Central-European raised bogs, developed on mountain summits, are specific ecosystems of high conservation importance, but their history remains largely unknown. Pollen, macrofossils, testate amoebae and peat characteristics were analysed in a sequence the Vozka bog (Hrubý Jeseník Mountains, Eastern Sudetes, Czech Republic). Past water chemistry water-table depths reconstructed by transfer functions calibrated from recent amoeba data long-term environmental averages. Peat initiation started...
Abstract Aim The regional co‐occurrence of contrasting bioclimatic elements (warm‐temperate, continental, boreal, arctic‐alpine) may be shaped by the distribution their glacial or post‐glacial refugia. We tested this hypothesis using pollen proxies in a region where such refugia are expected, but not unequivocally demonstrated. Location East‐Central Europe (Western Carpathians and adjacent regions). Methods compiled spectra from 112 sites distributed across various landscapes for six...
Calcareous tufas are great archives of geochemical information for the reconstruction past climate. Their importance increases in regions where other proxies rare, such as Western Carpathians. Here, we present first whole-Holocene palaeoclimatic this region based on proxies. We analysed δ 18 O, 13 C and Mg/Ca ratio tufa calcite Mituchovci site (White Carpathian Mountains, W Slovakia) compared these with pollen, plant macrofossil mollusc data. According to two distinct thermal maxima occurred...
Abstract We discovered the first peat section covering entire Holocene in Hrubý Jeseník Mountains, representing an island of unique alpine vegetation whose history may display transitional features between Hercynian and Carpathian regions. analysed pollen, plant macrofossils (more abundant bottom layers), testate amoebae upper stratigraphy chemistry. found that landscape development indeed differed from other mountains located westward. This is represented by Pinus cembra Larix during...
Observation of high-resolution terrestrial palaeoecological series can decipher relationships between past climatic transitions, their effects on ecosystems and wildfire cyclicity. Here we present a new radiocarbon dated record from Lake Fimon (NE-Italy) covering the 60-27 ka interval. Palynological, charcoal fragments sediment lithology analysis were carried out at centennial to sub-centennial resolutions. Identification best modern analogues for MIS 3 further enabled thoroughly reconstruct...
Grasslands above the timberline in European high mountains, such as Alps, have been used summer pasture for millennia, creating diverse ecosystems of conservation value. However, historical ecology natural grasslands middle mountains is much less known. We combined archival and palaeoecological sources to understand management history subalpine Hrubý Jeseník Mountains (Czechia) evaluated results view current nature efforts. The analysis showed that people managed these at least seven...
Abstract Questions How did the vegetation of a Central European mountain region with fragmented alpine zone develop during Holocene? When human land use start to alter summit grasslands? Which gradient in pollen assemblages was strongest and it consistent through time? Location Jeseníky Mountains, Czech Republic. Methods Sixteen records were subjected DCA order explore patterns compositional similarities fossil data. Because only last 6,000 years recorded study sites from summits, we...
We analysed a continuous and well-dated record of pollen, non-pollen palynomorphs, geochemistry plant macroremains from the best preserved peat bog in Bohemian-Moravian Highlands (Czech Republic). Dářko is an isolated site pine woodland dominated by central-European endemic Pinus uncinata subsp. uliginosa. It protected as National Nature Reserve Site Community Importance.We describe major patterns interesting details development this since Late Glacial provide historical context for some...
The hypothesis that Larix is a native species in the Czech Republic based on archival data. However, it has not yet been confirmed by paleoecology. In this paper we present pollen evidence of autochthonous occurrence Jeseníky Mts at four sites and systematize study records beyond region. Furthermore, provide first detailed narrative Holocene history for entire Slovakia. Mts, larch recorded since Late Glacial boundary persisted probably as part Early mixed forests until beginning Middle...
