Hi,
On the online Early articles of the Ecography Journal you can find this paper:
Dormann et al. 2007: Methods to account for spatial autocorrelation in the analysis of species distributional data: a review. - Ecography in press (Online Early).

This article describe several methods to account for spatial autocorrelation and include an online appendix with R commands!

	Hi,
	
	I have collected data on trees from 5 forest plots located within the
	same landscape. Data within the plots are spatially autocorrelated
	(calculated using Moran's I). I would like to do a ANCOVA type of 
	analysis combining these five plots, but the assumption that there is no
	autocorrelation in the residuals is obviously violated. Does anyone have
	any ideas how to incorporate these spatial effects in my analysis? I 
	have been reading up on autoregressive techniques, but I am not sure if
	it works with more than one plot.
	
	All help is greatly appreciated!
	
	Many thanks,
	Geertje van der Heijden
