Owing to their taxonomic, phenotypic, ecological and behavioural diversity and propensity
for explosive diversification, the assemblages of cichlid fish in the East African Great Lakes …

Sedimentary sequences in ancient or long-lived lakes can reach several thousands of
meters in thickness and often provide an unrivalled perspective of the lake's regional …

Long paleoecological records are critical for understanding evolutionary responses to
environmental forcing and unparalleled tools for elucidating the mechanisms that lead to the …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

The gut microbiota structure reflects both a host phylogenetic history and a signature of
adaptation to the host ecological, mainly trophic niches. African cichlid fishes, with their array …

Ecoevolutionary dynamics of the gut microbiota at the macroscale level, that is, in across-
species comparisons, are largely driven by ecological variables and host genotype. The …

In this Special feature, we assemble studies that illustrate phylogenetic approaches to
studying salient questions regarding the effect of specialization on lineage diversification …

According to theory, adaptive radiation is triggered by ecological opportunity that can arise
through the colonization of new habitats, the extinction of antagonists or the origin of key …

Divergent natural selection acting in different habitats may build up barriers to gene flow and
initiate speciation. This speciation continuum can range from weak or no divergence to …

Innovations can facilitate bursts of diversification by increasing access to novel resources
and the attainment of novel functional designs. Pharyngognathy, exhibited by highly diverse …
