“…Conversely, Alternanthera philoxeroides (Mart.) Griseb., which is known as one of the world's worst tropical aquatic weeds (Wang, Wang, Bowler, & Xiong, ), showed relatively lower AED (2.3) and higher ED (127.5) values. Thus, the AED is useful to identify individuals that make a lower contribution to the overall evolutionary history and serves as a basis to evaluate species conservation.…”

Water pollution is one of the most serious aquatic environmental problems worldwide. In China, recent agricultural and industrial development has resulted in rapid changes in aquatic ecosystems. Here, we reveal the effects of water pollution on the phylogenetic community structure of aquatic macrophytes in the Tiaoxi River, China. We placed a rectangular plot at 47 sites within the Tiaoxi River from the mouth of the river to 88.5 km upstream, in which we recorded species abundance and measured 22 physico‐chemical variables. Bayesian phylogeny using the rbcL and matK gene sequences was employed to quantify phylogenetic α‐ and β‐diversity, and test the phylogenetic signal in four growth forms: emergent, floating‐leaved, free‐floating, and submerged. Within communities, water contamination and phytoplankton abundance decreased species richness and phylogenetic diversity, which resulted in phylogenetic clustering; species within communities were more closely related to each other than expected. Between communities, differences in geographical distance and phytoplankton abundance resulted in phylogenetic dissimilarity among plots. Aquatic macrophytes showed phylogenetic signals in which related species responded more similarly to disturbance. Thus, the observed patterns could be explained by environmental filtering and suggested that water pollution by human activity has added more filters to the existing environmental filters that drive the species assembly of macrophyte communities.

“…Plant invasion has a negative impact on biodiversity and ecosystem function, resulting in large-scale social and economic effects (Willby 2007, Hershner & Havens 2008, H. Wang et al 2016. Rapid global change has the potential to enhance such impacts at a large scale (Vitousek et al 1996, Bradley et al 2010.…”

Invasive aquatic plants have the potential to threaten ecosystem stability and biodiversity in non-native ranges; it is therefore necessary to prevent and control such invasions. While environmental heterogeneity might drive functional trait variation in plant species across different spatial scales, the drivers of trait variation over a large spatial scale are not well understood for aquatic invasive plants. Understanding functional trait variation across space and potential environmental drivers might improve our understanding of habitable conditions for predicting where an invasive plant species might be found. Here, we studied Hydrocotyle vulgaris (Araliaceae) in Zhejiang Province, China, and propose that environmental spatial heterogeneity might drive functional trait variation of this invasive aquatic plant over a large scale. The investigation was conducted across 99 plots at 7 sites with H. vulgaris. We found significant variation in functional traits over a large scale, and these functional traits were significantly different across a variety of environmental conditions. Specifically, there were significant relationships between environmental factors (i.e. temperature, precipitation, solar radiation, and water vapor pressure) and functional traits, including specific leaf area, interval length, and specific interval length, indicating that spatial environmental heterogeneity might drive the variation in functional traits (especially leaf and clonal traits) of H. vulgaris, over a large spatial scale. Our study thus provides new insights into understanding the invasiveness of H. vulgaris.

“…Many species of aquatic plant are invasive species (Oyedeji and Abowei 2012). These plants cause local losses of species diversity and alter ecosystem structure, resulting in a significant negative impact on aquatic biodiversity and water quality (Brundu 2015;Chamier et al 2012;Wang et al 2016;Zedler and Kercher 2004). In India, over 140 aquatic plants are reported to have attained the status of aquatic weeds in different situations (Gupta 2012;Naskar 1990;Shah and Reshi 2012;Varshney et al 2008).…”

Panda M, Samal RN, Bhatta KS, Lenka S, Rout J, Patra HK, Nanda S. 2018. Diversity and distribution of vascular macrophytes in Ansupa Lake, Odisha, India. Bonorowo Wetlands 1: 1-12. Macrophytes are indispensable component of any wetlands. They are the base of the trophic structure and variously affect function of aquatic ecosystem. Large invasion of macrophytes enforced for present studies in Ansupa Lake, the largest freshwater lake of the state Odisha (India) to identify the causative plant species. Regular field inspection, quadratic sampling and specimen collections were carried to identify the present macrophytes of the lake and their quantitative aspects like frequency of occurrences, abundance, values of diversity indices, adaptation and growth forms and species distribution etc. A total of 244 macrophyte species were identified that includes 182 semi-aquatic and 62 obligatory aquatic macrophytes. The latter group had 35% submerged, 15% free floating, 31% rooted floating and 19% marshy plant species. The comparison of growth form showed 64% annuals and remaining 36% perennial plants. The diversity indices resulted, Simpson complement index-0.561, Shannon-Weiner index-1.367, Species richness index 3.079 and Species evenness index-0.156. The study showed that the lake provides suitable habitats for existence of a diverse group of macrophytes but still due to large invasion of few species has threatened the lake which needs to be managed properly to restore the health of this natural resource for the benefit of mankind.
