Sakari; Šeirienė, Vaida; Winter, Hanna; Tzedakis, P. Chronis; Birks, Harry John Betteley (Peer reviewed; Journal article, 2019)
      The Eemian interglacial represents a natural experiment on how past vegetation with negligible human impact responded to amplified temperature changes compared to the Holocene. Here, we assemble 47 carefully selected Eemian ...

    • 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 ...

    • Evolution of vegetation and climate variability on the Tibetan Plateau over the past 1.74 million years 

      Zhao, Yan; Tzedakis, P. Chronis; Li, Quan; Qin, Feng; Cui, Qiaoyu; Liang, Chen; Birks, Harry John Betteley; Liu, Yaoliang; Zhang, Zhiyong; Ge, Junyi; Zhao, Hui; Felde, Vivian Astrup; Deng, Chenglong; Cai, Maotang; Li, Huan; Ren, Weihe; Wei, Haicheng; Yang, Hanfei; Zhang, Jiawu; Yu, Zicheng; Guo, Zhengtang (Journal article; Peer reviewed, 2020)
      The Tibetan Plateau exerts a major influence on Asian climate, but its long-term environmental history remains largely unknown. We present a detailed record of vegetation and climate changes over the past 1.74 million years ...

    • Exploring spatio-temporal patterns of palynological changes in Asia during the Holocene 

      Bhatta, Kuber Prasad; Mottl, Ondrej; Felde, Vivian Astrup; Flantua, Suzette; Birks, Hilary H; Cao, Xianyong; Chen, Fahu; Grytnes, John Arvid; Seddon, Alistair William Robin; Birks, Harry John Betteley (Journal article; Peer reviewed, 2023-05-05)
      Historical legacies influence present-day ecosystem composition and dynamics. It is therefore important to understand the long-term dynamics of ecosystems and their properties. Analysis of ecosystem properties during the ...

    • Global acceleration in rates of vegetation change over the past 18,000 years 

      Mottl, Ondrej; Flantua, Suzette; Bhatta, Kuber Prasad; Felde, Vivian Astrup; Giesecke, Thomas; Goring, Simon; Grimm, Eric C.; Haberle, Simon G.; Hooghiemstra, Henry; Ivory, Sarah J; Kuneš, Petr; Wolters, Steffen; Seddon, Alistair William Robin; Williams, John W. (Journal article; Peer reviewed, 2021)
      Global vegetation over the past 18,000 years has been transformed first by the climate changes that accompanied the last deglaciation and again by increasing human pressures; however, the magnitude and patterns of rates ...

    • A guide to the processing and standardization of global palaeoecological data for large-scale syntheses using fossil pollen 

      Flantua, Suzette; Mottl, Ondrej; Felde, Vivian Astrup; Bhatta, Kuber Prasad; Birks, Hilary H; Grytnes, John Arvid; Seddon, Alistair William Robin; Birks, Harry John Betteley (Journal article; Peer reviewed, 2023)
      Aim: Palaeoecological data are crucial for comprehending large-scale biodiversity patterns and the natural and anthropogenic drivers that influence them over time. Over the last decade, the availability of open-access ...

    • The human dimension of biodiversity changes on islands 

      Nogué, Sandra; Santos, Ana; Birks, Harry John Betteley; Björck, Svante; Castilla-Beltrán, Alvaro; Connor, Simon; de Boer, Erik J.; de Nascimento, Lea; Felde, Vivian Astrup; Fernández-Palacios, José María; Froyd, Cynthia; Haberle, Simon G.; Hooghiemstra, Henry; Ljung, Karl; Norder, Sietze J.; Peñuelas, Josep; Prebble, Matthew; Stevenson, Janelle; Whittaker, Robert J.; Willis, Kathy J.; Wilmshurst, Janet M.; Steinbauer, Manuel (Journal article; Peer reviewed, 2021)
      Islands are among the last regions on Earth settled and transformed by human activities, and they provide replicated model systems for analysis of how people affect ecological functions. By analyzing 27 representative ...
