Evolutionary Dynamics of Pine Squirrels (Tamiasciurus) in Western North America
The evolution of new phenotypes and species is a population genetic process that is governed by four fundamental forces: natural selection, drift, mutation, and gene flow. Ecological genetics is the reciprocal interaction between population genetic theory and empirical observations from nature and the laboratory. Here I present ...
The evolutionary implications of alternative larval development in ascidians
Considering traits that facilitate and inhibit evolutionary diversification can best be done with traits where the genetic and developmental basis is known. My PhD. research has focused on the evolutionary implications of larval development in molgulid ascidians. Ascidians or sea squirts, are a group of tunicates, which ...
The systematics and evolution of Lantaneae (Verbenaceae), a molecular phylogenetic approach
Lantaneae are a morphologically variable group of 300-400 species, representing the largest tribe within Verbenaceae. They are widespread and diverse in the new world tropics and subtropics; some members are native to Africa, and others, most notably the <italic>Lantana camara</italic> complex, have spread across the globe ...
Embryonic xanthophore fate in the zebrafish, Danio rerio
Pigment patterns are one of the most diverse and visually appealing traits of any animal, playing important behavioral and ecological roles in mate choice, shoaling and predator avoidance. In the zebrafish, <italic>Danio rerio</italic>, these patterns result from the organization of neural crest derived pigment cells, offering ...
