A phytobenthos monitoring programme has been carried out in Estonian coastal waters since 1995. Monitoring activities include six sea areas representing different sets of environmental conditions and anthropogenic impact. Methods used in the programme are based on internationally accepted techniques developed for the HELCOM COMBINE programme. During the observation period, the most important events described were the decline of the Fucus vesiculosus population in the northern Gulf of Riga and the Vainameri ar ea, which has triggered several changes in phyto-benthic communities. A new invertebrate species for Estonian coastal waters, Orchestia cavimana, was described in Kudema Bay in 1999. Its population has remained stable since then. In the nearest future the phytobenthos monitoring programme will be reorganized in connection with the implementation of EU WFD in Estonia and the need to include new sea areas in the monitoring activities. Key words: phytobenthos, monitoring, Baltic Sea.","PeriodicalId":250336,"journal":{"name":"Proceedings of the Estonian Academy of Sciences. Biology.

The plants studied can be divided into three groups according to their sensitivity to cytokinins benzyladenine (BA) and kinetin (K). (1) Plants (gerbera cultivars) whose multiplication on BA media is not recommended. Permanent high K level must also be avoided. It must be decreased gradually during a long-term culture. After the 8th or 9th subculture the shoots are to be transferred to the resting medium with 0.1 mg/L K and 1.0 mg/L indoleacetic acid. (2) Plants ( Cordyline, Dracaena, Dieffenbachia) that may be multiplied on media containing either BA or K, the latter being preferable as its concentration may be varied within a larger range (0.5-4 mg/L) without negative side effects. (3) Plants ( Philodendron, Spathiphyllum, Musa) that may be multiplied on BA media without even relatively high BA concentrations (5 mg/L) leading to vitrification. However, in order to obtain the best shoots for rooting, the BA content of the multiplication media has to be reduced to 1/2-1/3 of its original value after the 5th or 6th subculture.","PeriodicalId":250336,"journal":{"name":"Proceedings of the Estonian Academy of Sciences.
