Pinus nigra (European black pine) as the dominant species of the last glacial pinewoods in south‐western to central Iberia: a morphological study of modern and fossil pollen
Abstract Aim Our aim was to discriminate different species of Pinus via pollen analysis in order to assess the responses of particular pine species to orbital and millennial‐scale climate changes, particularly during the last glacial period. Location Modern pollen grains were collected from current...
