✦ Synopsis

The periods of dark and light to which an organism is exposed profoundly influence reproductive activity of widely differing forms i.e., induction of dormancy in plants and animals, spermatogenesis and spawning in fish, ovulation and related behavior in birds, floral initiation and seed germination in plants. (Withrow, '59 and Cold Spring Harbor Symposium, '60. ) A typical brachionid life cycle is presented in figure . Brachionus rubens usually reproduces parthenogenetically; the fe-~~~ ~ ~~ laid.

A salinity dependent mictic response was observed in a clone of Brachionus plicatilis cultured in the 2 to 4%0 salinity range. This response was related to asexual exponential reproduction rates (G) and could be divided into three categories: (a) no mixis occurred at a salinity of 35%0 S and above,
