“…Human influence on tufa deposition has been so profound during late historical times that deforestation, improved drainage and pollution are perceived as the most common causes for their depositional decline (Goudie et al, 1993;Taylor et al, 1998;Nyssen et al, 2004). Recent case studies have documented a range of anthropogenic-associated environments including Plitvice lakes -Croatia (Horvatin ci c et al, 2006), coastal tufa of the Leeuwin-Naturaliste geographic region -Western Australia (Forbes et al, 2010), Huanglong ravine and Xiangshui River -China (Liu et al, 2011;Zhang et al, 2012). In all cases, carbonate deposition rates have declined significantly as a result of phosphate pollution caused by tourism and agricultural activities within the catchment areas.…”

Traditionally, fresh water carbonate research has focused on the sedimentology and palaeontology of ancient lacustrine deposits. Lithofacies in such low-energy deposits are typically fine-grained, developed uniformly in a generally concentric distribution ('bulls-eye' pattern) and are predictable even when preserved imperfectly. In contrast, because of their local lithofacies and palaeontological complexities, fluvial carbonates were either delegated to a status of 'minor geomorphological features' or barely considered prior to the 1970s. This viewpoint was based on the depositional record of fluvial and spring-fed fresh water carbonates, which were considered to be restricted generally to localized karstic areas. Such deposits are often preserved as scattered patches of ambient temperature tufa. Occasionally, however, in active tectonic areas, localized travertine deposits are also developed from deeply circulating hydrothermal waters. With a few exceptions (for example, basins with high subsidence rates or in arid climate zones), these fresh water carbonates are prone to erosion from continuing river incision and thus may not be preserved in the geological record. A partial record of fluvial and springdeposited carbonates is often preserved in Quaternary deposits, but the record in older deposits is typically fragmentary and often diagenetically modified. Yet once their unique facies architecture (and specialized nomenclature) is understood, these carbonates provide an important record of past sedimentological cycles of great value in palaeoenvironmental landscape modelling. The emphasis of modern research is to acquire information that explains how active systems function. In this respect, tufas reveal much of how carbonate precipitation is a shared product of physico-chemical and microbiological biomediation processes. Likewise, travertines not only show an intimate interrelation with active tectonism but also hold great potential as monitors of past volcanic carbon dioxide emissions. In addition, both tufas and travertines contain palynological records that can be used as proxy indicators of climate change. Perhaps no other field of sedimentology has witnessed more developments and applications over such a brief period of study.

“…Abundance and diversity of caddisflies at tufa barriers in the Plitvice Lakes NP is controlled by the availability of food resources, variety of microhabitats (with respect to current velocity and substrate type) for larval stages (MINSHALL, 1984;HABDIJA et al, 2004;BROOKS et al, 2005;MILIŠA et al, 2006a), which is revealed by the longitudinal distribution preferences of caddisflies (GRAF et al, 2002(GRAF et al, , 2008. Thus the highest number of individuals and species were collected at the Labudovac barrier, located downstream Prošče Lake where the concentration of organic matter is among the highest within this barrage-lakes system (HORVATINČIĆ et al, 2006), providing a wide range of food resources for insect larvae (see also WARINGER, 1996;WIBERG-LARSEN et al, 2000;HABDIJA et al, 2004;MILIŠA et al, 2006a).…”

The caddisfly community composition in different microhabitats at tufa barriers was studied in the Plitvice Lakes NP, Croatia. Three tufa barriers were investigated and six emergence traps were installed at each site covering various microhabitats. Sampling was conducted monthly during the year 2008. Tufa barriers are lake outlet habitats, but they feature a variety of microhabitats similar to streams, which is reflected in the composition of caddisfly communities regarding longitudinal distribution preferences. The caddisfly communities at all three sites were dominated by species typical for the rhithral zone, but there was a shift in species composition along a longitudinal gradient, from the epirhithral to the metarhithral zone. Analysis of functional feeding guilds showed considerable differences between the caddisfly community at the Labudovac barrier and both downstream barriers, shifting from one with a quite diverse composition, to one completely dominated by passive filter-feeders. Passive filter feeders were not represented by the same taxa at up-and downstream barriers (i.e., by Hydropsyche species and Wormaldia species, at the Labudovac barrier and at both downstream barriers, respectively). Due to high complexity and habitat diversity, the highest diversity and equitability of caddisfly communities were recorded at microhabitats with particulate tufa and medium current velocity (10-20 cm/s). The lowest diversity and species richness were recorded for silt with low current velocity (0-10 cm/s). Abundance of caddisflies was positively correlated with current velocity due to a very high proportion of rheophilic passive filter feeders in the communities. However, community composition and structure is only to some degree influenced by microhabitat characteristics, but rather by their general position within the barrage-lake system, i.e., longitudinal distribution and thereby availability of different food resources. www.revhydro.comwith water from the Matica stream formed by merging of the streams Crna Rijeka and Bijela Rijeka in the upper section (Fig. 1). According to the Koppens climate classification, this area is influenced by temperate and continental climates. Most of the area is covered by forest consisting of Fagus sylvatica and Abies alba.The chosen study sites were located on three tufa barriers: Labudovac barrier (BL), Kozjak-Milanovac barrier (BKM) and Novakovića Brod barrier (BNB) (Fig. 1). Regarding general habitat characteristics, the uppermost Labudovac barrier differs from the two downstream barriers, mainly in its size (it covers a considerably larger area), substrate composition (there is no silt at BL, Table 1), annual water temperature and oxygen saturation range (the minimum and maximum water temperatures are slightly lower at BL than at BKM and BNB, and oxygen saturation values have a higher range at BL than at the two downstream barriers; IVKOVIĆ et al., 2012).

“…Qualitative mineralogical analyses have shown that dominant component of inorganic fraction of the sediment is calcite (70 − 85%) with a few percent of dolomite and quartz, and the minor components, detected in some samples, are aragonite, quartz, feldspars and minerals of the filosilicates group [9]. Calcite is mainly authigenic, i.e., it precipitates from the DIC in water.…”

“…Stable isotope ratios of 13 C/ 12 C in carbonate (δ 13 C values) depend on the carbon isotope composition of dissolved inorganic carbon (DIC) in water and the conditions under which the precipitation occurs [8]. Organic fraction in the karst lake sediments is much less abundant, only by a few percent in the Plitvice Lakes [9] but its δ 13 C values give an additional information about the processes of bioactivity and productivity in the lake waters [10][11][12].…”

Abstract:The analyses of radioactive isotopes 14 C, 137 Cs and 210 Pb, and stable isotope 13 C were performed in the sediment cores, top 40 cm, taken in 2011 from karst lakes Prošće and Kozjak in the Plitvice Lakes National Park, central Croatia. Frozen sediment cores were cut into 1 cm thick layers and dried. 14 C activity in both carbonate and organic fractions was measured using accelerator mass spectrometry technique with graphite synthesis. 137 Cs, 210 Pb, 214 Pb and 214 Bi were measured by low level gamma spectrometry method on ORTECHPGe detector with the efficiency of 32%. Distribution of 14 C activity from both lakes showed increase of the 14 C activity in the top 10 − 12 cm in both carbonate and organic fractions as a response to thermonuclear bomb-produced 14 C in the atmosphere in the sixties of the 20th century. Anthropogenically produced 137 Cs was also observed in sediment profiles. Sedimentation rates for both lake sediments were estimated based on the unsupported 210 Pb activity. Different 14 C activity of the carbonate fraction (63−80 pMC, percent of modern carbon) and organic fraction (82 − 93 pMC) is the result of geochemical and biological processes of the sediment precipitation in the lake waters. This is also confirmed by the δ 13 C values of both fractions. Carbon isotope composition, 14 C and δ 13 C , was compared with the lake sediments from the same lakes collected in 1989 and 2003. 29.30 Kv, 91.65.Dt, 91.67.Qr, 91.67.Rx, 92.20.Td, 92.20.Xy PACS (2008):
