    • Approaches to pollen taxonomic harmonisation in Quaternary palynology 

      Birks, Harry John Betteley; Bhatta, Kuber Prasad; Felde, Vivian Astrup; Flantua, Suzette; Mottl, Ondrej; Haberle, Simon G.; Herbert, Annika; Hooghiemstra, Henry; Birks, Hilary H; Grytnes, John Arvid; Seddon, Alistair William Robin (Journal article; Peer reviewed, 2023)
      Pollen taxonomic harmonisation involves the standardisation of the nomenclature of pollen and fern spores with similar morphotypes at the determination level that is common to all grains or spores with that morphotype ...

    • 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 ...

    • Inter-specific aggression generates ant mosaics in canopies of primary tropical rainforest 

      Mottl, Ondrej; Yombai, Jacob; Novotný, Vojtěch; Leponce, Maurice; Weiblen, George D.; Klimeš, Petr (Journal article; Peer reviewed, 2021)
      The ant mosaic is a concept of the non-random spatial distribution of individual ant species in trees built upon the assumption of interspecific behavioural associations. However, colony identity and environmental variance ...

    • Nutrient use by tropical ant communities varies among three extensive elevational gradients: A cross-continental comparison 

      Moses, Jimmy; Peters, Marcell K.; Tiede, Yvonne; Mottl, Ondrej; Donoso, David A.; Farwig, Nina; Fayle, Tom M.; Novotny, Vojtech; Sanders, Nathan J.; Klimes, Petr (Journal article; Peer reviewed, 2023)
      Aim: Many studies demonstrate that climate limits invertebrates along tropical elevational gradients, but we have only a rudimentary understanding of the role of nutrient limitation and climatic seasonality. Here we examined ...

    • Rate-of-change analysis in palaeoecology revisited: a new approach 

      Mottl, Ondrej; Grytnes, John Arvid; Seddon, Alistair William Robin; Steinbauer, Manuel; Bhatta, Kuber Prasad; Felde, Vivian Astrup; Flantua, Suzette; Birks, Harry John Betteley (Journal article; Peer reviewed, 2021)
      Dynamics in the rate of compositional change (rate-of-change; RoC), preserved in paleoecological sequences, are thought to reflect changes due to exogenous (climate and human forcing) or endogenous (local dynamics and ...

    • Trait-based approaches as ecological time machines: Developing tools for reconstructing long-term variation in ecosystems 

      Brown, Kerry A.; Bunting, M. Jane; Carvalho, Fabio; de Bello, Francesco; Mander, Luke; Marcisz, Katarzyna; Mottl, Ondrej; Reitalu, Triin; Svenning, Jens-Christian (Journal article; Peer reviewed, 2023)
      Research over the past decade has shown that quantifying spatial variation in ecosystem properties is an effective approach to investigating the effects of environmental change on ecosystems. Yet, current consensus among ...
