More than 30 papers and posters were presented and much fruitful discussion occurred. An enjoyable field trip to the Colorado Rockies took place on Sunday, May 19th, and the weather was excellent. Boris was such a good host that it was difficult to leave, but many participants traveled to Santa Fe, New Mexico to attend the annual meetings of the North American Benthological Society. Bill Stark gave us a way to remember this meeting by producing a T-shirt with a unique “Spirit Fly” design. ANNOUNCEMENT 11th International Stonefly Symposium Stan Szczytko has planned and organized an excellent symposium that will be held at the Tree Haven Biological Station, University of Wisconsin in Tomahawk, Wisconsin, USA. The registration cost of $300 includes lodging, meals, field trip and a T- Shirt. This is a real bargain so hopefully many colleagues and friends will come and participate in the symposium August 17-20, 1992. Stan has promised good weather and good friends even though he will not guarantee that stonefly adults will be collected during the field trip. Printed August 1992 1 OBITUARIES RODNEY L.

  • Phylogeographic and Nested Clade Analysis of the Stonefly Pteronarcys
    J. N. Am. Benthol. Soc., 2004, 23(4):824–838 q 2004 by The North American Benthological Society Phylogeographic and nested clade analysis of the stonefly Pteronarcys californica (Plecoptera:Pteronarcyidae) in the western USA JOHN S. K. KAUWE1 Department of Biology, Washington University, St. Louis, Missouri 63110 USA DENNIS K. SHIOZAWA2 Department of Integrative Biology, Brigham Young University, Provo, Utah 84602 USA R. PAUL EVANS3 Department of Microbiology and Molecular Biology, Brigham Young University, Provo, Utah 84602 USA Abstract. Long-distance dispersal by aquatic insects can be difficult to detect because direct mea- surement methods are expensive and inefficient. When dispersal results in gene flow, signs of that dispersal can be detected in the pattern of genetic variation within and between populations. Four hundred seventy-five base pairs of the mitochondrial gene, cytochrome b, were examined to inves- tigate the pattern of genetic variation in populations of the stonefly Pteronarcys californica and to determine if long-distance dispersal could have contributed to this pattern. Sequences were obtained from 235 individuals from 31 different populations in the western United States. Sequences also were obtained for Pteronarcella badia, Pteronarcys dorsata, Pteronarcys princeps, Pteronarcys proteus, and Pter- onarcys biloba. Phylogenies were constructed using all of the samples. Nested clade analysis on the P. californica sequence data was used to infer the processes that have generated the observed patterns of genetic variation. An eastern North American origin and 2 distinct genetic lineages of P.californica could be inferred from the analysis. Most of the current population structure in both lineages was explained by a pattern of restricted gene flow with isolation by distance (presumably the result of dispersal via connected streams and rivers), but our analyses also suggested that long-distance, over- land dispersal has contributed to the observed pattern of genetic variation.

  • DISTRIBUTION, ECOLOGY, and REPRODUCTIVE BIOLOGY of the ORANGEFIN MADTOM (NOTURUS GILBERTI) by Timothy Dale Simonson
    DISTRIBUTION, ECOLOGY, AND REPRODUCTIVE BIOLOGY OF THE ORANGEFIN MADTOM (NOTURUS GILBERTI) by Timothy Dale Simonson Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Fisheries and Wildlife Sciences APPROVED: Richard J. Neves, Chair Dona:;[d J. Orth Johm J. Ney Louis A. Hel:frich April 1987 Blacksburg, Virginia DISTRIBUTION, ECOLOGY, AND REPRODUCTIVE BIOLOGY OF THE ORANGEFIN MADTOM (NOTURUS GILBERTI) by Timothy Dale Simonson Richard J. Neves, Chair Fisheries and Wildlife Sciences (ABSTRACT) Distribution of the orangefin madtom (Noturus gilberti) was determined from 347 sites sampled in Virginia and North Carolina. This species inhabited 264 stream kilometers, over twice the reported range, in the following systems: Craig Creek, Roanoke River, Dan River, Big Chestnut Creek, South Mayo River, Pigg River, and Smith River. The orangefin madtom was somewhat common; 33% (Dan River) to 70% (Craig Creek) of the sites sampled were occupied. Negative interspecific associates of orangefin madtoms included chubs, mountain redbelly dace, rosyside dace, crescent shiners, and crayfish; only Roanoke darters were considered positive associates. Sand and silt levels were significantly lower at sites with !L. gilberti, while per- centage of small cobble, local gradient, and depth were sig- nificantly higher. Discriminant function analysis identified large gravel, local gradient, silt, and occurrence of rosyside dace and crayfish, as significant predictors of the occurrence of the orangefin madtom. Seasonal samples from Craig Creek consisted of three age groups. The smallest individual captured was 33 mm total length (TL) and the largest was 111 mm TL.

  • (Trichoptera: Limnephilidae) in Western North America By
    AN ABSTRACT OF THE THESIS OF Robert W. Wisseman for the degree of Master ofScience in Entomology presented on August 6, 1987 Title: Biology and Distribution of the Dicosmoecinae (Trichoptera: Limnsphilidae) in Western North America Redacted for privacy Abstract approved: N. H. Anderson Literature and museum records have been reviewed to provide a summary on the distribution, habitat associations and biology of six western North American Dicosmoecinae genera and the single eastern North American genus, Ironoquia. Results of this survey are presented and discussed for Allocosmoecus,Amphicosmoecus and Ecclisomvia. Field studies were conducted in western Oregon on the life-histories of four species, Dicosmoecusatripes, D. failvipes, Onocosmoecus unicolor andEcclisocosmoecus scvlla. Although there are similarities between generain the general habitat requirements, the differences or variability is such that we cannot generalize to a "typical" dicosmoecine life-history strategy. A common thread for the subfamily is the association with cool, montane streams. However, within this stream category habitat associations range from semi-aquatic, through first-order specialists, to river inhabitants. In feeding habits most species are omnivorous, but they range from being primarilydetritivorous to algal grazers. The seasonal occurrence of the various life stages and voltinism patterns are also variable. Larvae show inter- and intraspecificsegregation in the utilization of food resources and microhabitatsin streams. Larval life-history patterns appear to be closely linked to seasonal regimes in stream discharge. A functional role for the various types of case architecture seen between and within species is examined. Manipulation of case architecture appears to enable efficient utilization of a changing seasonal pattern of microhabitats and food resources.

  • This Table Contains a Taxonomic List of Benthic Invertebrates Collected from Streams in the Upper Mississippi River Basin Study
    This table contains a taxonomic list of benthic invertebrates collected from streams in the Upper Mississippi River Basin study unit as part of the USGS National Water Quality Assessemnt (NAWQA) Program. Invertebrates were collected from woody snags in selected streams from 1996-2004. Data Retreival occurred 26-JAN-06 11.10.25 AM from the USGS data warehouse (Taxonomic List Invert http://water.usgs.gov/nawqa/data). The data warehouse currently contains invertebrate data through 09/30/2002. Invertebrate taxa can include provisional and conditional identifications. For more information about invertebrate sample processing and taxonomic standards see, "Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory -- Processing, taxonomy, and quality control of benthic macroinvertebrate samples", at << http://nwql.usgs.gov/Public/pubs/OFR00-212.html >>. Data Retrieval Precaution: Extreme caution must be exercised when comparing taxonomic lists generated using different search criteria. This is because the number of samples represented by each taxa list will vary depending on the geographic criteria selected for the retrievals. In addition, species lists retrieved at different times using the same criteria may differ because: (1) the taxonomic nomenclature (names) were updated, and/or (2) new samples containing new taxa may Phylum Class Order Family Subfamily Tribe Genus Species Taxon Porifera Porifera Cnidaria Hydrozoa Hydroida Hydridae Hydridae Cnidaria Hydrozoa Hydroida Hydridae Hydra Hydra sp.
