The selected theme of the workshop was “Trait-Based Approaches in Micro-Algal Ecology”. The discussions presented during the workshop sessions resulted in the 18 articles contained in this Special Issue. There are 6 main thematic aspects developed by the participants: 1. Shape and size: are these traits easy to measure? 2. Spatial scales: when and where to look for microalgae? 3. Climate and extremes of ecological gradients: hot topics of this century. 4. Metaphyton and metaphytic habitats: life beyond plankton and benthos. 5. Microalgae in water management: phycology in practice. 6. Traditional and new methods: perspectives and comments. Trait-based approaches in microalgae ecology, although requiring further investigation and methodological development, represent a valid tool for refining the analysis of environmental variability in aquatic ecosystems. The papers presented in this Special Issue demonstrate that these approaches are extremely useful not only in the study of planktic algae but constitute a thoughtful method for the analysis of benthic and metaphytic microalgae in a wide variety of aquatic ecosystems.

Their representatives can be found in terrestrial, aquatic, polar, desert regions and have been investigated so far from various aspects. However, the available information about Klebsormidium isolates from lamp-flora is very limited. In our work, we examined a Klebsormidium strain isolated from a Hungarian cave. The temperature optimum of its photosynthetic performance was tested by oxygen yield measurements and pulse-amplitude-modulated fluorescence, which were completed by determination of specific growth rates at different temperatures, from 10 to 40 °C. In addition, we also evaluated the brassinosteroid (BR) content of these cultures. Our results indicated that the studied microalga is capable of growing from 10 to 40 °C, with a 20–25 °C temperature optimum; these findings were in accordance with the observed hormone levels. Regarding photosynthetic performance, the oxygen yield and chlorophyll fluorescence measurements showed maxima at 30–40 °C and 35–40 °C, respectively. Moreover, the examined Klebsormidium strain demonstrates traits associated with cave adaptation, i.e., by high light utilisation factor (α) and diminished light adaptation parameter (I k ) values.

Their phytoplankton community is often dominated by the cyanobacterium Limnospira fusiformis , the main food of lesser flamingos. In the early 2010s, the population of the cyanobacterium collapsed and the picoplanktic green alga Picocystis salinarum became dominant in Lake Nakuru. Consequently, lesser flamingos had to migrate to other lakes in search of food. To establish the reasons for the success of P. salinarum , photosynthesis measurements have been performed on monoalgal cultures of both species. The examined environmental variables (temperature, light intensity) were not responsible for the dominance of P. salinarum either alone or in their any combination. Moreover, photosynthetic activity of the cyanobacterium was higher by an order of magnitude during all light and temperature treatments. Co-cultivation of L. fusiformis and P. salinarum in a chemostat revealed that a possible reason for the Limnospira replacement can be a rapid and remarkable increase of conductivity, as P. salinarum showed higher level of tolerance to this rapid change. Shortly after returning to the initial conductivity levels, the population of L. fusiformis recovered quickly.

Such knowledge is implicitly based on the analysis of the realized niche of the different populations, i.e. of the sets of conditions within which populations show a positive growth. The range of phytoplankton morphological traits variability is evolutionarily selected to maximize the ecological performance of species while they are entrained in the spectrum of turbulent flows. In addition, most phytoplankton species exhibit high morphological plasticity that can further optimize their performance under reduced environmental variability. Although this plasticity is well known, it is seldom considered in phytoplankton studies. Morphological analysis could therefore be used as a tool to estimate the environmental variability within which a species can persist and, ultimately, the niche width of phytoplankton populations. This opinion paper tries to answer the questions: to what extent can the morphological variability of phytoplankton offer a synthesis of the environmental variability of aquatic ecosystems?. Do the morphological traits contain sufficient information to describe the width of the realized niche of phytoplankton species? What can we do to fill eventual gaps in our knowledge?

Their protection is of crucial importance since they support an unusually high biodiversity relative to their size. The present study aimed at selecting the main drivers, especially the role of the morphological variables, shaping benthic diatom communities in unique, but rarely investigated forest pond ecosystems in the temperate region, using traditional (species-based methods and diversity indices) and novel approaches (trait-based methods and functional diversity indices) of diatom ecology. Therefore, we analyzed the effects of the environmental (temperature, conductivity, colour, shading, pH, nutrient forms, anions) and morphological (surface area, depth) variables of 70 temperate, forest ponds located in two regions of Hungary on the composition (species- and trait-based) and diversity (traditional and functional) of their benthic diatom communities. Based on the multivariate analyses, no regional differences in the environmental and morphological variables were been observed among the ponds. Our results showed that both environmental variables and lake morphology had significant effects on the benthic diatom communities, but they contributed to their variation with different proportions. Environmental variables such as nutrient content (rsoluble reactive phosphate = 0.72) and conductivity (r = 0.65) affected mostly the species composition, and the traditional diversity metrics (rtotal phoshate = −0.42, rconductivity = −0.54). In contrast, morphological features of the ponds were the most important drivers of diatom trait composition. This functional response of diatoms manifested in the selection of species according to their size, shape and lifeforms, moreover, in changing of functional diversity. Overall, this study revealed the complex interplay between environmental variables and lake morphology in shaping the composition of benthic diatom communities. Furthermore, it highlights the necessity to apply different methods to understand the ecology and functioning of these special aquatic ecosystems.
