  1. 1. Breaking the ice : effects of ice formation and winter floods on vegetation along streams

    Author : Lovisa Lind; Christer Nilsson; Christine Weber; Michael Scott; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anchor ice; climate change; in-stream; riparian; river ice; streams; vegetation;

    Abstract : Streams in cold regions are characterized by unique hydrological processes that control flow regime and water levels. One of the most important processes is the formation, growth and melting of different types of ice in and around the stream channel during winter. READ MORE

  2. 2. Dead-Ice Under Different Climate Conditions: Processes, Landforms, Sediments and Melt Rates in Iceland and Svalbard

    Author : Anders Schomacker; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; klimatologi; glacier; dead-ice; surge; ice-cored; Little Ice Age; fysisk geografi; Geologi; Geology; Svalbard; Iceland; Sedimentology; cartography; pedology; geomorphology; Sedimentologi; Physical geography; geomorfologi; marklära; kartografi; climatology;

    Abstract : Modern dead-ice environments in the glacier forefields of Brúarjökull, Iceland and Holmströmbreen, Svalbard were investigated with focus on landform and sediment genesis, as well as quantification of melting. Field monitoring and studies of multi-temporal aerial photographs, satellite imagery, and Digital Elevation Models (DEMs) provided data for the melting quantification. READ MORE

  3. 3. Geophysical Applications of Vegetation Modeling

    Author : Jed O Kaplan; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Växtbiokemi; Plant biochemistry; CH4; CO2; stable isotopes; carbon cycle; wetland; ice core; methane; Holocene; mammoths; tundra; ice age; LGM; biogeography; biome; biogeochemistry; Vegetation model; Miljökemi; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Abstract : This thesis describes the development and selected applications of a global vegetation model, BIOME4. The model is applied to problems in high-latitude vegetation distribution and climate, trace gas production, and isotope biogeochemistry. READ MORE

  4. 4. Gender and physiology in ice hockey : a multidimensional study

    Author : Kajsa Gilenstam; Karin Henriksson-Larsén; Kim Thorsen; Staffan Karp; Carl Johan Sundberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; physiology; gender; sports medicine; ice hockey; women s sport; athletic performance; social conditions; qualitative method; quantitative method; exercise tests; Sports; Idrott; Gender studies; Genus; Physiology; fysiologi;

    Abstract : Background That men are prioritised over women has been called the “gender regime in sport”, and has in part been explained by the gender difference in performance. However, gender differences in physical performance between women and men can be debated to depend on how comparisons are made and on the fact that there are many different confounders that may influence the results.

  5. 5. Solar Activity Changes at the End of the Last Ice Age - Influences on Climate and Applications for Dating

    Author : Florian Adolphi; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solar Activity; 10Be; 14C; radiocarbon calibration; time scale; geochronology; paleoclimate; ice cores; tree rings; IntCal; cosmogenic radionuclides;

    Abstract : Throughout its history Earth experienced a variety of natural climate changes. By investigating their spatial and temporal evolution we can increase the understanding of the mechanisms and dynamics underlying natural climate change and improve our general comprehension of the climate system.
