Influence of Native Freshwater Mussel Functional Traits And INFLUENCE OF NATIVE FRESHWATER MUSSEL FUNCTIONAL TRAITS AND COMMUNITY STRUCTURE ON NITROGEN REMOVAL IN STREAM SEDIMENTS by ZACHARY LYNN NICKERSON CARLA L. ATKINSON, COMMITTEE CHAIR BEHZAD MORTAZAVI LISA DAVIS ROBERT H. FINDLAY A THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Biological Sciences in the Graduate School of The University of Alabama TUSCALOOSA, ALABAMA 2018 Copyright Zachary Lynn Nickerson 2018 ALL RIGHTS RESERVED ABSTRACT Animals physically and chemically modify their environment as a result of their functional traits. These effects are particularly influential in freshwater benthic environments where animal aggregations can impact the recycling and repackaging of major macronutrients. I examined the influence of native freshwater mussels (Bivalvia: Unionidae) on the removal of dissolved inorganic nitrogen (N) via the biogeochemical pathways of denitrification and annamox in freshwater sediments. In one experiment, I used continuous flow-through incubation + methods to assess the influence of individual mussel physiological traits (ammonium [NH4 ] excretion, organic matter [OM] biodeposition) on N-removal in stream sediments. In the second experiment of my thesis, I manipulated the biodiversity of mussel aggregations in their natural environment using in-situ stream benthic enclosures to assess the influence of mussel aggregations, associated functional traits, and the effect of mussel biodiversity on N-removal. + Incubation results showed NH4 excretion increased the ambient flux of dinitrogen gas (N2) across the sediment-water interface, while OM biodeposition increased the maximum N-removal potential in the sediment. Results of the in-stream enclosure experiment showed there were non- additive effects of mussel biodiversity on N-removal in stream sediments. Results suggested this effect was driven by an increase in biological activity (movement, burrowing), potentially driven by inter-specific competition among species with different niche requirements. My thesis research advances the field by linking specific mussel functional traits to an important ecosystem function, N-removal, and showing the importance of incorporating biodiversity into aggregate- scale studies of organisms’ influences on biogeochemical ecosystem processes. ii DEDICATION To my family, especially my parents Jeff and Sheryl, my siblings Tyler, Emily and Sydney, and my wonderful wife Anastasia, for their unending love and support. Also, to Drs. Joy O’keefe and Jennifer Latimer for fueling my passion for research. iii LIST OF ABBREVIATIONS AND SYMBOLS AFDM Ash-free dry mass AL Alabama ANCOVA Analysis of covariance ANOVA Analysis of variance Annamox Anaerobic ammonium oxidation ARW Artificial river water BD-EF Biodiversity-ecosystem function framework C Carbon C. asperata Cyclonaias asperata C.B.

    Rare Animal Fact Sheet IMBIV31060 Louisiana Department of Wildlife and Fisheries Natural Heritage Program Obovaria unicolor Alabama Hickorynut Identification: This mussel has a round or elliptical shape; shell is nearly smooth, shiny, brown to yellowish brown with rays, young shells are green with green rays; mother-of-pear is pink but sometimes white or blue. Measurements: A small mussel, 1.5 to 2 inches in length. Taxonomic comments: No recognized subspecies. Status: Global ranking is G3 and state rank is S1. Habitat: Sand and gravel bottoms in river systems. Range: Eastern gulf drainages throughout Alabama, Louisiana, Mississippi, and Oklahoma. Food habits*: Mussels are continually pumping water through their siphon. Their diet is composed of the various micropscopic plants and animals from the water and organic matter from stream bottoms that they filter from this water. Reproduction: Sexes are separate. No information on host fish available. Reason for decline: 1) The damming of stream and rivers results in the loss of mussel and host fish habitat. 2) Channelization of large stream habitat. 3) Declining water quality as a result of siltation (reduces oxygen level) and heavy recreational use of habitat. Interesting facts: This species is common only in the Sipsey River in Alabama. It is believed to have been uncommon or historically rare throughout the rest of its range. * Indicates generalized information for freshwater mussels in the absence of information specific to this species Rare Animal Fact Sheet IMBIV31060 Known distribution in Louisiana: Dates of documented observations are: 1977, 1979, 1988, and 1994 References McCullagh, W.H., J.D.

THOMAS WATTERS The Ohio State University, Department of Evolution, Ecology, and Organismal Biology 1315 Kinnear Road, Columbus, Ohio 43212, USA Abstract.—Catfi shes are important in freshwater ecosystems not only as consumers, but also as essential partners in symbiotic relationships with other organisms. Freshwater mol- lusks are among the many organisms that have interactions with catfi shes. For example, icta- lurids are hosts for larvae of several native freshwater mussel species. The larvae, which attach briefl y to gills or fi ns of fi sh to complete their development to the free-living juvenile stage, disperse via upstream and downstream movement of host fi sh. In turn, freshwater mussels serve as a food source for some catfi sh species while other catfi sh species may use spent mus- sel shells for habitat. Ictalurids also benefi t from the conservation status of many freshwater mussel species. Federal and state laws protecting these invertebrates can preserve water qual- ity and habitat and, at times, provide incentives and funding for conservation and restoration of stream and riparian habitats.

  • In Mississippi National Forests
    SUMMARY Little is known about the distribution of freshwater mussels in Mississippi national forests. Review of the scant available infor- mation revealed that the national forests harbor a diverse mus- sel fauna of possibly 46 or more species (including confirmed, probable, and potential occurrences). Occurrence of 33 species is confirmed. Because of the geographic, physiographic, and drain- age basin diversity of Mississippi national forests, there is con- siderable variation in mussel communities among the national forests. Three distinct fauna1 groups are represented in Missis- sippi national forests, each with a characteristic assemblage of species. One species of potential occurrence is a federally endan- gered species, 1 species of confirmed occurrence is a candidate for listing, and 11 species of confirmed or probable occurrence are considered of special concern by the American Fisheries Society (Williams and others 1993). None of the national forests have been surveyed adequately, and specific population data are almost com- pletely lacking. This review of existing information represents the first of a three-phase program needed to comprehensively evalu- ate the mussel resources of Mississippi national forests. Phase two involves an exhaustive, qualitative field survey of Mississippi national forests to document precise distribution of species and location of important communities. Phase three consists of a quan- titative study of important communities in order to assess repro- ductive characteristics and viability and to establish baseline density estimates for monitoring of future population trends.
