Adviser Co-Adviser ii COLORADO STATE UNIV. LIBRARIES ABSTRACT OF THESIS THE ASSIMILATION AND ELIMINATION OF CESIUM BY FRESHWATER INVERTEBRATES Freshwater invertebrates are important vectors of radioactive cesium e34Cs and 137CS) in aquatic food webs, yet little is known about their cesium :uptake and loss kinetics. This study provides a detailed investigation of cesium assimilation and elimination by freshwater invertebrates. Using five common freshwater invertebrates (Gammarus lacustris, Anisoptera sp. nymphs, Claassenia sabulosa and Megarcys signata nymphs, and Orconetes sp.), a variety of food types (oligochaete worms, mayfly nymphs and algae) and six temperature treatments (3.5 to 30°C), the following hypotheses were tested: 1) cesium elimination rates are a positive function of water temperature; 2) cesium elimination rates increase with decreasing body size; 3) assimilation efficiencies range between 0.6 and 0.8 for diet items low in clay. Cesium loss exhibited first order, non-linear kinetics, best described by a two component exponential model. Cesium assimilation efficiencies were higher for invertebrates fed oligochaetes (0.77) and algae (0.80) than those fed mayfly nymphs (0.20).

Mr. J. Matt Tagg aided in the identification of the aquatic invertebrates. Ms. Leslie Ogden provided computer assistance. Several people at Dinosaur National Monument helped us immensely with various project details. Steve Petersburg, Dana Dilsaver, and Dennis Ditmanson provided us with our research permit. Ann Elder helped with sample archiving. Christy Wright scheduled our trip and provided us with our river permit. We thank them all for all their help and good spirit. We also thank Mr. Walter Kittams (National Park Service, Regional Office, Omaha Nebraska) and Mr. Earl M. Semingsen (Superintendent, Dinosaur National Monument) for funding the study and the members of the 1962 University of Utah expedition: Dr. Angus M. Woodbury, Dr. Stephen Durrant, Mr. Delbert Argyle, Mr. Douglas Anderson, and Dr. Seville Flowers for their foresight to conduct the original study nearly 40 years ago. The concept and value of long-term ecological data is often bantered about, but its value is never more apparent then when we conduct studies like that presented here.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

    Ephemeroptera, Plecoptera, Megaloptera, and Trichoptera of Great Smoky Mountains National Park

    The Great Smoky Mountains National Park All Taxa Biodiversity Inventory: A Search for Species in Our Own Backyard 2007 Southeastern Naturalist Special Issue 1:159–174 Ephemeroptera, Plecoptera, Megaloptera, and Trichoptera of Great Smoky Mountains National Park Charles R. Parker1,*, Oliver S. Flint, Jr.2, Luke M. Jacobus3, Boris C. Kondratieff 4, W. Patrick McCafferty3, and John C. Morse5 Abstract - Great Smoky Mountains National Park (GSMNP), situated on the moun- tainous border of North Carolina and Tennessee, is recognized as one of the most highly diverse protected areas in the temperate region. In order to provide baseline data for the scientifi c management of GSMNP, an All Taxa Biodiversity Inventory (ATBI) was initiated in 1998. Among the goals of the ATBI are to discover the identity and distribution of as many as possible of the species of life that occur in GSMNP. The authors have concentrated on the orders of completely aquatic insects other than odonates. We examined or utilized others’ records of more than 53,600 adult and 78,000 immature insects from 545 locations. At present, 469 species are known from GSMNP, including 120 species of Ephemeroptera (mayfl ies), 111 spe- cies of Plecoptera (stonefl ies), 7 species of Megaloptera (dobsonfl ies, fi shfl ies, and alderfl ies), and 231 species of Trichoptera (caddisfl ies). Included in this total are 10 species new to science discovered since the ATBI began. Introduction Great Smoky Mountains National Park (GSMNP) is situated on the border of North Carolina and Tennessee and is comprised of 221,000 ha. GSMNP is recognized as one of the most diverse protected areas in the temperate region (Nichols and Langdon 2007).

    Distribution of Trace Metals in Fine-Grained Bed Sediments and Benthic Insects in the Clark Fork River, Montana

    Distribution of Trace Metals in Fine-grained Bed Sediments and Benthic Insects in the Clark Fork River, Montana Ellen V. Axtmann *, Daniel J. Cain and Samuel N. Luoma U. S. Geological Survey 345 Middlefield Road, M.S. 465 Menlo Park, CA 94025 Abstract The downstream distribution of Cu, Cd, and Pb in fine-grained sediments and benthic insect larvae of the Clark Fork River, Montana is characterized. This river has been heavily con laminated as a result of past mining and smelling operations near its headwaters. Concentrations of all metals in bed sediments displayed a simple exponential downstream decrease through the upper 181 km of the river. The trend suggested metal contamination originated from source(s) in the headwaters, with physical dilution occurring downstream. Additional data suggested floodplain sediments also were contaminated by the original source(s). Secondary inputs from cutbanks in the floodplains may have extended the downstream influence of the contamination. The exponential model predicted that sediment contamination should extend at least 550 km downstream, a result that was verified with data from a separate, independent study. Metal contamination, as observed in all taxa of insect larvae collected from the upper Clark Fork. Concentrations in the insect larvae were highest in the upper 100 km of the river, but downstream trends were more complex than those of the sediments. Some differences in trends occurred among taxa and metals. Areas in the river of enhanced or reduced metal contamination also were apparent. Metal contamination, however, was still evident at 381 km, the most downstream station sampled. Metal concentrations in sediments and insects decreased at the confluences of uncontaminated tributaries, but the influence of tributaries on metal contamination in the Clark Fork River was localized, extending for only 1-2 kin below the confluences.

Hilsenhoff2 ABSTRACT Major improvements were made in using a biotic index of the arthropod fauna to evaluate organic stream pollution. All tolerance values were reevaluated, many were changed, and the scale for tolerance values was expanded to 0-10 to provide greatcr precision. Keys to larvae of Ceratopsyche have been developed and tolerance values for species in this important genus are provided. Sorting of samples in the laboratory instead of in the field is recommended, and directions for processing and evaluating samples are included. A "saprobic index" (Pantel and Buck 1955) and a "biotic indcx" (Chutter 1972) werc proposed for evaluating the water quality of streams through a study of their fauna.
