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. -
Unexpected Diversity in Neelipleona Revealed by Molecular Phylogeny Approach (Hexapoda, Collembola)
S O I L O R G A N I S M S Volume 83 (3) 2011 pp. 383–398 ISSN: 1864-6417 Unexpected diversity in Neelipleona revealed by molecular phylogeny approach (Hexapoda, Collembola) Clément Schneider1, 3, Corinne Cruaud2 and Cyrille A. D’Haese1 1 UMR7205 CNRS, Département Systématique et Évolution, Muséum National d’Histoire Naturelle, CP50 Entomology, 45 rue Buffon, 75231 Paris cedex 05, France 2 Genoscope, Centre National de Sequençage, 2 rue G. Crémieux, CP5706, 91057 Evry cedex, France 3 Corresponding author: Clément Schneider (email: [email protected]) Abstract Neelipleona are the smallest of the four Collembola orders in term of species number with 35 species described worldwide (out of around 8000 known Collembola). Despite this apparent poor diversity, Neelipleona have a worldwide repartition. The fact that the most commonly observed species, Neelus murinus Folsom, 1896 and Megalothorax minimus Willem, 1900, display cosmopolitan repartition is striking. A cladistic analysis based on 16S rDNA, COX1 and 28S rDNA D1 and D2 regions, for a broad collembolan sampling was performed. This analysis included 24 representatives of the Neelipleona genera Neelus Folsom, 1896 and Megalothorax Willem, 1900 from various regions. The interpretation of the phylogenetic pattern and number of transformations (branch length) indicates that Neelipleona are more diverse than previously thought, with probably many species yet to be discovered. These results buttress the rank of Neelipleona as a whole order instead of a Symphypleona family. Keywords: Collembola, Neelidae, Megalothorax, Neelus, COX1, 16S, 28S 1. Introduction 1.1. Brief history of Neelipleona classification The Neelidae family was established by Folsom (1896), who described Neelus murinus from Cambridge (USA). -

The checklist of Collembola from the Republic of Moldova including 223 species is presented. The list is based on literature sources and personal collecting. Résumé. Ce travail présente la liste des 223 espèces de collemboles de la République de Moldova. Cette liste fut réalisée en utilisant des références littéraires et des collections personnelles. Key words: Collembola, checklist, Republic of Moldova. INTRODUCTION The records on Collembola from the Republic of Moldova started about 50 years ago with the first two species included by Martynova in “The key to insects of the European part of the USSR. Collembola” (1964). Some more information on species diversity of Collembola from the soil of Moldavian vineyards was included in Stegãrescu’s work (1967). During the last twenty years, this group has been studied more systematically, with more than 200 species recorded (Buºmachiu 2001, 2004, 2006 a, b, 2008). Since 2002, eleven species new to science were described from the Republic of Moldova by da Gama & Buºmachiu (2002, 2004); Buºmachiu & Deharveng (2008) and Buºmachiu & Weiner (2008). Until now, the faunistic data on Collembola from the Republic of Moldova have not been summarised in the form of a checklist. The present paper includes the complete list of Collembola from the Republic of Moldova using the modern nomenclature. Totally, 223 species are listed. Some problematic and dubious species, such as Pseudanurida clysmae Jackson, 1927, Onychiurus fimetarius (Linnaeus, 1758) and Orchesella divergens Handschin, 1929 recorded by Stegãrescu (1967) and Pseudosinella wahlgrei Börner, 1907, are not included in the list. -

One insect group which reacts sensitively to habitat changes are the rove beetles contributing to the maintenance of an undisturbed insect succession during decomposition by mainly hunting fly maggots. However, little is known about carrion-associated rove beetles due to poor taxonomic knowledge. In our study, we unveiled the human-induced and environmental drivers that modify rove beetle communities on vertebrate cadavers. At German forest sites selected by a gradient of management intensity, we contributed to the understanding of the rove beetle-mediated decomposition process. One main result is that an increasing human impact in forests changes rove beetle communities by promoting generalist and more open-habitat species coping with low structural heterogeneity, whereas species like Philonthus decorus get lost. -

The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

Phlaeothripidae: Thysanoptera
Vol. XXII, No. 3, December, 1977 495 A Review of the Hawaiian Species of Idolothripinae (Phlaeothripidae: Thysanoptera) K. Sakimura and F. A. Bianchi BISHOP MUSEUM, HONOLULU, HAWAII Published knowledge of the Hawaiian tubuliferous thrips fauna is meager. This is largely due to the limited extent to which our findings have been reported in the past. Those accumulated findings are being jointly reported in this paper and in others to follow. The primary objective of these papers is to assemble all the information on these thrips together in a ready reference available for local use. All the Hawaiian literatures will be completely cited. Recent innovations in the systematics of the suborder Tubulifera, specifically the two major contributions by Mound (1974a, b) on the Pacific Idolothripinae, provided impetus to the study of the Hawaiian species. The last review of the Hawaiian Thysanoptera (Zimmerman 1948) is in need of extensive clarifications and additions. It listed only six idolothripine species. In the present review, one synonymy and two nomenclatural changes are reported, and four more species, including one new to science, are added. A new idolothripine species described subsequent to the last review was found to have been misplaced in this subfamily. Among nine species listed here, only three are considered endemic to the Hawaiian Islands. Materials accumulated in the Sakimura Collection and the Bishop Museum Collection are all pooled in this work. The Bianchi Collection, which included the HSPA Collection and the Hawaiian Entomological Society Collection, is now deposited in the Bernice P. Biship Museum. In our listings of "Material Studied" and "Earlier Collection Recorded", specimens from the Sakimura Collection are all specified by his accession numbers, and those from the Bishop Museum Collection are marked with an asterisk. -

A Summary List of Fossil Spiders
A summary list of fossil spiders compiled by Jason A. Dunlop (Berlin), David Penney (Manchester) & Denise Jekel (Berlin) Suggested citation: Dunlop, J. A., Penney, D. & Jekel, D. 2010. A summary list of fossil spiders. In Platnick, N. I. (ed.) The world spider catalog, version 10.5. American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last udated: 10.12.2009 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the spider fossil record and numerous new taxa have been described. As part of a larger project to catalog the diversity of fossil arachnids and their relatives, our aim here is to offer a summary list of the known fossil spiders in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list follows the names and sequence of families adopted in the Catalog. For this reason some of the family groupings proposed in Wunderlich’s (2004, 2008) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions. Extinct families have been inserted in the position which we hope best reflects their probable affinities. Genus and species names were compiled from established lists and cross-referenced against the primary literature. -
Relative and Seasonal Abundance of Beneficial Arthropods in Centipedegrass As Influenced by Management Practices
HORTICULTURAL ENTOMOLOGY Relative and Seasonal Abundance of Beneficial Arthropods in Centipedegrass as Influenced by Management Practices S. KRISTINE BRAMAN AND ANDREW F. PENDLEY Department of Entomology, University of Georgia, College of Agriculture Experiment Stations, Georgia Station, Griffin, GA 30223 J. Econ. Entomol. 86(2): 494-504 (1993) ABSTRACT Pitfall traps were used to monitor the seasonal activity of arthropod preda tors, parasitoids, and decomposers in replicated plots of centipedegrass turf for 3 yr (1989-1991) at two locations. During 1990 and 1991, the influence of single or combined herbicide, insecticide, and fertilizer applications on these beneficials was assessed. In total, 21 species of carabids in 13 genera and 17 species of staphylinids in 14 genera were represented in pitfall-trap collections. Nonsminthurid collembolans, ants, spiders, and parasitic Hymenoptera were adversely affected in the short term by insecticide applica tions targeting the twolined spittlebug, Prosapia bicincta (Say). Other taxa, notably orib atid Acari, increased over time in response to pesticide or fertilizer applications. Although various taxa were reduced by pesticide application during three of four sample intervals, a lack ofoverall differences in season totals suggests that the disruptive influence ofcertain chemical management practices may be less severe than expected in the landscape.
