Abstract:
An annotated list of 104 cyanoprokaryota species belonging to 38 genera, 12 families, 5 orders, 3 subclasses found in the plankton of 66 water bodies (61 lakes and 5 ponds) of National Park «Valdaiskiy» in summer period 2012–2013 is given. The list is annotated by data on ecology and distribution. Taxonomic comments are provided for selected species. 14 species (marked with two asterisks — **) are recorded for the first time for Russia, 58 — for the Novgorod Region (marked with one asterisk — *), 86 — for the national park. Chroococcus minutus, Dolichospermum lemmermannii, Planktolyngbya limnetica, Snowella septentrionalis are the most widespread in the national park. Mass development was recorded for Dolichospermum lemmermannii, Microcystis viridis, M. wesenbergii, Woronichinia naegeliana. These species caused waterbloom in 14 lakes (the most abundant in lakes Korotsko, Svetloe, Plotishno, Nahodno). Planktonic species were the most frequent, but tychoplanktonic (32 %) and endophytic (8.6 %) ones also were found. In relation to salinity, freshwater (58 %) and freshwater-brackish (42 %) species were represented almost equally. With respect to the acidity most frequent were indifferent species (45 %), alkaliphilic ones were also common (35 %). Slightly more than half of species were cosmopolitan (52 %), accounted for a signifi cant portion of Holarctic species (20 %). The name of a taxon in the list is followed by arabic numerals, referring to the lake, and indications of its abundance by Cyrillic abbreviations.
