“…In the Greek part of Lake Prespa, E. canadensis was found accompanying Myriophyllum spicatum , Trapa natans , Potamogeton perfoliatus , Ceratophyllum demersum , etc. [ 45 ]. Such a list of accompanying species is in line with the high frequency of E. canadensis within the stands belonging to the vegetation of the class Potamogetonetea , as documented in Czechia [ 43 ].…”

Elodea canadensis Michx. (common waterweed) and Elodea nuttallii (Planch.) H. St. John (Nuttall’s waterweed), two invasive aquatic plants from North America, have coexisted in European water bodies since the early 20th century. New localities for both species in Croatia continued to be discovered during a study that ran from 2016 to 2023 as a part of the annual implementation of Water Framework Directive monitoring that covered the entire territory of Croatia (786 sampling points in total). Based on these data, the distribution and ecology of both species were analysed. Elodea canadensis was found at 30 sampling points, mostly in rivers, and E. nuttallii at 15 sampling points, mostly in artificial canals. Nearly three-quarters (72.5%) of all elodea sampling points were in the Pannonian Ecoregion. Elodea canadensis was discovered for the first time in the Continental—Dinaric and Mediterranean—Dinaric Subecoregions. To study the ecology of the species, for each sampling point, vegetation relevés were performed and monthly measurements of physico-chemical parameters were collected. The most common accompanying species for both elodeas are presented, and the difference in species assemblages between the sites with E. canadensis and E. nuttallii was confirmed with the ANOSIM test. Furthermore, Indicator Species Analysis revealed eight species characteristic of E. canadensis sites and eleven species characteristic of E. nuttallii sites. Fitting multivariate models (CCA and NPMR) to species abundance revealed the ecological reaction of E. canadensis and E. nuttallii to environmental descriptors. The most strongly contributing environmental descriptors that influence the distribution of both Elodea species are biochemical oxygen demand, electrical conductivity and total phosphorus. In Croatia, the replacement of E. canadensis with E. nuttallii was observed in several water bodies with high nutrient loads.

“…According to Lansdown et al (2016), it is naturalized in 10 South-Eastern European country including European Turkey. Elodea canadensis was rst collected in Greece in 2014 from the Lake Great Prespa (Poulis and Zervas 2017). It is also naturalized in different parts of Bulgaria including the Turkish border.…”

“…However, it is found in 10 South Eastern European countries (Lansdown et al 2016). Elodea canadensis herbarium specimens were rst collected from Greece in 2014 from the Lake Great Prespa located at the northwestern corner of the country (Poulis and Zervas 2017). Assyov and Petrova (2012) showed that in addition to other parts of Bulgaria, E. canadensis has a distribution along the Turkish border.…”

Submerged macrophyte Elodea canadensis Michx. is a non-native species to Turkey where it was rst recorded in 1982. In this study, we aim to provide the current distribution of E. canadensis in Turkey with notes on its invasion history and ecology. We performed eld studies to measure the physical and chemical parameters of the invaded lakes. Our study is based on new eld works, herbarium specimen examination and literature survey. As a result of our ndings, E. canadensis has invaded 15 wetlands in eight water basins of Turkey. Eleven of the invaded wetlands, including the largest freshwater lake of Turkey have protection forms ranging from national parks, nature parks to nationally/locally protected areas. Type of the wetlands are also diverse, like drainage canals, ancient pools, karstic, crater, tectonic and alluvial set lakes with trophic status from oligotrophic to eutrophic. Physico-chemical parameters measured in seven invaded wetlands are as follow: Water temperature between 15.5-22.3°C, pH between 7.1-8.6, dissolved oxygen as 3.7-8,8 mg l-1, electrical conductivity as 230-610 µS cm-1, salinity between 0.1-0.29 ppt, and ammonium as 0.25-0.74 mg l-1. The altitude range of the colonized wetlands is between sea level and 2100 m a.s.l. Elodea canadensis forms single species stands in many sites, but we could totally record 22 accompanying macrophyte taxa in species rich habitats. Here we present the most comprehensive distribution and ecology data for E. canadensis in Turkey which could be used for further research and management to understand its future spread and effect on native vegetation.

Elevational range of the colonized wetlands ranges from sea level to c. 2100 m a. s. l. Elodea canadensis forms single species stands in many sites, but we could totally record 22 accompanying macrophyte taxa in species rich habitats. Here we present the most comprehensive distribution and ecology data for E. canadensis in Turkey which, could be used for further research and management to understand its future spread and effect on native vegetation.
