  2. 2. The role of inland waters in the carbon cycle at high latitudes

    Author : Erik Lundin; Jan Karlsson; Reiner Giesler; Robert Striegl; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; lakes; streams; carbon C ; carbon dioxide CO2 ; methane CH4 ; dissolved inorganic carbon DIC ; boreal; sub-arctic; arctic; emission; sediments; burial; budget; limnologi; Limnology; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys; naturgeografi; Physical Geography;

    Abstract : Understanding the drivers of climate change requires knowledge about the global carbon (C) cycle. Although inland waters play an important role in the C cycle by emitting and burying C, streams and lakes are in general overlooked in bottom-up approached C budgets. READ MORE

  3. 3. Holocene climate change in high latitudes recorded by stable isotopes in peat

    Author : Päivi Kaislahti Tillman; Steffen Holzkämper; Stefan Wastegård; Peter Kuhry; Mats Rundgren; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; -; Quaternary geology; Kvartärgeologi; Quarternary Geology; kvartärgeologi;

    Abstract : A key to the understanding of natural and human induced climate variations is to reconstruct past changes from different environments. No outstanding method for general use has been pinpointed, instead, a need of multi-proxy studies is often stressed and the reconstructions are under constant improvement by new techniques.

  4. 4. Performance of forage maize at high latitudes : plant development, agronomy and nutritive value

    Author : Zohaib Mussadiq; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Following the development of earlier maturing hybrids the cultivation of forage maize (Zea mays L.) in Northern Europe has markedly increased in recent decades. This has raised needs for greater knowledge regarding the performance of forage maize in marginal areas, such as Sweden, under current conditions. READ MORE

  5. 5. Magnetic orientation in migratory birds

    Author : Rachel Muheim; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; Djurekologi; cue-conflict; clock-shift; cue calibration; geomagnetic field; high Arctic latitudes; Emlen funnel; magnetic compass; magnetoreception; navigation; migration; bird; orientation;

    Abstract : My thesis focuses on magnetic orientation in migratory birds, i.e. how they can perceive information from the Earth’s magnetic field and use it for orientation. READ MORE
