Eihab completes his Master degree
Eihab has been studying how shape and colour have changed in experimentally harvested guppy populations.
Eihab succesfully defended his thesis "Fisheries-induced evolution in morphology: A selection experiment on the Trinidadian guppy (Poecilia reticulata)" on June 10, 2016. Eihab found that there have been significant changes in both shape and colouration over time, although most of these changes are parallel between the treatments, suggesting that adaptation to the experimental aquaria have been important. However, males subject to positively size-selective fishing have increased in orange colour, as predicted by the theory.
