Abstract
We evaluate the hypothesis that the vertical migration of Periphylla
periphylla is governed by its sensitivity to light intensity. By
applying an individual-based model where random walk is combined with
assumed individual responses to light, we compare the predicted vertical
distributions with acoustical observations. Important features of the
observed P. periphylla distributions can be explained by a simple
proximate light response where individual P. periphylla avoids light
above a certain threshold but also has a preference for very low light
intensities. In addition to accounting for the observed synchronous diel
vertical migration phenomenon in P. periphylla, this simple mechanism
also accounts for simultaneous asynchronous vertical migrations observed
for part of the population.
