Macrofossil evidence of alder ( Alnus sp.) in Britain early in the Late Glacial Interstadial: implications for the northern cryptic refugia debate
ABSTRACT Wood macrofossil remains of alder and willow/poplar have been recovered from a sediment sequence in the valley of the Turker Beck in the Vale of Mowbray, North Yorkshire. These remains have yielded radiocarbon dates early in the Devensian Late Glacial (14.7–14k cal a bp ), equivalent to the...
