Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back. I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood and I— I took the one less traveled by, And that has made all the difference. Robert Frost The Road Not Taken, 1920 ACKNOWLEDGMENT Over the past twelve years I have received support and encouragement from a great number of individuals. First, I would like to thank my dissertation advisory committee of Drs. Julie Wolin (CSU), Robert Krebs (CSU), Joe Keiper (VMNH), and Mike Walton (CSU) who helped me as I moved from the idea of stonefly natural history to a complete dissertation. I would also like to thank Dr. Pete Clapham (CSU) for taking on the role as the internal examiner and Dr. Karen Munroe (BWU) who took the position of the external examiner. I thank the Cuyahoga Valley National Park, Cleveland Metroparks, and Holden Arboretum for permission to use their land as sampling sites. Financial support to conduct laboratory work was provided by the Department of Biological, Geological, and Environmental Sciences, the College of Science and Health Careers Doctoral Dissertation Improvement Grant, Cleveland Natural History Museum, the Shoemaker Foundation, and research funds of Julie Wolin and Robert Krebs. Insect collecting equipment was largely provided by Michael Yasick. I would also like to thank my family and extended families as my main support structure of this program. To Michael and Carol Yasick, you are everything to me, I will never be able to give back a gram of your support, from constant encouragement, financial support, and providing a place to run and hide when it got too much. But most of all both of you provided me with love, wisdom, guidance, and inner strength that gave me the determination and endurance to keep moving forward. I thank Michelle Yasick- Craft for always being there and listening to me; your advice has helped more than you know. I thank David Cronin, my soul mate for helping me find light at the end of the tunnel. Without his devotion, encouragement, and excellent editing skills, I would have never finished. You are and always will be the positive reaction to my negative action. To my friends who helped me along the way, especially Kristen Hopson. Although we had a few close calls when I almost lost you in snow piles and fast moving water, you always agreed to go back out. Finally I want to thank my silent partners: Fidget, Beauregard, and Tesse and to those I lost along the way: Chester, Buster, and Shiloh. DISPERSAL CAPABILITIES OF TWO PLECOPTERAN SPECIES AND MACROINVERTEBRATE COMMUNITY FROM FOUR WATERSHEDS IN NORTHEAST OHIO. ALISON L. YASICK ABSTRACT This dissertation focused on the insect order Plecoptera, and hypothesized that Allocapnia recta populations would have lower genetic diversity than Leuctra tenuis between adjacent Chagrin and Grand Rivers due to wing structure and season of terrestrial adult emergence. Genetic variations within the 16s rRNA region of mtDNA in A. recta , a winter emerging adult with rudimentary wing structure, and L. tenuis , a summer emerging adult with fully developed wings, were compared and revealed significant genetic variability between A. recta samples from the two rivers (F ST = 0.20) but not between L. tenuis samples (F ST = 0.07). Further genetic variation investigation used A. recta , populations, within and between the Chagrin River and Grand River, hypothesized that differences in populations is a function of distance, and that greater distance leads to greater genetic variability. To strengthen the robustness of this work, samples were collected from two additional watersheds, the Rocky and Cuyahoga Rivers. Genetic variation of A. recta populations differed significantly across all four watersheds, especially between the Cuyahoga and Grand Rivers (G´ ST = 1), Rarity of movement regardless of distance suggests that other factors have a more profound effect than previously thought – factors that include human influences. The unresolved genetic variation of A. recta and potential human influence resulted in a holistic examination of macroinvertebrate community structure and ecology within the four watersheds. Both legacy land use and anthropogenic disturbance effects on seasonal variation vi were examined and it was hypothesized that: (1) greatest species diversity and richness among stoneflies and other macroinvertebrates will occur during the summer months, when weather conditions in Ohio are more conducive. (2) The greatest species diversity and richness among stoneflies and other macroinvertebrates will occur where the landscape has been historically less disturbed. The results revealed inconsistencies in seasonal diversity between sites; regardless of legacy land-use and anthropogenic influence. Results of this research show the significance of examining both aquatic and terrestrial stages in order to collect accurate and robust data on macroinvertebrate community structure. Furthermore, year-long macroinvertebrate sampling must be conducted even during extreme events in order to construct a better understanding of macroinvertebrate communities. vii TABLE OF CONTENTS ABSTRACT ....................................................................................................................... v LIST OF TABLES ........................................................................................................... xii LIST OF FIGURES ....................................................................................................... xiii CHAPTER I.

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.

  • Testing Trade-Offs in Dispersal and Competition in a Guild of Semi-Aquatic Backswimmers
    Testing Trade-Offs in Dispersal and Competition in a Guild of Semi-Aquatic Backswimmers by Ilia Maria C. Ferzoco A thesis submitted in conformity with the requirements for the degree of Master of Science Graduate Department of Ecology and Evolutionary Biology University of Toronto © Copyright 2019 by Ilia Maria C. Ferzoco Testing Trade-Offs in Dispersal and Competition in a Guild of Semi-Aquatic Backswimmers Ilia Maria C. Ferzoco Master of Science Graduate Department of Ecology and Evolutionary Biology University of Toronto 2019 Abstract Theory has proposed that a trade-off causing negative covariance in competitive and colonization abilities (the competition-colonization trade-off) is an important mechanism enabling coexistence of species across local and regional scales. However, empirical tests of this trade-off are limited, especially in naturalistic conditions with active dispersers; organisms capable of making their own movement decisions. I tested the competition-colonization trade-off in two co-occurring flight-capable semi-aquatic insect backswimmers (Notonecta undulata and Notonecta irrorata). Using field mesocosm experiments and laboratory experiments, I measured components of dispersal and competition to determine if and how the competition-colonization trade-off enables coexistence in this system. This thesis reveals that backswimmer species exhibited clear differences in dispersal behaviour and yet competition proved to be multi-faceted and context-dependent. This work suggests that in active dispersers, there is a great deal of complexity in competition and dispersal. Future studies of the competition-colonization trade-off in naturalistic communities should incorporate these complexities. ii Acknowledgments Thank you to my supervisor, Dr. Shannon McCauley, for her support, encouragement, and guidance throughout my studies.

  • Loss of Genetic Diversity in the North American Mayfly Ephemerella
    Freshwater Biology (2011) doi:10.1111/j.1365-2427.2010.02566.x APPLIED ISSUES Loss of genetic diversity in the North American mayfly Ephemerella invaria associated with deforestation of headwater streams LAURIE C. ALEXANDER*, DAVID J. HAWTHORNE†, MARGARET A. PALMER† AND WILLIAM O. LAMP† *U.S. Environmental Protection Agency, Washington, DC, U.S.A. †Department of Entomology, University of Maryland, College Park, Maryland, U.S.A. SUMMARY 1. Terrestrial dispersal by aquatic insects increases population connectivity in some stream species by allowing individuals to move outside the structure of the stream network. In addition, individual survival and reproductive success (as well as dispersal) are tightly linked to the quality of the terrestrial habitat. 2. In historically forested catchments, deforestation and altered land use have the potential to interfere with mayfly dispersal or mating behaviours by degrading the quality of the terrestrial matrix among headwater streams. We hypothesised that loss of tree cover in first-order catchments would be associated with an increase in population substructure and a decrease in genetic diversity of mayfly populations. 3. To test this hypothesis, we investigated spatial patterns of genetic variation in the common mayfly Ephemerella invaria across a gradient of deforestation in the central piedmont region of eastern United States. Intraspecific genetic diversity and population substructure were estimated from data obtained using fluorescent amplified fragment length polymorphism (AFLP) markers. 4. We found that mayfly populations had low population substructure within headwater stream networks and that genetic diversity was strongly negatively correlated with mean deforestation of the first-order catchments. The large-scale pattern of population substructure followed a pattern of isolation by distance (IBD) in which genetic differentiation increases with geographical distance, but assignment tests placed a few individuals into populations 300 km away from the collection site.

  • Arthropods of Elm Fork Preserve
    Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux.

A strict consensus tree calculated (439 steps, consistency index ¼ 0.45, retention index ¼ 0.75) from the two most-parsimonious cladograms indicated that the monophyly of the family and subfamilies is supported, with the exception of Eubriinae, which is paraphyletic when including Afroeubria. Here a new subfamily, Afroeubriinae (subfam.n.), is formally estab- lished for Afroeubria. The analysis also indicated that the ‘streamlined’ larva is a derived adaptive radiation. Here, suprageneric taxonomy and the evolution of some significant characters are discussed. Keys are provided to the subfamilies and genera of Psephenidae considering larvae, adults and pupae. Introduction type specimens and the association of adults and immature stages by rearing, five new genera were proposed for Ori- Psephenidae, the ‘water penny’ beetles, are characterized by ental taxa and a well-resolved phylogenetic tree was ob- the peculiar larval body shape (Figs 4–7).
