| Abstract |
The environmental conditions under which strobilation of Aurelia scyphistomæ occurs are incompletely understood. Berrill in a review suggests three factors as being of particular significance: a heavy diet of suitable food prior to metamorphosis; a definite, low critical temperature, usually the winter minimum; and a good supply of food and oxygen at the critical period. Thiel, as a result of observations on naturally-occurring populations of scy-phistomæ, largely supports these suggestions and places particular emphasis on the food supply prior to strobilation. Laboratory experiments have produced conflicting results. |
