1. The rhythm of adolescence : morningness-eveningness and adjustment from a developmental perspective
Abstract : In recent developmental research, sleep-wake patterns and preferences, in other words Morningness-Eveningness, have been shown to be related to various kinds of problem behavior. Previous research on adolescents has demonstrated that individuals with a sleep-wake preference toward staying up late in the evening and arising late in the morning (i.e. READ MORE

2. Circadian Rhythms in Moth Sex Pheromone Communication
Abstract : Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephestia kuehniella.

3. Interference with biological rhythm : a novel approach to metabolic disorders in women
Abstract : Women seem to be largely protected against certain ‘welfare disorders’ such as cardiovacular disease and osteoporosis, during their fertile years.The metabolic changes observed during women’s non-menstrual states, i.e. READ MORE

4. Studies on Natural Variation and Evolution of Photoperiodism in Plants
Abstract : Photoperiodism refers to the organism’s ability to detect and respond to seasonal changes in the daily duration of light and dark and thus constitutes one of the most significant and complex examples of the interaction between the organism and its environment. This thesis attempts to describe the prevalence of variation in a photoperiodic response, its adaptive value, and its putative genetic basis in a common cruciferous weed, Capsella bursa-pastoris (Brassicaceae).

5. Biological Rhythms of Pancreatic Secretion in Young Pigs with empahasis to the time around weaning
Abstract : When the time structure (chronome) of pancreatic secretion was studied after weaning in 5-week-old pigs, the zero-amplitude (no-rhythm) assumption was rejected for the about-weekly (circaseptan, CS) and about-half-weekly (circasemiseptan, CSS) chronome components. When the data were assessed individually on a day-to-day basis, a 24-hour component was suggested (P. READ MORE
