  2. 1. Comparative morphological studies of fossil and living plane trees (Platanaceae) and oaks (Quercus): taxonomy, ecology, evolution

    Author : Georg Florian Tschan; Thomas Denk; Ove Eriksson; Bertil Ståhl; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Platanaceae; Platanus; Credneria; Quercus; Galliferae; leaf architecture; epidermal anatomy; comparative morphology; character variation; variability; sample size; diversity patterns; species concepts; ecology; biogeography; evolution; plant fossils; Plant Ecology; växtekologi;

    Abstract : Morphological characters are essential for flowering plant identification, but also provide information about diversity patterns and ecological adaptation. In woody plant species, characters of the leaf are among the most useful and can be examined on fossils as well. READ MORE

  5. 3. Getting to know Trioza apicalis (Homoptera: Psylloidea) – a Specialist Host-Alternating Insect with a Tiny Olfactory System

    Author : Lina Kristoffersen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; Djurs anatomi och morfologi; Entomologi; plant parasitology; Entomology; Ekologi; Ecology; glomeruli; antennal lobe; olfactory receptor neurons electrophysiology; antennae; behaviour; olfaction; Sternorrhyncha; psyllid; Ryggradslösa djurs fysiologi; animal morphology; Animal anatomy; växtparasitologi;

    Abstract : This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. READ MORE

  6. 4. Olfaction in Desert Locusts- Anatomy, Function and Plasticity of the Central Olfactory System

    Author : Rickard Ignell; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hist; serotonin; immunocytochemistry; juvenile hormone; development; olfactometer; intracellular recording; evolution; projection neuron; receptor neuron; antennal lobe; aggregation pheromone; neuroethology; olfaction; Desert locust; Schistocerca gregaria; Ecology; Ekologi; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

    Abstract : The anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. READ MORE

  7. 5. Anatomy of the amphibious liverwort Ricciocarpus natans

    Author : Eva Kronestedt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Levermossor morfologi;

    Abstract : The purpose of the present investigation was to study the structural adaptations in the terrestrial and aquatic life-forms of Ricciocarpus natans and to obtain more information on the ultrastructure and morphogenesis of cells and tissues in this member of the hepatics. Optical and electron (scanning and transmission) microscopy were combined to elucidate various structural aspects. READ MORE
