ARCTIC Palynological Analysis of a Peat Core from Imnavait Creek, the North Slope, Alaska

ABSTRACT. The pollen record of a 160 cm peat core from Imnavait Creek, a small upland basin in the northern foothills of the Brooks Range, Alaska, reveals a history of vegetation change from the early Holocene to the present. The Alnus rise within the region occurred after 8500 yr B.P. Betula and Cy...

Description
Summary:ABSTRACT. The pollen record of a 160 cm peat core from Imnavait Creek, a small upland basin in the northern foothills of the Brooks Range, Alaska, reveals a history of vegetation change from the early Holocene to the present. The Alnus rise within the region occurred after 8500 yr B.P. Betula and Cypemeae a ~ the major floristic elements throughout the diagram, and this, along with the significant levels of Salir and Ericaceae, sug-gest that the area was characterized by a mosaic of herb and shrub tundra communities, dependent on variations in terrain and moisture availability.
