It points on strong increase Stankevica, 2015 of anthropogenic influence characterised by intensive metal accumulation (Zerbe et al 1999).Results of chemical analysis of Lake Velnezers sediments reflect that in the upper layer of sediments accumulated metals concentration was three times higher than in the sediments at the lake bottom.…”

These trends are observable in the change in macrofossil composition in the sediments of Lake Velnezers, where remains of damploving and wetland plants are identifiable in the 70-0cm interval, including sedges, common spike-rush, common cotton-grass, toad rush etc.…”

“…Relevancies of content and distribution of trace and major elements in the Latvian topsoils have been investigated by A. Gilucis (Gilucis 2007). Values of heavy metal accumulation in the mosses and soil have been carried out by Nikodemus and Brumelis (1998) and the highest concentrations of heavy metals (Cu, Pb, Ni, Co and Fe) have been determined in the Riga and Rezekne region (Pujāte 2015;Stankevica et al 2015). According earlier studies of lake sediments the metal concentrations in sediments of lakes in Latvia are at a background levels (Klavins et al 1995(Klavins et al , 2011.…”

Sediments in lakes have been formed under the conditions of sensitive ecosystem functions as historical records of micro-and macrocomponents. Besides others, lake sediments preserve macroremain and chemical evidence reflecting environmental changes and human impact. During the last centuries, sediment composition has been influenced by inconsistent urban and industrial developments. This article presents the multi-proxy data obtained from studies of lake sediment composition, chemical analysis and macroremain signatures in the upper sediment layer from tree small lakes of different origin: Lake Lilaste (lagoonal), Lake Velnezers (glaciokarstic), and Lake Veveri (glacial). The studies of lake sediments revealed that human impact is recognisable in the upper sediment layer of all investigated lakes, but at different depth from the sediment surface. The most recognisable traces of anthropogenic influence can be attributed to the increase of lead (Pb), cadmium (Cd) concentration, number of plant macroremains and charcoal particles in all investigated lake sediments.

Trends and events through seven centuries: the history of a wetland landscape in the Czech Republic

Environmental change can be viewed as the combined result of long-term processes and singular events. While long-term trends appear to be readily available for observation (in the form of temporal comparisons or space-for-time substitution), it is more difficult to gain information on singular events in the past, although these can be equally significant in shaping ecosystems. We examined the past 700 years in the history of a lowland wetland landscape in the Czech Republic with the help of palaeoecological, ecological, landscape archaeological, and archival data. Macrofossil and pollen data were compared to known drainage works in the area and historical climatological data. Trends and events in habitat conditions were assessed using species indicator values. Results showed that ecological succession was the general process in the study area, detected as a trend towards eutrophication, desiccation and vegetation closure. Short-term events influenced development at the sites mainly from the second half of the 19 century. This is consistent with drainage history, although bias related to sample frequency cannot be excluded. On the whole, long-term trends and discrete events were complementary on different scales. We conclude that humans facilitated and accelerated background processes, which can be most likely associated with the succession of open wetlands towards terrestrial ecosystems.
