High-Resolution Lacustrine Records of the Late Holocene Hydroclimate of the Sikhote-Alin Mountains, Russian Far East

چکیده
There is little information about moisture changes in different altitudinal belts mountainous regions of the southern Russian Far East. We present ecological and taxonomic compositions diatom flora identify botanical composition peat small mountain lake/mire complexes located Central Sikhote-Alin Mountains, within large landslides on paleovolcanic slopes. Frequent assemblages peat-forming plants indicate unstable hydroclimatic conditions with varying degrees wet dry up to overgrowth lakes. change sphagnum mosses trophic preferences was identified. The chronology based 11 radiocarbon dates. Accumulation rates reached 1.7–1.9 mm/year, temporal resolution for reconstructions 30–40 yr. tendencies lake evolution depended scale over last 4400 most detailed data 2600 yr were obtained from Nizhnee Lake sequence, which more sensitive climatic changes. main reason hydrological regime lakes variations precipitation during short-term sediment record fluctuations relatively well correlated regional patterns reflecting summer monsoon intensity cyclogenesis activity.

A high-resolution record of late-Holocene
35 Abstract: We reconstructed the late-Holocene surface-moisture history and vegetation dynamics of a raised bog in Michigan using testate amoebae, peat humification, pollen, stomata and plant macrofossils. Our primary objective was to compare bog palaeohydrology with the water-level history of Lake Michigan, and to regional and local vegetation changes. Hydrologic histories inferred from testa...
