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. -

Nitrogen Content in Riparian Arthropods Is Most Dependent on Allometry and Order
Wiesenborn: Nitrogen Contents in Riparian Arthropods 71 NITROGEN CONTENT IN RIPARIAN ARTHROPODS IS MOST DEPENDENT ON ALLOMETRY AND ORDER WILLIAM D. WIESENBORN U.S. Bureau of Reclamation, Lower Colorado Regional Office, P.O. Box 61470, Boulder City, NV 89006 ABSTRACT I investigated the contributions of body mass, order, family, and trophic level to nitrogen (N) content in riparian spiders and insects collected near the Colorado River in western Arizona. Most variation (97.2%) in N mass among arthropods was associated with the allometric effects of body mass. Nitrogen mass increased exponentially as body dry-mass increased. Significant variation (20.7%) in N mass adjusted for body mass was explained by arthropod order. Ad- justed N mass was highest in Orthoptera, Hymenoptera, Araneae, and Odonata and lowest in Coleoptera. Classifying arthropods by family compared with order did not explain signifi- cantly more variation (22.1%) in N content. Herbivore, predator, and detritivore trophic-levels across orders explained little variation (4.3%) in N mass adjusted for body mass. Within or- ders, N content differed only among trophic levels of Diptera. Adjusted N mass was highest in predaceous flies, intermediate in detritivorous flies, and lowest in phytophagous flies. Nitro- gen content in riparian spiders and insects is most dependent on allometry and order and least dependent on trophic level. I suggest the effects of allometry and order are due to exoskeleton thickness and composition. Foraging by vertebrate predators, such as insectivorous birds, may be affected by variation in N content among riparian arthropods. Key Words: nutrients, spiders, insects, trophic level, exoskeleton, cuticle RESUMEN Se investiguo las contribuciones de la masa de cuerpo, orden, familia y el nivel trófico al con- tenido de nitógeno (N) en arañas e insectos riparianos (que viven en la orilla del rio u otro cuerpo de agua) recolectadaos cerca del Rio Colorado en el oeste del estado de Arizona. -
Molecular Insights Into the Phylogenetic Structure of the Spider
MolecularBlackwell Publishing Ltd insights into the phylogenetic structure of the spider genus Theridion (Araneae, Theridiidae) and the origin of the Hawaiian Theridion-like fauna MIQUEL A.

Molecular insights into the phylo- doi:10.1111/j.1463-6409.2007.00280.x genetic structure of the spider genus Theridion (Araneae, Theridiidae) and the origin of the Hawaiian Theridion-like fauna. — Zoologica Scripta, 36, 337–352. The Hawaiian happy face spider (Theridion grallator Simon, 1900), named for a remarkable abdominal colour pattern resembling a smiling face, has served as a model organism for under- standing the generation of genetic diversity. Theridion grallator is one of 11 endemic Hawaiian species of the genus reported to date. Asserting the origin of island endemics informs on the evolutionary context of diversification, and how diversity has arisen on the islands. Studies on the genus Theridion in Hawaii, as elsewhere, have long been hampered by its large size (> 600 species) and poor definition. Here we report results of phylogenetic analyses based on DNA sequences of five genes conducted on five diverse species of Hawaiian Theridion, along with the most intensive sampling of Theridiinae analysed to date. Results indicate that the Hawai- ian Islands were colonised by two independent Theridiinae lineages, one of which originated in the Americas. Both lineages have undergone local diversification in the archipelago and have convergently evolved similar bizarre morphs. Our findings confirm para- or polyphyletic status of the largest Theridiinae genera: Theridion, Achaearanea and Chrysso. -
Hygropetric and Litter-Inhabiting Spiders (Araneae) from the Abruzzo Apennines (Central Italy)
Arachnol. Mitt. 37: 15-26 Nürnberg, Juli 2009 Hygropetric and litter-inhabiting spiders (Araneae) from the Abruzzo Apennines (Central Italy) Marco Isaia, Giuseppe Osella & Giovanna Pannunzio Abstract: We present the results of a study of spider material extracted by means of Berlese apparatus from wet mosses and by litter sieving in broadleaf woods within several natural reserves of the Abruzzo region (Central Italy). The main aim of the work is to contribute to the knowledge of the spider fauna of the Apen- nines; currently one of the lesser known in Italy. In total, 520 spiders, belonging to 49 species and 14 families were collected. The most abundant and diverse family was Linyphiidae, with 278 individuals belonging to 22 species. Altogether we provide 28 new records for the Abruzzo region, including two species of Theridiidae, twenty of Linyphiidae, four of Hahniidae and two of Thomisidae. We also present additional unpublished records of several rare, litter-inhabiting species collected by litter sieving in the same area. Data on habitat preferences and details on the Italian distribution of the rarest species are presented. Key words: Berlese apparatus, Dysderidae, Linyphiidae, litter sieving, National Park of Gran Sasso, National Park of Monti della Laga, regional fauna Hygropetric habitats become established on rocky published records of several rare, litter-inhabiting or soil surfaces, with thin water films moving down species collected by litter sieving in the same area, in a mostly laminar flow. This habitat is colonised including details on their Italian distribution and mainly by bryophytes (mosses and peat-mosses) habitat preference. and often harbours unique assemblages of arthro- pods, characterised by endemic or rare species. -

Biodiversity and Conservation of Iberian Spiders: Past, Present and Future
Boletín Sociedad Entomológica Aragonesa, n1 42 (2008) : 487–492. Jornadas sobre Biodiversidad valenciana y Arácnidos. VIII Jorndas G.I.A. 25-28 octubre 2007. Valencia. Biodiversity and conservation of Iberian spiders: past, present and future Pedro Cardoso Azorean Biodiversity Group – CITA-A, Universidade dos Açores, Angra do Heroísmo, Portugal. Correspondence: Universidade dos Açores, Departamento de Ciências Agrárias, Terra-Chã, 9701-851 Angra do Heroísmo, Portugal. – [email protected] Abstract: The knowledge of Iberian spider species and their distributions has undergone several development stages. The ac- cumulation of knowledge, reinforced by the emergence on the last years of several associations devoted to the study of arach- nids, allowed us to currently register more than 1300 species in the Iberian Peninsula. In a project started by Eduardo Morano and now with my cooperation, the new Iberian spider catalogue is being developed and is partly available online. However, even if all existing data are compiled, they still present two main problems. Firstly, they are incomplete for the vast majority of the species. Secondly, the heterogeneity of the studies that recorded the data does not allow direct or reliable comparisons between areas. Both the reasonable completeness of the data and its comparability are essential for, among oth- ers, biogeography and conservation studies. These two targets can only be guaranteed by the use of optimized and standar- dized sampling protocols. Based on intensive fieldwork made in different areas and habitats in Portugal, a flexible sampling pro- tocol has been developed which, will allow different teams with multiple objectives to compare results among each other, a pro- cedure not possible until the present.
