Genomic Consequences of Ecological Speciation in Astyanax Cavefish
The cave environment is consistently radically different than the surface environment because it lacks light, and animals adapting to cave life are subject to strong selective forces much different than those experienced by their ancestors who evolved in the presence of light. As such, their divergence from surface ancestors and eventual speciation is likely to be driven by the shift in ecology...
متن کاملGenome Editing Using TALENs in Blind Mexican Cavefish, Astyanax mexicanus
Astyanax mexicanus, a teleost fish that exists in a river-dwelling surface form and multiple cave-dwelling forms, is an excellent system for studying the genetic basis of evolution. Cavefish populations, which independently evolved from surface fish ancestors multiple times, have evolved a number of morphological and behavioral traits. Quantitative trait loci (QTL) analyses have been performed ...
متن کاملFeeding habits and stomach contents of Silver Sillago,
The study investigated the stomach content of Sillago sihama in Hormuzgan Province waters located in the northern Persian Gulf from October 2009 to March 2010. The stomach analysis was carried out using frequency of occurrence and numeric methods. Diatoms, blue- green algae and dinoflagellates constituted main food of plant origin. Diatoms were found to be the most preferable food of...

متن کاملExpanded expression of Sonic Hedgehog in Astyanax cavefish: multiple consequences on forebrain development and evolution.
Ventral midline Sonic Hedgehog (Shh) signalling is crucial for growth and patterning of the embryonic forebrain. Here, we report how enhanced Shh midline signalling affects the evolution of telencephalic and diencephalic neuronal patterning in the blind cavefish Astyanax mexicanus, a teleost fish closely related to zebrafish. A comparison between cave- and surface-dwelling forms of Astyanax sho...
