“…This can be linked with the observation of that, particularly on nutrient-rich sediments, the growth rate of E. nuttallii plants is significantly higher than that of M. spicatum. For M. spicatum is found that it is a species with a wider range of substrate type (Willby et al 2000;Clarke & Wharton 2001;Hrivnák et al 2009). HoweverM.…”

Invasive alien species Elodea nuttallii was introduced into the Drava River (Slovenia) in 2007. The spatial distribution of native macrophyte species Myriophyllum spicatum and the invasive alien species E. nuttallii was studied in two impoundments, HPP Vuhred and HPP Mariborski otok in the years 2009, 2010 and 2011. The very heterogeneous environment of the Drava River had resulted in dynamic and non-uniform distributions of E. nuttalli and M. spicatum in both impoundments. The distribution of E. nuttalli was shown to be suppressed in river stretches exposed to great turbulence. It had, however, successfully invaded areas with gentle slope of littoral, low exposition to main water flow and muddy sediment and prevailed against the native species M. spicatum. The latter was more abundant than E. nuttallii in stretches exposed to higher flow velocity. Thus, the competitive success of M. spicatum and E. nuttallii depended on environmental conditions. Our results lead to the prediction that E. nuttallii will increase further in the river Drava, causing serious economic problems.

“…The results of the ecological assessments of the waterway that use macrophytes as indicators cannot be generalized, as they are specific to geographical locations where the study has been conducted, as well as the waterway hydromorphology and the method of study [5,58,[67][68][69][70][71]. That is why it is essential to standardize and streamline the study procedures in order to produce national macrophyte map and understand the complex interactions between macrophytes and the environment [72].…”

Trapa natans is one of the very few plants that generate so many contrasting views: it is highly endangered in Europe, invasive in North America and Australia, yet highly valued in India and China due to its nutritional and medical properties. Its endangered status in most of the Europe has prompted significant conservation efforts aimed at retention and expansion of its population. T. natans is currently on the red list of many European countries and is included under “Appendix I” of the “Convention on the conservation of European wildlife and natural habitats” (Bern Convention) and IPA list (IPA criterion A, threatened species). The unusual circumstances, i.e. endangered status of T. natans in the region on one hand and its expansion in Serbia on the other, are the reason behind this research that aims to present the distribution, floristic composition and ecological conditions of ass. Trapetum natantis stands in hydromeliorative facilities (Serbia), comprised of 28 hydrophytes. In the analyzed stands, based on the long-term phytocenological studies, we have singled out four floristic and ecological groups: the stands in which T. natans predominates, the stands with Ceratophyllum demersum, the stands with lemnids plants (Lemna minor, L. gibba, Spirodela polyrrhiza) and Salvinia natans and the stands with Hydrocharis morsus-ranae. In the researched localities, the differentiation of ass. Trapetum natantis stands is predetermined by the phosphorus and nitrate content, as well as pH and BOD₅ levels.

“…A number of studies have found these to be the most significant factors governing the abundance, composition and distribution of macrophytes (Bini et al 1999;Lougheed et al 2001;Pandit 2002). It is well documented that the underwater light plays an important role in determining the depth distribution of different groups of aquatic macrophytes (Sculthorpe 1971;Chambers and Kalff 1985;Dale 1986;Chambers and Prepas 1988;Hrivnak et al 2006). Water level is closely related to light transmission, with deeper water hindering the processes of scattering and absorption (Wetzel 1988;Sand-Jensen and Borum 1991).…”

Aquatic macrophytes constitute important components of many freshwater ecosystems. The manifold role of aquatic macrophytes in freshwater habitats is closely linked to their distribution, which in turn depends on a myriad of factors. Foremost, among these are light, water temperature, water quality changes and nutrient enrichment, sediment composition and fluctuations in water levels. Light and temperature are of paramount importance in determining the distribution (with depth, season and latitude), thereby influencing productivity and species composition as well. Sediment compositions markedly affect the growth rates of macrophytes which in turn have a profound influence on the distribution of aquatic macrophytes. Water quality changes and nutrient enrichment can cause considerable variations in the species richness, composition, and density of aquatic vegetation. The reduction in water levels could bring drastic changes in the species composition and distribution of macrophytes. Factors associated with competition, herbivory, land use and land cover changes etc. also play an important role in shaping macrophyte distribution and community structure. In this review we examine both biotic and abiotic factors that influence the structural attributes like species composition, distribution, abundance and diversity of aquatic macrophytes.
