چکیده
Climate change is driving Baltic Sea shifts, with predictions for decrease in salinity and increase temperature light limitation. Understanding the responses of spring phytoplankton community to these shifts essential assess potential changes biogeochemical cycles functioning. In this study we use a high-throughput well-plate setup experimentally define growth acquisition traits over gradients salinity, irradiance three dinoflagellates commonly occurring during Sea, Apocalathium malmogiense , Gymnodinium corollarium Heterocapsa arctica subsp. frigida . By analysing response cell volume, growth, light-acquisition gradients, showed that each have their own niches preferences are affected differently by small temperature. A. has more generalist strategy, its being less temperature, comparison other tested dinoflagellates, G. sensitive higher intensities. On hand, seem be than those H. We contextualized our experimental findings using data collected on ships-of-opportunity between 1993-2011 natural Sea. The complex were mostly found temperatures<10°C salinities 4-10 ‰, matching used experiments. Our results illustrate trait information can complement monitoring observations, providing powerful tools answer questions related species’ capacity adapt compete under changing environment.

Decadal-Scale Changes of Dinoflagellates and Diatoms in the Anomalous Baltic Sea Spring Bloom
The algal spring bloom in the Baltic Sea represents an anomaly from the winter-spring bloom patterns worldwide in terms of frequent and recurring dominance of dinoflagellates over diatoms. Analysis of approximately 3500 spring bloom samples from the Baltic Sea monitoring programs revealed (i) that within the major basins the proportion of dinoflagellates varied from 0.1 (Kattegat) to >0.8 (cent...
متن کاملLife-history responses to changing temperature and salinity of the Baltic Sea copepod Eurytemora affinis
To understand the effects of predicted warming and changing salinity of marine ecosystems, it is important to have a good knowledge of species vulnerability and their capacity to adapt to environmental changes. In spring and autumn of 2014, we conducted common garden experiments to investigate how different populations of the copepod Eurytemora affinis from the Baltic Sea respond to varying tem...
متن کاملStudy of Temperature and Salinity Inversions in the Oman Sea
In this research, observational data are analyzed to explain temperature and salinity inversions and double diffusion in the Oman Sea. The results of this paper show that intrusive structures extend over a depth of about 100-450 meters in the Oman Sea. Temperature and salinity inversions observed depth of 250 m in winter and summer in the Oman Sea. Steps thickness is about 10 to 20 meters. A wa...
