Functional Diversification within a Predatory Species Flock
Ecological speciation is well-known from adaptive radiations in cichlid fishes inhabiting lentic ecosystems throughout the African rift valley and Central America. Here, we investigate the ecological and morphological diversification of a recently discovered lotic predatory Neotropical cichlid species flock in subtropical South America. We document morphological and functional diversification u...
متن کاملEvolution of Functional Diversification within Quasispecies
According to quasispecies theory, high mutation rates limit the amount of information genomes can store (Eigen's Paradox), whereas genomes with higher degrees of neutrality may be selected even at the expenses of higher replication rates (the "survival of the flattest" effect). Introducing a complex genotype to phenotype map, such as RNA folding, epitomizes such effect because of the existence ...
متن کاملA Species Flock Driven by Predation? Secondary Metabolites Support Diversification of Slugs in Antarctica
Antarctica's rich marine animal biodiversity has been substantially influenced by a complex glacial history, but it is unclear why some taxa responded with diversification while others did not. Despite being considered a single endemic sea slug species in the Southern Ocean, mitochondrial DNA sequencing of Doris kerguelenensis (Bergh, 1884) revealed a multitude of highly divergent lineages. But...
متن کاملGenetic mosaic in a marine species flock.
We used molecular approaches to study the status of speciation in coral reef fishes known as hamlets (Serranidae: Hypoplectrus). Several hamlet morphospecies coexist on Caribbean reefs, and mate assortatively with respect to their strikingly distinct colour patterns. We provide evidence that, genetically, the hamlets display characteristics common in species flocks on land and in freshwaters. S...
متن کاملDeciphering functional diversification within the lichen microbiota by meta-omics
BACKGROUND Recent evidence of specific bacterial communities extended the traditional concept of fungal-algal lichen symbioses by a further organismal kingdom. Although functional roles were already assigned to dominant members of the highly diversified microbiota, a substantial fraction of the ubiquitous colonizers remained unexplored. We employed a multi-omics approach to further characterize...
