A 9600-year record of water table depth, vegetation and fire inferred from a raised peat bog, Prince Edward Island, Canadian Maritimes.

摘要: A 582-cm-long peat core was collected from Baltic Bog, an ombrotrophic peatland in north-eastern Prince Edward Island, Canada. The studied for testate amoebae, plant macrofossils, macrocharcoal, humification and organic matter content. results show that Bog first developed ∼9600 cal a BP as minerotrophic (fen) dominated by Cyperaceae. At 8200 BP, the fen transitioned into bog Sphagnum. Between 4000 water table depth (WTD) generally low surface supported trees such Picea mariana. From to 1700 WTD rose became more open. macrocharcoal period ∼2000–1000 characterized several fire events may have occurred on at site. presented this paper correspond closely with previous fossil pollen research done suggest regional climate change key factor controlling long-term variability vegetation
