2. 1. Brain Aromatase in the guppy, Poecilia reticulata : Distribution, control and role in behaviour

   Author : Stefan Hallgren; Håkan Olsén; Bertil Borg; Julie Bakker; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oestrogen production; behaviour; anatomy; endocrinology; bio markers; endocrine disruption; Organism biology; Organismbiologi; funktionell morfologi; Functional Zoomorphology; Biology;

   Abstract : Oestrogens are produced by aromatisation of androgens by the aromatase enzyme. In the vertebrate brain this synthesis has vital functions in nerve protection, cell proliferation and nerve development during injury respectively brain development. READ MORE

   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
