摘要: Detailed depth profiles of photosynthetic pigments in a sediment core (G-12) collected at the BDP93 site, Buguldeika saddle, south Lake Baikal, along with total organic carbon (TOC) and biogenic silica, were studied to elucidate temporal changes phytoplankton assemblages lake during past 28 kyr. In addition quantification carotenoids by high-performance liquid chromatography photodiode-array detection (HPLC-PDA), steryl chlorin esters (SCEs) analyzed HPLC-PDA, HPLC-mass spectrometry (LC-MS) sterols SCEs gas chromatography–mass (GC–MS) enrich taxonomical information on composition. Allochthonous input matter from Selenga River resulted higher TOC contents G-12 than previously reported (G-6) another site southern basin. The poorer correlation G-6 between chlorophyll-a-originating pigments, which are indicative autochthonous production, also indicated significant allochthonous site. abundance lutein among detected, good chlorophyll b shows that green algae represented portion phytoplankton, accompanying diatoms after last glacial period. presence cryptomonads cyanobacteria confirmed marker core. GC–MS analysis detected diatoms, algae, chrysophytes dinoflagellates. measured indicators gave consistent features for assemblage Baikal maximum.
