Latitudinal patterns in the morphologic diversification of the neogene planktonic foraminifera
Statistical analysis of a literature-based compilation of phylogenetic relationships and biometric measurements of 136 Neogene planktonic foramhiferal species yielded well defined relationships between latitude and morphology. It was found that keel development is a significant factor in latitudinal...
