-1 , respectively). S. jeokjo had significantly higher attack ratios (number of attempted captures relative to number of physical contacts between predator and prey) when fed on P. piscicida and S. algicida (18 to 25%) than on L. masanensis (5%). Similarly, successful capture (number of prey ingested relative to number of attempted captures) of P. piscicida and S. algicida (82 to 87%) was significantly higher than that of L. masanensis (2%). L. masanensis may have defensive behavior or chemical protection against predation. However, maximum ingestion rates of Acartia spp. fed on these dinoflagellate species were similar. In understanding the population dynamics and predatorprey interactions of these 3 closely related dinoflagellate species, it is important to distinguish between predation by protists and by copepods.

“…On the other hand, they are generally more restricted to the availability of particular prey types (Tillmann 2004), especially flagellates, than dinoflagellates (Jeong 1999). Therefore, ciliates can respond more rapidly to enhanced food concentrations than dinoflagellates, but their potential of surviving starvation periods is low (Jackson and Berger 1985) compared to dinoflagellates (Hansen 1992;Menden-Deuer et al 2005). Consequently, ciliates can be classified as rapid-reaction ) between the 2.5 years of microzooplankton monitoring (a) and the long-term monitoring (b) food specialists and dinoflagellates more as generalists with longer response times but greater persistence.…”

A monitoring programme for microzooplankton was started at the long-term sampling station ''Kabeltonne'' at Helgoland Roads (54°11.3 0 N; 7°54.0 0 E) in January 2007 in order to provide more detailed knowledge on microzooplankton occurrence, composition and seasonality patterns at this site and to complement the existing plankton data series. Ciliate and dinoflagellate cell concentration and carbon biomass were recorded on a weekly basis. Heterotrophic dinoflagellates were considerably more important in terms of biomass than ciliates, especially during the summer months. However, in early spring, ciliates were the major group of microzooplankton grazers as they responded more quickly to phytoplankton food availability. Mixotrophic dinoflagellates played a secondary role in terms of biomass when compared to heterotrophic species; nevertheless, they made up an intense late summer bloom in 2007. The photosynthetic ciliate Myrionecta rubra bloomed at the end of the sampling period. Due to its high biomass when compared to crustacean plankton especially during the spring bloom, microzooplankton should be regarded as the more important phytoplankton grazer group at Helgoland Roads. Based on these results, analyses of biotic and abiotic factors driving microzooplankton composition and abundance are necessary for a full understanding of this important component of the plankton.

“…On the other hand, dinoflagellates can prey on almost every organic particle present in the oceans (Jeong 1999;Tillmann 2004). Additionally, they have a higher starving potential (Hansen 1992;Menden-Deuer et al 2005), and thus can survive periods of food shortage (Sherr and Sherr 2007). In contrast, ciliates can respond rapidly to enhanced food availability showing growth rates higher than those of dinoflagellates (Strom and Morello 1998) but their potential to survive starvation periods is low (Jackson and Berger 1985;Hansen 1992) and they are more restricted to certain prey items (Tillmann 2004).…”

The role of ciliates, heterotrophic dinoflagellates and copepods in structuring spring plankton communities at Helgoland Roads, North Sea

Mesocosm experiments coupled with dilution grazing experiments were carried out during the phytoplankton spring bloom 2009. The interactions between phytoplankton, microzooplankton and copepods were investigated using natural plankton communities obtained from Helgoland Roads (54°11.3 0 N; 7°54.0 0 E), North Sea. In the absence of mesozooplankton grazers, the microzooplankton rapidly responded to different prey availabilities; this was most pronounced for ciliates such as strombidiids and strobilids. The occurrence of ciliates was strongly dependent on specific prey and abrupt losses in their relative importance with the disappearance of their prey were observed. Thecate and athecate dinoflagellates had a broader food spectrum and slower reaction times compared with ciliates. In general, high microzooplankton potential grazing impacts with an average consumption of 120% of the phytoplankton production (P p ) were measured. Thus, the decline in phytoplankton biomass could be mainly attributed to an intense grazing by microzooplankton. Copepods were less important phytoplankton grazers consuming on average only 47% of P p . Microzooplankton in turn contributed a substantial part to the copepods' diets especially with decreasing quality of phytoplankton food due to nutrient limitation over the course of the bloom. Copepod grazing rates exceeded microzooplankton growth, suggesting their strong top-down control potential on microzooplankton in the field.Selective grazing by microzooplankton was an important factor for stabilising a bloom of less-preferred diatom species in our mesocosms with specific species (Thalassiosira spp., Rhizosolenia spp. and Chaetoceros spp.) dominating the bloom. This study demonstrates the importance of microzooplankton grazers for structuring and controlling phytoplankton spring blooms in temperate waters and the important role of copepods as top-down regulators of microzooplankton.
