СОВРЕМЕННОЕ СОСТОЯНИЕ ИЗУЧЕНОСТИ ВОДОРОСЛЕЙ ВОДОЕМОВ КИЕВСКОЙ ВОЗВЫШЕНОСТИ
Проанализировано современное состояние изучености разнообразия водорослей водоемов Киевской возвышености за период более чем 1,5 столетия. Отмечено видовое багатство водорослей данного региона и ее водоемов, установлена таксономическая структура с учётом номенклатурных изменений. Видовое разнообразие водорослей региона представлено 641 видом (669 вн. такс.), из 9 отделов и 257 родов. Ведущая роль пренадлежит Bacillariophyta (31,99 %), Сhlorophyta (25,86 %) и Cyanoprokaryota (14,20 %). Подчеркнута необходимость целенаправленых иследований видового разнообразия данного региона.

MODERN REVIEW OF THE STUDY OF KYIV UPLAND FRESHWATER ALGAE
The algal flora of Ukraine has been extensively studied and is now represented by 5200 species or 6300 infraspecific taxa, i.e. subvarieties of species. The most studied areas include Polissia and Forest-Steppe zone, among the least there are the Ukrainian Carpathians and Crimea. However, the factual information about central part of Forest-Steppe zone, Kyiv upland area, is either unavailable or scarce. The lack of consolidated data makes it difficult to compare the floristic composition of adjacent territories. The scope of algal studies of Kyiv upland area for the period over 1.5 centuries was analyzed. The algae diversity of investigated area was observed and the taxonomic structure with current nomenclature changes was established. The species composition of investigated area is formed by 622 species (650 infraspecies) belonging to 9 divisions and 257 genera. The obtained results made it possible to argue that Bacillariophyta (31.99 %), Сhlorophyta (25.86 %) and Cyanoprokaryota (14.20 %) divisions constitute the core of the taxonomic structure. The species diversity is represented by Nitzschia, Navicula, Pinnularia, Trachelomonas, Gomphonema, Desmodesmus, and Euglena genera. Rare and endangered algal species call for protection, thus, stressing the need for continuous study and further research in the area of algal biodiversity.
