摘要: Four biotic proxies (plant macrofossils, pollen, chironomids and diatoms) are employed to quantitatively reconstruct variations in mean July air temperatures (Tjul) at Lake Loitsana (northern Finland) during the Holocene. The aim is evaluate robustness biases these temperature reconstructions compare timing of highest Tjul individual reconstructions. reconstructed values evaluated relation local-scale/site-specific processes associated with Holocene lake development as factors have been shown significantly influence fossil assemblages found sediments. While pollen-based follow classical trend gradually increasing early-Holocene a mid-Holocene maximum, aquatic/wetland higher-than-present already early Holocene, that is, peak summer insolation. relatively low recorded by pollen the...
