Multispecies Character Displacement In Mexican Poeciliopsis Fishes, Andrea J. Roth
Multispecies Character Displacement In Mexican Poeciliopsis Fishes, Andrea J. Roth
Theses and Dissertations
Competition has long been recognized as a central force in shaping evolution, particularly through character displacement. Yet research on character displacement is biased as it has focused almost exclusively on pairs of interacting species while ignoring multispecies interactions. Unfortunately, communities are seldom so simple that only pairs of species interact, and it is not clear if inferences from pairwise interactions are sufficient to explain patterns in nature. A more realistic approach is to ask how traits evolve when multiple species interact. Here I explore the importance of multispecies competitive interactions on trait evolution in four congeneric species of livebearing fishes …
Phylogenetic History Of The Amy Gene Cluster In Catarrhines, Christian M. Gagnon
Phylogenetic History Of The Amy Gene Cluster In Catarrhines, Christian M. Gagnon
Theses and Dissertations
This study phylogenetically analyzed 30 AMY-related genes from 11 primates. The results show the gradual expansion of the AMY gene family which could have allowed primates to adapt to various ecological landscapes and maximize energy intake from starch-rich foods in periods of food scarcity.
