21. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere
Sammanfattning : Mercury is an element present in the earth crust as well as a component in the atmosphere. During centuries mercury has been released by natural sources, e.g. volcanic eruptions, evasion from water surfaces and degassing from soil. LÄS MER
22. Influence of Sea Surface Temperature on Rainfall and Runof in Northeastern South America: Analysis and Modeling
Sammanfattning : This work represents an amalgam of a group of studies with the purpose of understanding the influence of the Pacific and Atlantic sea surface temperature on precipitation and river discharge in Northeastern South America. Sea surface temperature is a good representative of phenomena such as ENSO that, in turn, cause worldwide climate variability. LÄS MER
23. Functional diversity of zooplankton in marine food webs : Integrating DNA metabarcoding and network modeling
Sammanfattning : The oceans are important regulators of the Earth’s climate system by sequestering carbon from the atmosphere taken up by primary producers. Zooplankton, including protozoans and metazoans of different phyla and size classes, occupies several trophic niches and regulates energy flow between primary producers and fish. LÄS MER
24. Organisation, omvärldssignaler och innovationsförmåga
Sammanfattning : Syftet med denna licentiatavhandling är att undersöka samspelet mellan organisation, omvärldssignaler och innovationsförmåga, samt illustrera detta samspel i en sammanfattande modell.Modellbygget följer omvärldssignalens väg genom organisationen, från vilka signaler som uppmärksammas, över hur organisationen skapar mening kring signalerna, till hur tolkning, strategi och beslut kring omvärldssignalen hanteras.

25. Drivers of Population Dynamics in Bacterioplankton : Spotlight on Alphaproteobacteria and its dominant SAR11 Lineage
Sammanfattning : Bacteria are mediators of biogeochemical cycles and are in this way vital for maintaining life on earth. Their distribution, abundance and functioning are driven by environmental heterogeneity and dynamic change in abiotic and biotic factors. LÄS MER
