References for Integrated Habitat-Occupancy

[cheryl]

Hopefully this is appropriate for this forum. I am looking for any journal articles or reports that use the integrated habitat-occupancy model to analyze wildlife studies. Any references or pdfs are greatly appreciated.

Can you be more specific as to what you mean by "integrated habitat-occupancy model"? Occupancy models are often used for habitat use/selection analyses, but I don't understand what you mean by "integrated". Maybe someone else will know, but for the rest of us a few details wouldn't hurt.

Hi Dave,
I am referring to the multi-state "integrated habitat occupancy" model offered in the program PRESENCE, where the parameters are pi (i.e. proportion of suitable habitat- A and B being different suitability), psiA (PAO in habA), psiB (PAO in hab B). Along with this, multiyear models include parameters for habitat transition probabilities (A-A, A-B, B-B, B-A), and colonization and extinction rates for each of the transition groups.
Thank you,
Cheryl

OK, gotcha. Unfortunately, I'm no help!

Cheryl,
Hmmm, interesting question. The only reference I know about that covers this topic is in Darryl's book (page 272). I had a minute so I did a ISI search and a google scholar search and other than a few veiled references to the integrated approach which all seemed to traceback to either Presence or Darryl's book, I did not see anyone that has implemented it outright just jump out at me in the literature. I suspect Darryl or perhaps Jim H may know of a paper that has used it. Sorry I was little to no help either.

Hi Cheryl
I suspect you won't find anything (at least ones that deal with imperfect detection) as the methods paper hasn't been published yet. The revision is sitting on my desk (well, hard drive actually) waiting for me to give it a last once over before sending back to the journal.
Cheers

Hi Cheryl,

Were you able to find some references for integrated-habitat-occupancy models? I would like to model changes in detectability (rather than occupancy) as a function of landscape change (e.g. roads) between two sampling years (1994 and 2011) and was wondering if integrated-habitat-occupancy models would be a good approach. However, after reading about it in Darryl's book I am not so sure because I wouldn't be able to characterize habitat into strict categories of suitable or unsuitable. So I believe my other option is simply a multi-season model. Did you end up using the integrated-habitat-occupancy model and/or do you have any thoughts on this?

Thanks,
Sarah

Hi Sarah,
Here's the abstract of the methods paper

http://onlinelibrary.wiley.com/doi/10.1 ... x/abstract

You could use the integrated model to deal with detection also. The other option (and possibly easier if you're just getting started with all this) would be to the multi-season model and use roads etc as covariates for detection (and may be other parameters).

Cheers
Darryl
