Palaeoecology of Sphagnum riparium (Ångström) in Northern Hemisphere peatlands : Implications for peatland conservation and palaeoecological research

In: Review of Palaeobotany and Palynology, 2018, vol. 254, p. 1-7

Sphagnum riparium (Ångström) is a rare constituent of modern peatland plant communities and is also very rarely found as a subfossil in peat archives. We present new data on the occurrence of Sphagnum riparium macrofossils in three Northern Hemisphere peatlands from Yellowknife (NWCanada), Abisko (N Sweden), and the Northern Ural Mountains (NWRussia). Sphagnum riparium...

Effect of taxonomic resolution on ecological and palaeoecological inference : a test using testate amoeba water table depth transfer functions

Mitchell, Edward A. D ; Lamentowicz, Mariusz ; Payne, Richard J ; Mazei, Yuri

In: Quaternary Science Reviews, 2014, vol. 91, p. 62-69

Sound taxonomy is a major requirement for quantitative environmental reconstruction using biological data. Transfer function performance should theoretically be expected to decrease with reduced taxonomic resolution. However for many groups of organisms taxonomy is imperfect and species level identification not always possible. We conducted numerical experiments on five testate amoeba water table...
