  1. 1. Soil salinity as a driver of microbial community structure and functioning

    Author : Kristin Rath; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

  2. 2. From geography to genes: evolutionary perspectives on salinity tolerance in the brackish water barnacle Balanus improvisus

    Author : Anna-Lisa Wrange; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : environmental change; salinity; marine; invertebrates; evolution; plasticity; population genetics; functional genomics; barnacle; osmoregulation;

    Abstract : How species respond to changes in their environment is a fundamental question in biology. This has become an increasingly important issue as anthropogenic effects of climate change and biological invasions have major impacts on marine ecosystems worldwide. READ MORE

  3. 3. Ecological drivers and genetic signatures of evolutionary divergence and local adaptation in pike (Esox lucius)

    Author : Johanna Sunde; Anders Forsman; Anssi Laurila; Linnéuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; adaptation; differentiation; Esox lucius; evolution; gene flow; genetic admixture; genetic structure; microsatellites; pike; RADseq; salinity tolerance; temperature tolerance; Ecology; Ekologi;

    Abstract : The diversity among species, populations, and individuals in nature is astonishing. Genetic and phenotypic variation constitutes the raw material for evolution. It influences how populations respond to changing environments, and can impact long-term survival of species and ecosystem functioning. READ MORE

  4. 4. Molecular and Metabolic Aspects of Plant and Bacterial Salt Tolerance

    Author : Peter Olsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknik; metabolism; gamma-aminobutyric acid; Nicotiana tabacum; salinity; hypoxia; heamoglobin; microarray; glycine betaine; NaCl; GABA; Vitreoscilla; calmodulin; Esherichia coli; tobacco; Biokemi; Metabolism; Biochemistry; Arabidopsis;

    Abstract : Salt stress is one of the historically as well as potentially largest agriculture problem humans have faced. Researchers have investigated and tried to solve this problem for a long time. Over 20 reviews have been written on this topic the last five years. READ MORE

  5. 5. Macroalgae in the Baltic Sea : responses to low salinity and nutrient enrichment in Ceramium and Fucus

    Author : Lena Bergström; Lars Ericson; Lena Kautsky; Erik Bonsdorff; Christine A Maggs; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology; adaptation; asexual reproduction; Baltic Sea; Gulf of Bothnia; salinity; macroalgae; nutrients; sexual reproduction; stress; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The brackish Baltic Sea is a marginal environment for both marine and freshwater species. The rate of ecological differentiation is presumably high due to strong selection pressure from a gradient of decreasing salinity that has been present in its current state for only about 3 000 years.
