Effects of gamete traits on fertilization in the sea and the evolution of sexual dimorphism
Article Abstract:
The success of fertilization in sea urchins depends on differences in gamete characteristics. Field studies show that gamete features and environmental conditions affect the differences in fertilization success. Gamete dispersal due to sea conditions accounts for only 21% of the differences. Natural selection is an important determinant for both male and female gametes. Natural selection for greater fertilization success allows the evolution of sexual dimorphism and anisogamy.

Solitary wave behaviour of sand dunes
Article Abstract:
