Introduction
I am an Assistant Professor in the Department of Biology at Southeast Missouri State University. ​I am an aquatic ecologist broadly interested in food webs and spatial subsidies, in particular, resource subsidies between aquatic and terrestrial ecosystems and how these fluxes affect communities in recipient systems.

Article
Aquatic habitats are closely linked to surrounding terrestrial systems via reciprocal subsidies. Much of the research on aquatic–terrestrial subsidies has focused on streams and lakes, while subsidies across aquatic–terrestrial boundaries of other systems, like temporary ponds, have received less attention. To address the lack of information regard...
Article
• Resource subsidies across aquatic‐terrestrial boundaries can alter predator distribution and biomass and elicit trophic cascades. Most studies have focused on the size of cross‐boundary fluxes, but the impact of a subsidy is also mediated by quality and relative abundance of similar resources in the recipient habitat. • Long‐chain polyunsaturated...
Article
• Resource subsidies of energy and nutrients can be transported via physical forces, such as gravity, wind or water and biotic processes, such as animal migration or emigration. Migratory transport of nutrient subsidies may be associated with reproductive processes, such as the deposition of eggs or emigration of juveniles to adult habitats. • We q...
Article
Subsidies across aquatic–terrestrial boundaries can alter consumer distributions and physiology. The importance of subsidies is a function of export quantity and of their physiological significance and relative scarcity in the recipient system. Aquatically derived long-chain polyunsaturated fatty acids (LC-PUFAs) are physiologically essential, rela...

Exposure to environmental stressors alters animal phenotypes as well as nutrient metabolism, assimilation, and excretion. While stress-induced shifts in nutrient processes are known to alter organismal carbon (C) and nitrogen (N) stoichiometry, there has been little exploration of how environmental factors influence phosphorous (P). A better unders...

Large river systems are inextricably linked with social systems; consequently management decisions must be made within a given ecological, social, and political framework that often defies objective, technical resolution. Understanding flow-ecology relationships in rivers is necessary to assess potential impacts of management decisions, but transla...
Article
Taxonomic and functional diversity in freshwater habitats is rapidly declining, but we know little about how such declines will ultimately affect ecosystems. Neotropical streams are currently experiencing massive losses of amphibians, with many losses linked to the chytrid fungus, Batrachochytrium dendrobatidis (Bd).We examined the ecological conse...

Maximizing the reduction of nitrate to dinitrogen gas (denitrification) has been advocated as a means to decrease nitrate pollution that causes eutrophication and hypoxia in estuaries worldwide. Managing this flux in bottomland forest wetlands of the Mississippi River could potentially reduce the world's second largest hypoxic zone. We used publish...
