Patterns in vegetation can be expressed through the variation in species composition between plots, which has been termed ‘beta-diversity’ by Whittaker (1960, 1972). The general importance of beta-diversity has been emphasized in recent years (e.g. Gering et al., 2003; Olden et al., 2006; Sax and Gaines 2003; Srivastava 2002). However, even though Legendre et al., (2005) postulate that “beta di...

This study correlated an art therapy descriptive technique originally applied to adolescent burn victims with adult combat-related victims in an effort to identify art themes and graphic elements associated with post-traumatic stress disorder. The designed rating instrument, referred to as the Combat Trauma Art Therapy Scale (CTATS), consisted of 62 items aimed to detect common themes associate...

I thank my advisor Yngvar Berg for accepting me as one of his students, and so making this work possible, and for introducing me to the very interesting field of neural computation. I will also thank him for being encouraging, and allowing me a great freedom in choice of methods and solutions. Many thanks to Tor Sverre Lande as well, for his constructive critisism of circuit implementations. Co...

— The interaction between the conduction electrons and the localized 4f-electrons in TmSb has been investigated by measuring the temperature variation in the electrical resistivity. It is shown that the scattering by the 4f-quadrupole charge distribution in Tm gives a contribution to the resistivity of the same order of magnitude as the usual exchange scattering processes. Good agreement is obt...

Understanding population responses to novel environments is a central concern of both evolutionary biology and ecology (Maynard Smith 1989; Bradshaw 1991; Hoffman and Parsons 1991; Peters and Lovejoy 1992; Kareiva et al. 1993). Populations subject to substantial environmental stress, such as occurs during colonization attempts, human-mediated introductions or reintroductions, orglobal climatic ...

Acknowledgments The lion's share of the results reported on in this thesis has been achieved within OBASCO project atÉcole des Mines de Nantes, to a large part by means of different collaborations involving almost all of my colleagues there. These are acknowledged in the text, as some cooperations with other researchers, as the corresponding work is presented. Here, I would just like to express...
