Effects of Avian Predators on Stream Fish Assemblages
… chapter focuses on foraging behavior of kingfishers and great blue herons, and shows that netting and perches can be used to successfully manipulate avian predation pressure. The third chapter uses this technique to examine what effects kingfishers and wading birds are having on stream fish …

The Role of Physiography in the Relationships Between Land Cover and Stream Fish Assemblages
… land use has been linked to the degradation of streams and stream biota. Natural physical and climatic characteristics, or physiographic template, are important for determining natural land cover and constraining human land use, and are strongly related to stream habitat and stream biotic …

Patterns of Taxonomic, Functional, and Phylogenetic Diversity, and Ecological Drivers of Stream Fish Assemblages in East Texas
… supporting some of the greatest freshwater fish diversity in the state. Given the heterogeneity of habitats and species diversity, these rivers serve as excellent natural systems for examining the ecological processes shaping biodiversity patterns and species distributions. In 2023-2024, 60 …

Physical and Biological Impacts of Gravel Mining on Three Southwest Missouri Streams
… that is based on physically removing gravel from stream channels and flood plains. It is well documented that gravel mining negatively impacts streams in many different ways, including alternations in habitat, flow, and the biological community. For my research I focused on determining possible …

Influence of stream connectance and network spatial position on fish assemblage structure in the Kansas River basin, USA
Stream networks provide complex habitats for fish assemblages that can vary gradually along a gradient of stream size or abruptly at transition zones between large rivers and their tributaries. We evaluated the relative importance of these gradual and abrupt habitat transitions in regulating stream …

Effects of stream network topology on fish assemblage structure and bioassessment sensitivity in the mid-Atlantic highlands, USA
Stream fish assemblages exist within stream networks defined by the size and proximity of connected streams (i.e., stream network topology). The spatial position of sites within stream networks may therefore regulate opportunities for fish dispersal to access distant resources or colonize "new" …
