Charts and Tables
  1. Phylogeny for St Croix River unionids based on Bayesian analysis of nicotinamide adenine dinucleotide dehydrogenase subunit 1 (ND1) data set. Stars indicate ≥≥95%% posterior probability. Gray boxes indicate clades containing juvenile mussels retrieved from naturally infested fishes. Associated icons indicate fish species.

    A DNA-barcoding approach to identifying juvenile freshwater mussels (Bivalvia:Unionidae) recovered from naturally infested fishes

  2. The relationships between average mussel catch-per-unit-effort (CPUE) and the superpopulation estimate for each habitat and primary sampling period for Alasmidonta arcula (A), Lampsilis dolabraeformis (B), Lampsilis splendida (C), and Pyganodon gibbosa (D). Lines are least-squares fits, and the coefficient of determination for each species is shown in the upper right corner. Superpopulation estimates were calculated using model-averaged estimates of surface population size and temporary emigration.

  3. Seasonal abundance of glochidia of short-term (A, B) and long-term (C, D) brooders in the drift in the Sipsey River, Alabama. To reduce clutter and to accommodate the wide variation in individual species abundances, species within each brooding strategy were plotted in either a high- (A, C) or low- (B, D) abundance group (1 or 2, respectively). The dashed line on the bottom panel represents water temperature.

    My research interests are in the areas of freshwater ecology and conservation biology. Within these two broad areas my students and I are pursuing a variety of basic and applied ecological questions using benthic organisms as models. Much of my recent work focuses on freshwater mussels, a group where 70% of the North American species are considered threatened. Mussels are keystone species in many rivers and their catastrophic decline may lead to the decline of other faunas and the alteration of river ecosystem processes. In my research I am combining experimental and comparative approaches to examine the functional role of mussels in rivers and to determine the mechanisms underlying their distribution and abundance.

    I conduct and supervise research related to the effects of environmental pollutants, with emphasis on fish and invertebrates as model systems, and infer results to human health and ecological risk assessment. Research is performed at the organismal, population, community, and ecosystem levels of organization, which includes the effects of environmental pollutants on reproduction and development, biomarker development, and the fate, bioavailability, and transport of contaminants. Major areas of research include: 1) assessment of pesticides, persistent organochlorine contaminants, and metals in surface waters, 2) effects of waterborne and sediment-associated contaminants on fish and unionid mussels in inland waterways, 3) efficacy of constructed weltlands and other Best Manangement Practices (BMPs) for reducing non-point source pollution from urban (e.g., polycyclic aromatic hydrocarbons) and agricultural (e.g., nutrients) watersheds, and 4) the effects of contaminants on threatened and endangered species of fish and mussels.

    My main research interests focus on the physiological ecology and population bioenergetics of freshwater and marine invertebrates, particularly gastropod and bivalve mollusks. My research areas include the biology and control of nonindigenous aquatic invertebrates such as zebra mussels and Asian clams, the effects of climatic warming including thermal effluents on the energetic allocation patterns of aquatic invertebrates, physiological responses of marine and freshwater invertebrates to environmental stress, the physiological basis of zonation in intertidal marine invertebrates, development of environmentally sound nonchemical controls for invertebrate macrofouling of raw water systems and the analysis of potential human vectors for transport of aquatic invasive species between isolated drainage systems.
