Table 2.

Model-averaged parameter estimates and 95% confidence limits for the effects of FTYP for species/groups showing a tendency for farm-type differences. (Positive parameter estimates indicate greater density/species richness on organic farms than on conventional farms. ωi is the summed model weight for FTYP.)
