  1. 1. Mountain centered icefields in northern Scandinavia

    University dissertation from Stockholm : Institutionen för naturgeografi och kvartärgeologi

    Author : Ola Fredin; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scandinavia; Quaternary; Weichselian; mountain; icefield; ice sheet; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi;

    Abstract : 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.

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

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Reuben Hansman; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oman; Al Hajar; mountain; uplift; orogeny; tectonics; structural; geology; Geology; geologi;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Rasmus Erlandsson; Stockholms universitet.; [2019]
    Keywords : 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;

    Abstract : 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.

  5. 5. The nitrogen economy of mountain birch : As related to environmental conditions and genotype

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Weih; Uppsala universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Betula pubescens ssp. czerepanovii; growth; nitrogen; subarctic; temperature; ultraviolet radiation; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : Responses of mountain birch growth to changed environmental conditions arestrongly affected by birch genotype, and nitrogen economy is a key factor influencingthe winter survival of first-year seedlings. These are some of the findings of a series ofstudies, in which growth, nitrogen economy and winter survival were analysed usingpot-grown seedlings of mountain birch (Betula pubescens ssp. READ MORE
