Abstract

An open, flow-through system with diurnally fluctuating temperature regimes has been designed to study growth and developmental dynamics of benthic macroinvertebrates. Animals are kept in five sets of plastic troughs and trays arranged in a longitudinal series and separated by polyethylene-lined warming pools. Five diurnally oscillating temperature regimes of various magnitudes are produced depending on pool size. The magnitudes of the temperature pulse are quite predictable for each regime.
