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.

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.

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).

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).

Inventariou-se a fauna de Chironomidae presente no sul do estado do Tocantins, Brasil. Foram realizadas seis coletas bimestrais em 45 locais de coleta com características lóticas no ano de 2006. O material foi coletado manualmente em diversos ambientes, onde verificou-se a abundância e a constância de Chironomidae. A partir do material coletado identificou-se 511 espécimes, montados em lâminas permanentes. Registramos a ocorrência de 30 gêneros distribuídos em três subfamílias (Chironominae, Orthocladiinae e Tanypodinae). Orthocladiinae foi a mais abundante constituindo 55% do total das larvas identificadas. Cricotopus foi o gênero mais abundante, representando 35,20% das larvas totais identificadas, seguido de Thienemanniella 14,85%, Rheotanytarsus 13,65% e Polypedilum 11,90%. A subfamília que apresentou o maior número de gêneros foi Chironominae com 18. O local de coleta mais abundante foi ENP1 com 70 espécimes, seguido de ENPN15 com 65. Os locais ENPN14 e ENP1 foram os que apresentaram o maior número de gêneros, com 11 em cada, ENP1 apresentou o maior número de gêneros acessórios com seis, seguido de EN147 com três gêneros acessórios.

Herrmann2, and J.E. Sublette3 ABSTRACT.—Mining in the Upper Arkansas catchment has polluted the river with heavy metals for 140 yr. Pupal and adult chironomid species distribution and sedimentary metal concentrations are provided for 22 stations along 259 km of main river during 1984–85. Complete species identification was achieved only recently. This has produced an unprece- dented record of chironomid species distribution for a comparable length of river in the USA.
