Those models in bold elucidate mean values for each population based on diet (specialist vs. generalist) and habitat (Wellhead). Where a model consists of numerous variations (different specialisations) a ‘Pooled’ value is provided as an accumulative mean value for the model. Models for Part 1 used the four common prey species. Models for Part 2 used the common prey species and incorporating distance between sites. Models for Part 3 used the entire prey assemblage.
