Evolution of an adaptive behavior and its sensory receptors promotes eye regression in blind cavefish
(Springer Nature, 2013-07-11)
How and why animals lose eyesight during adaptation to the dark and food-limited cave environment has puzzled biologists since the time of Darwin. More recently, several different adaptive hypotheses have been proposed to ...
Enhanced prey capture skills in Astyanax cavefish larvae are independent from eye loss
(Springer Nature, 2014-10-03)
Enhanced food-finding efficiency is an obvious adaptive response to cave environments. Here, we have compared the food-finding abilities of Astyanax surface fish and blind cavefish young larvae in their first month of life, ...
Ascidian gene-expression profiles
(Springer Nature, 2002-09-25)
With the advent of gene-expression profiling, a large number of genes can now be investigated simultaneously during critical stages of development. This approach will be particularly informative in studies of ascidians, ...
Distinct genetic architecture underlies the emergence of sleep loss and prey-seeking behavior in the Mexican cavefish
(Springer Nature, 2015-02-20)
Sleep is characterized by extended periods of quiescence and reduced responsiveness to sensory stimuli. Animals ranging from insects to mammals adapt to environments with limited food by suppressing sleep and enhancing ...
The role of a lens survival pathway including sox2 and αA-crystallin in the evolution of cavefish eye degeneration
(Springer Nature, 2014-08-28)
The teleost Astyanax mexicanus is a single species consisting of eyed surface-dwelling (surface fish) and blind cave-dwelling (cavefish) morphs. Cavefish eyes are lost through apoptosis of the lens, which in turn promotes ...
