6. Climate Effects on Phytoplankton Biomass and Functional Groups
Sammanfattning : Future climate in temperate regions is projected to get warmer and in many cases wetter. This poses questions about how phytoplankton in our lakes will respond. LÄS MER
7. Latest Miocene – Early Pliocene Paleoclimate and Phytoplankton Productivity
Sammanfattning : Paper IPre-Quaternary paleoclimate studies in Australia mainly focus on terrestrial records from the southeastern part of the continent. IODP Expedition 356 drilled on the northwestern Australian shelf, yielding Miocene-Pleistocene paleoclimate records in an area where climate archives are scarce. LÄS MER
8. Phenotypic evolution and adaptive strategies in marine phytoplankton (Coccolithophores)
Sammanfattning : Coccolithophores are biogeochemically important marine algae that interact with the carbon cycle through photosynthesis (CO2 sink), calcification (CO2 source) and burial of carbon into oceanic sediments. The group is considered susceptible to the ongoing climate perturbations, in particular to ocean acidification, temperature increase and nutrient limitation. LÄS MER
9. The role of freshwater phytoplankton in the global carbon cycle
Sammanfattning : Water flowing through the landscape transports chemical substances including carbon. Along the way from upland soils to the ocean, carbon is transformed from organic carbon into inorganic carbon and vice versa. One such carbon transformation process is the uptake of carbon dioxide (CO2) from the water phase by phytoplankton. LÄS MER
10. Phytoplankton response to a changing climate in lakes in northern Sweden
Sammanfattning : In a climate change perspective, increased air temperatures are already a reality and are expected to increase even more in the future, especially in areas at high latitudes. The present thesis therefore addresses the influence of climate change on the physical properties and the phytoplankton communities of typical small and oligotrophic lakes in northern Sweden (62-64˚N).
