Leaf Area Index of Scandinavian Forests Methods Using in situ and Remotely Sensed Data

This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. The results of the present studies indicate that some methods commonly used as a reference for more complicated methods could result in

Chronic Obstructive Pulmonary Disease (COPD) Epidemiological and Pan-airway Aspects

Background – Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. However, there is little information on the prevalence and particularly on the incidence of COPD. Also, apart from the importance of tobacco smoking and a1-antitrypsin deficiency, information on contributing risk factors for the development of COPD is limited. Hypotheses – 1. Spi

Dynamics of omnivorous crayfish in freshwater ecosystems

In this thesis I examine the dynamics of crayfish in streams and lakes. I have studied the influence of abiotic and biotic factors on abundance, growth, trophic position, niche breadth, and recruitment of crayfish, by conducting field studies, an outdoor channel experiment and timeseries analysis. Overall, the results show that abundance of crayfish is mostly affected by the abundance of predatory
