Dear ecologgers,

Some colleagues and I are carrying out a comparative demographic analyses with 
hundreds of plant species and are interested in correlating our findings with 
abiotic factors such as mean annual temperature and precipitation, frequency of 
disturbance, or degree of abiotic stochasticity. Unfortunately we do not have 
access to these type of data for the study sites where the data in our database 
was censused. Instead, we have classified those sites following Olson et al. 
BioSci 2001's ecoregions*. We've tried to find a publication that offers global 
values for P, T, degree of disturbance, degree of stochasticity, etc at this 
ecoregion or similar classification level but have not succeeded. We would very 
much appreciate if some ecologger could suggest some references. My email 
contact is salguero AT demogr.mpg.de.

Many thanks in advance!
Rob et al.

*Olson's ecoregions are:
- Tropical and subtropical moist broadleaf forest
- Tropical and subtropical dry broadleaf forest
- Tropical and subtropical coniferous forest
- Temperate broadleaf and mixed forest
- Temperate coniferous forest
- Boreal forest/Taiga
- Tropical and subtropical grassland, savanna, and shrubland
- Temperate grassland, savanna and shrubland
- Flooded grassland and savanna
- Tundra
- Mediterranean forest, woodland and scrub
- Desert and xeric shrubland
- Mangrove
