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. -
The Nestling Diet of Svalbard Snow Buntings Identified by DNA Metabarcoding
Faculty of Biosciences, Fisheries and Economics, Department of Arctic and Marine Biology The nestling diet of Svalbard snow buntings identified by DNA metabarcoding — Christian Stolz BIO-3950 Master thesis in Biology, Northern Populations and Ecosystems, May 2019 Faculty of Biosciences, Fisheries and Economics, Department of Arctic and Marine Biology The nestling diet of Svalbard snow buntings identified by DNA metabarcoding Christian Stolz, UiT The Arctic University of Norway, Tromsø, Norway and The University Centre in Svalbard (UNIS), Longyearbyen, Norway BIO-3950 Master Thesis in Biology, Northern Populations and Ecosystems, May 2018 Supervisors: Frode Fossøy, Norwegian Institute for Nature Research (NINA), Trondheim, Norway Øystein Varpe, The University Centre in Svalbard (UNIS), Longyearbyen, Norway Rolf Anker Ims, UiT The Arctic University of Norway, Tromsø, Norway i Abstract Tundra arthropods have considerable ecological importance as a food source for several bird species that are reproducing in the Arctic. The actual arthropod taxa comprising the chick diet are however rarely known, complicating assessments of ecological interactions. In this study, I identified the nestling diet of Svalbard snow bunting (Plectrophenax nivalis) for the first time. Faecal samples of snow bunting chicks were collected in Adventdalen, Svalbard in the breeding season 2018 and analysed via DNA metabarcoding. Simultaneously, the availability of prey arthropods was measured via pitfall trapping. The occurrence of 32 identified prey taxa in the nestling diet changed according to varying abundances and emergence patterns within the tun- dra arthropod community: Snow buntings provisioned their offspring mainly with the most abundant prey items which were in the early season different Chironomidae (Diptera) taxa and Scathophaga furcata (Diptera: Scathophagidae), followed by Spilogona dorsata (Diptera: Mus- cidae). -

Sambia Succinica, a Crown Group Tenthredinid from Eocene Baltic Amber (Hymenoptera: Tenthredinidae)
Insect Systematics & Evolution 43 (2012) 271–281 brill.com/ise Sambia succinica, a crown group tenthredinid from Eocene Baltic amber (Hymenoptera: Tenthredinidae) Lars Vilhelmsena,* and Michael S. Engelb aNatural History Museum of Denmark, University of Copenhagen, Universitetsparken 15, DK-2100 Copenhagen, Denmark bDivision of Entomology (Paleoentomology), Natural History Museum and Department of Ecology & Evolutionary Biology, 1501 Crestline Drive, Suite 140, University of Kansas, Lawrence KS 66045, USA *Corresponding author, e-mail: [email protected] Published 17 December 2012 Abstract Sambia succinica gen. et sp.n. from Eocene Baltic amber is described and illustrated. It is apparently the first amber fossil that can be definitively assigned to Tenthredininae. It displays two diagnostic forewing characters for this subfamily: having a bend distally in vein R and the junctions of veins M and Rs + M with vein R being some distance from each other. The variance and possible transitions between the anal vein configurations among the genera in Tenthredininae is briefly discussed. Keywords amber inclusion, sawfly, Tertiary, Eocene, taxonomy Introduction Tenthredinidae is the largest family of non-apocritan Hymenoptera by far, comprising more than 5500 described species (Huber 2009; Taeger & Blank 2010). Together with five other families they comprise the Tenthredinoidea or true sawflies. The larvae of the members of the superfamily are all herbivores and most are external feeders on green parts of angiosperms; however, other host plants and feeding modes (e.g., leafrolling, leafmining, or galling in leaves, buds and shoots; see Nyman et al. 1998, 2000) do occur. Recent comprehensive treatments of the phylogeny of the basal hymenopteran lineages, while providing strong support for the Tenthredinoidea, have consistently failed to retrieve the Tenthredinidae as monophyletic (Vilhelmsen 2001; Schulmeister 2003; Ronquist et al. -

R .China. 1Corresponding author. E-mail: [email protected] 2E-mail:[email protected] Abstract Megadineura leucotarsis Wei, a new species of Nematinae (Hymenoptera, Tenthredinidae) from China is described. The genus Megadineura Malaise, 1931 is redescribed and a key to known species is provided. The difference between Mega- dineura and Mesoneura Hartig, 1837, Renonerva Wei & Nie, 1998, Katsujia Togashi, 1964 is also discussed briefly. The type specimens of the new species are deposited in the Insect Collection of Central South University of Forestry and Technology, China. Key words: Hymenoptera, Tenthredinidae, Nematinae, Megadineura, new species, China Introduction The genus Megadineura was erected by Malaise in 1931 for Dineura grandis André, 1882 from E. Siberia and Japan (Malaise 1931). Megadineura is so rare that only a few publications have referred to it in the past 75 years. The genus can be easily recognized by the large and elongated body, the presence of vein 1r in the forewing (unusual for the subfamily Nematinae), the broad frontal wall, large claw, thick and black antenna with 2 or 3 apical segments white, rugose mesepisternum and the simple sheath. Benson (1963) described a second species of the genus, M. himalayana, from Kashmir. -

Key words: Hymenoptera; Symphyta; Tenthredinidae; Pristiphora; Pachynematus; Pontania; Euura; Japan; Korea; new species. Seven new species of Nematinae (Tenthredinidae) from Japan and Korea are described: Pachynematus hirowatari spec. nov, P. hayachinensis spec. nov., Pristiphora nigrocoreana spec. nov, P. issikii spec. nov., P. shinoharai spec. nov, Pontania nipponica spec. nov. and Euura soboensis spec. nov. Pristiphora punctifrons (Thomson, 1871) is new record for Japan. Introduction Matsumura (1912) was the fi rst to study intensively the sawfl y fauna of Japan. However, the Nematinae sawfl ies are a group that has been neglected and its species are still poorly known. As a comparison, 116 Nematinae species occur in the post-Trianon Hungary (93,000 mi2) (Haris, 2001), yet only 94 species are recorded from Japan (377,835 mi2). In this paper, I add eight species to the Japanese and Korean fauna, seven of which are new and one is new record. A revision of the Nematinae of Japan and the Far East will be published in a separate paper. The material studied is mainly in the Takeuchi collection deposited in the Univer- sity of Osaka Prefecture; one species is described from the collection of the National Museum of Natural History, Washington D.C. -
Havelland 2030
Zukunft Havelland 30.07.13 1 Liebe Havelländerinnen und Havelländer, die SPD Havelland hat fast 2 Jahre über die „Zukunft des Havellandes“ diskutiert. Wir haben dies in Arbeitsgruppen getan, in öffentlichen Veran- staltungen zur Bildungspolitik, zur „Zukunft des ländlichen Raumes und zu „Arbeit und Wirtschaft, im Internet und in unseren Ortsvereinen. Ent- standen ist das Ihnen vorliegende Programm „Zukunft Havelland“, das wir Sozialdemokratinnen und Sozialdemokraten auf unserem Parteitag in Paaren/Glien am 15. Juni beschlossen haben. Die SPD Havelland gestaltet seit 1990 aktiv das Havelland, seit Grün- dung des Kreises Havelland aus den Kreisen Nauen und Rathenow En- de 1993 stellen wir mit Burkhard Schröder den Landrat. Wir haben viel erreicht. Aber wir kennen auch die Herausforderungen: die unterschied- liche Bevölkerungsentwicklung im Osten und im Westen unseres Land- kreises, eine sichere und umweltfreundliche Energieversorgung, die De- ckung des Fachkräftebedarfs, die Sicherung von Mobilität, Chancen für unsere Kinder und eine gute gesundheitliche und soziale Infrastruktur. Wir haben uns vorgestellt, wie sieht unser Havelland im Jahr 2030 aus oder besser, wie sollte es aussehen. Und wie bewältigen wir die Heraus- forderungen. Wir wollten aber keine Luftschlösser bauen, sondern von der Realität ausgehen, wie wir sie heute erleben. Unser Programm ist in 9 Kapitel unterteilt, ein allgemeines und 8 Hand- lungsfelder. Ich hoffe, Sie finden dort die Sie besonders betreffenden oder interessierenden Themen. Wir sind weiterhin auf Ihre Reaktionen gespannt. Ihr Martin Gorholt 2 Inhaltsverzeichnis 1.
