To explore the biogeographic history of Mediterranean/arid plant disjunctions, Old and New World Senecio sect. Senecio were analyzed phylogenetically using nuclear ribosomal DNA sequences (ITS). A clade corresponding to sect. Senecio was strongly supported. Area optimization indicated this clade to be of southern African origin. The Mediterranean and southern African...
Lipids, especially phospholipids, are very common
but important molecules found in cells and animal
tissue, performing many biological functions, particularly
in membranes. Lipids, when mixed with water,
spontaneously form ordered systems, such as micelles,
vesicles and multibilayers. The size of these systems
and their degree of ordering depend on the...
Modern civil commercial transport aircraft provide the means for the safest of all forms of transportation. While advanced computer technology ranging from flight management computers to warning and alerting devices contributed to flight safety significantly, it is undisputed that the flightcrew represents the most frequent primary cause factor in airline...
Growth chamber and field experiments were conducted to investigate
the effects of different temperature levels and durations on
floral induction and vegetative growth in orchardgrass. Propagules
of two clones, XLI-8 (clone R) and MID-5 (clone 0), from the synthetic
variety Pennlate, were used in all experiments.
Clone R plants were...
Before and after the 3-year generic advertising campaign for fresh fish in Denmark, representative consumer
samples were surveyed with regard to their attitudes towards fresh fish, perceived family norms, availability of fresh fish
in shops, meal preparation skills, intentions to buy fresh fish, and actual consumption frequencies. In the pre-campaign...
Effects of age, period and birth cohort on consumption of fat fish, lean fish and processed fish were estimated based on panel data from the Norwegian Women and Seafood Consumption Study (NOWAC). Cohorts selected for the present analysis were women born between 1951 and 1966. Survey questionnaires were mailed to...
In developing countries the framework for institutional engagement in small-scale fishing communities needs to consider the regional, social, economic and environmental complexities of informal resource-based economies. The combination of socio-economic trajectory of artisanal fisherfolks, their relationship with the environment, the economic pressures and the public policy framework, which often regarded...
In this dissertation, I investigate the evolution and genomes of carabid beetles, a worldwide family of over 38,000 species. I focus on two species-rich groups, the tribes Chlaeniini and Bembidiini, both of which are primarily found on the shores of bodies of water. The former are distinctive for their defensive...
