“…We also found high relative proportions of euglenoids; it is recognized that the drying phase of temporary water bodies is characterized by a very diverse assemblage mainly formed by euglenoids (W1 and W2 FG) often accompanied by dinoflagellates (L o FG) because they generally persist to the point of complete desiccation of the pond (Naselli-Flores and Barone, 2012). The dominance of benthic Bacillariophyceae (C and T B FG) during the initial period was favored by the absence of macrophytes as it is recognized that heavy diatoms rely on turbulence to counteract sedimentation (Padisák et al, 2003;Allende et al, 2009;Stević et al, 2013).…”

“…Wetlands are amongst the most sensitive ecosystems and may become fragmented during drought periods (Angeler et al, 2010). Recently the number of studies exploring the effects of drought on wetland communities is increasing (Bucak et al, 2012;Granado and Henry, 2014;Rojo et al, 2012;Stević et al, 2013). However, studies are still limited compared to those regarding floods and other disturbances (Lake, 2011).…”

“…Thus, the probability of the prevalence of certain functional groups, rather than species dominance, can be better narrowed down for a given set of environmental conditions. The functional group approach helps to understand why differing phytoplankton species are selected over others in an assembling community, as well as why its composition varies at both a temporal and spatial scale (Reynolds et al, 2002;Naselli-Flores and Barone, 2012;Stević et al, 2013).…”

“…According to Williams (2002), these lakes are considered freshwater lakes, an in our study, they were associated with a predominance in abundance of Chlorophyceae and Euglenophyceae (see Fig. 3(b)), two groups which are frequently found in freshwater lakes in lowland areas during the warm season (Garcı´a de Emiliani, 1997; Stevict et al, 2013).…”

-This study aimed to determine the factors affecting plankton structure along a salinity gradient during the summer in high-altitude endorheic lakes in Catamarca Province (Argentina). During the summer 2013, eight lakes located between 3000 and 4300 meters above sea level were sampled in a 6-day period being analysed plankton, limnological variables and flamingo abundance. Principal Component Analysis explained 80% of the system variability, permitting lakes to be ordered by salinity: subhaline (SH), hypohaline (HH) and mesohaline (MH). A total of 101 phytoplankton taxa were registered, having Bacillariophyceae the highest richness (43 species registered). HH lakes were dominated by Bacillariophyceae (between 65 and 100%), while Chlorophyceae and Euglenophyceae were more abundant in SH and MH lakes. Zooplankton was poorly represented in richness (only 21 species were registered). MH lakes were dominated by Copepoda ( > 85% of total abundance) and HH lakes by Rotifera ( > 51% of total abundance). It was not found a clear pattern in SH lakes. The redundancy analysis explained 70.7% of phytoplankton variability and 75.7% of zooplankton variability. Bacillariophyceae presence was associated with availability of dissolved silica (Si), while Euglenophyceae and Chlorophyceae were associated with a higher nitrogen:phosphorus ratio. Cladocera and Copepoda abundance were linked to Euglenophyceae abundance and the area of lakes while Rotifera displayed a positive relation with the concentration of dissolved organic matter. We conclude that both phytoplankton and zooplankton abundance are mainly controlled by Bottom-Up forces including dissolved Si for Bacillariophyceae, and availability of Euglenophyceae for zooplankton while salinity and altitude have an effect on plankton richness distribution.

“…Functional group S1 is usually characterized by cyanobacteria, are adapted to high temperature, forming groups, floating, and multiplying fast, which dominate during the summer period (Çelekli and Öztürk, 2014). Some studies have shown that populations of Cyanobacteria, which comprise a few species within the functional group of S1, regularly occur in summer in different water bodies around the world (Rücker et al, 1997;Padisák et al, 2003;Gemelgo et al, 2009;Borics et al, 2012;Li et al, 2013;Stević et al, 2013;Hu et al, 2016). Both Lo and Y have a flagellum that allows their survival in multiple water layers when adverse conditions such as weather changes and water body disturbance are encountered (Padisák et al, 2009;Naselli-Flores and Barone, 2003).…”

The functional groups approach is an efficient way to analyze seasonal changes in phytoplankton biomass as it is based on the physiological, morphological, and ecological attributes of the species. In this study, we identified the functional groups and driving factors behind short-term succession in phytoplankton communities. We analyzed physical, chemical, and biological factors of the Maixi River in Baihua Reservoir (BHR) from August to September, 2013 (summer, phase I) and March to May, 2014 (late spring and early summer, phase II). The 226 samples collected were divided into 23 functional groups. In phase I, phytoplankton biomass ranged from 4.88 to 30.59 mg·L -1, and the group S1 (Pseudanabaena limnetica) had the greatest biomass. In phase II, phytoplankton biomass ranged from 2.22 to 50.61 mg·L -1 , and groups Y (Cryptomonas sp.) and S1 (P. limnetica) had the greatest biomass. Dominant functional groups in the Maixi River changed from S1 + D + Y + Lo in phase I to Y + S1 in summer. Changes in the phytoplankton community varied between 0 and 0.144 day -1 in phase I and between 0.008 and 0.389 day -1 in later spring and early summer. This showed a steady-state phytoplankton community during the two phases, in which the functional groups S1 (P. limnetica) and Y (Cryptomonas sp.) were dominant. Pseudanabaena limnetica, Synedra sp., Peridinium sp., and Cryptomonas sp. were dominant during summer, contributing to 70% of the total biomass in the steady-state community, and P. limnetica, Synedra sp., Cryptomonas sp., and Chlamydomonas sp. were dominant during later spring and early summer, contributing to 60% of the total biomass in the community. Groups S1, D, and Y formed easily in the Maixi River, but P. limnetica was the dominant species in the eutrophic conditions of the Maixi River. According to biotic and abiotic factors, we concluded that the Maixi River is hypertrophic, and water resource management should take blooms of P. limnetica occurring in May into account. Temperature and dissolved oxygen were the critical factors affecting the steady-state of the phytoplankton community in late spring and early summer and summer, respectively. Because the Maixi River is an important source in the BHR, its phytoplankton functional groups directly affect the ecological balance of the water environment.
