The evolution and benefits of nest association and other reproductive strategies in North American minnows (Cyprinidae)
With over 293 species, Cyprinidae (minnows) is the largest family of fishes in North America. Although a diverse group of obvious ecological importance, very little is known about the life histories of North American minnows, including reproductive behavior. In order to promote understanding of the …
