“…Only the four species in the ecotone of both lakes were recorded as the common species. Less number of common species might be due to two lakes situated in the different geographic and climatic region (Lemein et al, 2017). Jaccard's similarity index was found to be 3.44% which clearly showed that the communities under studies i.e.…”

“…The spatial distinction of communities demonstrated that the riparian vegetation zone constituted an internally differentiated ecotone (Klosowski, 1993). Both the lakes were found dominated by native plants (Lemein et al, 2017) but at Begnas lake an invasive species of Eichhornia crassipes is also present. As E. crassipes stands the worst aquatic weed throughout the tropics and subtropics, increasing of E. crassipes is a sign of the increase in cultural eutrophication and siltation.…”

“…So the communities were heterogeneous in nature (Palmik et al, 2013). The dissimilarity of the communities was due to different climatic condition, temperature, nutrient content, human approaches and etc (Lemein et al, 2017). The chemical and physical gradients influence the biota in many ways so species of ecotone of the lake does not depend on salinity alone but is the result of complex of factors (Reizopoulou et al, 2013).…”

Land-water interfaces of lakes are highly dynamic and are responsible for the stability and maintenance of ecosystems. This study was carried out to understand the ecotone vegetation and the physico-chemical characteristics of waters of Begnas and Rara lakes of Nepal. For vegetation survey, line transects (perpendicular bi-sector to lake boundary), were used along the lake boundaries at an interval of 500 m; three quadrats of 1 m x 1 m size were laid on each line transect (off shore, boundary line, and on shore). All vegetation species in the sample quadrates were recorded. For probing water quality, lakes were divided into three blocks, then sampling was conducted on a consecutive day. Physico-chemical parameters —temperature, pH, electric conductivity (EC), dissolved oxygen (DO), total dissolved solid (TDS), ammonia, and nitrate—were measured. A total of 55 species under 38 families and 28 orders were recorded from ecotone of Begnas lake. In Rara lake, 56 species of 41 families and 22 orders were recorded. Poaceae was the dominant largest family in Begnas which was followed by Asteraceae. In Rara lake, Rosaceae was the dominant family which was followed by Pinaceae. Temperature, pH, and DO values decreased with depth, but EC and TDS e increased with depth, in both Begnas and Rara lakes. Ammonia and Nitrate were below the detectable limit of the instrument, indicating low nutrient contents of both lakes. The study established the baseline information about the diversity of ecotone vegetation; both the lakes show clear changes in physiochemical parameters with lake depths.

“…Bulrush occur throughout the Great Lakes basin; thus, this trend likely reflects lower anthropogenic disturbance (water quality impairments among other potential disturbances) in the northern regions compared with southern regions. Bulrush zones may also be prevalent in higher quality northern sites because they are outside the area of Phragmites invasion at northern latitudes and because bulrushes tolerate the low nutrient concentrations that inhibit both Phragmites and Typha dominance (Albert and Minc 2004;Lemein et al 2017). This latitudinal trend may explain the lower overall variability in rank values within the bulrush zones compared to the high variability in the five vegetation zones with the lowest average rank values: Lily, PSP, Phragmites, SAV, and Typha.…”

Coastal wetlands of the Laurentian Great Lakes are vital habitats for biota of ecological and economic importance. These habitats are susceptible to water quality impairments driven by runoff from the landscape due to their location along the shoreline. Monitoring of the overall status of biotic and abiotic conditions of coastal wetlands within the Great Lakes has been ongoing for over a decade. Here, we utilize measurements of aquatic physicochemical and land cover variables from 877 vegetation zones in 511 coastal wetland sites spanning the US and Canadian shorelines of the entire Great Lakes basin. Our objective is to develop water quality indices based on physicochemical measures (Chem-Rank), land use/land cover (LULC-Rank), and their combined effects (Sum-Rank and Simplified Sum-Rank), for both vegetation zones and wetland sites. We found that water quality differed among wetland vegetation types and among Great Lakes regions, corroborating previous findings that human land use alters coastal wetland water quality. Future monitoring can use these straightforward, easy-to-calculate indices to assess the abiotic condition of aquatic habitats. Our data support the need for management efforts focused on reducing nutrient and pollution loads that stem from human activities, particularly in the developed southern portions of the Great Lakes basin.

“…Many factors would restrain vegetation restoration of degraded wetlands, including water supplement (Guo et al, 2017), nutrient availability (Mitchell et al, 2015), cultivation period (Barrett and Watmough, 2015), seed banks (Liu et al, 2005;Bai et al, 2014), restoration time and so on (Lemein et al, 2017). Usually, vegetation would be more and more similar with target wetlands as restoration time increasing.…”

Deyeuxia angustifolia wetlands were widely distributed in the Sanjiang Plain in Northeast China. Due to strong demand for food production, large-area wetlands were reclaimed to farmlands, which threatened regional ecological security greatly. Since the 21th century, returning farmlands to wetlands was widely adopted for natural restoration in the Sangjiang Plain. As the first reflection of wetland restoration, vegetation succession of restored D. angustifolia wetlands should be fully assessed. In this study, vegetation investigation was carried out in three restored D. angustifolia wetlands with 5, 8 and 12 yr restoration, respectively. Meanwhile, a natural D. angustifolia wetland was selected as reference wetland. Results showed that community composition changed greatly and there was visible community succession. Community dominant species changed from composite to gramineae as restoration time increasing. At first, weeds community appeared in the restored wetlands, especially the xerophytes developed to the pioneer species rapidly. And then, mesophytes and wetland species became the dominant species in the restored wetlands. Finally, wetland species, especially D. angustifolia, occupied the dominant position of restored community. Shannon-wiener index (H) and Simpson index (D) both decreased to close to natural D. angustifolia wetlands. Compared with natural D. angustifolia wetland, species composition and diversity in restored wetlands were more complex and higher. As restoration time increasing, there were not significant differences between community characteristics of restored wetlands and natural wetland. All these suggested that vegetation in reclaimed D. angustifolia wetland could be restored naturally, but its restored period is 10 yr at least. From another angle, it is important to protect current natural wetlands.
