  1. 1. Mountain centered icefields in northern Scandinavia

    Författare :Ola Fredin; Clas Hättestrand; Arjen Stroeven; Peter Jansson; Johan Kleman; Jon Landvik; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scandinavia; Quaternary; Weichselian; mountain; icefield; ice sheet; Physical geography; Naturgeografi;

    Sammanfattning : Mountain centered glaciers have played a major role throughout the last three million years in the Scandinavian mountains. The climatic extremes, like the present warm interglacial or cold glacial maxima, are very short-lived compared to the periods of intermediate climate conditions, characterized by the persistence of mountain based glaciers and ice fields of regional size.

  3. 2. Constraining the Uplift History of the Al Hajar Mountains, Oman

    Författare :Reuben Hansman; Uwe Ring; Victoria Pease; Hemin Koyi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oman; Al Hajar; mountain; uplift; orogeny; tectonics; structural; geology; Geology; geologi;

    Sammanfattning : Mountain building is the result of large compressional forces in the Earth’s crust where two tectonic plates collide. This is why mountains only form at plate boundaries, of which the Al Hajar Mountains in Oman and the United Arab Emirates is thought to be an example of. LÄS MER

  5. 4. Spatial and temporal population dynamics in the mountain tundra – mesopredator and prey

    Författare :Rasmus Erlandsson; Anders Angerbjörn; Dennis Murray; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population dynamics; cyclic; mountain tundra; arctic fox; Norwegian lemming; small rodents; mesopredator; predation; survival; reproduction; zoologisk ekologi; Animal Ecology;

    Sammanfattning : It is well known that competition, predation and fluctuating food resources can have strong effect on individual fitness and population dynamics. The complexity of natural systems can make it complicate to disentangle those processes, but environments with relatively simple food webs, and strong cyclic population dynamics offer contrasting conditions resembling experimental treatments.
