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.

  • Open Letter of the National Academy of Sciences of Ukraine
    We would highly appreciate if you correctly attribute to Ukraine the publications produced by scientists based in Sevastopol, Simferopol, Kerch, Yalta, Nikita, Feodosia, Nauchny, Simeiz, Yevpatoria, Saki, and other cities and towns of the Crimean region, Donetsk, and Luhansk, in particular the Crimean Laser Observatory of the Main Astronomical Observatory, the Marine Institute of Hydrophysics, the Crimean Nature Reserve, the Karadag Nature Reserve, the O.O.Kovalevsky Institute of Biology of the Southern Seas, the Donetsk O.O.Galkin Institute of Physics and Engineering, and others. We insist on appropriate attributions of Crimean and Donbas research institutions to Ukraine in any publications, especially in international journals. In those cases when items with inappropriate country affiliation have been already published due to neglect or for some other reason, we request the soonest possible publication of corrigenda or editorial notes, explaining the temporary occupied status of the Crimea and the Donbas. In those cases when Crimean or Donbas authors, for fear of repressions, provide for communication reasons their current addresses as Russia or Russian Federation, the editorial disclaimer has to be made indicating the real status of Crimea and Donbas as a constituent and integral part of Ukraine, with proper reference to the relevant international documents adopted by the UN and/or other bodies. An example of such a disclaimer could be as follows: “The author(s) from the Crimea / Donbas of the article(s) appearing in this Journal is/are solely responsible for the indication of his/her/their actual postal address(es) and country affiliation(s). However, the Journal states that the country affiliation(s) indicated in the article is/are improper.

  • Arachnids (Excluding Acarina and Pseudoscorpionida) of the Wichita Mountains Wildlife Refuge, Oklahoma
    OCCASIONAL PAPERS THE MUSEUM TEXAS TECH UNIVERSITY NUMBER 67 5 SEPTEMBER 1980 ARACHNIDS (EXCLUDING ACARINA AND PSEUDOSCORPIONIDA) OF THE WICHITA MOUNTAINS WILDLIFE REFUGE, OKLAHOMA JAMES C. COKENDOLPHER AND FRANK D. BRYCE The Wichita Mountains are located in eastern Greer, southern Kiowa, and northwestern Comanche counties in Oklahoma. Since their formation more than 300 million years ago, these rugged mountains have been fragmented and weathered, until today the highest peak (Mount Pinchot) stands only 756 meters above sea level (Tyler, 1977). The mountains are composed predominantly of granite and gabbro. Forests of oak, elm, and walnut border most waterways, while at elevations from 153 to 427 meters prair­ ies are the predominant vegetation type. A more detailed sum­ mary of the climatic and biotic features of the Wichitas has been presented by Blair and Hubbell (1938). A large tract of land in the eastern range of the Wichita Moun­ tains (now northeastern Comanche County) was set aside as the Wichita National Forest by President McKinley during 1901. In 1905, President Theodore Roosevelt created a game preserve on those lands managed by the Forest Service. Since 1935, this pre­ serve has been known as the Wichita Mountains Wildlife Refuge. Numerous papers on Oklahoma spiders have been published (Bailey and Chada, 1968; Bailey et al., 1968; Banks et al, 1932; Branson, 1958, 1959, 1966, 1968; Branson and Drew, 1972; Gro- thaus, 1968; Harrel, 1962, 1965; Horner, 1975; Rogers and Horner, 1977), but only a single, comprehensive work (Banks et al., 1932) exists covering all arachnid orders in the state.

    THE BIOLOGY AND POPULATION ECOLOGY OF flACROSTELES SEXNOTATUS (FALLEN) (CICADELLIDAE, HEnIPTERA) by Miriam Becker, M.Sc. (Brazil) December, 1974 A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Imperial College Imperial College of Science and Technology, Silwood Park, Ascot, Berkshire. 2 ABSTRACT Studies in the laboratory and under field conditions were made on the biology and population ecology of Macrosteles sexnotatus (Fall6n) (Cicadellidae, Hemiptera). Laboratory studies on the biology were carried out under a set of constant temperature conditions. The rela- tionship between temperature and rates of egg and nymphal development are presented and discussed. Effects of tempera- ture on fecundity and longevity were also studied, and choice of oviposition sites under laboratory and field conditions were investigated. Studies were carried out to induce hatching of diapausing eggs and also to induce diapause in the eggs. The internal reproductive organs of males and females are described and illustrated. Illustrated descrip- tions are also given of the five nymphal stages and sexes are distinguished from third instar onwards. Descriptions and illustrations are given of a short winged form which occurred in the laboratory cultures. Population studies_of M. sexnotatus in an catfield • were carried out from 1972 to 1974. Adults and nymphs were sampled regularly with a D-vac suction sampler and occa- sionally with a sweep net. Weekly population estimates were made from June to late September for 1973 and 1974 and for August and September of 1972. Population budgets are presented and causes of mortality are discussed. Losses caused by parasitism in the nymphal and adult stages are 3 shown to be smaller than those within the egg stage.

  • Distribution of Spiders in Coastal Grey Dunes

The knowledge of dispersal evolution, motivation, its effect on metapopulation dynamics and species distribution at multiple scales is poorly understood and many questions remain unsolved or require empirical verification. In this thesis we contribute to the knowledge of dispersal, by studying both ecological and evolutionary aspects of spider dispersal in fragmented grey dunes. Studies were performed at the individual, population and assemblage level and indicate that behavioural traits narrowly linked to dispersal, con- siderably show [adaptive] variation in function of habitat quality and geometry. Dispersal also determines spider distribution patterns and metapopulation dynamics. Consequently, our results stress the need to integrate knowledge on behavioural ecology within the study of ecological landscapes. / Promotor: Prof. Dr. Eckhart Kuijken [Ghent University & Institute of Nature Dries Bonte Conservation] Co-promotor: Prf.

F. R. Mahmoud1 and * Nadia A. Abdel lattif2 1- Department of Plant Protection, Faculty of Agriculture, Fayoum Univ. Egypt 2- Plant Protection research Institute , A.R.C. Ministry of Agriculture, Dokki, Giza, Egypt ABSTRACT Laboratory studies of Thanatus formicinus (Clerck) with feeding on Psammotermes hybostoma termites proved that the developmental period of spiderlings varied with sex and between siblings. Females lived longer periods and consumed larger number of prey compared with males. The incubation period of eggs ranged between 9-15 days. The eggs hatchability recorded 73.4 % of the total deposited eggs. Each ootheca contained 25-40 eggs with a mean of 31.6 eggs. Mean number of eggs /female was ranging 189-253 eggs. Spiderlings females consumed a total prey average of 383.6 prey and 349.9 prey for spiderlings males. The mean number of prey consumed by females adult was 936.9 prey / female and 715.4 prey for males adult. Food consumption throughout the period of life span was 1320.5 prey for females and 1065.3 prey for males.

Zamani, E-mail: [email protected] Received: 08. February 2015 / Accepted: 11. May 2015 / Available online: 01. June 2016 / Printed: June 2016 Abstract. In a survey investigating the spider fauna of Dargaz and Kalat counties in Razavi Khorasan Province of Iran, 13 families and 21 species were recognized, of which three are new to Iran: Minosia simeonica Levy, 1995, Nomisia negebensis Levy, 1995 and Thanatus atratus Simon, 1875. Also, genus Minosia Dalmas, 1921 is recorded for the first time in Iran. Data on collection localities and distribution of each species, as well as diagnostic morphological characters and figures for the newly recorded taxa are provided. Key words: new records, Thanatus, Minosia, Nomisia, Iran. Introduction Spiders (Araneae), with over 45000 recognized species in the world (World Spider Catalog 2015). Reviewing the literature, Zamani et al. (2015a) gave a checklist of spiders of Iran with about 540 species. Considering the geographic position of the country as a land bridge joining the Palaearctic, Afro- tropical and Oriental zones, and its diverse climate condi- tions and the known spider fauna of adjacent countries, it seems that this number must be much higher than known at present.
