Avian species have inspired numerous studies on ornamentation, exploring its role in intra- and intersexual selection as a marker for individual quality. Male birds have been the focus of most of these studies while females, which can also display ornamentation, have been studied less. Coloration achieved through molt, particularly carotenoid-based pigments, requires energy derived from food resources. As climate affects insect abundance, there may be a link between climate conditions during molt and feather quality the following season. We assessed the relationship between temperature and precipitation during molt and female Prothonotary Warbler (Protonotaria citrea) breast and crown feather reflectance metrics …

Undergraduate Research Symposium 2018
Amphibians are the fastest known declining taxonomic group in the world with 48% of populations in decline (Stuart et. al. 2004). These declines in amphibian populations are partially due to the lack of basic life history data (Semlitsch 2003). For example, amphibians are known for their bright coloration and ability to rapidly change color. Coloration is key to amphibian survival in terms of defense (as camouflage or a warning sign to predators), thermoregulation (darker skin warms faster), and communication (primarily mating displays) (Rudh and Qvanstrom 2013). One aspect of amphibian coloration that is poorly understood is how much the environment …
