“…The trophi virgate, cardate, and uncinate represent the suctor feeders and are known as sessile rotifers because they depend on the food supply from organic matter and periphytic biofilm in the littoral area rather than direct food sources in the pelagic zone (Choi et al, 2013). Thus, the guild suctor is an indicator of benthic-pelagic coupling (Oh et al, 2017), and their predominance could be related to the hydrologic regime of the floodplain, because this guild presented high abundance during prolonged drought periods when the water bodies of shallow lakes were reduced, and the benthic-pelagic area was almost unified.…”

In floodplains, rotifers are among the most abundant zooplankton organisms and play an important role in ecosystem functioning. Here, we evaluated the distribution of six feeding guilds of rotifers including filter C1 (body size: <200 µm), filter C2 (body size: >200 to <600 µm), filter C3 (body size: >600 to <1000 µm), filter C4 (body size: >1000 µm), suctor, and predator for 11 years. We also analyzed the relationship between guild distribution and environmental parameters (i.e., chlorophyll‐a, phosphate, nitrate, ammonia, and inorganic suspended matter). Finally, we investigated the relationship between feeding guilds heterogeneity (abundance inconsistency) and environmental heterogeneity. Sampling occurred every 3 months from 2000 to 2010 in six shallow lakes of the Upper Paraná River floodplains. Filters C1, Filter C2, and suctors were the dominant feeding guilds. Nitrate and chlorophyll‐a shaped the temporal distribution of the guilds. An intermediate value of environmental heterogeneity was correlated with greater feeding guilds heterogeneity, potentially indicating that intermediate disturbance in the environmental variables may allow for greater differences in abundance distribution between rotifer guilds in shallow floodplain lakes. Our study elucidated the role of rotifers in food resource consumption, energy transfer, and competitive relationships in response to temporal environmental heterogeneity in subtropical floodplains.

“…Trophi 2 (virgate trophi) group had somewhat negative relationships with indices. Trophi 2 includes the genera Lecane and Monostyla , mainly known as attached rotifers (Choi et al 2013 ) depending their food supply on the biofilm and organic matters in the littoral area rather than direct food sources in the pelagic zone. It can be inferred that they are not directly affected by water qualities due to their characteristics of habitats and feeding habits.…”

Rotifer community is often used as a taxon-based bioindicator for water quality. However, studies of the planktonic community from the viewpoint of functional groups in freshwater ecosystems have been limited, particularly for rotifers. Because rotifers have various trophi types determining their feeding strategies, thereby representing an ecological niche, their functional feeding groups can act as biological and ecological indicators in lakes and reservoirs where planktonic communities are dominant. We analyzed the patterns of spatial distribution of the rotifer community in various reservoirs and then its relationship with water quality through redundancy and regression analyses. Compared with taxon-based composition, the response of trophi-based composition appears simplistic and showed clearer tendency in relation with water-quality variables. Each trophi responded differently by the degree of eutrophication indicating that each trophi group is possibly affected by environments such as the combinations of water-quality variables in different ways.

“…The high biodiversity of wetlands is partly caused by the stable environment created by low flow rates. However, owing to the complex habitat structures of wetlands, controlling various biological community interactions contributes greatly to maintaining biodiversity [ 5 ]. The complex habitat structures created by aquatic macrophytes and shrubs in wetlands significantly reduce negative interactions, such as competition and predation, and allow various competitors and predators to coexist in wetlands [ 6 ].…”

Hydrological characteristics of freshwater ecosystems are powerful determinants of the distribution of biological communities and changes in environmental factors. This study identified relationships between the wetland environment, rotifer community, and hydrological factors for 48 wetlands, to determine their impact on wetland conservation and management. Different hydrological factors produced different wetland environments, which influenced the rotifer community composition. The wetlands with “poor” “in/outflow function” and “shore stability” levels showed high conductivity, turbidity, depth, and concentrations of total nitrogen, total phosphorus, and chlorophyll a. In contrast, the dissolved oxygen levels and velocity were the highest in wetlands with “good” in/outflow function and shore stability variables. The nutritional status of each wetland affected the composition of the rotifer community. Some genera (Keratella, Brachionus, Anuraeopsis, Trichocerca, and Philodina) were found in wetlands with high concentrations of total nitrogen, total phosphorus, and chlorophyll a, and high turbidity and depth. In contrast, Ascomorpha and Ploesoma were found in wetlands with high dissolved oxygen levels and flow velocity. High densities of Lepadella, Lecane, and Testudinella were found in wetlands completely covered by macrophytes. The rotifer community distribution can be used to understand the trophic, current functional, and environmental status of wetlands.
