Dear ClaudioThanks for your reply ... Please, let me understand. In my study, I want to determine the trophic position of a seal in two locations and for each location, I have two baselines (benthic and pelagic), so the "posterior alpha" shown in the plot (attached) reflects the contribution of the two sources in the consumer (if this is the case, why do I have a value close to zero in a locality?, that is, do not have any contribution of baseline on this locality?) or is it a reflection of the contribution of the pelagic baseline on the benthic baseline?.Forgive me so many questions, but I want to understand the metrics of your model.Best regardsMartha
Dear MarthaThe interpretation of posterior alpha is the same, regardless of the number of species that are analyzed or plotted in the same figure: it is the relative proportion of one source vs the other for each species. If one posterior alpha distribution has a mean of 0.8, then the other source, for that species, has a mean of 0.2.CheersClaudio

Hi!Can you tell me, what is the interpretation of posterior alpha when plotting the trophic position of different localities (Location along N-S gradient)?Thank you.
