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. -
A Taxonomic Revision of the Orb Weaver Genus Acacesia (Araneae: Araneidae)
A TAXONOMIC REVISION OF THE ORB WEAVER GENUS ACACESIA (ARANEAE: ARANEIDAE) BY St3sAy GIt3Ec< ABSTRACT There are five species of Acacesia which range collectively from southern North America to Argentina. Two are previously known members of the genus, A. cornigera Petrunkevitch and A. hamata (Hentz). Three of these are new species: A. villalobosi and A. yacuiensis, from southern Brazil, and A. benigna from Bolivia and Peru. INTRODUCTION Acacesia is a genus of orb-weaving spiders common and endemic to the Americas, proposed by Simon in 1892. Hentz named the type species Epeira foliata in 1847. The genus con- tained the single species A. hamata until Petrunkevitch (1925) described A. cornigera. Subsequently published names, illustra- tions, and descriptions of new species of Acacesia have turned out to be synonyms of the two extant species (Chamberlin and Ivie 1936, Badcock 1932). Levi (1976) redescribed A. hamata in a revi- sion of Nearctic orb weaver genera, mentioning the Neotropical A. cornigera in passing. He hypothesized at the time that "there are three or four additional species of Acacesia, all Neotropical and all similar in appearance." The specimens I have examined for the current taxonomic revision corroborate this statement, and I expand the genus to include three new South American species. This study represents an addition to Levi's ongoing project of revising Neotropical orb weavers. I here report the results of my taxonomic project for which I examined and illustrated over 350 museum specimens. I describe factors I considered in delimiting new species such as their Harvard College, Harvard University, Cambridge, MA 02138 current address: Department of Entomology, Comstock Hall, Cornell University, Ithaca, NY 14853 Manuscript received 7 July 1993. -

Identification Key to the Subfamilies of Ichneumonidae (Hymenoptera)
Identification key to the subfamilies of Ichneumonidae (Hymenoptera) Gavin Broad Dept. of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Notes on the key, February 2011 This key to ichneumonid subfamilies should be regarded as a test version and feedback will be much appreciated (emails to [email protected]). Many of the illustrations are provisional and more characters need to be illustrated, which is a work in progress. Many of the scanning electron micrographs were taken by Sondra Ward for Ian Gauld’s series of volumes on the Ichneumonidae of Costa Rica. Many of the line drawings are by Mike Fitton. I am grateful to Pelle Magnusson for the photographs of Brachycyrtus ornatus and for his suggestion as to where to include this subfamily in the key. Other illustrations are my own work. Morphological terminology mostly follows Fitton et al. (1988). A comprehensively illustrated list of morphological terms employed here is in development. In lateral views, the anterior (head) end of the wasp is to the left and in dorsal or ventral images, the anterior (head) end is uppermost. There are a few exceptions (indicated in figure legends) and these will rectified soon. Identifying ichneumonids Identifying ichneumonids can be a daunting process, with about 2,400 species in Britain and Ireland. These are currently classified into 32 subfamilies (there are a few more extralimitally). Rather few of these subfamilies are reconisable on the basis of simple morphological character states, rather, they tend to be reconisable on combinations of characters that occur convergently and in different permutations across various groups of ichneumonids. -

C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. -
Arthropods of Elm Fork Preserve
Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux. -
Observations of Cerceris Fumipennis (Hymenoptera: Crabronidae) Phenology and Variation in Its Buprestid Prey in Louisiana C
Observations of Cerceris fumipennis (Hymenoptera: Crabronidae) phenology and variation in its buprestid prey in Louisiana C. Wood Johnson1,*, Ted C. MacRae2, Cavell Brownie3, Warren Virgets III4, and Jeremy D. Allison5 Abstract The non-native emerald ash borer,Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), threatens extirpation of susceptible ash (Fraxinus species; Lamiales: Oleaceae) in North America. Cerceris fumipennis Say (Hymenoptera: Crabronidae), a ground-nesting wasp that preys on Buprestidae in eastern North America, is used as a survey tool for the emerald ash borer in the northeastern U.S. and Canada. The recent detection of the emerald ash borer in Louisiana provides an opportunity to complement trapping surveys with the use of C. fumipennis, but knowledge of C. fumipennis in the region is lacking. From 2011 to 2014, we conducted searches at 155 sites and located C. fumipennis aggregations at 25% (n = 39) of these sites; 36% (n = 14) of these were located at forest harvests, an aggregation habitat not previously reported in the literature. We collected 1,559 buprestids representing 35 species from 2 aggregations in Louisiana between May and Aug 2012. Buprestid collections at these aggregations and observations of C. fumipennis activity at a 3rd aggregation indicated the number of buprestid species and individuals collected declined significantly from May to Jul. We collected significantly moreAgrilus difficilis Gory (Coleoptera: Buprestidae) in the afternoon than morning hours and observed similar diurnal patterns among other buprestid species during the early weeks following aggregation activation. We also discuss evidence suggesting a portion of the regional C. fumipennis population is bivoltine. AlthoughA. planipennis was not collected during this study, our results suggest that C. -
Opsin Duplication and Subfunctionalization for Short-Wavelength Sensitivity in Jewel Beetles (Coleoptera: Buprestidae) Nathan P
Lord et al. BMC Evolutionary Biology (2016) 16:107 DOI 10.1186/s12862-016-0674-4 RESEARCH ARTICLE Open Access A cure for the blues: opsin duplication and subfunctionalization for short-wavelength sensitivity in jewel beetles (Coleoptera: Buprestidae) Nathan P. Lord1*, Rebecca L. Plimpton2, Camilla R. Sharkey1, Anton Suvorov1, Jonathan P. Lelito3, Barry M. Willardson2 and Seth M. Bybee1 Abstract Background: Arthropods have received much attention as a model for studying opsin evolution in invertebrates. Yet, relatively few studies have investigated the diversity of opsin proteins that underlie spectral sensitivity of the visual pigments within the diverse beetles (Insecta: Coleoptera). Previous work has demonstrated that beetles appear to lack the short-wavelength-sensitive (SWS) opsin class that typically confers sensitivity to the “blue” region of the light spectrum. However, this is contrary to established physiological data in a number of Coleoptera. To explore potential adaptations at the molecular level that may compensate for the loss of the SWS opsin, we carried out an exploration of the opsin proteins within a group of beetles (Buprestidae) where short-wave sensitivity has been demonstrated. RNA- seq data were generated to identify opsin proteins from nine taxa comprising six buprestid species (including three male/female pairs) across four subfamilies. Structural analyses of recovered opsins were conducted and compared to opsin sequences in other insects across the main opsin classes—ultraviolet, short-wavelength, and long-wavelength. Results: All nine buprestids were found to express two opsin copies in each of the ultraviolet and long-wavelength classes, contrary to the single copies recovered in all other molecular studies of adult beetle opsin expression. -
The Influence of Induced Host Moisture Stress on the Growth and Development of Western Spruce Bud Worm and Armillaria Ostoyae on Grand Fir Seedlings
AN ABSTRACT OF THE THESIS OF Catherine Gray Parks for the degree of Doctor of Philosophy in the Department of Forest Science, presented on April 28, 1993. Title: The Influence of Induced Host Moisture Stress on the Growth and Development of Western Spruce Budworm and Armillaria ostoyae on Grand Fir Seedlings. Abstract Approved: John D. Waistad This greenhouse study evaluates the influence of separately and simultaneously imposed water stress, western spruce budworm (Choristorneura occidentalis Freeman) defoliation, and inoculation with the root pathogen, Armillaria ostoyae (Romagn.) Herink, on the growth and biochemical features of Abies .grandis (Dougl.) Lindi. Seedling biomass, plant moisture status, bud phenology, and allocation patterns of phenolics, carbohydrates, and key nutrients (nitrogen, phosphorus, potassium and sulfur) are reported. Hypotheses are developed and testedon the impacts of water-stress, defoliation, and root inoculation, on westernspruce budworm growth and development, and Armillaria ostoyae-caused mortality and infection. Western spruce budworm larvae fedon water-stressed seedlings had higher survival rates, grew faster, and produced largerpupae than those fed on well- watered seedlings. There is no clear reason for the positive insectresponse, but changes in foliage nutrient patterns and phenolic chemistryare indicated. Insect caused defoliation has been earlier reported to enhance successful colonization of Armillaria spp. on deciduous trees in the forests of the northeastern United States. The positive response of the fungus was attributed to a weakened tree condition. Conversely, although this study conclusively found water-limited trees to have increased susceptibility to A. ostoyae, defoliation significantly lowered Armillaria-caused infection and mortality. The decline in infection success is attributed to defoliation-caused reduction in plant water stress and an alteration of root carbohydrate chemistry.
