1. Thermal plasticity and limitations in tropical trees
Sammanfattning : Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate close to their thermal limits because of a historically and seasonally stable environment. LÄS MER
2. Baltic Sea phytoplankton in a changing environment
Sammanfattning : Future climate scenarios in the Baltic Sea project increasing sea surface temperature, as well as increasing precipitation and river runoff resulting in decreased salinity. These changes can severely impact the dynamics and function of brackish water communities, specifically phytoplankton. LÄS MER
3. Secondary succession in tropical dry forests : drivers and mechanisms of forest regeneration
Sammanfattning : Secondary succession is a complex process involving numerous factors acting across scales. Understanding secondary succession in tropical dry forests is important for the conservation and restoration of this highly threatened biome. LÄS MER
4. Ecology of lichens in boreal coniferous forests with reference to spatial and temporal patterns
Sammanfattning : The thesis deals with the ecology of lichens in two contrasting types of forest, epiphytic lichens in old Picea abies forest of the fi re-refugia type and epigeic as well as epixylic lichens in a successional sequence of fire- susceptible Pinus sylvestris forests. Results in five separate papers form the basis for a discussion of general patterns of dispersal, succession and life strategies in lichens. LÄS MER
5. Bacterioplankton population dynamics in a changing ocean
Sammanfattning : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.
