1. 1. Development and maintenance of quality indicators in pheasants

   Författare :Thomas Ohlsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PHA; ELISA; immunocompetence; carotenoid coloration; male ornaments; fluctuating asymmetry; growth; early development; Phasianus colchicus; egg size; sexual selection; Animal ecology; Djurekologi; Ecology; Ekologi;

   Sammanfattning : Females often base their choice of mates on the expression, size or intensity, of male sexual ornaments. Indicator models of sexual selection assume that females assess male genetic quality through the expression of these secondary sexual characters. LÄS MER

3. 2. Ecology across Boundaries : Food web coupling among and within ecosystems

   Författare :Pia Bartels; Peter Eklöv; Lars J. Tranvik; Daniel E. Schindler; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cross-ecosystem; food web; habitat coupling; terrestrial-aquatic linkages; subsidy; allochthonous; lake ecosystem; population divergence; trait variation; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

   Sammanfattning : Cross-boundary movements of energy and material are ubiquitous. Freshwater ecosystems receive nutrients, dissolved, and particulate organic matter from adjacent terrestrial ecosystems, whereas terrestrial ecosystems mainly receive prey organisms and detritus deposited by physical processes such as floods from freshwater ecosystems.

4. 3. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism

   Författare :Jessica Abbott; Biologiska institutionen; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 4. Molecular methods for microbial ecology : Developments, applications and results

   Författare :Lucas Sinclair; Alexander Eiler; Josh Neufeld; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; microbiology; metagenomics; ecology; metabolism; Bioinformatik; Bioinformatics;

   Sammanfattning : Recent developments in DNA sequencing technology allow the study of microbial ecology at unmatched detail. To fully embrace this revolution, an important avenue of research is the development of bioinformatic tools that enable scientists to leverage and manipulate the exceedingly large amounts of data produced.

7. 5. Structure and Function of Odorant Binding Proteins and Chemosensory Proteins in Moths

   Författare :Severine Jansen; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR structure; Ecology; Ekologi; Development; Lepidoptera; Odorant Binding Proteins; Chemosensory Proteins;

   Sammanfattning : Odorant Binding Proteins (OBPs) and Chemosensory Proteins (CSPs) are small soluble proteins found in the lymph of insect sensillae located on insect antennae. Odorant Binding proteins are implied in olfaction, by binding hydrophobic odorant molecules and transporting them to the olfactory receptor located on the dendrite of the olfactory neurons. LÄS MER
