GGC Hypotheses, Outline, Datasources
Please edit at will!
Hypothesis: Global grassland communities (GGCs) are 'structured' similarly.
Predictions:
GGCs should occupy similar trait space worldwide - if not, does trait
space vary with: latitude, precipitation, PET, nativity (proportion of
species or biomass that is native vs. non-native), land use history
(intact vs. abandoned), or grazing pressure?
Is there a prediction for phylogenetic structure? For species diversity?
Data needs: community, trait, environmental data. In addition to DGS sources we might use: China grasslands data, European sites with LEDA trait data, ...
Dangers: Available trait data may be too coarse to detect differences, ie Scott's example of two similar bunch grasses, one of which has taken off while the other has not.
