3.1.5. HOMICIDIO EMOCIONAL
The seasonal models were much more consistent than the monthly models, both in model structure and the predicted distributions. The predicted distributions were very similar, though the visual models were slightly ‘patchier’ than the acoustic surfaces (i.e. with high predicted relative densities next to low predicted densities). As with the models in Chapter 3, a generally inshore pattern was observed in all seasonal models. The main aim of this thesis is to identify consistently important regions for harbour porpoises on the west coast of Scotland and, in terms of management and conservation, a ‘manageable’ area suitable for designation as a special area of conservation. However, from these maps it is difficult to determine any one region, because high predicted densities are observed all over the inshore regions of the west coast of Scotland and the Hebridean islands. Investigating habitat preferences and distribution at finer spatial scales by constructing ‘regional’ models is the subject of Chapter 5.
In this study, due to spatial variations in survey extent, densities were predicted for some regions in which I had little or no survey effort (e.g. The Minch and Outer Hebrides in S1). Caution must be exercised when extrapolating predictions in this way, because for any model to be used to predict for areas with no survey data, the variables must be spatially robust and the
and S2 predicted distribution surfaces and the variations in survey extent over these periods indicate that, at that these spatial scales, there are similar patterns of distribution between the regions surveyed in S1 (the Inner Hebrides) and S2 (the Inner Hebrides, plus the Minch and Outer Hebrides).
