1. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms
Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER

Sammanfattning : 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.

Sammanfattning : Circadian clocks have been found in numerous cell types and tissues of the body, allowing organisms to coordinate their daily biological functions. They generate cycles of behavioral and physiological processes with a period length of ~24h, which are synchronized to the rotation of the Earth and the subsequent daily changes in illumination, temperature and humidity.

5. Circadian rhythms and carbon acquisition in the red algae Kappaphycus alvarezii and Eucheuma denticulatum
Sammanfattning : Aspects of carbon and nitrogen metabolism have been studied in two closely related tropical red macroalgae (Rhodophyta) that belong to the commercially important genera Kappaphycus and Eucheuma. These algae are cultivated around the world for their carrageenan content. LÄS MER
