of the many amphibian species for which stage-specific data are lacking. Next, I reared larvae of five species (A. annulatum, A. maculatum, A. opacum, A. talpoideum, and A. texanum) from populations along an ~200 km latitudinal gradient in Missouri, USA...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use

, Missouri, and South Carolina are determining the effects of timber harvest on the persistence of amphibian populations. The purpose of my dissertation research was to define adult wood frog nonbreeding habitat in continuous oak-hickory forest...
Nectar in nicotiana : pollinator associations, sources of variation, and evolutionary consequences
(University of Missouri--Columbia, 2007)
genetic basis. However, some differences in trait means and genotype by environment interactions were detected between the novel environment in which the experiment was conducted (Missouri), and the ancestral habitat of this species (Brazil). Therefore...
