ARTHROPOD COMMUNITIES and PASSERINE DIET: EFFECTS of SHRUB EXPANSION in WESTERN ALASKA by Molly Tankersley Mcdermott, B.A./B.S

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. -

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. An approach to automatic hoverfly species discrimination based on detection and extraction of vein junctions in wing venation patterns of insects is presented in the paper. The dataset used in our experiments consists of high resolution microscopic wing images of several hoverfly species collected over a relatively long period of time at different geographic locations. Junctions are detected using the combination of the well known HOG (histograms of oriented gradients) and the robust version of recently proposed CLBP (complete local binary pattern). These features are used to train an SVM classifier to detect junctions in wing images. -

Munis Entomology & Zoology, 5, suppl.: 900-903] ABSTRACT: Baccha elongata (Fabricius), 1775 is recorded for the first time from Iran. Three specimens were collected from Aynali forests. The related key, diagnosis characters and photos are presented. KEY WORDS: Diptera, Syrphidae, New record, Fauna, Aynali forests, Iran. The genus Baccha was described by Fabricius (1805) with Syrphus elongatus Fabricius, 1775 designated as the type species (Peck, 1988). This genus belonged to Syrphinae subfamily and Bacchini tribe. All species of the subfamily Syrphinae with an entirely blak scutellum are likely to belong to this tribe of four genera. The only exceptions are Paragus which is very distinctive, and some specimens of Melangyna arctica wich is included in the next trible, the Syrphini. There is generally a pattern on the abdomen consisting of pairs of colored spots of grey, yellow or orange (Stubbs and Fulk, 2002). They are, however, easily overlooked because of their frequent habit of hovering low down among vegetation or, even if above vegetation, they are inconspicuous in dappled shade. Baccha is a small genus including two species in palearctic region, B. -

Hoverfly Newsletter 36
HOVERFLY NUMBER 36 NEWSLETTER AUGUST 2003 ISSN 1358-5029 This edition is being produced in the wake of the second international symposium which was held in Alicante in June. Alan Stubbs has commented below that Spain was, as expected, too dry in mid-June for many hoverflies to be found. It seems to me that the same comment is true for Britain for much of the present season; although I have had a few productive days this year, on the majority of occasions when I have been in the field hoverfly numbers have proved to be sparse as a result of the hot and very dry conditions. The growth of interest on the subject however continues unabated, as anyone who subscribes to the UK hoverfly email exchange group will testify.

Hoverfly Newsletter 34
HOVERFLY NUMBER 34 NEWSLETTER AUGUST 2002 ISSN 1358-5029 Long-standing readers of this newsletter may wonder what has happened to the lists of references to recent hoverfly literature that used to appear regularly in these pages. Graham Rotheray compiled these when he was editor and for some time afterwards, and more recently they have been provided by Kenn Watt. For some time Kenn trawled for someone else to take over this task from him, but nobody volunteered. Kenn continued to produce the lists, but now no longer has access to the source that provided him with the references. I therefore now make a plea for someone else to agree to take over this role, ideally producing a list of recent literature for each edition of this newsletter (i.e. twice per year), or if that is not possible, for each alternate edition. Failing a reply to this plea, has anyone any suggestions for a reliable source of references to which I could get access in order to compile the list myself?

Here, we monitored for 2 years (2011–2012) the response of herbivores and natural enemies to MeSA lures (PredaLure) by using sticky and pitfall traps in cranberry bogs. In addition, European corn borer, Ostrinia nubilalis, egg masses were used to determine whether natural enemy attraction to MeSA leads to higher predation. In both years, MeSA increased adult hoverfly captures on sticky traps and augmented predation of O. nubilalis eggs. However, MeSA also attracted more phytophagous thrips and, in 2012, more plant bugs (Miridae) to sticky traps. Furthermore, we used surveillance cameras to record the identity of natural enemies attracted to MeSA and measure their predation rate. -
