  • Lifespan extension in a semelparous chordate occurs via developmental growth arrest just prior to meiotic entry 

    Subramaniam, Gunasekaran; Campsteijn, Coen; Thompson, Eric (PLoS, 2014-04-02)
    It is proposed that the ageing process is linked to signaling from the germline such that the rate of ageing can be adjusted to the state of the reproductive system, allowing these two processes to co-evolve. Mechanistic ...

    Subramaniam, Gunasekaran (The University of Bergen, 2015-05-22)
    All living organisms experience ageing during the course of their lifespan. The science of ageing has emerged into an enthralling area of research. Our knowledge of the mechanisms of ageing and reproduction has been mainly ...

  • Limited male incubation ability and the evolution of egg size in shorebirds 

    Lislevand, Terje; Thomas, Gavin H. (The Royal Society, 2006-06-22)
    In bird species where males incubate but are smaller than females, egg size may be constrained by male body size, and hence ability to incubate the eggs. Using data from 71 such shorebird species, we show that egg size ...

  • The lineage-specific evolution of aquaporin gene clusters facilitated tetrapod terrestrial adaptation 

    Finn, Roderick Nigel; Chauvigné, Francois; Hlidberg, Jón Baldur; Cutler, Christopher P.; Cerdà, Joan (Public Library of Science, 2014-11-26)
    A major physiological barrier for aquatic organisms adapting to terrestrial life is dessication in the aerial environment. This barrier was nevertheless overcome by the Devonian ancestors of extant Tetrapoda, but the origin ...

  • Linear and Nonlinear Convection in Porous Media between Coaxial Cylinders 

    Bringedal, Carina (The University of Bergen, 2011-05-02)
    In this thesis we develop a mathematical model for describing three-dimensional natural convection in porous media filling a vertical annular cylinder. We apply a linear stability analysis to determine the onset of convection ...

  • Linear dependencies between non-uniform distributions in DES 

    Fauskanger, Stian (The University of Bergen, 2014-05-30)
    Davies and Murphy explained some non-uniform distributions of the output from pairs and triplets of S-boxes in DES, and how they are completely dependent on some key bits. There are linear dependencies between these ...

  • The linear stationary wave response to Arctic amplification related heating 

    Sellevold, Raymond (The University of Bergen, 2015-06-01)
    There has been a raft of manuscripts which claim to show that Arctic amplification (AA) is responsible for changes in the large-scale wintertime midlatitude atmospheric circulation. Responses to these studies have shown ...

  • Lineshape Models in Inner-shell Photoelectron Spectra of Free Molecules and Clusters 

    Abu-samha, Mahmoud (The University of Bergen, 2006-09-22)
    Investigating the nature of molecules and clusters is of paramount importance for our understanding of the composition and the properties of matter. X-ray photoelectron spectroscopy is one of the most powerful techniques ...

  • Linking Northern High-Latitude Cryospheric Changes to Large-Scale Atmospheric Circulation 

    Knudsen, Erlend Moster (The University of Bergen, 2015-03-20)
    Warming twice as fast as the rest of the globe, the northern high-latitudes arguably show the clearest evidences of observed and projected climate changes. Two of these are the rapid loss of Arctic sea ice and the shrinking ...

  • Local Likelihood 

    Otneim, Håkon (The University of Bergen, 2012-04-23)
