The Gut Microbial Community of Midas Cichlid Fish in Repeatedly Evolved Limnetic-Benthic Species Pairs
Gut bacterial communities are now known to influence a range of fitness related aspects of organisms. But how different the microbial community is in closely related species, and if these differences can be interpreted as adaptive is still unclear. In this study we compared microbial communities in two sets of closely related sympatric crater lake cichlid fish species pairs that show similar ad...
متن کاملGenomic architecture of ecologically divergent body shape in a pair of sympatric crater lake cichlid fishes.
Determining the genetic bases of adaptations and their roles in speciation is a prominent issue 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, divergence in ecomorphological traits - including...
متن کاملEcological and Evolutionary Consequences of Color- and Trophic Polymorphisms in Cichlid Fishes
12 benthic-limnetic axis and most populations are also color-polymorphic. The most comprehensive project focuses on the gold/dark color polymorphism in the Midas cichlid species complex (Amphilophus citrinellus spp.). Using a comparative approach that bases on extensive field collections of Midas cichlids, a substantial degree of ecological differentiation between color morphs is revealed. The ...
متن کاملConvergent Evolution within an Adaptive Radiation of Cichlid Fishes
The recurrent evolution of convergent forms is a widespread phenomenon in adaptive radiations (e.g., [1-9]). For example, similar ecotypes of anoles lizards have evolved on different islands of the Caribbean, benthic-limnetic species pairs of stickleback fish emerged repeatedly in postglacial lakes, equivalent sets of spider ecomorphs have arisen on Hawaiian islands, and a whole set of converge...
متن کاملLake Malawi cichlid evolution along a benthic/limnetic axis
Divergence along a benthic to limnetic habitat axis is ubiquitous in aquatic systems. However, this type of habitat divergence has largely been examined in low diversity, high latitude lake systems. In this study, we examined the importance of benthic and limnetic divergence within the incredibly species-rich radiation of Lake Malawi cichlid fishes. Using novel phylogenetic reconstructions, we ...
