Developmental divergence in gene regulation among rapidly radiating cichlid species

This study examines gene regulation changes during development in cichlid fishes, finding species-specific expression patterns linked to trophic niche adaptation.

Testing for a role of postzygotic incompatibilities in rapidly speciated Lake Victoria cichlids

The paper tests the role of postzygotic incompatibilities in Lake Victoria cichlids, finding little evidence for their major role but suggesting some loci may have been sorted during early speciation events.

Microtomographic investigation of a large corpus of cichlids

The paper describes a method for nondestructively imaging cichlids using micro-CT and presents morphological analyses of their jaws and skulls.

Hybridization and a mixture of small and large-effect loci facilitate adaptive radiation

The paper investigates the role of genetic architecture and hybridization in adaptive radiation using Alpine whitefish data, finding both genome-wide shifts and a large-effect locus contribute to diversification.

Blue and green food webs respond differently to elevation and land use

The paper compares structural and ecological differences between blue and green food webs across elevation and land use in Switzerland, finding divergent responses to environmental gradients.

The interaction of climate history and evolution impacts alpine biodiversity assembly differently in freshwater and on land

The paper examines how climate history and evolution shaped alpine biodiversity differently in freshwater and terrestrial ecosystems, finding distinct patterns of speciation linked to glacial refugia and adaptive radiation.

Isotopic signatures induced by upwelling reveal regional fish populations in Lake Tanganyika

The paper uses isotopic analysis of fish from Lake Tanganyika to show regional population differences driven by hydrodynamics, but not diet or lipid content.

The genetic population structure of Lake Tanganyika's Lates species flock, an endemic radiation of pelagic top predators

The paper investigates genetic connectivity in four Lake Tanganyika Lates species using genomic sequencing, finding strong differentiation between species and weak structure within some species.

Four new species of Cichlidogyrus (Platyhelminthes, Monogenea, Dactylogyridae) from Lake Victoria haplochromine cichlid fishes, with the redescription of C. bifurcatus and C. longipenis

The paper describes four new species of Cichlidogyrus parasites from Lake Victoria cichlids and redescribes two existing species, highlighting morphological features and evolutionary patterns.

Structural genomic variation leads to unexpected genetic differentiation in Lake Tanganyika's sardines

The paper identifies sex-specific genomic regions and a segregating inversion in two Lake Tanganyika sardine species, revealing rapid XY sex determination evolution and population structure not explained by geography.

Movement of transposable elements contributes to cichlid diversity

The paper identifies transposable element (TE)-induced indels as causative variants for visual sensitivity shifts in Lake Malawi cichlids, linking TE mobility to phenotypic diversity.

Polygenic selection drives the evolution of convergent transcriptomic landscapes across continents within a Nearctic sister-species complex.

The paper investigates convergent transcriptomic landscapes in limnetic and benthic whitefish species pairs across continents, finding shared genomic bases for differential gene expression under polygenic selection.

Visual adaptation and microhabitat choice in Lake Victoria cichlid fish

This study examines visual habitat preferences in Lake Victoria cichlid fish, finding a preference for broad-spectrum light over their typical habitat, suggesting visual adaptation does not directly drive microhabitat choice.

A dense linkage map of Lake Victoria cichlids improved the Pundamilia genome assembly and revealed a major QTL for sex-determination

The paper constructs a high-resolution genetic linkage map for Lake Victoria cichlids, improves the genome assembly, and identifies a major QTL for sex determination.
