The effect of different photoperiods: 24 h illumination and a 12:12-h light/dark (12L:12D) cycle on the growth rate biomass productivity was studied in five algal species: Neochloris conjuncta, terrestris, texensis, Botryococcus braunii Scenedesmus obliquus. green microalgae examined differ reproduction mode. Continuous stimulated B. S. obliquus more effectively than microalgal species from genus Neochloris. However, under shorter duration light same intensity (12L:12D cycle), all three...
Abstract To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across Mediterranean, Continental, Boreal climatic zones European continent. Multilinear regression models tested on this snapshot mostly eutrophic (median total phosphorus [TP] = 0.06 nitrogen [TN] 0.7 mg L −1 ), its subsets (2 depth types 3 zones), show that light climate stratification strength were most significant explanatory variables for...
Cyanobacterial blooms in eutrophic water bodies are a worldwide problem. Combined effects of mixtures secondary metabolites produced by different cyanobacterial species on aquatic fauna still not well recognised. We compared the survivorship Brachionus calyciflorus Pallas (Rotifera) and Daphnia pulex Leyding (Cladocera) exposed to pure microcystin LR (MC-LR), anatoxin-a (ANTX) five extracts obtained from bloom-forming cyanobacteria Microcystis, Planktothrix Dolichospermum. The results...
Water blooms formed by cyanobacteria that produce various toxins, such as hepatotoxic microcystins (MCs), neurotoxic anatoxin-a (ANTX) etc. (Carmichael, 1992;Welker & Döhren, 2006), which may affect aquatic organisms at levels in the food chain (Ferrão-Filho Kozlowsky-Suzuki, 2011).The sensitivity of hydrobionts to exposure cyanotoxins differs greatly.There is little information on effect cyanobacterial toxins benthic insect larvae, Chironomus spp., are widespread and abundant eutrophic...
Abstract Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers numerous services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution climate-change induced stressors, like poor transparency, increased water temperature enhanced stratification....
Abstract A four-year study carried out in a lake with perennial water blooms caused by toxigenic Planktothrix agardhii (Oscillatoriales) and Anabaena lemmermanii, flos-aquae, spp. Aphanizomenon issatchenkoi (Nostocales) revealed that the lake-dwelling fish were threatened simultaneous exposure to intracellular extracellular microcystins (MCs) as well anatoxin-a (ANTX). Higher contents of found livers than muscles. This is first report on ANTX accumulation common fish, indigenous European...
Summary The main aims of this paper are to investigate: if widespread lichen species ( Xanthoria parietina , Physconia grisea and Physcia adscendens collected in Italy Poland) exposed cadmium (Cd), lead (Pb) zinc (Zn) synthesize phytochelatins; whether phytochelatins synthesized by the heterotrophic fungus (mycobiont) or photosynthetic alga (photobiont), both partners; there significant differences phytochelatin production same growing at different latitudes. In lichens investigated, Cd, Pb...
Temporal and spatial variation in the concentrations of intra- extra-cellular microcystins were studied a hypertrophic lake with bloom Planktothrix agardhii (Gomont) Anagnostidis et Komarek. Concomitantly increase water temperature (from 2 to 20 °C) abundance P. increased from 1.9 x 105 4.3 107 trichomes L-1. In autumn, spite lower (14°C) than summer it was still very high. Mass development (to 6 106 L-1 higher) caused severe decrease transparency 0.5 - 0.2 m summer/autumn). The...
