There is a growing demand for predictive models of porpoise distribution to assess the extent of potential conflicts and to support conservation and management plans. Here, we used a range of oceanographic parameters and gen- eralised additive models to predict harbour porpoise density and to investigate seasonal shifts in por- poise distribution in relation to several static and dynamic predictors. Sightings were collected during dedicated line-transect aerial surveys conducted year-round between 2002 and 2005. Over the 4 yr, survey effort amounted to 38 720 km, during which 3887 harbour porpoises were sighted. Porpoises aggregated in distinct hot spots within their seasonal range, but the importance of key habitat descriptors varied between seasons.

  • Harbour Porpoise Habitat Preferences: Robust Spatio-Temporal Inferences from Opportunistic Data

However, data that can produce predictions with the desired precision are dif- ficult to collect, especially for species with spatially extensive and dynamic distributions. Data from platforms of opportunity could be used to complement or help design dedicated surveys, but robust inference from such data is challenging. Furthermore, regression models using static covariates may not be sufficient for animals whose habitat preferences change dynamically with season, environmental conditions or foraging strategy. More flexible models introduce difficulties in selecting parsimonious models. We implemented a robust model-averaging framework to dy - namically predict harbour porpoise Phocoena phocoena occurrence in a strongly tidal and topo- graphically complex site in southwest Wales using data from a temporally intensive platform of opportunity. Spatial and temporal environmental variables were allowed to interact in a general- ized additive model (GAM). We used information criteria to examine an extensive set of 3003 models and average predictions from the best 33.

Regional-scale patterns in harbour porpoise occupancy of tidal stream environments. – ICES Journal of Marine Science, doi:10.1093/icesjms/fsx164. Received 24 March 2017; revised 19 June 2017; accepted 25 July 2017. As harbour porpoises Phocoena phocoena are abundant within tidal stream environments, mitigating population-level impacts from tidal stream energy extraction is considered a conservation priority. An understanding of their spatial and temporal occupancy of these habitats at a regional-scale will help steer installations towards locations which maximize energy returns but reduce the potential for interactions with populations. This study quantifies and compares relationships between the presence of harbour porpoise and several hydrodynamic charac- teristics across four tidal stream environments in Anglesey, UK—a region that has been earmarked for extensive industrial development.
