Sperm size and sperm competition in birds.

Proceedings. Biological sciences - 22 Feb 1992

Briskie J V, Montgomerie R

Abstract excerpt

In a sample of 20 species of North American passerine birds we found no relation between sperm size and mating system like that previously reported in mammals (Gomendio & Roldan (Proc. R. Soc. Lond. B 243, 181 (1991)). Instead, we found a positive correlation between sperm length and the length of female sperm storage tubules (SSTS) and a negative correlation between sperm length and the number of SSTS. Both of...
