“…One is that Lake Baikal does not fit the features of the B-habitat; the second is that this species is growing under fairly unusual environmental conditions: it is kept in suspension by convectional currents under thick ice cover (Kozhov, 1963). Such species (including Stephanocostis chantaicus, Scheffler & Padisák, 2000) would deserve to raise a separate codon, however, our present knowledge on their autoecology is too limited.…”

Since its publication, the article ‘Towards\ud a functional classification of the freshwater phytoplankton’ (Reynolds et al., J Plankton Res 24: 417–428, 2002), has attracted the attention of dozens of phytoplankton ecologists worldwide. These numerous applications of the functional classification to describe phytoplankton patterns in various aquatic ecosystems allowed the recognition of some uncertain features of this concept originating from various reasons. In this article, we attempt to facilitate the application of the functional classification, by providing a detailed description of the typical misplacements and by modifying some of the original habitat templates and species allocations. Furthermore, we discuss in this review those coda that were additionally described after the publication of the original article, and attempt giving an overview, as complete as possible, of the state of art

“…Diatoms, that need deep mixing depths to remain in suspension, typically grow in JanuaryApril. Long-lasting ice-cover favors the growth of the small sized Stephanocostis chantaicus (Scheffler & Padisá k, 2000). In years with short icecover, either Cyclotella tripartita (Scheffler & Padisá k, 1997) or C. pseudocomensis (Scheffler et al, 2003) dominate.…”

“…If so, dominance patterns must be rather closely related to the actual meteorological conditions as the annual manifestation of climate. A good example is Stephanocostis chantaicus in Lake Stechlin that develops relatively abundant populations only if the lake has a long-lasting, thick icecover (Scheffler & Padisák, 2000). During summer, phytoplankton development is more intensively driven by interspecific interactions that result in characteristic series, as hypothesized in Clements' (1916) ''superorganismic'' concept of succession.…”

The hypothesis that physical constraints may be as important, if not more important, than\ud biological ones in shaping the structure of phytoplankton assemblage was tested by analyzing longterm (11–29 years) phytoplankton series in eight lakes and nine sites located along a latitudinal gradient in the Northern hemisphere. Phytoplankton biomass was used and similarity of assemblages in same months of the annual data sets was then calculated by subtracting the Bray–Curtis dissimilarity index from 1. The extent of biological and physical forcing was partly based on ‘‘expert evaluation’’: the importance of four physical (light availability, temperature, conductivity, and sediment stirring up) and five biological variables (basic nutrients [SRP-, DIN-, SRSi-availability] as estimators\ud of competition straight, importance of grazing, and importance of parasitism) was evaluated month by month by arbitrarily scaling from 1 to 5 the intensity of each variable and then summing them in the appropriate subgroup. Since the number of\ud physical variables is less than that of the biological ones, the latter was rescaled to reach the same maximum attainable value of physical variables. The results showed an extremely high variability, making evident that each lake, although showing the same\ud metabolic processes, behaves as an individual with regard to its phytoplankton structure. More generally, it was possible to highlight a largely more important role of physical constraints in shaping both biomass and composition of phytoplankton. This is especially true in winter. In addition, the results were compared to the outcomes of the PEG model, since a plasticity\ud in the structure of phytoplankton much greater than that reported in this widely acknowledged model has been recorded in the data set used. This high variability found in this study in relation to physical constraints might also explain the different patterns of phytoplankton growth observed from Northern temperate to Mediterranean lakes as well as those occurring in shallow and deep lakes
