Year: 2003 Title: Holocene aquatic palynomorphs (algae and acritarchs) from Laguna Hinojales (Buenos Aires, Argentina): paleoecological interpretation Journal: Ameghiniana Volume: 40 Issue: 4 Pages: 531-544 Date: Dec 30 Accession Number: ISI:000220070400002 Keywords: palynology; algae; acritarchos; holocene; Buenos Aires; Argentina noord-holland; chlorophyta; acartiidae; morphology; eggs; prov Abstract: Holocene palynological samples from the Laguna Hinojales (37similar to 34' S; 57degrees 27' W), southeastern Buenos Aires province, contain algae (Chlorophyta, Cyanophyta and Dinoflagellata) and acritarchs. The chlorophycean algae consist of cenobia of Pediastrum musterii Tell and Mataloni, P. boryantim (Turpin) Meneghini, and Scenedesmus sp., colonies of Botryococois braunii Mitzing, zygospores of Debarya madrasensis lyengar, Motigeotia laetenvirens (Braun) Wittrock, Moitgeotia sp., Zygnenia sp. and Spirogyra spp., and spores of Desmidiaceae. Cyanophycean sheets and akinetes of Gloeotrichia sp. are well preserved. The assemblages also contain freshwater dinoflagellates, represented by a peridinioid genus. Among the acritarchs, Cobricosphaeridium spp. reach highest percentages in the lowermost part of the core, where possibly freshwater algal spores are also present. These palynomorphs, produced by organisms from plankton and benthic communities, are used as indicators of nutrient, depth and salinity changes. Variable size and salinity of the water body are inferred from fluctuating frequencies of algae and acritarchs between ca. 4,500 - 2,100 C-14 yr B.P. From 2,100 C-14 yr B.P, algal assemblages indicate a freshening of the water and a gradual transition to favourable trophic conditions in the shallow lake. Higher values of Pediastrum spp., Scenedesmus sp., and Zygnemataceae, along with low frequencies of Botryococcus braunii reflect elevated nutrient levels in a relatively shallow lake. The improvement of climatic conditions, especially an increase in average temperature, probably was responsible for the expansion of aquatic plants and natural eutrophication of the water environment. After 400 14C yr B.P. the spectrum suggests a shallow eutrophic lake. However, alternating intervals, less favourable for algae, reflect a reduction in the water body size, possibly related to periods of lower precipitation.

phosphorus; fluorescence; sediments; lakes Abstract: Weak-anion exchange chromatography was used to explore the temporal variability in the speciation of dissolved P in the surface layer of a eutrophic reservoir. Authentic free ortho-P ion was the most common form of P on three of the five sampling occasions-including during a bloom of the green algae Botryococcus braunii indicating that the bloom was not P limited. Conversely, the absence of authentic ortho-P during a bloom of the dinoflagellate Ceratium hirundinella suggested the bloom was either P limited or co-limited. These observations were confirmed by algal-growth bioassay experiments. Crown Copyright (C) 2003 Published by Elsevier Ltd. All rights reserved.

Phytoplankton were present in low to moderate abundance and generally dominated by phytoflagellates. Seasonality involved a winter abundance min., a spring diatom max., and brief increases in summer which included cyanophyta, esp. the colonial, Gloeotrichia echinulata. Some components were of benthic origin. Seasonal growth of the main phytobenthos component, Chara globularis var. virgata, regularly depleted summer lake water Ca2+ and HCO3- (alky.) by assocd. CaCO3 deposition, and a more extreme (and unusual) K+ depletion. Chem. anal. of Chara biomass and of underlying sediment indicated a large benthic nutrient stock, much surpassing that represented by phytoplankton. Growth of this biomass and the magnitude of water-borne inputs, affected Ca2+, K+, and inorg. N removals. Phytoplankton were probably limited by a low P medium, to which PO43- co-pptn. with CaCO3 may have contributed. A vernal Si depletion was probably limiting to diatom growth and appeared to be mainly induced by benthic rather than planktonic diatoms. Examples of long-term change in phytoplankton and phytobenthos compn. were noted and discussed in relation to the interaction of these components, nutrient enrichment, and possible alternative stable states.

The cyanobacterial strains exhibited distinct and diverse interspecific response mechanisms. Filtrate of Calothrix -11 was autoinhibitory, while that of Dichothrix - 371 was most inhibitory to all rivularian strains. Calothrix -121 showing maximum chlorophyll a in filtrates of five strains proved a hardy isolate. In intergeneric allelopathic studies, except Scytonema, all other non rivularian strains studied were inhibitory to the-growth of the rivularian isolates. Therefore, Scytonema may be used in BGA biofertilizer formulations to stimulate the growth of native rivularian isolates in rice fields. These results can aid in more efficient utilization of cyanobacteria.
