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 ... -
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 ... -

We apply We apply the Rossby Centre regional climate ... -
Time to better integrate paleoecological research infrastructures with neoecology to improve understanding of biodiversity long-term dynamics and to inform future conservation
Nieto-Lugilde, Diego; Blois, Jessica L.; Bonet-García, Francisco J.; Giesecke, Thomas; Gil-Romera, Graciela; Seddon, Alistair William Robin (Journal article; Peer reviewed, 2021)Anthropogenic pressures are causing a global decline in biodiversity. Successful attempts at biodiversity conservation requires an understanding of biodiversity patterns as well as the drivers and processes that determine ...
