The descriptions and the data on the following pages may change without warning as data becomes available and as the systematics of the Plecoptera is revised or corrected. Every attempt is made to keep information up to date with current trends in stonefly research with periodic revisions. However, due to resource allocations, changes to this manual may not proceed in a timely manner. Acknowledgements This manual would not exist if not for the early efforts of former BAU supervisor Trish McPherson to get her biologists on the same page. The taxonomic, field, and mental prowess of current BAB benthic biologists Eric Fleek, Victor Holland, Michael Walters, and Larry Eaton, was instrumental in obtaining and validating data and providing rigor to the descriptions provided herein. Former BAB biologists Tracy Morman, Deirdre Black, Bill Crouch, Blair Prusha, Larry Ausley, Richard Thorp, Cathy Tyndall, and Dave Penrose collected and identified much of the material utilized in this manual. For field sampling and sample processing, including the digging out of old specimens, the efforts of Mike Turner, Matt Stillwell, Michelle Simonson, and Michael Shepard are appreciated. Mark Hale deserves special mention for providing database and GIS assistance for difficult and unwieldy datasets. Also I thank the many systematic and stonefly experts that have weighed in on this manual, or earlier versions, either by providing verifications, additional taxonomic characters for identification, taxonomic and locational data, comments, specimens, or rearing advice: Boris Kondratieff, Bill P. Stark, Stan Szczytko, and John Sandberg. Much of the information contained in this document would remain a mystery if not for the myriad number of stonefly workers across the world who provided the foundation and the keystones to the body of Plecoptera work that currently exists and on which this manual was based. Lastly, many records and specimens for taxa contained in this manual (and for some the only records and specimens known) as well as valuable comments were provided by Dave Lenat, former BAB aquatic biologist, creator of North Carolina’s Biotic Index. CONTENTS Families and genera of Plecoptera known to occur in North Carolina. A name in ( ) indicates that the NC DWR Biological Assessment Branch has no nymphal records for that genus.

A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Biological Sciences University of Alaska Fairbanks August 2017 APPROVED: Pat Doak, Committee Chair Greg Breed, Committee Member Colleen Handel, Committee Member Christa Mulder, Committee Member Kris Hundertmark, Chair Department o f Biology and Wildlife Paul Layer, Dean College o f Natural Science and Mathematics Michael Castellini, Dean of the Graduate School ABSTRACT Across the Arctic, taller woody shrubs, particularly willow (Salix spp.), birch (Betula spp.), and alder (Alnus spp.), have been expanding rapidly onto tundra. Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

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.

Although these medically important Rickettsia are often transmitted via haematophagous arthropods, other Rickettsia, such as those in the Torix group, appear to reside exclusively in invertebrates and protists with no secondary vertebrate host. Importantly, little is known about the diversity or host range of Torix group Rickettsia.

  • Empirically Derived Indices of Biotic Integrity for Forested Wetlands, Coastal Salt Marshes and Wadable Freshwater Streams in Massachusetts
    Empirically Derived Indices of Biotic Integrity for Forested Wetlands, Coastal Salt Marshes and Wadable Freshwater Streams in Massachusetts September 15, 2013 This report is the result of several years of field data collection, analyses and IBI development, and consideration of the opportunities for wetland program and policy development in relation to IBIs and CAPS Index of Ecological Integrity (IEI). Contributors include: University of Massachusetts Amherst Kevin McGarigal, Ethan Plunkett, Joanna Grand, Brad Compton, Theresa Portante, Kasey Rolih, and Scott Jackson Massachusetts Office of Coastal Zone Management Jan Smith, Marc Carullo, and Adrienne Pappal Massachusetts Department of Environmental Protection Lisa Rhodes, Lealdon Langley, and Michael Stroman Empirically Derived Indices of Biotic Integrity for Forested Wetlands, Coastal Salt Marshes and Wadable Freshwater Streams in Massachusetts Abstract The purpose of this study was to develop a fully empirically-based method for developing Indices of Biotic Integrity (IBIs) that does not rely on expert opinion or the arbitrary designation of reference sites and pilot its application in forested wetlands, coastal salt marshes and wadable freshwater streams in Massachusetts. The method we developed involves: 1) using a suite of regression models to estimate the abundance of each taxon across a gradient of stressor levels, 2) using statistical calibration based on the fitted regression models and maximum likelihood methods to predict the value of the stressor metric based on the abundance of the taxon at each site, 3) selecting taxa in a forward stepwise procedure that conditionally improves the concordance between the observed stressor value and the predicted value the most and a stopping rule for selecting taxa based on a conditional alpha derived from comparison to pseudotaxa data, and 4) comparing the coefficient of concordance for the final IBI to the expected distribution derived from randomly permuted data.

In 1997, collecting was done in and around Rock Island in an effort to collect Alloperla roberti. During April, May, and June of 2002, collecting for spring emerging stoneflies was conducted at nine sites along the Rock River from Rock Island to Rockton. Historically, 25 species of stoneflies (Insecta: Plecoptera) have been reported from the Rock River. Based on collecting from 1990-2002 eleven species (Acroneuria abnormis, Allocapnia granulata,Allocapnia vivipara Isoperla bilineata, Isoperla richardsoni,Perlesta golconda, Perlesta decipiens, Perlinella ephyre, Pteronarcys pictetii, Taeniopteryx burksi, Taeniopteryx nivalis) remain established within the Rock River. Acroneuria abnormis was previously very abundant along the length of the Rock River, but now is considered very rare. Allocapnia vivipara, the most common species of stonefly in Illinois and primarily a small stream species, appears to have been replaced by Allocapnia granulata in the Rock River.
