Environmental (natural and anthropogenic) effects on host-parasite (snail-trematode) interactions
(2016-05)
This dissertation explored environmental effects on host-parasite interactions. Chapter 2 was published in Ecotoxicology and assessed the effects of the herbicide atrazine on freshwater snails. The results indicated that ...
Studies on the stoichiometry of sexual dimorphism in Hyalella amphipods
(2016-07)
Understanding the causes and consequences of variation in across multiple levels of biological organization is a central goal in modern biology. Research integrating key ecological and evolutionary processes necessitates ...
Individual variation in testosterone levels and parental care in eastern bluebirds (Sialia sialis): Interactions with reproductive success and offspring traits
(2016-07)
Hormones are important regulators of behavior and fitness. We have learned much about the direct effects of hormones on behavior and reproductive success from studies that experimentally manipulate hormone levels. To ...
Methods for predicting environmentally-relevant concentrations of pulsed aquatic exposures
(2016-05)
Most current-use pesticides have short half-lives in the water column and thus the most relevant exposure scenarios for many aquatic organisms are pulsed exposures. However, it is frequently challenging to measure exposure ...
