11. Towards CO2 efficient centralised distribution
Sammanfattning : This dissertation treats a topic that has received increasing attention as of late, namely that of the environment and in particular increasing levels of CO2 emissions caused by transport. The aim of the dissertation is to explain how a shipper, through various measures, can reduce transport-related CO2 emissions when centralising a distribution system and how this affects the provision of cost efficient customer service.

12. Phenotypic plasticity and local adaptation in tadpoles
Sammanfattning : Amphibian larvae are plastic in many traits. Can plasticity buffer population divergence, so that local adaptation is more common in non-plastic traits? I argue that this may be the case for adaptive plastic responses. LÄS MER
13. Adaptation Along Environmental Gradients: an Evaluation of Physiological Mechanisms and Ecological Constraints
Sammanfattning : For ectotherms living in seasonal environments, time available for development and growth is often constrained by the length of the growth season. Declining season length towards higher latitudes often select for latitudinal clines in development and growth rates, exhibiting increasing growth and developmental rates towards the north. LÄS MER
14. Effects of Habitat Quality on Behavioural Decisions and Population Dynamics in the Siberian Jay
Sammanfattning : The dynamics of natural populations may be influenced by a variety of factors, ranging from feeding interference and territoriality to the risk of predation and climatic effects. The relative influence of these factors may be contingent upon the quality of the habitat in which individuals reside. LÄS MER
