Astyanax surface and cave fish morphs
(Springer Nature, 2020-07-11)
The small teleost fish Astyanax mexicanus has emerged as an outstanding model for studying many biological topics in the context of evolution. A major attribute is conspecific surface dwelling (surface fish) and blind cave ...
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, ...
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 ...
