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 Aquatic Insect Community in Penitentiary Glen, a Portage Escarpment Stream in Northeastern Ohio1
Copyright © 1984 Ohio Acad. Sci. 0030-0950/84/0003-0113 $2.00/0 THE AQUATIC INSECT COMMUNITY IN PENITENTIARY GLEN, A PORTAGE ESCARPMENT STREAM IN NORTHEASTERN OHIO1 DAVID J. ROBERTSON,2 Department of Biological Sciences, University of Pittsburgh, Pittsburgh, PA 15260 ABSTRACT. The aquatic insects inhabiting Penitentiary Glen, an isolated, high- gradient lotic habitat along Stoney Brook in Lake County, Ohio, were sampled during winter (December 1976), spring (May 1977), and summer (July 1977) months. Col- lections of immatures from dip nets and Surber samples were augmented with adult specimens taken in sweep nets and hand-picked from streamside rocks. Seventy-three species distributed among 60 genera in 7 orders were collected. Based on the diverse composition of the community dominated by organisms intolerant of organic en- richment, water quality in Stoney Brook is not significantly degraded. Community composition varies seasonally, with a trend toward a declining proportion of facultative organisms and increasing proportions of saproxenous and saprophobic organisms from winter through spring and into summer. Benthic diversity in Penitentiary Glen compares favorably with that in similar, relatively undisturbed northeastern Ohio streams, but the identity and proportional distribution of aquatic taxa varies considerably between streams.

Leppo4 Tetra Tech, Inc., 400 Red Brook Blvd., Suite 200, Owings Mills, Maryland 21117-5159 USA Abstract. Taxonomic identifications are central to biological assessment; thus, documenting and reporting uncertainty associated with identifications is critical. The presumption that comparable results would be obtained, regardless of which or how many taxonomists were used to identify samples, lies at the core of any assessment. As part of a national survey of streams, 741 benthic macroinvertebrate samples were collected throughout the eastern USA, subsampled in laboratories to ;500 organisms/sample, and sent to taxonomists for identification and enumeration. Primary identifications were done by 25 taxonomists in 8 laboratories. For each laboratory, ;10% of the samples were randomly selected for quality control (QC) reidentification and sent to an independent taxonomist in a separate laboratory (total n ¼ 74), and the 2 sets of results were compared directly. The results of the sample-based comparisons were summarized as % taxonomic disagreement (PTD) and % difference in enumeration (PDE). Across the set of QC samples, mean values of PTD and PDE were ;21 and 2.6%, respectively. -
(Insecta: Diptera) Assemblages Along an Andean Altitudinal Gradient
Vol. 20: 169–184, 2014 AQUATIC BIOLOGY Published online April 9 doi: 10.3354/ab00554 Aquat Biol Chironomid (Insecta: Diptera) assemblages along an Andean altitudinal gradient Erica E.

San Martín, CC 507, 5500 Mendoza, Argentina 2ILPLA, CCT CONICET La Plata, Boulevard 120 y 62 1900 La Plata, Argentina ABSTRACT: Chironomidae are an abundant, diverse and ecologically important group common in mountain streams worldwide, but their patterns of distribution have been poorly described for the Andes region in western-central Argentina. Here we examine chironomid assemblages along an altitudinal gradient in the Mendoza River basin to study how spatial and seasonal variations affect the abundance patterns of genera across a gradient of elevation, assess the effects of envi- ronmental variables on the chironomid community and to describe its diversity using rarefaction and Shannon’s indices. Three replicate samples and physicochemical parameters were measured seasonally at 11 sites in 2000 and 2001. Twelve genera of chironomid larvae were identified, which belonged to 5 subfamilies. Chironomid composition changed from the headwaters to the outlet and was associated with changes in altitude, water temperature, substrate size and conduc- tivity. We found a pronounced seasonal and spatial variation in the macroinvertebrate community and in physicochemical parameters. Environmental conditions such as elevated conductivity levels and increased river discharge occurring during the summer produced low chironomid density values at the sampling sites. The rarefaction index revealed that the sampling sites with highest richness were LU (middle section of the river) and PO (lower section). -
Spatial and Temporal Distribution of Aquatic Insects in the Dicle (Tigris) River Basin, Turkey, with New Records

Larvae, pupae, pupal exuviae, and nymphs of insects were obtained from samples collected by a plankton net monthly during a 1-year period in 2008 and 2009 at seven different sites of the Dicle (Tigris) River Basin. A total of 35 taxa from the orders Trichoptera (1 taxon), Ephemeroptera (3 taxa), and Diptera (31 taxa) were identified. Chironomidae (Diptera) was the most diverse group and was represented by three major subfamilies, namely Tanypodinae (2 taxa), Orthocladiinae (19 taxa), and Chironominae (7 taxa). Among these species, Nanocladius (Nanocladius) spiniplenus Saether, 1977 is a new record for Turkey as well as for western Asia. In addition, the Psychomyia larvae found for the first time in the Dicle (Tigris) River Basin (Turkey) were described. Both taxa have been illustrated to warrant validation. Taxa number varied spatially from 6 to 14 and temporally from 2 to 12 during the sampling period. Along the river, Cricotopus bicinctus and Orthocladius (S.) holsatus were the most common taxa.

In: Kahanpää J, Salmela J (Eds) Checklist of the Diptera of Finland. ZooKeys 441: 63–90. doi: 10.3897/zookeys.441.7461 Abstract A checklist of the family Chironomidae (Diptera) recorded from Finland is presented. Keywords Finland, Chironomidae, species list, biodiversity, faunistics Introduction There are supposedly at least 15 000 species of chironomid midges in the world (Armitage et al. 1995, but see Pape et al. 2011) making it the largest family among the aquatic insects. The European chironomid fauna consists of 1262 species (Sæther and Spies 2013). In Finland, 780 species can be found, of which 37 are still undescribed (Paasivirta 2012). The species checklist written by B. Lindeberg on 23.10.1979 (Hackman 1980) included 409 chironomid species. Twenty of those species have been removed from the checklist due to various reasons. The total number of species increased in the 1980s to 570, mainly due to the identification work by me and J. Tuiskunen (Bergman and Jansson 1983, Tuiskunen and Lindeberg 1986). -

A MORPHOF ETRIC ANALYSIS OF THE CULICOIDES PULICARIS SPECIES COMPLEX (n.1'1 (DIPTERA: CERATOPOGONIDAE) ) stet '1+ nf ? 1`r3 I1 BY Richard Paul Lane, B.Sc. (London), A.R.C.S. A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Imperial College Department of Zoology and Applied Entomology, Imperial College, London, S.W.7. August 1979 ABSTRACT This study assesses the value of currently available multivariate morphometric techniques in the analysis of the Culicoides pulicaris complex. This midge complex is typical of species groups which are difficult to separate into discrete clusters (species). Initially, emphasis is given to the study of eight nominal taxa in Britain: C. delta Edwards, fagineus Edwards, grisescens Edwards, impunctatus Goetghebuer,.lupicaris Downes & Kettle, newsteadi Austen, pulicaris Linnaeus and punctatus Meigen. Subsequently, material from other parts of the Palaearctic Region is included. Morphological characters of adults are tested to evaluate the nature and extent of variation. Size is rejected as unreliable, since both intraspecific and seasonal variation is excessive. Allometry of size in legs, antennae and palps is studied in large homogeneous samples of three species and the implications for taxonomy discussed. A new system for coding wing pattern,utilising pattern elements, is developed and compared to a mechanical scanning method. The former, based on only 13 characters, is preferable, on practical and theoretical grounds, to the scanning method involving 420 characters. In constructing a classification, two points are considered. Firstly, whether a large number of characters is required for a reliable classification and secondly, whether the recognised species are homogeneous. -

Box 676, 13565-905, Sa˜ o Carlos, SP, Brazil Received 5 June 2013; Accepted 11 September 2013 Abstract – The genus Nanocladius Kieffer, 1913 (Diptera: Chironomidae: Orthocladiinae) has been frequently found in aquatic habitats of the Neotropical region. However, until now only one species was described living symphoretically on Ephemeroptera and no free-living species has been cited or formally described from the region. In the present study, two new species of Nanocladius are described and figured as male, pupa and larva: N. communis and N. longispicula. The specimens were collected from different streams in Brazil and are the first recorded species of the genus to the country. Key words: Brazil / Chironomidae / Nanocladius / immature stages / taxonomy Introduction The Holarctic species of the genus were described and revised by several authors (e.g., Sæther, 1977; Non-biting midges of the genus Nanocladius are Niitsuma, 1991; Harrison, 1994; Fu and Wang, 2009), minute dipterans with worldwide distribution.

INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left handcorner of a large sheetand to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.
