“…Through this investigation, it was possible to deduce the relationships between species' ecological characteristics and their growing environment. There is a lack of research on this problem in wetlands, even though it is generally accepted that ecological development conditions affect species richness through decreased nutrient availability and slower rates of nitrogen mineralization and nitrification (Rajilesh et al, 2016;Cruz et al, 2020). The relevance of water composition and lighting conditions for their maintenance was highlighted by the current study, which showed a correlation between practically all ecogroups of macrophytes and the ecological parameters of locales.…”

Studying structural and functional biodiversity in relation to various environmental factors is currently extremely relevant because aquatic ecosystems are a significant source of biological diversity and make up a significant part of the biological productivity of the Earth, they perform many functions, and they are valuable and important for the stability of biotic communities. With this in mind, the task to determine the floristic composition of the Teteriv ecological corridor as a prototypical river landscape in the northern part of Ukraine, to analyse the structural and functional features of the species diversity of macrophytes therein, and to dissect this diversity into its component parts according to its place of origin, its life form, and its relationship to environmental factors was set. The number of species and their predicted coverage in areas with different anthropogenic pressures within the Teteriv ecological corridor were analysed within ecological zones based on the study's findings. It was demonstrated that the integrated ecological indicator of water quality was crucial to the growth of phytocenoses in high-anthropogenic-load regions. The communities may survive in environments where dissolved oxygen is low, muddy sediments are abundant, and anaerobic processes predominate in the transformation of substances. Additionally, they can propagate in floodplains, wet swampy ecotopes, and other environments where water is present for extended periods of time. Most of these communities are not picky about their habitat, as they may thrive in a variety of situations, including slightly acidic or neutral substrates, varying amounts of nitrogen and minerals in the soil, and mild salinization of the plant life. An increase in the number of representatives of individual ecogroups can attest to changes in the ecological state of aquatic ecosystems and have practical significance in detecting increased anthropogenic pressure on aquatic ecosystems

Wetlands are vital and dynamic components of the global ecosystem, providing a wide range of ecosystem services such as water control and biodiversity. During 2015–2019, plant diversity and distribution of wetlands were studied in forty areas of the Mardan division, Khyber Pakhtunkhwa, Pakistan. A total of 282 vascular wetland plant species were identified, divided into 192 genera and 73 families. Poaceae, with 41 species, is the most diverse family of wetland plants, followed by Asteraceae, with 26 species. In the present study, wetland plants are classified based on the Cook classification system. It is interesting to note that all the life forms were present in the study area except Plankton. Helophyte life form was represented by the highest number of plants with 177 plants and 62.5 percent of total wetland plants, followed by Tenagophyte with 42 plant species (14.8%) and Hyperhydate with 27 plant species (9.5%). Based on the distribution pattern of 282 species in 40 wetland sites, the most common plant species found was Euphorbia helioscopia, recorded from 36 locations, followed by Cynodon dactylon which was found in 32 locations. In Mardan division, the Gulshan Abad Khuwar had the highest number of species occurrences (83 species) accounting for 32% of all species, followed by Alo Khwar (59 species, 23%) and Hathian Khwar (50 species, 19%). The current work presents a comprehensive and field-based detailed survey of wetland plant distribution in this region, filling knowledge gaps in the Himalayas in particular, and having broader implications for wetland management policy and practice. Unfortunately, wetlands of the research area are facing high pressure due to an increase in human population, overgrazing, deforestation, construction of buildings and roads. The filling up of these water bodies is resulting in the loss of hydrophytic species diversity. Therefore, these wetlands need proper attention and effective protection from anthropogenic disturbances.
