Pollen-inferred palaeoclimate reconstruction in the Alps during the Lateglacial and the early Holocene: how to estimate the effect of elevation and local parameters Export

@article{citeulike:5915871, abstract = {The modern analogue technique (MAT) was applied to six pollen sequences from the Belledonne Massif (northwestern French Alps) to estimate the effect of altitude and local parameters on pollen-based climate reconstruction during the Lateglacial and the early Holocene.
