General research interests: My research focuses on the conservation of aquatic systems in the western and central U.S. Current and past projects can be classified into three general areas: 1) effects of global change on diversity-ecosystem function relationships in streams, 2) evaluation of patterns and processes regulating species diversity and habitat associations of fishes in streams and reservoirs, and 3) dynamics of non-coevolved fish assemblages.
My dissertation research focuses on the impacts of riverscape fragmentation on the distribution of imperiled Great Plains fishes. Specifically, I’m working with (1) the declining status of eight pelagic-spawning cyprinids as related to the fragmentation of large Great Plains rivers; (2) effects of barriers to dispersion on community composition within prairie stream fish communities; and (3) developing predictive models for the movement of fishes within dendritic ecological networks.

Erika Martin, PhD student (erikam86@k-state.edu). Ecological and ecosystem consequences of fish movement in a dynamic riverscape.My dissertation research focuses on evaluating how fish movement and riverscape dynamics affect prairie stream community structure and ecosystem properties. Current objectives are to evaluate (1) density-dependent interactions of prairie stream fish (2) priority effects and dominance hierarchies (if they occur, and how important are they) and 3) the influence of the environment on the fish community as well as the influence the fish have on their environment.
My general interests include anthropogenic disturbances, metacommunity ecology, and conservation biology. Erika's webpage
James Whitney, PhD student (jwhit@k-state.edu). Metacommunity dyanmics and life history constraints of native and nonnative fishes in the Gila River Species in the metacommunity differ in their dispersal aptitude, and these differences may be related to certain traits possessed by the species, such as life-history strategy. Native and nonnative fishes in the upper Gila River Basin of southwestern New Mexico show highly-divergent life-history strategies, thus potentially exhibiting different degrees of dispersal ability. These differences in dispersal ability could translate into variation in metacommunity structure across a longitudinal gradient of the upper Gila, and may be affecting species persistence across multiple spatial and temporal scales. Under a combined framework of metacommunity and life-history theory, the primary goals of my PhD research will be to quantify differences in dispersal ability among fishes exhibiting different life-history strategies in the upper Gila River, and to determine the influence of these dispersal differences on metacommunity structure and function.
Matthew Troia, PhD student (troiamj@k-state.edu). Niche Dynamics of Great Plains Fishes:
Contemporary Shifts, Niche Evolution, and Mechanistic Underpinnings
The objectives of my dissertation research are to quantify niche dynamics of Great Plains stream fishes and gain a mechanistic understanding of species–habitat relationships. First, I will examine niche shifts of populations that occur in different drainage basins and use phylogenetic relationships among species to examine how niche dimensions evolve. Understanding niche dynamics at both ecological and evolutionary time scales is important in predicting how species distributions’ will respond to climate change and habitat alteration. Secondly, I will carry out a series of experiments to quantify how several prominent environmental gradients influence the physiological performance of individuals (e.g., growth and body condition) and mediate interspecific interactions. Understanding which abiotic variables are causally linked to survivorship and population dynamics is necessary for producing niche and distribution models that can be extrapolated in time and space.

Stream faunas of the Great Plains are highly threatend by massive extraction of groundwater from the High Plains aquifer and fragmentation of rivers through impountments. Many species have declined and many are extirpated from their former range. We have developed a comprehesive geodatabase that includes georeferences datalayers of (1) stream networks and characteristics, (2) catchment geology and landcover and (3) point distribution data for fishes and mussels.
The experimental stream facility on Konza Prairie Biological Station provide a venue to manipulate stream biodiversity, nutrients, substrates, and many other aspects of streams. These manipulations can be used to test mechanistic hypotheses of main drivers of stream community structure and ecosystem function.
