Quantitative and Qualitative Investigations of the Invertebrate Fauna under Stones (the Hypolithion) in Some Alpine Habitats at Finse, South Norway. Norsk ent. Tidsskr. 19,1-10. In five alpine habitats (1220-1350 m a.s.\.) at Finse, South Norway, the in­ vertebrate fauna under stones was studied qualitatively and quantitatively during the summers of 1969 and 1970. The stone cover of the ground varied from less than 5% to about 30%, and the majority of stones could be turned by hand. Typical soil animals, and Collembola and Acarina were not col­ lected. The data are compared with quantitative quick trap collections from litter and vegetation between stones in three habitats at Stigstuv (approx. 36 km from Finse, 1210-1240 m a.s.!.). In the comparisons, Oligochaeta. Collembola, and Acarina are excluded. The hypolithic fauna is very rich. containing about the same orders, and to a certain extent the same families. as found in litter and vegetation. In the hypolithic communities, Araneida dominate in number (52-99%), while Araneida never make up as much as 50% of the individuals between stones. The density of invertebrates between stones at Stigstuv may be more than ten times higher than under stones at Finse. However, the density of Araneida under stones was almost as high as between stones. The mean weight of hypolithion ranged from 66 to 157 mg per m2 of stones turned. Araneida seemed to prefer stones that covered about 400 cm2 of the ground. When the energy flow of a habitat is estimated, the hypolithion has to be included. S.

    THE GRANITIC ROCKS OF FARSUND, SOUTH NORWAY ERIC MIDDLEMOST MIDDLEMOST, E.: The granitic rocks of Farsund, South Norway. Norsk Geo/. Tidsskr. 48, pp. 81-99. Oslo 1968. The farsundite is a composite granitic body that crops out over an area of some 420 sq. km. in southern Norway. On a local scale the contact between the farsundite and the surrounding country rocks is often discordant; but when observed on a regional scale a broad structural conformity emerges. Three main facies are found within the farsundite body and the mineralogy and chemistry of these units is discussed. The farsundite is regarded as part of the Rogaland anorthosite province. It was emplaced as a magma that was augmented in volume by the in­ corporation of granitic gneiss. The charnockitic part of the farsundite body is believed to have crystallized under granulite facies conditions at a timl! whenthe main mass of rocks of the Rogaland anorthosite province was cooling down. INTRODUCTION The present study is a reappraisal of the granitic rocks described as farsundite by Barth (in Holtedahl 1960, pp. 41-44). These rocks crop out over an area of approximately 420 sq.km. in south western Vest-Agder, the southern-most county in Norway. Most of the farsundite crops out on a series of peninsulas and islands that are separated from one another by an intricate pattern of fjords. The highest point in the area is at Klåskniben (504 m.) which is 3.5 km east of Orange. The landscape is generally rugged, and it shows consider­ able evidence of ice sculpturing.

  • Distribution of Spiders in Coastal Grey Dunes

The knowledge of dispersal evolution, motivation, its effect on metapopulation dynamics and species distribution at multiple scales is poorly understood and many questions remain unsolved or require empirical verification. In this thesis we contribute to the knowledge of dispersal, by studying both ecological and evolutionary aspects of spider dispersal in fragmented grey dunes. Studies were performed at the individual, population and assemblage level and indicate that behavioural traits narrowly linked to dispersal, con- siderably show [adaptive] variation in function of habitat quality and geometry. Dispersal also determines spider distribution patterns and metapopulation dynamics. Consequently, our results stress the need to integrate knowledge on behavioural ecology within the study of ecological landscapes. / Promotor: Prof. Dr. Eckhart Kuijken [Ghent University & Institute of Nature Dries Bonte Conservation] Co-promotor: Prf.

    Syrphidae (Diptera) of northern Ontario and Akimiski Island, Nunavut: new diversity records, trap analysis, and DNA barcoding A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, Ontario, Canada © Copyright by Kathryn A. Vezsenyi 2019 Environmental and Life Sciences M.Sc Graduate Program May 2019 ABSTRACT Syrphidae (Diptera) of northern Ontario and Akimiski Island, Nunavut: new diversity records, trap analysis, and DNA barcoding Kathryn A. Vezsenyi Syrphids, also known as hover flies (Diptera: Syrphidae) are a diverse and widespread family of flies. Here, we report on their distributions from a previously understudied region, the far north of Ontario, as well as Akimiski Island, Nunavut. I used samples collected through a variety of projects to update known range and provincial records for over a hundred species, bringing into clearer focus the distribution of syrphids throughout this region. I also analysed a previously un-tested trap type for collecting syrphids (Nzi trap), and report on results of DNA analysis for a handful of individuals, which yielded a potential new species. KEYWORDS Syrphidae, Diptera, insects, northern Ontario, Akimiski Island, diversity, insect traps, long term study, range extension, new species, DNA barcoding ii ACKNOWLEDGMENTS This thesis is written in dedication to my co-supervisor David Beresford, without whom none of this would have been possible. You have spent many long hours helping me with my data, my writing, and overall, my life. Your tireless, unwavering belief in me is one of the things that got me to where I am today, and has helped me grow as a person.

  • Hoverflies Family: Syrphidae
    Birmingham & Black Country SPECIES ATLAS SERIES Hoverflies Family: Syrphidae Andy Slater Produced by EcoRecord Introduction Hoverflies are members of the Syrphidae family in the very large insect order Diptera ('true flies'). There are around 283 species of hoverfly found in the British Isles, and 176 of these have been recorded in Birmingham and the Black Country. This atlas contains tetrad maps of all of the species recorded in our area based on records held on the EcoRecord database. The records cover the period up to the end of 2019. Myathropa florea Cover image: Chrysotoxum festivum All illustrations and photos by Andy Slater All maps contain Contains Ordnance Survey data © Crown Copyright and database right 2020 Hoverflies Hoverflies are amongst the most colourful and charismatic insects that you might spot in your garden. They truly can be considered the gardener’s fiend as not only are they important pollinators but the larva of many species also help to control aphids! Great places to spot hoverflies are in flowery meadows on flowers such as knapweed, buttercup, hogweed or yarrow or in gardens on plants such as Canadian goldenrod, hebe or buddleia. Quite a few species are instantly recognisable while the appearance of some other species might make you doubt that it is even a hoverfly… Mimicry Many hoverfly species are excellent mimics of bees and wasps, imitating not only their colouring, but also often their shape and behaviour. Sometimes they do this to fool the bees and wasps so they can enter their nests to lay their eggs. Most species however are probably trying to fool potential predators into thinking that they are a hazardous species with a sting or foul taste, even though they are in fact harmless and perfectly edible.

Diptera, Syrphidae, Abies alba, deadwood, Fagus silvatica, functional diversity, tree-microhabitats, stand heterogeneity Abstract. Hoverflies (Diptera: Syrphidae) provide crucial ecological services and are increasingly used as bioindicators in environ- mental assessment studies. Information is available for a wide range of life history traits at the species level for most Syrphidae but little is recorded about the environmental requirements of forest hoverflies at the stand scale. The aim of this study was to explore whether the structural heterogeneity of a stand influences species richness or abundance of hoverflies in a montane beech-fir forest. We used the catches of Malaise traps set in 2004 and 2007 in three stands in the French Pyrenees, selected to represent a wide range of structural heterogeneity in terms of their vertical structure, tree diversity, deadwood and tree-microhabitats.
