Five Natural Hybrid Combinations in Minnows (cyprinidae)

Published in the early 1960s, 'Five Natural Hybrid Combinations in Minnows' by Frank B. Cross examines natural hybridization within the Cyprinidae family in North America. The book details five specific hybrid combinations, such as between 'Chrosomus erythrogaster' and 'Notropis cornutus frontalis', highlighting their unique anatomical traits and the role of environmental factors, particularly drought, in facilitating these hybrids. This study enhances the understanding of fish diversity and ecology in response to changing environmental conditions.
