The paleoenvironmental and cultural impacts of this Late-Holocene climate variability have been analyzed intensively in the western Caribbean, and to a lesser extent in the southern Caribbean. However, the occurrence and impacts of Late Holocene climate shifts in the eastern Caribbean, especially in island interiors, has not been well documented. Here we present sediment records of Late-Holocene paleoenvironmental change from two lakes located on the Caribbean slope of the Cordillera Central in the Dominican Republic that span the last ~3000 years. Sediment characteristics, pollen, charcoal, biogenic carbonate assemblages and isotopic composition, and bulk sedimentary carbon isotope values in Laguna Castilla and Laguna de Salvador indicate extreme shifts in hydrology, vegetation, and disturbance regimes in response to climate change and human activity in the lake watersheds. Close correspondence between the hydrological histories of the lakes and trace metal concentrations in sediments of the Cariaco Basin indicate that precipitation variability here responds to the same controls, and may similarly reflect shifts in the mean annual position of the ITCZ. Human occupation of the watersheds appears to be closely linked to severe dry periods and may indicate larger scale cultural responses to precipitation variability on the island of Hispaniola. Prehistoric human populations strongly affected vegetation and disturbance regimes in the lake watersheds. Impacts may have lasted several centuries and may have been more severe than impacts of modern populations. #------------------ # Funding_Agency # Funding_Agency_Name: National Geographic Society # Grant: #------------------ # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: BCS-0550382, EAR-0004104 #------------------ # Funding_Agency # Funding_Agency_Name: Association of American Geographers # Grant: #------------------ # Site_Information # Site_Name: Laguna de Felipe # Location: Ocean>Atlantic Ocean>North Atlantic Ocean>Caribbean Sea>Dominican Republic # Country: Dominican Republic # Northernmost_Latitude: 18.8 # Southernmost_Latitude: 18.8 # Easternmost_Longitude: -70.88 # Westernmost_Longitude: -70.88 # Elevation: 1005 m #------------------ # Data_Collection # Collection_Name: LagunaDeFelipe2.Lane.2009 # Earliest_Year: 1353.284 # Most_Recent_Year: -40.228 # Time_Unit: Cal Year BP # Core_Length: # Notes: #------------------ # Chronology: # #------------------ # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components ( 10 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data, additional_information) # ## age_CE age, , , year CE, , , , ,N, ## age_calBP age, , , calendar years before present, , , , ,N, ## d18O_ostracodes delta 18O, ostracod, ,permil VPBD, , paleolimnology, ,,N, oxygen isotopes from Adult Cythridella boldii ostracod valves ## d13C_ostracodes delta 13C, ostracod, ,permil VPBD, , paleolimnology, ,,N, carbon isotopes from Adult Cythridella boldii ostracod valves # #------------------ # Data: # Data lines follow (have no #) # Data line format -
