We are studying how foxes and birds feed from feeders aimed at Livestock Protection Dogs in Tierra del Fuego. We want to look at time between visits to assess dependence of visits. Can anybody supply references dealing with this kind of data?

Adrían - You might try looking at the methods for analyzing temporal interactions described in these two papers. These will hopefully provide you a starting point into the literature. Best wishes - Russ

Hi Adrián,
Are you looking at ways to categorize visits as independent? or the methodology and theory of independence?
If you simply want a way to categorize visits, software managing camera trap images sometimes have this option. For example, Camelot can assess independence based on a time threshold.

Hi Adrián,
Bracis et al. {recurse} package in R allow those time between visits comparisons. I had problems running the package with my data, though.
