Spring phytoplankton blooms contribute a substantial part to annual production, support pelagic and benthic secondary production and influence biogeochemical cycles in many temperate aquatic systems. Understanding environmental effects on spring bloom dynamics is important for predicting future climate responses and for managing aquatic systems. We analyzed long-term phytoplankton data from one coastal and one offshore station in the Baltic Sea to uncover trends in timing, composition and size of the spring bloom and its correlations to environmental variables. There was a general trend of earlier phytoplankton blooms by 1–2 weeks over the last 20 years, associated with more sunshine and less windy conditions. High water temperatures were associated with earlier blooms of diatoms and dinoflagellates that dominate the spring bloom, and decreased diatom bloom magnitude. Overall bloom timing, however, was buffered by a temperature and ice related shift in composition from early blooming diatoms to later blooming dinoflagellates and the autotrophic ciliate Mesodinium rubrum. Such counteracting responses to climate change highlight the importance of both general and taxon-specific investigations. We hypothesize that the predicted earlier blooms of diatoms and dinoflagellates as a response to the expected temperature increase in the Baltic Sea might also be counteracted by more clouds and stronger winds. A shift from early blooming and fast sedimenting diatoms to later blooming groups of dinoflagellates and M. rubrum at higher temperatures during the spring period is expected to increase energy transfers to pelagic secondary production and decrease spring bloom inputs to the benthic system, resulting in lower benthic production and reduced oxygen consumption.

The benthic compartment is central to ecosystem services in shelf seas. Assemblages with a higher diversity have been suggested to operate more effectively. However, there is no general ecological relationship between diversity and ecosystem functioning due to species-specific effects and environmental influences. We are taking a trait-based and large-scale observational approach to link patterns in macrofaunal functional diversity with ecosystem functioning in the southern North Sea, a marginal sea of the North Atlantic. Secondary production serves as a quantitative measure of ecosystem functioning. It is calculated with taxon-specific empirical production models, while functional diversity is expressed in indices based on trait dissimilarities. Using spatially implicit regressions, we analyze how secondary production is related to functional diversity and environmental factors. Further, we explore whether models are improved by substituting functional diversity with specific key traits potentially related to secondary production. The North Sea has a long history of cumulating local and global human influences. Knowledge on the predictive value of trait diversity for maintaining productivity in our system is needed for succeeding research on consequences of changes in biodiversity for ecosystem functioning.
