Recent studies have shown that much of the observed spatial and temporal
variation of ecosystem fluxes can be explained and scaled by information on
soil, climate and vegetation structure, but without considering the
characteristics of the individual plants occurring at the FLUXNET sites
(e.g. Jung et al. 2010, Beer et al. 2010, Mahecha et al. 2010). Thus using the
trait data will probably give us additional information besides the
environmental and vegetation information. Also in this way we can examine the
effect of climate change on the fluxes through the influence it has on the
plants which is currently hidden by -perfect- selection of species and
adaptation of individual plants. Hence we attempt to identify the correlation
structure between relevant ecosystem functional properties, soil, climate,
vegetation and the plant traits, to understand the contribution of plant
traits to ecosystem functional properties. We will use the FLUXNET eddy
covariance data, FLUXNET ancillary data and the TRY data for information on
Ecosystem fluxes of energy, water and carbon dioxide, Climate and soil
characteristics, vegetation characteristics (LAI and abundance, at least the
dominant species), Plant traits (for at least the dominant species).
