Dear list,

while analyzing animal relocations using the kselect analysis in adehabitatHS (third-order habitat selection), I would greatly appreciate any help with the following two topics:

1) How to test for significance if the relocations are not independent? Since I am working with trajectories (time interval between relocations is one hour), I am afraid I cannot use rand.kselect for this purpose?
Remark: To account for the dependence between successive relocations, I have used the BRB function to estimate the home ranges.

2) This topic deals with the visualization of the kselect results. Using plot.kselect, I get (among others) two diagrams showing a) the scores of the environmental variables (corresponding to x$l1 of the output) on the axes and b), the scores of the recentered marginality vectors on the axes (x$co). Just to be sure: Would it be mathematically correct to combine both scores into one single diagram, i.e. to create a kind of biplot?

Many thanks in advance!
