“…both species were occurring during winter and pre-monsoon seasons only (Table 5). Hrivnak et al (2006), Veit and Kohler (2003), Mahapatra et al (2011) also found similar trends of results in their respective studies. The summary of overall observation of identification of tolerant and sensitive aquatic macrophytes grown in the respective selected study areas are shown in Table 6.…”

Abstract. Macrophytic vegetation plays an important role in maintaining the ecosystem of a lake. Aquatic macrophytes are key components of waterscape because they provide food, affect nutrient cycles and mainly because they increase the habitat complexity, which enhance biodiversity in littoral region. The present region of Bundelkhand lies between approximately 23º10' and 26º27' North latitude and 78º4' and 81º34' East longitudes. There are five aquatic bodies have been selected for study because all of the study areas are situated in the middle of the city and due to anthropogenic activities they were heavily polluted. Aquatic macrophytes were observed quarterly in three years from five different study areas. There are total twelve species of aquatic macrophytes have been found in selected study areas. Eichhornia crassipes and Hydrilla verticillata were found abundantly almost every season throughout the year in almost every study areas.

“…In the last decade, mapping of macrophytes and studies of interaction between macrophytes and environment in running waters were very intensive in Danube countries e. g. Germany (Veit & Kohler, 2003), Austria (Janauer & Wychera, 2000), Hungary (Pall et al, 1996), Serbia and Montenegro (Vukov et al, 2003) and Romania (Sarbu, 2003). In the territory of Slovakia, only few data have been published (Hrivnák et al, 2003(Hrivnák et al, , 2004Oťaheľová & Valachovič, 2003.…”

Diversity of aquatic macrophytes in relation to environmental factors in the Slatina river (Slovakia)

2006

Distribution and plant mass of aquatic macrophytes, and their relation to environmental conditions was studied in the submontane-colline Slatina river in 2004. Diversity of macrophytes was low, only 8 vascular plants, 3 mosses and group Algae filamentosae were found. Myriophyllum spicatum is dominant species, Fontinalis antipyretica, Rhynchostegium riparioides and Algae filamentosae are frequent. Interactions between flow class, bed material, depth of water and the first three mentioned macrophytes, as well as Jungermannia leiantha were detected. Sparganium erectum prefers more antrophogenic conditions and Myriophyllum spicatum prefers the light. According to cluster analysis, three distinct and ecologically well separated parts of the river were identified. Based on Reference index, poor ecological status for the studied part of the Slatina river was estimated.

“…In particular, the rivers flowing through agricultural landscapes are often exposed to high influxes of nutrients, as well as morphological alterations, both of which negatively influence the biodiversity of riverine ecosystems [ 23 ]. Beside the valuable role of macrophytes as the indicators of the current human pressure, aquatic macrophytes have been used by many researchers to monitor the long-term changes in rivers [ 24 , 25 , 26 , 27 , 28 , 29 ], as well as in lakes [ 30 , 31 , 32 ].…”

The aim of this study was to reveal the changes of macrophyte community over time and along the course of the Ižica River. In 1996, 2000, and 2016, we surveyed the distribution and abundance of macrophyte species in the lowland Ižica River, which originates in the town of Ig and then flows through an agricultural landscape. We calculated the River Macrophyte Index (RMI), which reflects the ecological status of the river. In 2016, ecomorphological conditions of the river, using the Riparian, Channel and Environmental inventory, were also assessed. In just 10.5 km of the river, we identified 27 taxa of macrophytes, among which Potamogeton natans, Sagittaria sagittifolia, and P. perfoliatus were the most abundant. Detrended correspondence analysis showed that, in 1996, the surveyed stretches differed more according to macrophyte composition than in the following years. The assessed environmental parameters explained 43% of the variability of the macrophyte species; riverbank stability explained 20%, riverbed structure 10%, while vegetation type of the riparian zone and bottom type explained 7 and 5%, respectively. The species composition of the macrophyte community revealed significant changes over the years of the riverine ecosystem. Comparison of RMIs in 1996 revealed better conditions in the upper and middle part of the river, while in 2016, the situation was the opposite, since the conditions in the upper part deteriorated significantly over time, while the lower part of the river had the best ecological status. These changes may be due to a considerable increase in the population of the settlement Ig, while better status in the lower course of the river may be a consequence of improvements in the infrastructure and the use of sustainable agricultural practices in the catchment due to the establishment of a formal area of protection.
