Relative abundance of blue-greens is shown to have been pos. related to temp., but not to pH or total P and to have been neg. assocd. with light, mixing, NO3-, but not with NH4+, total N or total N/total P ratio. Both heterocytic and non-heterocytic groups were neg. related to NO3-. However, if Cylindrospermopsis species are considered as non-N-fixing organisms (only 10% of the filaments carried heterocytes), the lakes could be considered as dominated by non-N-fixing populations during most of the years. In this new scenario, non-N-fixing were dominant in NO3- (but not NH4+) deficient lakes, and in both NO3- and NH4+ deficient conditions. Assemblages S, Sn, H, M, X1, as groups of descriptor species of systems having similar features as proposed by Reynolds, were representative of warm, shallow, turbid, enriched and frequently mixed lakes. We propose to move some species from Z (picoplankton of oligotrophic lakes) to X1 assemblage (nanoplankton of eutrophic lakes) and we comment on Microcystis species of M assemblage from mixed shallow lakes in relation to Lm assemblage of end-summer in temperate lakes. S and Sn assemblages, which comprise species which are good-light antennae, were the best represented group in these generally turbid and shallow lakes. [on SciFinder (R)] Notes: CAN 133:271129 61-2

Resource conservation; Environmental protection; Russia, Siberia, Baykal L. Freshwater Q1 01481 Productivity; Q5 01523 Conservation, wildlife management and recreation Abstract: Lake Baikal (Russia) is the largest ancient lake in volume, containing about 20% of the Earth's surface fresh water. The water of Lake Baikal has long been considered clear, but recent observations have shown decreases in the transparency of the lake, in particular owing to phytoplankton blooms over broad areas in early spring and summer, when the lake's water is thermally stratified. Especially in summer, blooms of very small phytoplankton develop in the pelagic zone of most the lake. Additionally, massive growths of large colony-forming, nitrogen-fixing cyanobacteria such as Anabaena and Gloeotrichia, similar to those observed in highly eutrophic temperate lakes, are observed in bays into which large rivers flow. These facts suggest that the water of lake Baikal is potentially eutrophic. Because of the large amount of cold water in the hypolimnion and long retention time of the lake's water, eutrophication of Lake Baikal does not appear to be advancing rapidly. However, it is urgent to monitor the water quality of the lake and the nutrient loads from the watershed, where great social and economic changes are now taking place. The influence of eutrophication on the biological community, made up of many valuable endemic species, also has to be investigated for the protection and conservation of Lake Baikal, an invaluable natural heritage of the world .

Abstract: The effects of inorganic nutrients (P and N), organic C, and metazoan zooplankton on bacterioplankton production and abundance and on phytoplankton biomass were studied in five experiments (from May to September) in Lake Erken. In addition, the seasonal dynamics of bacterioplankton and phytoplankton were followed in the lake from April to November. Bacterioplankton production was P limited from May to August. N alone never stimulated bacterioplankton production, but bacterioplankton growth was close to colimited by P and N in July and August. Organic C stimulated bacterial production in June and September. Zooplankton enhanced bacterioplankton production in June, when bacterioplankton production was limited by P and C and the phytoplankton biomass in the lake was low. N alone stimulated phytoplankton growth in all experiments. In addition, P alone stimulated phytoplankton growth in May and July, and the combination of P and N stimulated phytoplankton growth in July and August. Zooplankton additions resulted in a decrease in phytoplankton biomass in May and September, mainly owing to grazing on Cryptophyceae. The experimental results indicate that bacterioplankton and phytoplankton growth were uncoupled during most of the open-water period because P primarily limited bacterioplankton growth and N limited phytoplankton growth. The response of the bacterioplankton community was most likely a direct effect of nutrient additions. Primary production and bacterioplankton production were correlated during the season, but partial correlations analysis indicates that this relationship can be attributed to the fact that both primary production and bacterioplankton production showed strong positive correlations with temperature. We suggest that uncoupling of bacterioplankton production and phytoplankton production may be a common phenomenon in lakes. Notes: FLA 00243590

Keywords: C$_3$, C$_4$, CAM, Community Assembly, Diversity, Photosynthetic Pathways Abstract: 1. Photosynthetic pathway diversity was evaluated for the dominant species in a seasonally aquatic community in the south-western USA using $^{14}$C pulse-chase techniques. 2. Under submerged conditions, only about half of the species were clearly C$_3$, three of the 15 dominants were CAM, one species was C$_4$ and three were potentially assimilating carbon with both C$_3$ and C$_4$ fixation. 3. During the brief terrestrial stage in the life history of these amphibious plants, both the CAM and the C$_3$ + C$_4$ species switched to C$_3$, whereas the C$_4$ species did not switch. 4. Numerous variations were apparent; for example, the C$_4$ species, while exhibiting a biochemical pathway indistinguishable from terrestrial C$_4$ plants, lacked Kranz anatomy in the aquatic foliage. Also, despite well-developed CAM in several species, others exhibited low-level diel changes in acidity, apparently not indicative of CAM. 5. Species with C$_4$ or CAM CO$_2$ concentrating mechanisms lacked the capacity for bicarbonate uptake, an alternative CO$_2$ concentrating mechanism found in certain C$_3$ species in this community. 6. Rubisco/PEPC in aquatic foliage was higher in C$_3$ species than in C$_4$, CAM or putative C$_3$ + C$_4$ species. In the terrestrial phase, as expected, the switch from CAM or C$_3$ + C$_4$ to strictly C$_3$ assimilation was associated with a substantial increase in Rubisco/PEPC. Quite unexpected, however, was the substantial increase in this ratio in terrestrial C$_3$ foliage. It is hypothesized that submerged C$_3$ plants utilize PEPC for recycling of respiratory CO$_2$ and/or C$_4$ phototrophism under field conditions of limited CO$_2$ and O$_2$ saturation, and this is lost in the terrestrial foliage.
