EcolChange seminar (21st October, Thursday): Kalle Olli about the alpha and beta diversity of phytoplankton communities in the Helsinki Archipelago

Seminar of Department of Botany and Centre of Excellence EcolChange

Speaker: Prof. Kalle Olli (Estonian University of Life Sciences/ University of Tartu)

Title of the talk: Trends in alpha and beta diversity of phytoplankton communities in the Helsinki Archipelago, the Baltic Sea

Time: Thursday, 21 October 2021 at 14.15

Place: Tartu, Lai 40-218 (mandatory to present a covid certificate or to wear a mask), or virtual seminar in Zoom

Summary: Helsinki City has possibly the best phytoplankton community time-series in the Baltic Sea.  We witness a conspicous temporal change in community composition and increas in species richness over half a century. Temporal beta trend reflects the notorious eutrophication history of the area, while spatial beta trends suggest progressing homogenisation in time.
