  2. 21. Food webs and the distribution of body sizes

    Author : Tomas Jonsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Many ecologically relevant life-history traits of organisms, (such as generation time and ingestion rate) are significantly correlated to body size. Since these individual and species characteristics can affect the interactions between the species in a community, it is possible that the distribution of body sizes (in communities) can affect different properties of foodwebs as well.

  4. 22. Applying emerging genetic methods to wild model systems

    Author : Ida-Maria Blåhed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Genetic material is an invaluable source of information for assessments of wild populations. By using information derived from genetic markers, individuals can be identified and tracked over time, enabling studies of a wide range of behavioral, ecological, and evolutionary processes.

  5. 23. Plant species diversity patterns in a Swedish rural landscape : effects of the past and consequences for the future

    Author : Sara A. O. Cousins; Roy Haines-Young; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plant species richness in rural landscapes is threatened as grassland management ceases or changes, and as many remaining semi-natural grasslands are becoming increasingly fragmented. This thesis is a study of plant species diversity in a rural landscape in south-eastern Sweden, and its relationship to management history and landscape pattern. READ MORE

  6. 24. Dynamic Modeling of Nitrifying Trickling Filters

    Author : Torsten Wik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed parameter system; Trickling Filter; Biofilm; Process Model; Experiments; Wastewater; Dynamics;

    Abstract : Trickling filters, one kind of biofilm reactors, for removal of nitrogen in municipal wastewater are presently increasing in number in Sweden. For improved control and operation of wastewater treatment plants, where such reactors are used, dynamic models describing their behavior are necessary. READ MORE

  7. 25. Statistical Methods for Taxon Classification and Bird Migration Phenology

    Author : Måns Karlsson; Ola Hössjer; Jonas Knape; Benjamin Bolker; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Classification; quantile regression; phenology; statistical ornithology; L-functionals; set-valued classification; species identification; statistical ecology; multispecies modelling; matematisk statistik; Mathematical Statistics;

    Abstract : The connection between ecology and statistics is deep. Methodological advancement in statistics open up new possibilities to understand the distribution of life on earth, and research questions in ecology cause new statistical methods to be developed. READ MORE
