Age effects on reproductive behavior in the treehopper umbonia crassiscornis (Hemipera: membracidae)
(University of Missouri--Columbia, 2007)
In many animal species females select mates based on male age. This choice is often linked to the reproductive benefits females derive. Age-based choice is also influenced by variation in the ability of males to find and ...

(University of Missouri--Columbia, 2007)
as flocking behavior and flight mode) of an assemblage of migratory birds composed of 33 species of nine families in order to understand why these birds are funneled through this area. I also describe the magnitude of these migrations, their inter...
Beyond the edge : riparian habitat use and forest management effects on stream salamanders in the southern Appalachian mountains
(University of Missouri--Columbia, 2007)
habitat use and abundance. Additionally, we must determine the effects of forest management practices, such as timber harvesting, have on amphibian populations in order to develop alternative management strategies. My data show that core terrestrial...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg ...
Characterizing territoriality and the mechanisms that mediate it in female Anolis gundlachi lizards
(University of Missouri--Columbia, 2019)
Territoriality is a suite of behaviors through which animals secure access to particular areas or resources. It is prevalent across animal groups and has the potential to exert substantial influence on fitness by mediating ...
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)
Sturgeon populations are imperiled worldwide. Declines are attributed to many factors including habitat degradation and alteration, overexploitation, and contamination. In North America, white sturgeon (Acipenser transmontanus) ...
