“…The charophytes comprise a distinct group of macroscopic algae widely known mainly as ecosystem engineers and pioneer species [1]. Their life strategies and ecology are diverse [2][3][4] and still poorly studied for many species, especially outside Europe and Australia. Regional surveys of charophytes are an essential step toward better understanding their distribution and ecology.…”

The charophytes in many regions of the world are still poorly understood. This hampers the synthesis of distributional and ecological datasets at worldwide and continental scales, as well as complicates the generalization of species concepts for widely distributed and local taxa. To fill in the blanks for charophytes in the Caucasus and to improve our knowledge of species distribution areas in Eurasia, a field survey and study of available specimens from Dagestan (North Caucasus, Russia) was conducted based on morphological observation using light and scanning electron microscopy and molecular genetic analyses allowing for the precise identification and testing of the presence of cryptic and undescribed taxa. Nineteen new localities for seven Chara species and one Tolypella species, seven new species, and one new genus were identified in the studied region, and one new species in the Caspian Sea region was found. Some species records changed the outline or filled in the gaps in species distribution data. The presence of species distributed mainly in central Eurasia (C. globata, C. neglecta) with mainly Mediterranean–Middle Eastern species (C. gymnophylla) is notable for this region, as well as for other studied regions of the Caucasus characterized by a mixture combination of species with different distribution patterns. Chara gymnophylla was frequent in Dagestan, similar to the Mediterranean and Middle Eastern regions. Small brackish waterbodies on the coast of the Caspian Sea, freshwater mountain rivers, small associated waterbodies, and water reservoirs are the main habitats of charophytes in the studied region. Based on habitat preference and distribution in the Caucasus, recommendations for the protection of some species were suggested. The lack of endemic species among charophytes from Dagestan and Caucasus contrasts with the flora of terrestrial magnoliophytes that is rich in species endemism.

“…Chara canescens is a halophyte species which grows in brackish waters, preferably shallow. It can tolerate high light conditions and extreme ion anomalies (Blindow & Schubert 2003;Schubert et al 2016;Calero & Rodrigo 2018;Trbojević et al 2019). Epipactis purpurata is distributed in Europe from Great Britain and Denmark in the north to Italy and Greece in the south and from Spain in the west to Romania in the east.…”

“…Chara canescens Loiseleur (Charales, Charophyceae) is a small to medium-sized "brush-like" charophyte. Being the only European species of the genus with a haplostichous cortex, it is easily recognisable (Krause 1997;Mouronval et al 2015;Urbaniak & Gąbka 2015;Calero & Rodrigo 2018). A very unique peculiarity of C. canescens within the genus Chara is the occurrence of parthenogenesis, which, moreover, is just an option to sexual reproduction (Krause 1997).…”

“…Still, the ecology of this species is extremely interesting and should be further investigated, since its phenology differs depending on the seasonal environment (Calero & Rodrigo 2018). The opportunistic nature of the species (its status as an annual) is challenged by Calero & Rodrigo (2018), as well as by Blindow & Schubert (2004) and Mouronval et al (2015), who confirmed the existence of overwintering individuals. Mild temperatures during winter and autumn favour overwintering phenomena and more than one reproduction cycle in C. canescens (Calero & Rodrigo 2018).…”

This is an interesting issue that needs to be explored in the Plava Banja pond in the future, considering evident recent changes in the typical continental climate of Serbia (Vuković et al 2018).…”

Rediscovery of Chara canescens Loiseleur in Serbia

et al. 2019

Chara canescens is the only charophyte performing parthenogenetic reproduction. Although most recently found populations consist solely of parthenogenetically reproducing females, bisexual populations exist as well, making the species a unique example of the sympatric occurrence of both reproductive modes. In Serbia, C. canescens was found only once for certain, near Prokuplje in 2005. The purpose of the present study is to report a reliable new finding of C. canescens in Serbia, in a stable parthenogenetic female population. Sampling was conducted on 7 July 2018 from the Plava Banja pond near the city of Kikinda. Results of water analyses revealed high concentrations of almost all measured parameters, but especially high levels of salinity and alkalinity markers. Very high concentrations of sulphates and chlorides in the Plava Banja pond pointed to extreme ion anomalies. On the basis of the concentration of nutrients in it, the Plava Banja pond can be characterised as a eutrophic water body. Chara specimens collected from this pond were identified as C. canescens, and only females in the reproductive phase were detected. The environmental features of this habitat are typical in relation to preferences of the given species for light and salinity (ion concentration). This record is of great importance because C. canescens has been declared to be probably extinct in the wild in Serbia.
