text available
Stress during pregnancy may impact subsequent generations, which is demonstrated by an increased susceptibility to childhood and adulthood health problems in the children and grandchildren. Although the importance of the prenatal environment is well reported with regards to future physical and emotional outcomes, little is known about the molecular...
Article
Full-text available
The independent evolution of the two toothed jaws of cichlid fishes is thought to have promoted their unparalleled ecological divergence and species richness. However, dental divergence in cichlids could exhibit substantial genetic covariance and this could dictate how traits like tooth numbers evolve in different African Lakes and on their two jaw...
Article
Full-text available
Midas cichlid fish are a Central American species flock containing 13 described species that has been dated to only few thousand years old, a historical timescale infrequently associated with speciation. Their radiation involved the colonization of several clear water crater lakes from two turbid great lakes. Therefore, Midas cichlids have been sub...
Article
Full-text available
Sympatric speciation has been debated in evolutionary biology for decades. Although it has gained in acceptance recently, still only a handful of empirical examples are seen as valid (e.g. crater lake cichlids). In this study, we disentangle the role of hypertrophied lips in the repeated adaptive radiations of Nicaraguan crater lake cichlid fish. W...
Article
Full-text available
Our understanding of how biological diversity arises is limited, especially in the case of speciation in the face of gene flow. Here we investigate the genomic basis of adaptive traits, focusing on a sympatrically diverging species pair of crater lake cichlid fishes. We identify the main quantitative trait loci (QTL) for two eco-morphological trait...
Data
Supplementary Figures 1-4, Supplementary Table 1
Data
Sequencing statistics of the individuals used in the QTL analysis. For each parent, F1 and F2 individual, the number of retained reads after quality filtering and the RAD library in which it was included are shown. When multiple markers blasted on the same genomic scaffold, only one has been retained.
Data
Significance of Fisher exact test. The values, computed on genomic windows of 500 bp within the genomic scaffolds containing RAD markers in the map, are provided both as raw p-values and as values corrected with the SGoF Binomial procedure. When multiple markers blasted on the same genomic scaffold, only one has been retained.
Data
Genes under selection. Annotation, position in the Midas draft genome and localization in the QTL Bayesian credibility intervals for each gene with dN/dS higher than 1 in all four procedures used (see Methods for details) are shown.
Data
FST values. The values refer to genomic windows of 500 bp within the genomic scaffolds containing RAD markers in the map and, therefore, unequivocally attributable to linkage groups and QTL regions.
Article
The visual system in the colorful cichlid fishes from the African great lakes is believed to be important for their adaptive radiations. However, few studies have attempted to compare the visual system of radiating cichlid lineages to that of cichlids that have not undergone recent radiations. One such study published in this journal (Schott et al....
Article
Full-text available
Linking phenotypic traits to an adaptive ecological function is a major goal of evolutionary biology. However, this task is challenging and has been accomplished in only a handful of species and ecological model systems. The repeatedly evolved adaptive radiations of cichlid fishes are composed of an enormously diverse set of species that differ in...
Article
Full-text available
The genetic dissection of naturally occurring phenotypes sheds light on many fundamental and longstanding questions in speciation and adaptation and is a central research topic in evolutionary biology. Until recently, forward-genetic approaches were virtually impossible to apply to non-model organisms, but the development of next-generation sequenc...
Article
Full-text available
The spectacular species richness of cichlids and their diversity in morphology, coloration, and behaviour have made them an ideal model for the study of speciation and adaptive evolution. Hypertrophic lips evolved repeatedly and independently in African and Neotropical cichlid radiations. Cichlids with hypertrophic lips forage predominantly in rock...
Article
Full-text available
Determining the genetic bases of adaptations and their roles in speciation are prominent issues in evolutionary biology. Cichlid fish species flocks are a prime example of recent rapid radiations often associated with adaptive phenotypic divergence from a common ancestor within a short period of time. In several radiations of freshwater fishes dive...
Article
Full-text available
Background Animal pigmentation has received much attention in evolutionary biology research due to its strong implications for adaptation and speciation. However, apart from a few cases the genetic changes associated with these evolutionary processes remain largely unknown. The Midas cichlid fish from Central America are an ideal model system for i...
Article
Full-text available
Sexual selection on male coloration is one of the main mechanisms proposed to explain the explosive speciation rates in East African cichlid fish. True eggspots are color patterns characteristic of the most species-rich lineage of cichlids, the Haplochromini, and have been suggested to be causally related to the speciation processes. Eggspots are t...

Natural populations of the Midas cichlid species in several different crater lakes in Nicaragua exhibit a conspicuous color polymorphism. Most individuals are dark and the remaining have a gold coloration. The color morphs mate assortatively and sympatric population differentiation has been shown based on neutral molecular data. We investigated the...

Full-text available
Cichlid fishes compose an astonishingly large number of species and formed species flocks in record-breaking time. To facilitate efficient genome scans and comparisons of cichlid genomes, we constructed a medium-density genetic linkage map of microsatellite markers of Astatotilapia burtoni. The mapping cross was derived from two inbred laboratory l...
Article
Full-text available
Chromosome microdissection is a technique in which whole chromosomes or chromosomal segments are dissected under an inverted microscope yielding chromosome-specific sequences. Several protocol modifications introduced during the past 15 years reduced the number of chromosomes required for most applications. This is of particular interest to fish mo...

Full-text available
The Neotropical genus Eigenmannia is a fish group with unknown species diversity where representatives possess a broad range of chromosomal sex determining systems namely XY/XX, X(1)X(2)Y/X(1)X(1)X(2)X(2), ZZ/ZW as well as homomorphic sex chromosomes. To test the homology of two heteromorphic XY sex chromosome systems present in two sympatric popul...
