PROBLEM:   (1) Rate of land-uplift estimated from vegetation succession data
               along transects
           (2) Does vegetation succession track the land-uplift or does it 
               lag behind?
BOOKLET:   pp 79 and Jongman et al. (1995:Exercise 5.6)
ILLUSTRATION OF:
+ a DCCA with detrending by segments
+ how to infer environmental change from the change in species composition
+ how the sample weight affects the influence of samples in environment space
