“…This agreed with Ali et al (2007) and El-Enany (2009). Also, this highest number of epiphytic rotifera was observed by Sakuma et al, (2002) and Arora and Mehra (2003). That because Rotifera preferred macrophytes which could be predominant body features, e.g.…”

The present work aims to study the relationship between some physico-chemical parameters and both planktonic and epiphytic microinvertebrates associated with the floating plant Eichhornia crassipes in River Nile at Qanater region. Water samples, planktonic and epiphytic microinvertebrates were collected seasonally from eight sites in the investigated region. The results indicated that the maximum occurrence of planktonic invertebrates (810 org./L) was recorded during Winter. Rotifera formed the highest percentage of zooplankton (96.77 %), followed by Copepoda (1.88 %) and Cladocera (1.10 %). Meroplankton and Protozoa formed the lowest dominant groups. Thirty seven planktonic species were recorded belonging to Rotifera (30 species), Cladocera (2 species), Copepoda (1 species), Protozoa (2 species) and Meroplankton (2 species). On the other hand, the maximum occurrence of epiphytic invertebrates (1612100 org./m 2 plant) was recorded during spring. Forty five species were recorded belonging to Rotifera (27 species), Protozoa (5 species), Cladocera (9 species), Copepoda (2 species) and Oligochaeta (2 species).The epiphytic microinvertebrates associated with the floating plant Eichhornia crassipes in River Nile at Qanater region recorded the highest number of species and groups than planktonic invertebrates. This indicates that the aquatic plant Eichhornia crassipes habitats are more diverse and have high species richness. The principal component analysis (PCA) was conducted between physico-chemical parameters and planktonic and microinvertebrates.

“…They recorded high number of genus Lecane. Sakuma et al (2002) stated that large number of Lecane remained on plant even after shaking 50 times macrophytes. This indicates that these animals were very strongly attached to submerged macrophytes.…”

“…Similarly, Cazzanelli et al [55] suggested that free-floating macrophytes are important as they create microhabitats for invertebrates in water bodies, where submerged macrophytes are scarce. Choi et al [56] and Sakuma et al [57] also reported that some cladoceran species migrate from plant to plant according to the seasonal growth of aquatic macrophytes. This led us to consider that the spatial distribution of B. chalybea flavovittata larvae could depend on habitat heterogeneity and structure created by aquatic macrophytes in wetlands.…”

In freshwater ecosystems, habitat heterogeneity supports high invertebrate density and diversity, and it contributes to the introduction and settlement of non-native species. In the present study, we identified the habitat preferences and trophic level of Brachydiplax chalybea flavovittata larvae, which were distributed in four of the 17 wetlands we examined in the Yeongsan River basin, South Korea. Larval density varied across four microhabitat types: open water area, and microhabitats dominated by Myriophyllum aquaticum, Paspalum distichum, and Zizania latifolia. Microhabitats dominated by M. aquaticum had the highest larval density, followed by those dominated by P. distichum. The larvae were more prevalent in silt sediments than in plant debris or sand. Stable isotope analysis showed that B. chalybea flavovittata is likely to consume, as a food source, other species of Odonata larvae. We conclude that successful settlement of B. chalybea flavovittata can be attributed to their habitat preferences. As temperature increases due to climate change, the likelihood of B. chalybea flavovittata spreading throughout South Korea increases. We, therefore, recommend continued monitoring of the spread and ecological impacts of B. chalybea flavovittata.

“…Indeed, the abundances of free-swimming chydorids in the studied habitats were shaped as follows: water milfoil > rigid hornwort > common reed > macroalgae > sublittoral > macrophytefree littoral. On the other hand, thick macrophytes may provide shelters for invertebrates that are potential pred- (Johnson and Crowley, 1980;Johnson et al, 1985), and may cause a midsummer decline in density, which is often observed in populations of chydorids (van de Bond et al, 1995;Sakuma and Hanazato, 2002;Sakuma et al, 2004). The densities of Chydoridae in Lake Piaseczno, when considered on average, changed according to the expected pattern, with large peaks in June and September and low levels, subsequently, during summer, especially for chydorids existing in beds of water milfoil and rigid hornwort.…”
