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 ... -
Pollen-chemistry variations along elevation gradients and their implications for a proxy for UV-B radiation in the plant-fossil record
Seddon, Alistair William Robin; Festi, Daniela; Nieuwkerk, Mayke; Gya, Ragnhild; Hamre, Børge; Krüger, Linn Cecilie; Hjortland Östman, Silje Andrea; Robson, T. Matthew (Journal article; Peer reviewed, 2021)Research indicates that phenolic compounds (e.g. para-coumaric acid) found within pollen grains may be useful as a proxy to reconstruct the UV-B radiation received at the Earth's surface in the geological past. However, ... -
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 ... -
Special feature: measuring components of ecological resilience in long-term ecological datasets
Seddon, Alistair William Robin (Journal article; Peer reviewed, 2021)Ecological resilience has become a focal concept in ecosystem management. Palaeoecological records (i.e. the sub-fossil remains preserved in sediments) are useful archives to address ecological resilience since they can ... -
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 ... -
Vegetation- memory effects and their association with vegetation resilience in global drylands
Kusch, Erik; Davy, Richard; Seddon, Alistair William Robin (Journal article, 2022)Vegetation memory describes the effect of antecedent environmental and ecological conditions on the present ecosystem state and has been proposed as an important proxy for vegetation resilience. In particular, strong ...
