  1. 1. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Andersson; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

    Abstract : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.

  2. 2. Inference of functional association networks and gene orthology

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Thomas Schmitt; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; orthology; InParanoid; FunCoup; systems biology; biological networks; network inference; functional coupling; functional association; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Abstract : Most proteomics and genomics experiments are performed on a small set of well-studied model organisms and their results are generalized to other species. This is possible because all species are evolutionarily related. When transferring information across species, orthologs are the most likely candidates for functional equivalence. READ MORE

  3. 3. Species community structure and functional redundancy in Swedish headwater streams

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Emma Göthe; Sveriges lantbruksuniversitet.; [2013]

    Abstract : Streams and rivers only contain a small proportion of the Earth's freshwater, but nevertheless harbour much biodiversity. Headwater streams are the most prevalent running water environments, but despite their wide distribution, they are often excluded from important freshwater legislation and national monitoring programmes.

  4. 4. Biodiversity and Species Extinctions in Model Food Webs

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Charlotte Borrvall; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; food webs; redundancy; relaxation time; stability; stochasticity; species deletion; species extinction; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Many of the earth’s ecosystems are experiencing large species losses due to human impacts such as habitat destruction and fragmentation, climate change, species invasions, pollution, and overfishing. Due to the complex interactions between species in food webs the extinction of one species could lead to a cascade of further extinctions and hence cause dramatic changes in species composition and ecosystem processes.

  5. 5. Food Webs, Models and Species Extinctions in a Stochastic Environment

    University dissertation from Ekologiska institutionen, Lunds universitet

    Author : Patrik Karlsson; Lunds universitet.; Lund University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; functional redundancy; trophospecies; species aggregation; environmental stochasticity; interaction strength; spectral colour; food web structure; food webs; extinction risk;

    Abstract : In light of the current global mass extinction of species, ecologists are facing great challenges. In order to reverse the path towards additional extinctions early warning systems to guide management actions need to be developed. READ MORE
