“…Urbaniak and Gąbka [ 6 ] remarked the irregularity of the cortex, which was also noted in this study. It was already shown that the number of cortex cell rows may be variable within a genetically homogeneous Chara group [ 22 ], which may be the case in C. baueri as well.…”

Chara baueri is one of the rarest charophytes worldwide. It had been considered extinct in Europe for more than a century, from the 1870s to 2006, when it was rediscovered in Germany. The current distribution of this species is limited to a few localities in Europe (Germany, Poland and Russia), and one locality in Asia (Kazakhstan). We present a new finding of Chara baueri, to be a significant contribution to the species ecology and biogeography, and helping to review and update the current scarce knowledge. Chara baueri was discovered in Serbia and monitored for two vegetative seasons in 2018 and 2019, along with the associated macrophyte vegetation and water quality parameters. The morphology and ecology data of the species are presented comparatively with the literature data and the biogeography is critically reviewed. The population in Serbia is the first verified record of Chara baueri in southern Europe. Considering the recent findings and the knowledge accumulated in these records, Chara baueri was very possibly never extinct at all, but overlooked in Europe for the entire 20th century. We suggest that waterfowl migrating from the northern parts of Europe should be considered as the important spreading agent of Chara baueri in southern regions.

“…An exception is a case of Sava Lake, where in a recent study, only one previously detected species was reconfirmed-C. contraria, while Tolypella intricata and Nitella sp. are newly recorded [91]. Findings in Sava Lake and a nearby small lake Ada Safari [87,91] are at least intriguing, considering high anthropogenic pressure on this recreational center.…”

The shallow aquatic ecosystems of Serbia are treasuries of algal biodiversity, unfairly neglected in both scientific studies and legislation concerning species and habitat protection. Underestimating the algal diversity in these ecosystems derives primarily from poor knowledge and/or interest in algal taxonomy and phylogeny, as well as ignorance of their role in the maintenance of ecosystem equilibrium and in the bioindication of water quality. The issue of conserving algae (i.e. their habitats) is challenging due to many aspects, including the problematic biogeography concept (particularly for microalgae), low taxonomic resolution of available data, and undersampling. Still, progress in the conservation of algae is noticeable worldwide. Although macroalgae are mainly recognized as endangered and protected species, they are still overlooked in conservation management in Serbia. Simultaneously, the data on microalgal diversity in shallow and small water bodies are scarce and sporadic. There are no long term monitoring programs towards recognizing the remarkable algal diversity characteristic for these habitats. This chapter offers an overview of the biodiversity of algae-both microscopic and macroscopic in shallow and small water bodies of Serbia, along with the frame and guidelines for protecting algae and their habitats.

“…In terms of species ecology, the Slatina locality could be considered the only one typical for C. connivens in Serbia. Specimens found in the explicitly freshwater Dulin pond turned out to be genetically specific (Trbojević et al 2020) Dicranum polysetum is a calcifuge species which usually grows on the ground in forests and plantations, especially under pines and birches, in boreal and continental climates (Blockeel et al 2014). This circumpolar boreal-montane species is widespread in North, Central and Eastern Europe.…”
