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. -

Biodiversity Data Journal 9: e69924. https://doi.org/10.3897/BDJ.9.e69924 Abstract Background Long-term monitoring of invertebrate communities is needed to understand the impact of key biodiversity erosion drivers (e.g. habitat fragmentation and degradation, invasive species, pollution, climatic changes) on the biodiversity of these high diverse organisms. The data we present are part of the long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) that started in 2012, aiming to understand the impact of biodiversity erosion drivers on Azorean native forests (Azores, Macaronesia, Portugal). In this contribution, the design of the project, its objectives and the first available data for the spider fauna of two Islands (Pico and Terceira) are described. -

Check-List of Polish Spiders (Araneae, Except Salticidae) File:///D:/Internet/Polen/Polen Spinnenliste 2004.Htm
Check-list of Polish spiders (Araneae, except Salticidae) file:///D:/Internet/Polen/Polen Spinnenliste 2004.htm Check-list of Polish spiders (Araneae, except Salticidae) 1. November, 2004 by Wojciech STARĘGA Instytut Biologii, Katedra Zoologii, Akademia Podlaska, Siedlce [email protected] The present list is a compilation and continuation of the earlier check-lists of Polish spiders (PRÓSZYŃSKI & STARĘGA 1971, 1997, 2003, STARĘGA 1983, PROSZYNSKI & STAREGA 2002]. It will be currently updated, according to the progress of cognition of the country's spider fauna. I give also a list of the most important faunistic and other publications after 1971 which add any species new to the Polish fauna (or cross out some of them). The nomenclatural changes were regarded as far as possible to unify the names used in Polish arachnological literature with those in foreign check-lists and catalogues (e.g. PLATEN & al. 1995, commented by BLICK 1998), NENTWIG et. at. 2003, TANASEVITCH 2004, and first of all, with the latest version (5.0) of the "Spider Catalog" by PLATNICK (2004). The species, which occurrence in Poland is certain, have serial numbers, some exceptions which need confirmation or re-examination are marked with "X" sign instead of a number; doubtful species were not listed, though named in earlier papers (pre-1971). Species described from Poland (or with Polish localities mentioned in their original descriptions) are marked with „☼” sign. Species not "officially" known (i.e. published) from Poland but whose occurrence is already confirmed have remark „(fide ... [the name of its finder])". Some nomenclatorical remarks are given in square brackets. The species protected by law are marked with an asterisk (*), threatened ones - with symbols (in italics) used in the newest "Red list of threatened species in Poland" (STARĘGA & al. -

I am also hugely endebted to Dr Keith Spriggs who became my mentor in the field of RNA and without whom my understanding of the field would have been but a fraction of what it is now. Particular thanks go to Professor John Brookfield, an expert in the field of biological statistics and data retrieval. Likewise with Dr Susan Liddell for her proteomics assistance, a truly remarkable individual on par with Professor Brookfield in being able to simplify even the most complex techniques and analyses. Finally, I would really like to thank Janet Beccaloni for her time and resources at the Natural History Museum, London, permitting me access to the collections therein; ten years on and still a delight. Finally, amongst the greats, Alexander ‘Sasha’ Kondrashov… a true inspiration. I would also like to express my gratitude to those who, although may not have directly contributed, should not be forgotten due to their continued assistance and considerate nature: Dr Chris Wade (five straight hours of help was not uncommon!), Sue Buxton (direct to my bench creepy crawlies), Sheila Keeble (ventures and cleans where others dare not), Alice Young (read/checked my thesis and overcame her arachnophobia!) and all those in the Centre for Biomolecular Sciences. -

Behavioral Ecology Symposium ’96: Cushing 165 MYRMECOMORPHY AND MYRMECOPHILY IN SPIDERS: A REVIEW PAULA E. CUSHING The College of Wooster Biology Department 931 College Street Wooster, Ohio 44691 ABSTRACT Myrmecomorphs are arthropods that have evolved a morphological resemblance to ants. Myrmecophiles are arthropods that live in or near ant nests and are considered true symbionts. The literature and natural history information about spider myrme- comorphs and myrmecophiles are reviewed. Myrmecomorphy in spiders is generally considered a type of Batesian mimicry in which spiders are gaining protection from predators through their resemblance to aggressive or unpalatable ants. Selection pressure from spider predators and eggsac parasites may trigger greater integration into ant colonies among myrmecophilic spiders. Key Words: Araneae, symbiont, ant-mimicry, ant-associates RESUMEN Los mirmecomorfos son artrópodos que han evolucionado desarrollando una seme- janza morfológica a las hormigas. Los Myrmecófilos son artrópodos que viven dentro o cerca de nidos de hormigas y se consideran verdaderos simbiontes. Ha sido evaluado la literatura e información de historia natural acerca de las arañas mirmecomorfas y mirmecófilas . El myrmecomorfismo en las arañas es generalmente considerado un tipo de mimetismo Batesiano en el cual las arañas están protegiéndose de sus depre- dadores a través de su semejanza con hormigas agresivas o no apetecibles. La presión de selección de los depredadores de arañas y de parásitos de su saco ovopositor pueden inducir una mayor integración de las arañas mirmecófílas hacia las colonias de hor- migas. Myrmecomorphs and myrmecophiles are arthropods that have evolved some level of association with ants. Myrmecomorphs were originally referred to as myrmecoids by Donisthorpe (1927) and are defined as arthropods that mimic ants morphologically and/or behaviorally. -
MAHS Care Sheet Master List *By Eric Roscoe Care Sheets Are Often An
MAHS Care Sheet Master List *By Eric Roscoe Care sheets are often an excellent starting point for learning more about the biology and husbandry of a given species, including their housing/enclosure requirements, temperament and handling, diet , and other aspects of care. MAHS itself has created many such care sheets for a wide range of reptiles, amphibians, and invertebrates we believe to have straightforward care requirements, and thus make suitable family and beginner’s to intermediate level pets. Some species with much more complex, difficult to meet, or impracticable care requirements than what can be adequately explained in a one page care sheet may be multiple pages. We can also provide additional links, resources, and information on these species we feel are reliable and trustworthy if requested. If you would like to request a copy of a care sheet for any of the species listed below, or have a suggestion for an animal you don’t see on our list, contact us to let us know! Unfortunately, for liability reasons, MAHS is unable to create or publish care sheets for medically significant venomous species. This includes species in the families Crotilidae, Viperidae, and Elapidae, as well as the Helodermatidae (the Gila Monsters and Mexican Beaded Lizards) and some medically significant rear fanged Colubridae. Those that are serious about wishing to learn more about venomous reptile husbandry that cannot be adequately covered in one to three page care sheets should take the time to utilize all available resources by reading books and literature, consulting with, and working with an experienced and knowledgeable mentor in order to learn the ropes hands on. -
Spider Communities of "Yamskaya Steppe" Nature
The Kharkov Entomological Society Gazette 2002(2003) V10 (1-2) P. 99-107 SPIDER FAUNA (ARANEI) AND ASSEMBLAGES OF THE "YAMSKAYA STEPPE" NATURE RESERVE (BELGOROD AREA, RUSSIA) N. Yu. Polchaninova Kharkov National University, Ukraine polchaninva@mail. ru Introduction The fauna inventory in nature reserves has always been a topical issue. It is especially impor- tant in the steppe reserves that are the only places where the virgin steppes have been preserved. Until recently, the araneofauna of European meadow steppes has not been investigated evenly. The most complete data is given for the "Streletskaya Steppe" (Pichka, 1984 a,b; Polchaninova, 2003) where 160 species were recorded. 84 species are known for the "Kazatskaya Steppe" (Pol- chaninova, 2002) – both parts of the Central-Chermozyom reserve, Kursk Area. The first spider sampling in the "Yamskaya Steppe" was carried out by the members of the Club of young zoolo- gists of Kharkov Pioneer Palace in 1981-1982. The material was identified by the author, and 51 spider species were discovered (Yakushenko at all, 1984). Spiders, as numerous and diverse component of steppe biota, serve a suitable object for monitoring a state of animal communities of various habitats under the influence of different conservation managements. Material and Methods The "Yamskaya Steppe" is part of the "Belogorye" Nature Reserve and is situated in the Central Forest-Steppe in the Central Russian upland (Milkov, 1950). The main part of its terri- tory is occupied by meadow steppe, oak forest being located in a ravine. The steppe is divided into several parts with different mowing regime. There are un-mowed (i.e. -

Nieuwsbrief SPINED 32 2 ON SOME SPIDERS FROM GARGANO, APULIA, ITALY Steven IJland Gabriel Metzustraat 1, 2316 AJ Leiden ([email protected]) Peter J. van Helsdingen European Invertebrate Survey – Nederland, P.O. Box 9517, 2300 RA Leiden, Netherlands ([email protected]) Jeremy Miller Naturalis Biodiversity Center, P.O. Box 9517, 2300 RA Leiden, Netherlands ([email protected]) ABSTRACT In the springtime of 2011, 507 adult spiders (plus 7 identifiable subadults) representing a total of 135 species were collected in Gargano, Apulia, Italy. A list of collected spiders is given. Zelotes rinske spec. nov. is described after a single female. Dictyna innocens O. P.-Cambridge, 1872, Leptodrassus femineus (Simon, 1873), Nomisia recepta (Pavesi, 1880), Zelotes criniger Denis, 1937, Pellenes brevis (Simon, 1868), and Salticus propinquus Lucas, 1846 are reported for the first time from mainland Italy. Illustrations are provided of the problematic species Dictyna innocens O. P.-Cambridge, 1872. The poorly- known female of Araeoncus altissimus Simon, 1884 is described and depicted. 141 specimens representing 105 species were DNA barcoded. Key words: Araneae, barcoding, Zelotes rinske INTRODUCTION In the springtime of 2011, two of the authors (PJvH and SIJ) made a trip to Gargano in Italy in order to study spiders. Gargano is a peninsula situated in the province of Apulia (Puglia) and is known as the “spur” of the Italian “boot” (fig. 1). The Gargano promontory is rich in karst structures like caves and dolines. It has a very rich flora and fauna, and is known as one of the richest locations for orchids in Europe with some 56 species, some of which are endemic.
