dear Nick,
I do not know your data, however it seems to me that the pattern of relative
abundance
of salamanders should not exhibit a sudden change, but rather a gradual change.
If this is the case, have a look to the segmented package and references

Hi Nick,
I've used MCMC to fit change point regressions to a variety of
ecological data and prefer this approach to strucchange and similar
because I feel I have more control over the model, ie. I find it
easier to tailor the form of the model to biological / demographic

do populations begin to change (either decline or increasing).
Can anyone offer suggestions on ways to go about this?
