ARTHROPOD COMMUNITIES and PASSERINE DIET: EFFECTS of SHRUB EXPANSION in WESTERN ALASKA by Molly Tankersley Mcdermott, B.A./B.S
Arthropod communities and passerine diet: effects of shrub expansion in Western Alaska Item Type Thesis Authors McDermott, Molly Tankersley Download date 26/09/2021 06:13:39 Link to Item http://hdl.handle.net/11122/7893 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. -
Wild Species 2010 the GENERAL STATUS of SPECIES in CANADA
Wild Species 2010 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council (CESCC). 2011. Wild Species 2010: The General Status of Species in Canada. National General Status Working Group: 302 pp. Available in French under title: Espèces sauvages 2010: La situation générale des espèces au Canada. ii Abstract Wild Species 2010 is the third report of the series after 2000 and 2005. The aim of the Wild Species series is to provide an overview on which species occur in Canada, in which provinces, territories or ocean regions they occur, and what is their status. Each species assessed in this report received a rank among the following categories: Extinct (0.2), Extirpated (0.1), At Risk (1), May Be At Risk (2), Sensitive (3), Secure (4), Undetermined (5), Not Assessed (6), Exotic (7) or Accidental (8). In the 2010 report, 11 950 species were assessed. Many taxonomic groups that were first assessed in the previous Wild Species reports were reassessed, such as vascular plants, freshwater mussels, odonates, butterflies, crayfishes, amphibians, reptiles, birds and mammals. Other taxonomic groups are assessed for the first time in the Wild Species 2010 report, namely lichens, mosses, spiders, predaceous diving beetles, ground beetles (including the reassessment of tiger beetles), lady beetles, bumblebees, black flies, horse flies, mosquitoes, and some selected macromoths. The overall results of this report show that the majority of Canada’s wild species are ranked Secure. -

Sand pit for Biodiversity at Cep II quarry Researcher: Klára Řehounková Research group: Petr Bogusch, David Boukal, Milan Boukal, Lukáš Čížek, František Grycz, Petr Hesoun, Kamila Lencová, Anna Lepšová, Jan Máca, Pavel Marhoul, Klára Řehounková, Jiří Řehounek, Lenka Schmidtmayerová, Robert Tropek Březen – září 2012 Abstract We compared the effect of restoration status (technical reclamation, spontaneous succession, disturbed succession) on the communities of vascular plants and assemblages of arthropods in CEP II sand pit (T řebo ňsko region, SW part of the Czech Republic) to evaluate their biodiversity and conservation potential. We also studied the experimental restoration of psammophytic grasslands to compare the impact of two near-natural restoration methods (spontaneous and assisted succession) to establishment of target species. The sand pit comprises stages of 2 to 30 years since site abandonment with moisture gradient from wet to dry habitats. In all studied groups, i.e. vascular pants and arthropods, open spontaneously revegetated sites continuously disturbed by intensive recreation activities hosted the largest proportion of target and endangered species which occurred less in the more closed spontaneously revegetated sites and which were nearly absent in technically reclaimed sites. Out results provide clear evidence that the mosaics of spontaneously established forests habitats and open sand habitats are the most valuable stands from the conservation point of view. It has been documented that no expensive technical reclamations are needed to restore post-mining sites which can serve as secondary habitats for many endangered and declining species. The experimental restoration of rare and endangered plant communities seems to be efficient and promising method for a future large-scale restoration projects in abandoned sand pits. -
Bugs & Beasties of the Western Rhodopes
Bugs and Beasties of the Western Rhodopes (a photoguide to some lesser-known species) by Chris Gibson and Judith Poyser [email protected] Yagodina At Honeyguide, we aim to help you experience the full range of wildlife in the places we visit. Generally we start with birds, flowers and butterflies, but we don’t ignore 'other invertebrates'. In the western Rhodopes they are just so abundant and diverse that they are one of the abiding features of the area. While simply experiencing this diversity is sufficient for some, as naturalists many of us want to know more, and in particular to be able to give names to what we see. Therein lies the problem: especially in eastern Europe, there are few books covering the invertebrates in any comprehensive way. Hence this photoguide – while in no way can this be considered an ‘eastern Chinery’, it at least provides a taster of the rich invertebrate fauna you may encounter, based on a couple of Honeyguide holidays we have led in the western Rhodopes during June. We stayed most of the time in a tight area around Yagodina, and almost anything we saw could reasonably be expected to be seen almost anywhere around there in the right habitat. Most of the photos were taken in 2014, with a few additional ones from 2012. While these creatures have found their way into the lists of the holiday reports, relatively few have been accompanied by photos. We have attempted to name the species depicted, using the available books and the vast resources of the internet, but in many cases it has not been possible to be definitive and the identifications should be treated as a ‘best fit’. -
