A methodological proposal for the recovery of palynomorphs from snow and ice samples
ABSTRACT The procedures for a set of techniques to recover grains of pollen 26 and spores from liquid samples are described. Liquefied samples of matrices, such as melting lakes, snow and ice, can provide a record of climatic and environmental events at different geographic and temporal scales. The...

ABSTRACT The procedures for a set of techniques to recover grains of pollen 26 and spores from liquid samples are described.
