   Sammanfattning : This dissertation is on argumentative strategies based on authority. In its first half, three of the most elaborate and influential approaches in argumentation theory, related to the models developed in this work, are analyzed: Douglas Walton's dialectical frame for analysis of arguments from expert opinion; Frans van Eemeren and Peter Houtlosser's pragma-dialectical approach to strategic maneuvering in argumentation; the concept of strategy used in Else Barth and Erik Krabbe's formal dialectics.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; floodwater mosquitoes; mosquito control; predation; aquatic insects;

   Sammanfattning : Long-term insect abundances have been studied to investigate factors structuring the insect communities of the temporary wetlands around the River Dalälven floodplain. In the wet meadows and swamps in the River Dalälven floodplains recurrent floods are the ultimate prerequisite for high production of floodwater mosquitoes. LÄS MER
