  2. 1. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism

    Author : Jessica Abbott; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; embryologi; ontogeni; animal morphology; embryology; Utvecklingsbiologi; Damselflies; Colour polymorphism; Development; Frequency-dependence; Morphology; growth animal ; ontogeny; Animal anatomy; Development biology; Djurs anatomi och morfologi; Population divergence; Animal ecology; Djurekologi;

    Abstract : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations.

  4. 2. Evolution and Development of the Onychophoran Head and Nervous System

    Author : Joakim Eriksson; Graham Budd; John Peel; Gerhard Scholtz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Onychophora; Development; Nervous System; Immunohistochemistry; Gene Expression; Biologi; Biology; Biologi; zoologisk utvecklingsbiologi; Animal Development;

    Abstract : Onychophorans are closely allied to the arthropods and possess a body organisation more similar to Middle Cambrian fossils than to recent arthropods. This means that onychophorans in some respects can be regarded as a model for the last common ancestor to both the Arthropoda and the Onychophora. READ MORE

  5. 3. Becoming Wilderness : a topological study of Tarangire, Northern Tanzania 1890-2004

    Author : Camilla Årlin; Mats Widgren; Dan Brockington; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tanzania; Tarangire National Park; game reserve; topology; political ecology; landscape; tsetse; Mbugwe; Gorowa; conservation; man-animal networks; Human geography; Kulturgeografi; kulturgeografi; Human Geography;

    Abstract : Based on field and archival research, Becoming Wilderness analyses the fluid constructs of game preservation and their affect within networks and landscapes to the west of Tarangire National Park, Northern Tanzania from the late 19th Century until the present. The initial query of this thesis is how and why Tarangire comes to be separated as different from its surrounding (on the map and within policy) and what this has entailed for what is ‘within’ and ‘outside’.

  6. 4. Morality Beyond Humanity : Schopenhauer, Grysanowski, and Schweitzer on Animal Ethics

    Author : Monica Libell; Avdelningen för idé- och lärdomshistoria; []
    Keywords : HUMANIORA; HUMANITIES; Djurs etologi och psykologi; Animal ethology and psychology; Morallära; Moral science; Vetenskapshistoria; History of science; history of medicine; antivivisection; Schweitzer; Grysanowski; Schopenhauer; Germany; animal rights; animal ethics; animal welfare;

    Abstract : The study examines the character and development of the animal ethical ideas of three German thinkers: Arthur Schopenhauer, Ernst Grysanowski, and Albert Schweitzer. By situating them in their cultural and intellectual context, the study explores the differing meanings of their ethical views of animals and seeks to answer the question of how their ideas can be explained historically.

  7. 5. Laminins and alpha11 integrin in the human eye : importance in development and disease

    Author : Berit Byström; Fatima Pedrosa Domellöf; Ulf Stenevi; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; basement membranes; extracellular matrix; laminin; integrin; cornea; development; keratoconus; wound healing; remodeling; immunohistochemistry; Ophtalmiatrics; Oftalmiatrik;

    Abstract : The extracellular matrix (ECM) offers a protective shelter for cells and provides signaling paths important for cell to cell communication. ECM consists of basement membranes (BM) and interstitial matrix. BMs provide mechanical support for parenchymal cells, influence cell proliferation, survival, migration and differentiation. READ MORE
