Abstract

The aim of this study was to characterize the spatial and temporal variability of total organic carbon concentrations in a shallow, eutrophic lake (Lake Jaroslawieckie,the Wielkopolski National Park, mid-western Poland) against the background of lake habitat heterogeneity. The interrelations between TOC and chlorophyll a in different studied sites (in macrophyte communities as well as in open water sections) were also taken into account. In November 2000, March, May, June and July 2001, water samples were collected in two transects along and across the lake traversing macrophyte communities of the phytolittoral zonation (7 sites) and reaching the open water zone (mid-lake, 3 sites) and, additionally, in a site close to a beach attracting local inhabitants and tourists. Statistical analyses revealed significant temporal differentiation and reverse patterns of changes of both TOC and chlorophyll a concentrations in the studied lake, whereas the spatial one was not significant. No correlations between both parameters were found. The results of cluster analyses suggest macrophyte vegetation and its seasonal changes in development as the main factor to influence TOC concentrations. [ABSTRACT FROM AUTHOR]

Abstract

Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota. Generalized linear models showed that a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability. Increases in TDI were explained through a significant increase in toxin variants such as MC-YR, anatoxin and cylindrospermopsin, accompanied by a decreasing presence of MC-LR. While global warming continues, the direct and indirect effects of increased lake temperatures will drive changes in the distribution of cyanobacterial toxins in Europe, potentially promoting selection of a few highly toxic species or strains. © 2018 by the authors.
