Open AccessCumulative SARS-CoV-2 mutations and corresponding changes in immunity in an immunocompromised patient indicate viral evolution within the host
Different scenarios explaining the emergence of novel variants of concern (VOC) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported, including their evolution in scarcely mon...

Article
Open AccessExpression variations in ectodysplasin-A gene (eda) may contribute to morphological divergence of scales in haplochromine cichlids
Elasmoid scales are one of the most common dermal appendages and can be found in almost all species of bony fish differing greatly in their shape. Whilst the genetic underpinnings behind elasmoid scale develop...

Open AccessMicroevolutionary change in viscerocranial bones under congeneric sympatry in the Lake Tanganyikan cichlid genus Tropheus
The endemic Lake Tanganyika cichlid genus Tropheus lives at rocky shores all around the lake and comprises six species which are subdivided into about 120 morphologically similar but color-wise distinct populatio...

Open AccessTranscriptomics unravels molecular players sha** dorsal lip hypertrophy in the vacuum cleaner cichlid, Gnathochromis permaxillaris
Teleosts display a spectacular diversity of craniofacial adaptations that often mediates ecological specializations. A considerable amount of research has revealed molecular players underlying skeletal craniof...

Open AccessGene coexpression networks reveal molecular interactions underlying cichlid jaw modularity
The oral and pharyngeal jaw of cichlid fishes are a classic example of evolutionary modularity as their functional decoupling boosted trophic diversification and contributed to the success of cichlid adaptive ...

Open AccessCorrection to: An in vitro model for assessment of SARS‑CoV‑2 infectivity by defining the correlation between virus isolation and quantitative PCR value: isolation success of SARS‑CoV‑2 from oropharyngeal swabs correlates negatively with Cq value
An amendment to this paper has been published and can be accessed via the original article.

Open AccessAn in vitro model for assessment of SARS-CoV-2 infectivity by defining the correlation between virus isolation and quantitative PCR value: isolation success of SARS-CoV-2 from oropharyngeal swabs correlates negatively with Cq value
At the beginning of the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), little was known about its actual rate of infectivity and any COVID-19 patient positive in laboratory te...

Open AccessDiscriminating larvae of two syntopic Cychramus species (Coleoptera, Nitidulidae) by means of bar-HRM analysis
Molecular genetic methods are increasingly used to supplement or substitute classical morphology-based species identification. Here, we employ a COI mini-barcode coupled high-resolution melting analysis to qui...

Article
Open AccessMolecular mechanisms underlying nuchal hump formation in dolphin cichlid, Cyrtocara moorii
East African cichlid fishes represent a model to tackle adaptive changes and their connection to rapid speciation and ecological distinction. In comparison to bony craniofacial tissues, adaptive morphogenesis ...

Article
Open AccessDivergence in larval jaw gene expression reflects differential trophic adaptation in haplochromine cichlids prior to foraging
Understanding how variation in gene expression contributes to morphological diversity is a major goal in evolutionary biology. Cichlid fishes from the East African Great lakes exhibit striking diversity in tro...

Article
Open AccessOnly true pelagics mix: comparative phylogeography of deepwater bathybatine cichlids from Lake Tanganyika
In the absence of dispersal barriers, species with great dispersal ability are expected to show little, if at all, phylogeographic structure. The East African Great Lakes and their diverse fish faunas provide ...

Article
Open AccessMaternal mRNA input of growth and stress-response-related genes in cichlids in relation to egg size and trophic specialization
Egg size represents an important form of maternal effect determined by a complex interplay of long-term adaptation and short-term plasticity balancing egg size with brood size. Haplochromine cichlids are mater...

Article
Open AccessPhylogenomics uncovers early hybridization and adaptive loci sha** the radiation of Lake Tanganyika cichlid fishes
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 Lake...

Open AccessPhylogeny and phylogeography of Altolamprologus: ancient introgression and recent divergence in a rock-dwelling Lake Tanganyika cichlid genus
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 d...

Open AccessA separate lowstand lake at the northern edge of Lake Tanganyika? Evidence from phylogeographic patterns in the cichlid genus Tropheus
In Lake Tanganyika, lake level fluctuations were shown to have had a major impact on the evolution of littoral species. Many species are subdivided into arrays of populations, geographical races and sister spe...

Open AccessHidden biodiversity in an ancient lake: phylogenetic congruence between Lake Tanganyika tropheine cichlids and their monogenean flatworm parasites
The stunning diversity of cichlid fishes has greatly enhanced our understanding of speciation and radiation. Little is known about the evolution of cichlid parasites. Parasites are abundant components of biodi...

Open AccessBig fish, little divergence: phylogeography of Lake Tanganyika’s giant cichlid, Boulengerochromis microlepis
The largely endemic cichlid species flocks of the East African Great Lakes are among the prime examples for explosive speciation and adaptive radiation. Speciation rates differ among cichlid lineages, and the ...

Open AccessPopulation dynamics with a mixed type of sexual and asexual reproduction in a fluctuating environment
Carassius gibelio, a cyprinid fish from Eurasia, has the ability to reproduce both sexually and asexually. This fish is also known as an invasive species which colonized almost all continental Europe, most likely...

Open AccessGenetic and morphological population differentiation in the rock-dwelling and specialized shrimp-feeding cichlid fish species Altolamprologus compressiceps from Lake Tanganyika, East Africa
With about 250 endemic species, Lake Tanganyika contains an extraordinarily diverse cichlid fish fauna, and thus represents an ideal model system for the study of pathways and processes of speciation. The Lamp...
