“…This time period can be easily related to the Little Ice Age (LIA). This climatic event was identified also in lacustrine records from nearby Smreczyński Staw lake (Gąsiorowski and Sienkiewicz, 2010a) and from other lake sites in the Tatra Mountains (Kotarba, 2006;Gąsiorowski and Sienkiewicz, 2010b and references quoted herein). The LIA extended in the Tatra Mountains between the half of 14 th century and the end of 19 th century.…”

“…The palaeolimnological data suggest that the first part of this period (around AD 1350 to AD 1550) was cold but dry and the second part (AD 1550 -AD 1900) was cold and relatively humid. Particularly, the first half of 19 th century was a time of intensive precipitation (Kotarba, 2006;Gąsiorowski and Sienkiewicz, 2010a). Dendrochronological reconstructions prove that this period abounds in several years with cold summers (Bednarz, 1984;Niedźwiedź, 2004).…”

“…Therefore, it should be accumulated during a respectively long phase of cool and humid climate. Some palaeolimnological data suggest that the phase before 6 th century was relatively cold in the Tatra Mountains (Gąsiorowski and Sienkiewicz, 2010a). However, it is still little known about magnitude and time extent of this cooling.…”

Lodowa Cave in Ciemniak, which belongs to the dynamic ice cave type, contains the biggest perennial block of cave-ice in the Tatra Mountains. The ice represents congelation type, since it originates from freezing of water which infiltrates the cave. Two generations of ice have been recognized in this cave. They are divided by the distinct unconformity. The ice building both generations is layered. Two moths which were found in the younger generations were sampled and dated by 14 C method yielding 195 ± 30 and 125 ± 30 years. Bearing in mind the position in the section and the fact that the cave ice has waned since the 20s of the last century, the age is 1720-1820 AD and 1660-1790 AD respectively. It proves that the ice was formed during the Little Ice Age. Hence, the erosion boundary which underlies this generation records the degradation of ice before the Little Ice Age most probably during the Medieval Warm Period. The ice volume in the cave was substantially smaller before the Little Ice Age than it is today, despite the clear tendency to melting, which has been recognized since 20s of the last century. The older generation of ice is supposed to have its origins in a cold stage between the Atlantic period and the Medieval Warm Period.

“…1, Table 1): the Smreczyński Staw (SME), the Toporowy Staw Niżni (TSN), the Zielony Staw Gąsienicowy (ZSG), the Długi Staw (DLU), the Czarny Staw Gąsienicowy (CSG), the Wielki Staw Polski (WSP), the Przedni Staw Polski (PSP), and the Morskie Oko (MOK). This material was the basis for paleoclimatic and paleoecological reconstructions for the last two millennia (Gąsiorowski and Sienkiewicz 2010a, b). These sediments were fine and course detritus gyttja or silty mud with sand lamination and contained variable proportions of total organic carbon (TOC), from <1 % in mud and sand from the oligotrophic lakes of the alpine zone to over 50 % in the gyttja and peat from the dystrophic lakes located in the forest zone (Fig.…”

We studied the isotopic composition of organic matter in the sediments of eight mountain lakes located in the Tatra Mountains (Western Carpathians, Poland). The sediments of the lakes were fine and course detritus gyttja, mud, and sand. The total organic carbon content varied from 0.5 to 53 %. The C/N ratio indicated that in-lake primary production is the major source of the organic matter in the lakes located above the treeline, whereas terrestrial plant fragments are the major organic compounds in the sediments of dystrophic forest lakes. We also found that a clear trend of isotopic curves toward lower values of δ13C and δ15N (both ~3 ‰) began in the 1960s. This trend is a sign of the deposition of greater amounts of NOx from the combustion of fossil fuels, mainly by vehicle engines. The combustion of fossil fuels in electric plants and other factories had a smaller influence on the isotopic composition. This trend has been weaker since the 1990s. Animal and human wastes from pastures and tourism had a surprisingly minor effect on lake environments. These data are contrary to previous data regarding lake biota and suggest the high sensitivity of living organisms to organic pollution.

We examined a sediment core from a climatically sensitive High Alpine lake Unterer Giglachsee in the Niedere Tauern Alps in Austria. Our aim was to investigate long‐term climate change impacts on aquatic invertebrates (Chironomidae, Cladocera) with a special focus on the ending of the Little Ice Age and the present climate warming. Although the changes in faunal assemblages were relatively subtle through the sedimentary record, a mutual faunal breakpoint at ∼1900 AD was distinguished. In addition, the faunal dynamics correlated closely with instrumental Alpine temperature records and with reconstructed Northern Hemisphere climate development over the examined time period. In particular, significant relationships between relative taxa abundance and temperature were found with chironomids Sergentia, Paracladius, Paratanytarsus austriacus‐type, Cricotopus (I.) intersectus‐type, and Cricotopus cylindraceus‐type and with cladocerans Daphnia and Alonella excisa. Our results also suggested that the most recent assemblages represent unique community compositions. We conclude that our study lake is sensitive to climate warming and the composition of the aquatic ecosystem in Unterer Giglachsee has changed due to the impact of increasing temperatures. We predict that the further increasing temperatures will have direct but also cascading effects on the sensitive lake, potentially causing an ecosystem turnover where the key taxon Paracladius may play an important role.
