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 Diptera of Lancashire and Cheshire: Craneflies and Winter Gnats
The Diptera of Lancashire and Cheshire: Craneflies and Winter Gnats by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] Version 1.1 26 November 2017 1 Summary This document provides a new checklist for the craneflies and winter gnats (Tipuloidea, Ptychopteridae and Trichoceridae) to extend the lists of the diptera of Lancashire and Cheshire first published by Kidd and Bindle in 1959. Overall statistics on recording activity are given by decade and hectad. Checklists are presented for each of the three Watsonian vice-counties 58, 59, and 60 detailing for each species the number of records, year of earliest and most recent record, and the number of hectads with records. A combined checklist showing distribution by the three vice-counties is also included, covering a total of 264 species, amounting to 75% of the current British checklist. Introduction This report is the third in a series to update and extend the partial checklist of the diptera of Lancashire and Cheshire published in 1959 by Leonard Kidd and Alan Brindle1. There were two previous updates, in 19642 and 19713. The previous reports in this series cover the soldierflies and allies4 and the Sepsidae5, the latter family not having been covered in Ref 1. The reader is referred to the first two reports for the background and rationale of these checklists, as well as the history of diptera recording and available data sources. The description of methodology is also kept to a minimum in the present report: only significant differences from the previous publications will be outlined. -
Structure of the Coxa and Homeosis of Legs in Nematocera (Insecta: Diptera)
Acta Zoologica (Stockholm) 85: 131–148 (April 2004) StructureBlackwell Publishing, Ltd. of the coxa and homeosis of legs in Nematocera (Insecta: Diptera) Leonid Frantsevich Abstract Schmalhausen-Institute of Zoology, Frantsevich L. 2004. Structure of the coxa and homeosis of legs in Nematocera Kiev-30, Ukraine 01601 (Insecta: Diptera). — Acta Zoologica (Stockholm) 85: 131–148 Construction of the middle and hind coxae was investigated in 95 species of Keywords: 30 nematoceran families. As a rule, the middle coxa contains a separate coxite, Insect locomotion – Homeotic mutations the mediocoxite, articulated to the sternal process. In most families, this coxite – Diptera – Nematocera is movably articulated to the eucoxite and to the distocoxite area; the coxa is Accepted for publication: radially split twice. Some groups are characterized by a single split. 1 July 2004 The coxa in flies is restricted in its rotation owing to a partial junction either between the meron and the pleurite or between the eucoxite and the meropleurite. Hence the coxa is fastened to the thorax not only by two pivots (to the pleural ridge and the sternal process), but at the junction named above. Rotation is impossible without deformations; the role of hinges between coxites is to absorb deformations. This adaptive principle is confirmed by physical modelling. Middle coxae of limoniid tribes Eriopterini and Molophilini are compact, constructed by the template of hind coxae. On the contrary, hind coxae in all families of Mycetophiloidea and in Psychodidae s.l. are constructed like middle ones, with the separate mediocoxite, centrally suspended at the sternal process. These cases are considered as homeotic mutations, substituting one structure with a no less efficient one. -

W obrębie koziułkowatych (Tipulidae) z podrodziny Ctenophorinae w Zachodniej Palearktyce stwierdzono występowanie piętnastu gatunków i podgatunków zaliczanych do czterech rodzajów: Ctenophora MEIGEN, Dic- tenidia BRULLÉ, Phoroctenia COQUILLETT oraz Tanyptera LATREILLE (OOSTERBROEK i in. 2006). Dotychczas w Polsce wykazano siedem z nich (SKIBIŃSKA, CHUDZICKA 2007). Muchówki te z reguły są nieliczne, a niekie- dy nawet bardzo rzadkie. Ich występowanie ogranicza się do starych lasów, z zachowanymi licznymi próchniejącymi martwymi drzewami (głównie re- zerwatów przyrody). Gatunki z tej podrodziny zagrożone są wyginięciem na skutek usuwania z lasu martwego drewna i starych drzew (PALACZYK i in. 2002; PALACZYK 2004).

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Species richness of terrestrial and freshwater biota generally decreases with increasing latitude. Some taxa, however, show an anomalous species richness pattern in a regional or global scale. The aim of this study was to examine (i) regional variation in species richness, (ii) faunistic composition, (iii) occupancy, and (iv) proportions of different distribution types of Finnish crane flies. Analyses were based on incidence data pooled into 20 biogeographical provinces. Finnish crane fly fauna consists of 335 species; the provincial richness varies from 91 to 237. The species richness of all species and saproxylic/fungivorous species decreased with increasing latitude; mire-dwelling crane flies displayed a reversed pattern (Spearman’s correlations). Thirty-one species occupied a single province and 11 species were present in all provinces. Provincial assemblages showed a strong latitudinal gradient (NMS ordination) and faunistic distance increased with increasing geographical distance (Mantel test). Nearly half (48%) of the Finnish crane flies are Trans-Palaearctic, roughly one-third (34%) are West Palaearctic, and only 16 and 2% are Holarctic and Fennoscandian, respectively. -

The paper includes records from the literature, collections and recent collect- ing. The Tipulidae of Sardinia can be divided into two groups of about equal size: one group of species endemic or subendemic to geographic Italy, and another group with species that are more widespread. About 10% of the species are strictly endemic of the island, while 23% are endemic to Sardinia and Corsica. Key words: Tipulidae, cranefl ies, Sardinia, Italy, endemism. RIASSUNTO I Tipulidi della Sardegna (Diptera: Tipulidae) È fornita una rassegna delle 31 specie di Tipulidae note della Sardegna. Il lavoro include dati di letteratura, museali e di recenti raccolte. I Tipulidae della Sardegna possono essere divisi in due gruppi, circa della stessa dimensione: uno comprende specie endemiche o subendemiche dell'Italia geografi ca, l'altro comprende specie che sono più ampiamente diffuse. Circa il 10% delle specie è strettamente endemico dell'isola e il 23% è endemico di Sardegna e Corsica. INTRODUCTION The larvae feed on a variety of material such as de- caying plant and animal matter, mosses and algae. Tipulidae are medium- to large-sized, slender-bodied A few species, especially in Tipula (Tipula Linnaeus, nematocerous Diptera, and include some of the larg- 1758) and Nephrotoma Meigen, 1803, are destructive est forms among the Nematocera (body length up to feeders on pasture grasses, seedlings and crops and 60 mm, wing length up to 40 mm). -

Foxhunting and the Landscape Between 1700 and 1900; with Particular Reference to Norfolk and Shropshire
Foxhunting and the landscape between 1700 and 1900; with particular reference to Norfolk and Shropshire Jane Bevan Degree of Doctor of Philosophy University of East Anglia School of History October 2011 This copy of the thesis has been supplied on the condition that anyone who consults it is understood to recognise that its copyright rests with the author and that no quotation from the thesis, nor any information derived from it, may be published without acknowledgement Abstract This thesis explores the history of foxhunting from 1700 to 1900. It examines how perceptions of an ideal hunting country, and what constituted an elite quarry, altered in tandem with alterations to the English lowland countryside. The relationship between the landscape and changes bought about by the upheaval of enclosure and agricultural development are discussed, in the context of the evolution in practice and geographical spread of foxhunting, at a national, regional and county-wide level. Several long-held beliefs are challenged. The social history of foxhunting and the increased participation of both ‘polite’ urban neophytes and prosperous tenant farmers during the two centuries is compared with the declining involvement of women. The impact of hunt clubs and the rise of subscription packs in the two study areas is contrasted. The influence of changes in the landscape on foxhunting is considered alongside the reciprocal impact of foxhunters manipulating the physical surroundings to enhance their sport. A detailed study of the history of hunting and its most iconic feature, the covert, in Norfolk and Shropshire highlights the importance of landowners control over the countryside. -

Recent records, especially from western and northern parts of Poland, show that the species is more widespread than previously known. Key words: Diptera, Tipulidae, Ctenophora omata, new records, Poland Introduction Among the crane flies (Tipulidae), all the species of genus Ctenophora Meigen, 1803 are large and often ichneumon or wasp-like. The body is frequently polished and coloured black with large yellow, orange or red markings. The genus comprises ten species in the West Palaearctic. So far, five of them have been recorded from Poland and they are classified into the subgenus Cnemoncosis Enderlein, 1921: C. omata Meigen, 1818 and C. factuosa Loew, 1871 and into the subgenus Ctenophora s. str.: C. flaveolata (Fabricius, 1794), C. guttata Wiedemann, 1818 and C. pectininicornis (Linnaeus, 1758) (Skibińska, Chudzicka 2007). All Ctenophora species are rare in Poland and are listed in the Red List of Threatened Animals in Poland (Palaczyk et al. 2002). Among the genus Ctenophora the rarest is C. omata (Fig. 1) and this species is the only listed in the Polish Red Data Book of Animals with category vulnerable (Palaczyk 2004).
