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.

Leppo4 Tetra Tech, Inc., 400 Red Brook Blvd., Suite 200, Owings Mills, Maryland 21117-5159 USA Abstract. Taxonomic identifications are central to biological assessment; thus, documenting and reporting uncertainty associated with identifications is critical. The presumption that comparable results would be obtained, regardless of which or how many taxonomists were used to identify samples, lies at the core of any assessment. As part of a national survey of streams, 741 benthic macroinvertebrate samples were collected throughout the eastern USA, subsampled in laboratories to ;500 organisms/sample, and sent to taxonomists for identification and enumeration. Primary identifications were done by 25 taxonomists in 8 laboratories. For each laboratory, ;10% of the samples were randomly selected for quality control (QC) reidentification and sent to an independent taxonomist in a separate laboratory (total n ¼ 74), and the 2 sets of results were compared directly. The results of the sample-based comparisons were summarized as % taxonomic disagreement (PTD) and % difference in enumeration (PDE). Across the set of QC samples, mean values of PTD and PDE were ;21 and 2.6%, respectively.

    ~ ~ WISCONSIN DEPARTMENT OF NATURAL RESOURCES A Survey of Rare and Endangered Mayflies of Selected RESEARCH Rivers of Wisconsin by Richard A. Lillie REPORT110 Bureau of Research, Monona December 1995 ~ Abstract The mayfly fauna of 25 rivers and streams in Wisconsin were surveyed during 1991-93 to document the temporal and spatial occurrence patterns of two state endangered mayflies, Acantha­ metropus pecatonica and Anepeorus simplex. Both species are candidates under review for addition to the federal List of Endang­ ered and Threatened Wildlife. Based on previous records of occur­ rence in Wisconsin, sampling was conducted during the period May-July using a combination of sampling methods, including dredges, air-lift pumps, kick-nets, and hand-picking of substrates. No specimens of Anepeorus simplex were collected. Three specimens (nymphs or larvae) of Acanthametropus pecatonica were found in the Black River, one nymph was collected from the lower Wisconsin River, and a partial exuviae was collected from the Chippewa River. Homoeoneuria ammophila was recorded from Wisconsin waters for the first time from the Black River and Sugar River. New site distribution records for the following Wiscon­ sin special concern species include: Macdunnoa persimplex, Metretopus borealis, Paracloeodes minutus, Parameletus chelifer, Pentagenia vittigera, Cercobrachys sp., and Pseudiron centra/is. Collection of many of the aforementioned species from large rivers appears to be dependent upon sampling sand-bottomed substrates at frequent intervals, as several species were relatively abundant during only very short time spans. Most species were associated with sand substrates in water < 2 m deep. Acantha­ metropus pecatonica and Anepeorus simplex should continue to be listed as endangered for state purposes and receive a biological rarity ranking of critically imperiled (S1 ranking), and both species should be considered as candidates proposed for listing as endangered or threatened as defined by the Endangered Species Act.

    insects Article The Imaginal Characters of Neoephemera projecta Showing Its Plesiomorphic Position and a New Genus Status in the Family (Ephemeroptera: Neoephemeridae) Zhenxing Ma and Changfa Zhou * College of Life Sciences, Nanjing Normal University, Nanjing 210023, China; [email protected] * Correspondence: [email protected]; Tel.: +86-139-5174-7595 Simple Summary: The phylogenetically problematic Neoephemeridae is a small family of the order Ephemeroptera, including four genera reported previously. They are genera Neoephemera (in Nearctic region), Ochernova (Central Asia), Leucorhoenanthus (West Palearctic) and Potamanthellus (East Palearctic and Oriental regions), which were geographically isolated until the Neoephemera projecta Zhou and Zheng, a species reported in 2001 from Southwestern China, connected them together. In this work, the imaginal stage and biology of Neoephemera projecta are first observed and described. Furthermore, a series of autapomorphies and plesiomorphies of it are recognized and discussed. Morphologically and biologically, this species is significantly different from other genera and deserves a new plesiomorphic position in the Family Neoephemeridae. Therefore, a new genus Pulchephemera gen. n. is established to reflect its primitive position and intermediate characters of two clades of the family. In addition, some shared characters of this new genus and the family Ephemeridae provide a new perspective or possibility on the phylogeny of Neoephemeridae within Citation: Ma, Z.; Zhou, C.

    Life History and Production of Mayflies, Stoneflies, and Caddisflies (Ephemeroptera, Plecoptera, and Trichoptera) in a Spring-Fe

    Color profile: Generic CMYK printer profile Composite Default screen 1083 Life history and production of mayflies, stoneflies, and caddisflies (Ephemeroptera, Plecoptera, and Trichoptera) in a spring-fed stream in Prince Edward Island, Canada: evidence for population asynchrony in spring habitats? Michelle Dobrin and Donna J. Giberson Abstract: We examined the life history and production of the Ephemeroptera, Plecoptera, and Trichoptera (EPT) commu- nity along a 500-m stretch of a hydrologically stable cold springbrook in Prince Edward Island during 1997 and 1998. Six mayfly species (Ephemeroptera), 6 stonefly species (Plecoptera), and 11 caddisfly species (Trichoptera) were collected from benthic and emergence samples from five sites in Balsam Hollow Brook. Eleven species were abundant enough for life-history and production analysis: Baetis tricaudatus, Cinygmula subaequalis, Epeorus (Iron) fragilis,andEpeorus (Iron) pleuralis (Ephemeroptera), Paracapnia angulata, Sweltsa naica, Leuctra ferruginea, Amphinemura nigritta,and Nemoura trispinosa (Plecoptera), and Parapsyche apicalis and Rhyacophila brunnea (Trichoptera). Life-cycle timing of EPT taxa in Balsam Hollow Brook was generally similar to other literature reports, but several species showed extended emergence periods when compared with other studies, suggesting a reduction in synchronization of life-cycle timing, pos- sibly as a result of the thermal patterns in the stream. Total EPT secondary production (June 1997 to May 1998) was 2.74–2.80 g·m–2·year–1 dry mass (size-frequency method). Mayflies were dominant, with a production rate of 2.2 g·m–2·year–1 dry mass, followed by caddisflies at 0.41 g·m–2·year–1 dry mass, and stoneflies at 0.19 g·m–2·year–1 dry mass.
