1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.
