Does pollen-assemblage richness reflect floristic richness? A review of recent developments and future challenges
Birks, Harry John Betteley; Felde, Vivian Astrup; Bjune, Anne Elisabeth; Grytnes, John-Arvid; Seppä, Heikki; Giesecke, Thomas (Peer reviewed; Journal article, 2016-05)Current interest and debate on pollen-assemblage richness as a proxy for past plant richness have prompted us to review recent developments in assessing whether modern pollen-assemblage richness reflects contemporary ... -
July mean temperature and annual precipitation trends during the Holocene in the Fennoscandian tree-line area: pollen-based climate reconstructions
Seppä, Heikki; Birks, Harry John Betteley (Peer reviewed; Journal article, 2001)July mean temperature and annual precipipation during the last 9900 cal. yr BP were recon structed from pollen assemblages preserved in a sediment core from northern Finland. Quantitative recon structions were performed ... -

Yoshi; Tipton, John R.; Carter, Vachel A.; Brussel, Thomas; Phelps, Leanne N.; Dawson, Andria; Zanon, Marco; Vallé, Francesca; Nolan, Connor; Mauri, Achille; de Vernal, Anne; Izumi, Kenji; Holmström, Lasse; Marsicek, Jeremiah; Goring, Simon; Sommer, Philipp S.; Chaput, Michelle; Kupriyanov, Dimitry (Journal article; Peer reviewed, 2020)Fossil pollen records are well-established indicators of past vegetation changes. The prevalence of pollen across environmental settings including lakes, wetlands, and marine sediments, has made palynology one of the most ... -

(Peer reviewed; Journal article, 2014-10-22)We present quantitative reconstructions of regional vegetation cover in north-western Europe, western Europe north of the Alps, and eastern Europe for five time windows in the Holocene [around 6k, 3k, 0.5k, 0.2k, and 0.05k ... -
Regional climate model simulations for Europe at 6k and 0.2k years BP: sensitivity to changes in anthropogenic deforestation
