...abundance, basal area) and the environmental variables was linear,
polinomial, or
non-linear.
My main interest in this question is that I proceeded to correct for spatial
autocorrelation (both within transects and overall) following the
procedures suggest by
Crawley 2002 for linear models
e.g. (GUAMAC = a species, CRAS = soil water retention capacity, TRANSECTO =
transect)
> model1<-gls(GUAMAC ~ CRAS)
> model2<-lme(GUAMAC ~ CRAS, random = ~ 1 | TRANSECTO)
> model3<-lme(GUAMAC ~ CRAS, random = GUAMAC ~ CRAS | TRANSECTO)
> model4<-lme(GUAMAC ~ CRAS, random = GUAMAC ~ C...
