Seasonal cycle of tolerance to low temperatures in three native woody plants, in relation to their ecology and post-glacial history.
The post-glacial pollen sequence for inland regions of the eastern South Island is from grass and Coprosma _ Dacrydium (probably D. bidwillii) _ Phyllocladus (probably P. alpinus) _ Podocarpus and Dacrycarpus _ Nothofagus (solandri and/or fusca). If this is interpreted simply as a response to climatic warming, the position of Dacrydium is anomalous, as at present it does not often reach altitudes as high as Phyllocladus and Nothofagus solandri var. cliffortioides.
