“…Large stands are also found in the USA, Canada, New Zealand, Europe, and Japan [23]. It usually growths in lakes, ponds and slow-moving waters at a depth of 0.1 to 8 m, usually between 0.1 and 1.5 m [24], and less frequently in shallower and flowing water [25]. In addition, it effectively uses higher levels of light in clean water [26].…”

There are insufficient data for the development of process design criteria for constructed wetlands systems based on submerged plants as a major treatment agent. The aim of the study was to evaluate the oxygen transfer capacity (OTC) of E. densa, in relation to wet plants’ mass (w.m.), and the influence of E. densa on the oxygen concentration and contaminants’ removal efficiency from municipal wastewater. The obtained oxygen concentration and temperature data allowed to calculate the OTC values (mg O2·L−1·h−1), which had been related to wet plants’ mass unit (mg O2·L−1·h−1·g w.m.−1). The efficiency of wastewater treatment was determined in relation to initial wastewater content in the mixture of wastewater and tap water (0%, 25%, 50%, and 100%) during 3 days of the experiment duration. The simulation of day and night conditions was done by artificial lighting. Before and after finishing the second experiment, the COD, Ntotal, and P-PO4 concentration were analyzed in wastewater solutions. The OTC ranged from 3.19 to 8.34 (mgO2·L−1·h−1·g w.m.−1), and the increase of OTC value was related to the increase of wet plant’s mass. The research showed that E. densa affected positively on the wastewater treatment efficiency, and the highest efficiency was achieved in 25% wastewater solution: 43.6% for COD, 52.9% for Ntotal, 14.9% for P-PO4.

“…According to Rimac et al (2018) The Lake Edku is one of the northern coastal lakes in Egypt, located at the western part of the Nile Delta east of Alexandria and west of Rosetta (Rashid), Situated at 30 km NE of Alexandria. It is one of four coastal deltaic lakes that are connected to the Mediterranean Sea; between altitudes 30֠ 8 ' to 30֠ 28 ' E & latitudes 31֠ 10 ' to 31֠ 8 ' N. It has an area of 126 km 2 and water depth ranging from 50-150 cm.…”

“…It is native to the coast of southeastern Brazil, Argentina, and Uruguay (Yarrow et al, 2009). The plant is considered naturalized in the Eastern United States (Cook & Urmi-König 1984), North America (Les & Mehrhoff 1999), Asia ( (Haramoto & Ikusimsa 1988, Alfasane et al 2010, Australia (Roberts et al 1999), Africa (Maire 1952;Simpson 1989;Coetzee et al 2011) and Europe (Medina & Cirujano 1995;Sergin 2008;Kikodze et al 2010;Hussner 2012;Medvecká et al 2012;Millane & Caffrey 2014;Wasowicz et al, 2014;Fominykh et al, 2016 andRimac et al, 2018). According to Yarrow et al (2009), E. densa has been successful as an introduced species and a highly efficient invader due to its high biomass production, fast vegetative reproduction and efficient dispersal, and he considered it as an ecosystem engineer that is capable of modifying or regulating important ecosystem process by preventing the resuspension of sediments and controlling the growth of phytoplankton.…”

First record of Egeria densa Planch. (Hydrocharitaceae) for the aquatic Flora of Egypt

Egeria densa Planch. is reported for the first time for the aquatic flora of Egypt. This species is a South American aquatic plant species considered highly invasive outside of its original range. In Egypt, the species may have been introduced as an aquarium plant and has long been wrongly identified as Elodea canadensis. However, it was collected from wild habitat at the northern lake of Egypt (Idku Lake). The article presents data on the comprehensive morphological and palynological features, distribution, ecological notes, and conservation status in Egypt of the newly recorded taxon, as well as photographs of herbarium samples, were also provided. This species has not been reported in North Africa, except for Algeria. The new record of its presence in Egypt fills the gap in its general distribution in the warm temperate region of the world. Based on the present study Hydrocharitaceae in Egypt, is now represented by 7 genera viz. Halophila, Thalassia, Ottelia, Vallisneria, Elodea, Najas and Egeria. The present data indicate that there are insufficient collections of Egeria densa in Egypt considering that the aquatic flora of Egypt is poorly known.

“…Although many new species have been discovered and the distribution and ecological patterns have been clarified within this project, the majority of these data have not yet been published. While discoveries of macro-algae (Alegro et al, 2016;Koletić et al, 2017Koletić et al, , 2018Koletić et al, , 2019Koletić et al, , 2020, aquatic bryophytes (Alegro et al, 2019;Rimac et al, 2019;Šegota et al, 2019a) and invasive aquatic plants (Rimac et al, 2018) have been readily published, data on general aquatic vascular flora (Šegota et al, 2019b) are still largely unprinted.…”

As many as 963 herbarium sheets featuring 76 aquatic plant taxa from the ZA collection were digitised and published online through the Virtual Herbarium. Aquatic plants have been collected over a period of 176 years, with three peaks (second decade of the 20th century, in the 1940s and 1950s, and in the current decade). Most of the specimens were collected in Croatia and a smaller number in neighbouring and geographically close countries. The importance of the collection is expressed through the specimens of many rare and threatened species, because it represents the only evidence of their presence in Croatia (the regionally extinct Caldessia parnassifolia, as well as Luronium natans, Callitriche platycarpa, C. truncata, C. hermaphroditica, Potamogeton alpinus, P. compressus, P. polygonifolius, Nuphar × spenneriana and Sparganium minimum). The collection in ZA is a valuable source of data about the historical and recent distribution of aquatic plants that constitute a foundation for the estimation of distribution changes, threat assessment and conservation policies.
