Sperm concentration and fertilization rate in Bufo arenarum (Amphibia: Anura).

Cabada MO .


???displayArticle.abstract???
The influence of sperm concentration upon the fertilization rate of Bufo arenarum oocytes was determinated. The experimental results were analysed according to the theories of Rothschild and Swann, and Hultin and Hagström for Psammechinus miliaris. The experimental results agreed with the predictions of the latter theory. Since Bufo arenarum and Psammechinus miliaris oocytes differ in both size and disposition of jelly envelopes, the postulations of Hultin and Hagström''s theory appear to have a general validity.
