High major histocompatibility complex class I polymorphism despite bottlenecks in wild and domesticated populations of the zebra finch ()
(2015-12)
Background
Two subspecies of zebra finch, Taeniopygia guttata castanotis and T. g. guttata are native to Australia and the Lesser Sunda Islands, respectively. The Australian subspecies has been domesticated and is now an ...

Background
Two subspecies of zebra finch, Taeniopygia guttata castanotis and T. g. guttata are native to Australia and the Lesser Sunda Islands, respectively. The Australian subspecies has been domesticated and is now an ...
Color Pattern Evolution in the Threespine Stickleback (Gasterosteus aculeatus): Functional, Mechanistic and Synthetic Approaches
(East Carolina University, 2022-07-19)
Studies of animal color patterns have provided important insights into the nature of evolution and adaptation. Coloration may be the target of multiple evolutionary processes, including natural selection, intersexual ...
Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)
Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ...
Lateral Gene Transfer between Bacteria and Trichoderma reesei
(East Carolina University, 2012)
Lateral gene transfer (LGT) has played an important role in shaping the `tree of life'. It has promoted evolution by generating gene redundancies, which allow for more freedom in terms of allowed mutations in a genome, ...
Dodge, Duck, Dip, Dive & Dependence: Using Dodgeball to Explore Frequency Dependent Selection
(2016-09)
The term frequency dependence describes scenarios in which the likelihood
of an event occurring is strongly tied to how common a particular trait is.
Understanding frequency dependence is key to understanding ...
