Evolutionary and Ecological Factors Maintaining Apomixis in Boechera, a Wild Relative of Arabidopsis
What evolutionary processes and ecological patterns underlie the maintenance of asexual reproduction in natural populations? Although a vast body of literature offers theory to explain the existence of sexual and asexual ...
Mechanisms of Habitat Segregation Between Co-Occurring Monkeyflower Species
Closely related, ecologically similar species are often separated at a small scale while being broadly sympatric. In Northern California’s coast range two monkeyflower species, Mimulus guttatus and Mimulus nudatus co-occur ...
The Maintenance of Genetic Variation by Environmental Selection
Understanding forces creating or maintaining the vast amount of biodiversity has been a major task of biologists. Genetic variation plays a major role in the creation of biodiversity because in contrast to environmental ...
The Evolution and Genetics of Reinforcement in Phlox Drummondii
One of the major goals of evolutionary biology is understanding the process of species formation. There is particular interest in how selection can favor species formation through the process of reinforcement. When two ...
The Genetics of Adaptation to a Harsh Granite Outcrop Environment in Mimulus
Closely related populations or species often occupy ecologically disparate habitats. Adaptation to new habitats can maintain genetic variation within a species or eventually lead to speciation. Local adaptation to different ...
