We examined the relationships among vegetation, climate, fire and lake-ecosystem properties using lake sediment cores from the current northern and southern boundaries of the aspen parkland in southwestern Manitoba. We analyzed pollen, charcoal, sediment magnetics, biogenic silica, phosphorus, grain size and LOI, and dated the cores using 210Pb and 14C (AMS, calibrated). The Jones Lake record, from the southern edge of the parkland, began considerably earlier (~11 000 cal. BP) than the Mallard Pond record at the northern edge (~8600 cal. BP). These sites were characterized as prairie communities with low fire severity and relatively low lake productivity during the warm, dry period from 9000 to 6000 cal. BP. Beginning around 6500 cal. BP at Jones Lake and 3400 cal. BP at Mallard Pond, conditions appeared to get wetter as indicated by arboreal pollen percentage increases from ~30% to 40-60%, concurrent with a rise in charcoal and proxies for lake productivity (biogenic silica and percent organic phosphorus). Similar to previous studies along the prairie-forest border, we found that charcoal increased during warmer, wetter periods with increased forest cover and fuel loading rather than during warmer, drier periods of prairie dominance. Our results underscore the importance of regional changes in moisture, and its effects on lake levels and forest biomass, as a dominant control of the aspen parkland dynamic. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #--------------------------------------- # Site Information # Site_Name: Jones Lake, MB, CA # Location: Manitoba # Country: Canada # Northernmost_Latitude: 49.446389 # Southernmost_Latitude: 49.446389 # Easternmost_Longitude: -99.291111 # Westernmost_Longitude: -99.291111 # Elevation: 409 #--------------------------------------- # Data_Collection # Collection_Name: CAJLK001-CHAR # First_Year: 14611.2733396175 # Last_Year: -53.6937059881748 # Time_Unit: cal yr BP # Core_Length: # Notes: #--------------------------------------- # Species # Species_Name: # Common_Name: # Tree_Species_Code: #--------------------------------------- # Chronology_Information # Chronology: # #Short name What Units Data type #ID_DATE_INFO #ID_SITE Site ID C #CORE_NAME Name of core C #AVG_DEPTH (cm) Average depth of aged sample cm N #THICKNESS Thickness of sample cm N #ID_DATE_TYPE C #AGE_CALIB Calibrated age N #AGE_C14 Carbon-14 Age N #ERROR positive/negative error N #LAB_NUM Lab number N #ID_MAT_DATED #ID_COMMENTS C #AGE_BASIS Used for age model?
