Hello all,
Can someone please provide a definition for the parameters listed below which are components of the two species models. Most of the paramaters in the two species models are defined on page 232 of MacKenzie et al. (2004) however there are a couple that are not and these are:
rA (which is a component of all three paramaterisations)
rB (which is a component of the first paramaterisation)
And can someone please confirm that PsiBa refers to the probability of occupancy of species B, given the site is not occupied by species A.
Further to the above, the definitions of probability of detection parameters(excluding the two above of which I am unsure) relate to the probability of detection during the jth survey. One of my key questions is do predators affect the detection probability of prey at camera sites over each two week sampling period. In addressing this question using the 2 species models in presence, does the species interaction factor (SIF) generated from detection probabilities refer to species interactions for each survey (in my case each 24hr camera sampling period) or can it incorporate the detection history for each species over a season (season in my case being a two week sample)?
