The Occurrence of Some Coleoptera in Grass Tussocks, with Special Reference to Michocli1jatic Conditions 1 THE OCCURRENCE OF SOME COLEOPTERA IN GRASS TUSSOCKS, WITH SPECIAL REFERENCE TO MICHOCLI1JATIC CONDITIONS. By M.L.Luff, B.Sc., A.R.C.S. October, 1964. Imperial College Field Station, Silwood Park, Sunninghill, Ascot, Berkshire. 2 ABSTRACT In this thesis the beetle fauna of grass tussocks is investigated, and the possible importance of the tussocks to the beetles studied. The first section describes the microbabitat in which the beetles live. The occurrence of grass tussocks at Silwood is outlined, and the morphology and growth of Dactylis glomerate L. is described. The micro - climate, especially temperature, in tussocks throughout the year is studied, and compared with that in the intervening grass. The second section deals with the beetle fauna of tussocks. The numbers and species of beetles found both in and between the tussocks throughout the year are studied, and the species which are regular inhabitants of tussocks are listed. An account of the biology of four of these common species is given, with particular reference to the imp- ortance of the tussocks in their biology, and to the stage of the life cycle at which this microhabitat is selected. In the third section, possible effects of the tussocks on the fauna are considered. The behaviour of three common species is investigated with reference to the responses which keep them in tussocks during winter. Some aspects of their movement in and out of tussocks are investigated. The resistance of the three species to cold is studied, and related to the temperatures in the grass in winter. The precipitin test is used to investigate predation by Carabidae outside the tussocks in summer. 3 CONTENTS Pare I. INTRODUCTION 7 II.THE HABITAT. 14 SOIL 14 A. 1. General Sampling. 14 2.

The occurrence of Coleoptora in grass tussocks has been well known to beetle collectors for many years, and tussocks as habitats are mentioned in many standard works on beetles (e.g. Joy, 1932; Walsh and Dibb, 1954). Pearce (1948) was the first to suggest that the intert- &orate fauna of grass tussocks might be an interesting ecological study. He gave examples of the number of invertebrates that could occur in a tussock, pointing out that the Coleoptara were one of the best represented orders of insects. As the numbers were highest in the winter, he also suggested that the tussocks might provide shelter from extreme cold, an idea which had been put forward earlier by Hancock (1923) and Holmquist (1926). The possibility of shelter from drought in the summer was also mentioned. Pearce listed the grasses yielding the best results, which were Deschampsia, Dactylis, Cynosurus, Malice, Bromus, Holcus, Molinia, Agrostis and Arrhenatherum. Tussocks of sedge (Juncus species) also contained arthropods, but he considered their fauna to be somewhat diff- erent from those of the grasses. Little quantitative work has been done on the fauna of tussocks as such. Richards (1926), in his survey of the fauna of Oxshott Heath, lists nine species of insect which hibernate in Molinia tufts in winter. Ford (1937, 1938) studied the Collembola of Bromus tussocks near Oxford, and listed other insects which occurred commonly in the sem© habitat. Macfadyen (1952) investigated the Collembola and mites of a Berkshire Molinia fen, containing tussocks of Molinia, Deschampsia and Juncus, and compared the faunas of these three plant species. Duffey (1962), in a paper on the spiders of Wytham Wood, mentions finding a positive correlation between the numbers of litter spiders and tussocks of Nardus at Malham, but omits all details. Data on the Coleoptera of grassland containing tussocks are restricted to surveys of the fauna of the vegetation of arable land, in which no distinction is drawn between the fauna of tuss- ocks and that of the intervening vegetation, or to surveys of soil fauna in which the base of the vegetation was also sampled. A study of the first type was carried out by Cameron (1917) in two meadows in Cheshire; he tried to correlate the insects occurring on and under the surface of the soil with the vegetation, but on too large a scale to give data on indiv- idual tussocks. Ford (1935) listed the invertebrates of a meadow near Oxford, but did not distinguish between the faunas of different plant species. The beetles of a Danish meadow community containing several tussock-forming grasses were sampled by Schj/tz-Christensen (1954), but samples were taken in summer only, and again the vegetation of each sample was not described. Boyd (1960) compared the faunas of grazed prA ungrazod grassland in Argyll, one of the effects of grazing being the prevention of tussock formation. In contrast to the previous surveys, collecting was by pitfall traps, so that species remaining inactive were not collected, and a comparison of the two total faunas was not obtained. Examples of soil surveys which include some of the fauna of the surface vegetation are those of Cameron (1913) near Manchester, Morris (1920) and Buckle (1921) in Cheshire, Morris (1922, 1927) at Rothamsted, Edwards (1929) at Aberystwyth and Salt et. al. (1948) at Cambridge. At the beginning of this study it was decided, therefore, to obtain quantitative data on the species and numbers of beetles occurring in 9 grass tussocks at Silwood Park throughout the year. In order to compare the importance of the plant species to the beetles, three species of tussock wore chosen initially. Those were Dactylis Paomerata L., Deschampsia caespitosa (L.), and Juncus effusus L.; after one month Juncus was omitted, and the two remaining species sampled for a further eight months, after which the study was restricted to Dactylis glomerate L. Most of the data in this thesis relate to this species. The possible shelter from climatic extremes given by tussocks has also received little attention. Ford (1937) made brief measurements of temperature and humidity in Bromus tussocks and suggested that their high humidity was of vital importance to their fauna.

Cook site, off Lawrence Street, York (site code: YORYM 2001.9444) by Harry Kenward, Allan Hall, Deborah Jaques, Kathryn Johnson and John Carrott Summary Archaeological excavations were carried out by York Archaeological Trust at the former D. C. Cook site, off Lawrence Street, York, in May 2001 and February 2003. Plant and invertebrate remains were investigated from three deposits considered worthy of further examination following an assessment. One, from a feature interpreted as a 10th century oven or kiln, yielded modest concentrations of charred cereal grains (mainly barley and oats) showing evidence of sprouting—and probably representing material burnt during drying of grain in the malting process. Two later, medieval, deposits rich in remains preserved by anoxic ‘waterlogging’ were also studied. They came from features interpreted as a barrel well and a ditch. Both gave abundant evidence for natural, semi-natural and artificial habitats in the vicinity, but with some additional evidence of plant food waste (in the ditch). In some respects the assemblage from the ditchfill seemed more typical of a well fill, whilst the well fill was rich in aquatic invertebrates as would be expected from a ditch deposit. Altogether, these remains offered a rare opportunity to examine the environment (and aspects of the economy) of the inhabitants of an area of the city of York well beyond the city walls.

  • And Beetle (Coleoptera) Assemblages in Meadow Steppes of Central European Russia
    15/2 • 2016, 113–132 DOI: 10.1515/hacq-2016-0019 Effect of summer fire on cursorial spider (Aranei) and beetle (Coleoptera) assemblages in meadow steppes of Central European Russia Nina Polchaninova1,*, Mikhail Tsurikov2 & Andrey Atemasov3 Key words: arthropod assemblage, Abstract Galich’ya Gora, meadow steppe, Fire is an important structuring force for grassland ecosystems. Despite increased summer fire. incidents of fire in European steppes, their impact on arthropod communities is still poorly studied. We assessed short-term changes in cursorial beetle and Ključne besede: združba spider assemblages after a summer fire in the meadow steppe in Central European členonožcev, Galičija Gora, Russia. The responses of spider and beetle assemblages to the fire event were travniška stepa, poletni požar. different. In the first post-fire year, the same beetle species dominated burnt and unburnt plots, the alpha-diversity of beetle assemblages was similar, and there were no pronounced changes in the proportions of trophic groups. Beetle species richness and activity density increased in the second post-fire year, while that of the spiders decreased. The spider alpha-diversity was lowest in the first post- fire year, and the main dominants were pioneer species. In the second year, the differences in spider species composition and activity density diminished. The main conclusion of our study is that the large-scale intensive summer fire caused no profound changes in cursorial beetle and spider assemblages of this steppe plot. Mitigation of the fire effect is explained by the small plot area, its location at the edge of the fire site and the presence of adjacent undisturbed habitats with herbaceous vegetation.

  • Atlas of Yorkshire Coleoptera (Vcs 61-65) Part 10 – Cleroidea and Cucujoidea
    Atlas of Yorkshire Coleoptera (VCs 61-65) Part 10 – Cleroidea and Cucujoidea Introduction This section of the atlas deals with the Superfamilies Cleroidea and Cucujoidea, a total of 464 species, of which there are 315 recorded in Yorkshire. Each species in the database is considered and in each case a distribution map representing records on the database (at 1 April 2019) is presented. The number of records on the database for each species is given in the account in the form (a,b,c,d,e) where 'a' to 'e' are the number of records from VC61 to VC65 respectively. These figures include undated records (see comment on undated records in the paragraph below on mapping). As a recorder, I shall continue to use the vice-county recording system, as the county is thereby divided up into manageable, roughly equal, areas for recording purposes. For an explanation of the vice-county recording system, under a system devised in Watson (1883) and subsequently documented by Dandy (1969), Britain was divided into convenient recording areas ("vice-counties"). Thus Yorkshire was divided into vice-counties numbered 61 to 65 inclusive, and notwithstanding fairly recent county boundary reorganisations and changes, the vice-county system remains a constant and convenient one for recording purposes; in the text, reference to “Yorkshire” implies VC61 to VC65 ignoring modern boundary changes. For some species there are many records, and for others only one or two. In cases where there are five species or less full details of the known records are given. Many common species have quite a high proportion of recent records.
