Construction of bacterial artificial chromosome libraries for the Lake Malawi cichlid (Metriaclima zebra), and the blind cavefish (Astyanax mexicanus).
Teleost fishes have become important models for studying the evolution of the genetic mechanisms of development. A key resource for comparative genomics and positional cloning are large-insert libraries constructed in bacterial artificial chromosomes. We have constructed bacterial artificial chromosome libraries for two species of teleost fish that are important models for the study of developm...
متن کاملEvolution of genomic structural variation and genomic architecture in the adaptive radiations of African cichlid fishes
African cichlid fishes are an ideal system for studying explosive rates of speciation and the origin of diversity in adaptive radiation. Within the last few million years, more than 2000 species have evolved in the Great Lakes of East Africa, the largest adaptive radiation in vertebrates. These young species show spectacular diversity in their coloration, morphology and behavior. However, littl...
متن کاملVisual pigments of African cichlid fishes: evidence for ultraviolet vision from microspectrophotometry and DNA sequences
We have found evidence for ultraviolet visual capabilities in a Lake Malawi cichlid fish, Metriaclima zebra. Microspectrophotometry of single cones revealed a visual pigment with peak sensitivity at 368+/-4 nm. M. zebra also expresses a putative ultraviolet opsin gene whose sequence is closely related to the SWS-1 opsin for other fishes. Several other African cichlids have a functional copy of ...
متن کاملVariation in body size and trophic morphology within and among genetically differentiated populations of the cichlid fish, Metriaclima zebra, from Lake Malawi
1. The cichlid fish Metriaclima zebra, common in Lake Malawi, feeds by filtering plankton from the water and by brushing items from sediment covered substrata. It inhabits isolated rocky reefs among which community structure, resource availability and gene pools are likely to differ. We speculated that body size and trophic morphology of M. zebra might vary concomitantly. 2. We quantified the e...
متن کاملThe Well-known Red Zebra Cichlid from Lake Malawi
206 Introduetion T he small rock-dwelling cichlids of Lake Malawi are colleetively known as mbuna and, until recently, were neglected by African fishermen. Currently the mbuna are classified among ten different genera in which more than 70 species have been scientifically described. More than double that number of mbuna species are still without a scientific name, most of them to be grouped in ...
