    Abstract : Conservation laws play an important role in science. The aim of this thesis is to provide an overview and develop new methods for constructing conservation laws using Lie group theory. The derivation of conservation laws for invariant variational problems is based on Noether’s theorem. READ MORE

  2. 2. Population genetic analyses in the orchid genus Gymnadenia a conservation genetic perspective

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Susanne Gustafsson; Uppsala universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Genetic engineering; Orchidaceae; Gymnadenia; conservation; microsatellites; genetic structure; mating pattern; Genteknik; TECHNOLOGY Bioengineering Genetic engineering including functional genomics; TEKNIKVETENSKAP Bioteknik Genteknik inkl. funktionsgenomik; naturvårdsbiologi; Conservation Biology;

    Abstract : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. READ MORE
