    Abstract : Antennal detection and central nervous integration of behaviourally relevant odours in scarab beetles (Coleoptera: Scarabaeidae) was investigated, using the two Japanese scarabs Anomala cuprea and Phyllopertha diversa (Rutelinae), and the Central African fruit chafer Pachnoda marginata (Cetoniinae) as model species. Electrophysiological single cell recordings in A. READ MORE

  5. 3. Heathlands – A Lost World?

    Author : Mattias Lindholm; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heathland; Calluna vulgaris; Conservation biology; Management; Coleoptera; Carabidae; Lycosidae; Conservation strategy;

    Abstract : Heathland is a familiar landscape type in southwest Sweden. It is open with few trees, and the vegetation is dominated by dwarf-shrubs growing on nutrient-poor soils. Dry heaths with Heather Calluna vulgaris and wet heaths with Bell Heather Erica tetralix are common vegetation communities in the heathland, and they often form mosaics. READ MORE

  6. 4. The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)

    Author : Philip Buckland; Roger Engelmark; Geoffrey Lemdahl; Paul Sinclair; Umeå universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Quaternary geology; environmental archaeology; quaternary science; Coleoptera; beetles; database; environmental reconstructions; climate reconstructions; software; Mutual Climatic Range; MCR; palaeoentomology; Kvartärgeologi; Archaeology; Arkeologi; Archaeology; arkeologi;

    Abstract : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.

  7. 5. Taxonomy, phylogeny, and secondary sexual character evolution of diving beetles, focusing on the genus Acilius

    Author : Johannes Bergsten; Anders N. Nilsson; Jyrki Muona; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; antagonistic coevolution; arms race; sexual conflict; diving beetle; Dytiscidae; Coleoptera; taxon sampling; long-branch attraction; parsimony; Bayesian analysis; taxonomic revision; Biologi; Biology; Biologi;

    Abstract : Sexual conflict can lead to antagonistic coevolution between the sexes, but empirical examples are few. In this thesis secondary sexual characters in diving beetles are interpreted in the light of sexual conflict theory. READ MORE
