  • Impact of climate change on dynamic of plant communities, lakes and swamps in Beijing area during Holocene period
  • Based on pollen analysis, charcoal fragment, C 14 radiocarbon data and loss-on-ignition (LOI), this paper analyses the plant communities in Beijing area during Holocene period. Lakes and swamps changes and plant fictional types have been discussed.

  • Does plant cover structure in rural areas modify climate change effects?
  • Atmospheric circulation ; Climatic variation ; Evapotranspiration ; Global change ; Heat flow ; Land use ; Plant canopy ; Poland ; Rural area
  • This paper shows that : modification of the plant cover in an agricultural landscape influences the vertical flux of sensible heat; the changes in land-use pattern influence the vertical fluxes of sensible and latent heat at the scale

  • Mean July temperatures during the Younger Dryas in nothwestern and central Europe as inferred from climate indicator plant species
  • The aim of this paper is to attempt a quantitative reconstruction of summer temperatures for the Younger Dryas in Europe. The AA. estimated minimum mean July temperatures from distributions of climate indicator plant species, which were
  • reconstructed from 140 pollen and plant macrofossil diagrams. The reconstructed temperatures are comparable with temperature estimates based on beetle data. However, they appear rather high when compared with estimates based on glaciological evidence.
