“…The final reconstruction was based on 5-yr running means. Identification of cysts followed Duff et al (1995), Wilkinson et al (2002) (labelled as PEARL -Paleoecological Environmental Assessment and Research Laboratory-), and Huber et al (2009) (labelled as L). The unpublished new cysts were assigned a new number using the code 'ZAB' for the fossil and modern samples of Lake _ Zabi nskie, and the code 'TSP' (Training Set Poland) for the modern samples.…”

a b s t r a c tChrysophyte cysts are recognized as powerful proxies of cold-season temperatures. In this paper we use the relationship between chrysophyte assemblages and the number of days below 4 C (DB4 C) in the epilimnion of a lake in northern Poland to develop a transfer function and to reconstruct winter severity in Poland for the last millennium. DB4 C is a climate variable related to the length of the winter. Multivariate ordination techniques were used to study the distribution of chrysophytes from sediment traps of 37 low-land lakes distributed along a variety of environmental and climatic gradients in northern Poland. Of all the environmental variables measured, stepwise variable selection and individual Redundancy analyses (RDA) identified DB4 C as the most important variable for chrysophytes, explaining a portion of variance independent of variables related to water chemistry (conductivity, chlorides, K, sulfates), which were also important. A quantitative transfer function was created to estimate DB4 C from sedimentary assemblages using partial least square regression (PLS). The twocomponent model (PLS-2) had a coefficient of determination of R 2 cross ¼ 0.58, with root mean squared error of prediction (RMSEP, based on leave-one-out) of 3.41 days. The resulting transfer function was applied to an annually-varved sediment core from Lake _ Zabi nskie, providing a new sub-decadal quantitative reconstruction of DB4 C with high chronological accuracy for the period AD 1000e2010. During Medieval Times (AD 1180e1440) winters were generally shorter (warmer) except for a decade with very long and severe winters around AD 1260e1270 (following the AD 1258 volcanic eruption). The 16th and 17th centuries and the beginning of the 19th century experienced very long severe winters. Comparison with other European cold-season reconstructions and atmospheric indices for this region indicates that large parts of the winter variability (reconstructed DB4 C) is due to the interplay between the oscillations of the zonal flow controlled by the North Atlantic Oscillation (NAO) and the influence of continental anticyclonic systems (Siberian High, East Atlantic/Western Russia pattern). Differences with other European records are attributed to geographic climatological differences between Poland and Western Europe (Low Countries, Alps). Striking correspondence between the combined volcanic and solar forcing and the DB4 C reconstruction prior to the 20th century suggests that winter climate in Poland responds mostly to natural forced variability (volcanic and solar) and the influence of unforced variability is low.

“…The terminology was further elaborated and modified by Duff et al (1995) and Wilkinson et al (2001). Since the seventies, hundreds of morphotypes have been reported from different regions in the world, such as America (Mahood & Adam 1979, Adam 1980, 1981, Adam & Mahood 1980, 1981, Adam & Mehringer 1980), Antarctic (Van de Vijver & Beyens 1997a, 1997b, 2000, Arctic (Duff et al 1995, Gilbert et al 1997, Betts-Piper et al 2004, Azores (Hansen 2001), Lake Baikal (Firsova & Likhoshway 2006), Canada (Rybak et al 1991, Duff et al 1995, Wilkinson et al 2001, Egypt (Piatek et al 2009), central Europe (Facher & Schmidt 1996;Huber et al 2009), Pyrenees (Pla 2001) and Poland (Cabala 2002, 2003, Wołowski et al 2004). The study of stomatocyst in China was just started from 2012 (Pang et al 2012a, b).…”

The Aershan National Geological Park (46–47° 39’ N, 119–121° 28’ E) characterized by volcanic landforms clusters is situated in south-west of the Great Xing’an Mountains. The investigation of chrysophycean stomatocysts was carried out based on sampling five times in this area. 171 morphotypes which were observed using scanning electron microscopy were identified and described in accordance with the guidelines of International Statospore Working Groupm (ISWG), 73 of them are new to science. It is hard to compare the stomatocysts community with that of other areas for the large number of unknown morphotypes, which indicated that amounts of study of stomatocysts morphology should be done in the whole Great Xing’an Mountains.

“…Cysts are more resistant to dissolution than chrysophyte scales and spines, preserve well in sediments; they have high paleolimnological potential in environmental reconstruction (e.g. , Vorobyova et al 1996, Kamenik et al 2001, Pla 2001, Wilkinson et al 2001, Kamenik & Schmidt 2005a, Pla & Catalan 2005, Huber et al 2009). Stomatocyst assemblages provide a sensitive biotic proxy of pH and salinity (Facher & Schmidt 1996, Pla et al 2003, Pla & Anderson 2005, and particularly they have been used to reconstruct cold-season climate variability (e.g.…”

In this study we present results of a low-resolution chrysophyte stomatocyst analysis that followed a high-resolution diatom analysis of a mountain lake sediment sequence from the Retezat Mountains, in the south Carpathians (Romania). The stomatocyst assemblages of the previously distinguished ten diatom assemblage zones of Lake Gales were studied with the aim to describe stomatocyst composition and create a taxonomical basis for detailed stratigraphical analysis in the future. We report 83 stomatocyst forms, and 7 of them are formally described here as new for science. An abrupt shift in cyst as well as diatom assemblages were recorded around 9200 cal yr BP during the 15,000 years long history of the Lake Gales. This Lake Gales event could be linked to the 9.3-ka widespread significant climatic anomaly, which was triggered by a melt water pulse into the North Atlantic.
