Material selleck chemicals in-kind support was provided by the Great Barrier Reef Marine Park Authority and Queensland Environmental Protection Agency. This research was conducted while BM was the recipient of an Australian Postgraduate Award (Industry). We thank the

following people and their organizations for samples: Kanjana Adulyanukosol, Lem Aragones, Potchana Boonyanate, John Bowen, Hans de Iongh, Nick Gales, Claire Garrigue, Caroline Gaus, Bruce Hill, Donna Kwan, Ivan Lawler, Col Limpus, David Parry, Robert Prince, Mark VanderWal, and Scott Whiting; David Savage and others at QPWS, Drs. Rachel Bowater and Steve Johnson, and others at the Queensland Department of Primary Industries Oonomba Veterinary Laboratory; Marcus Barber, Dave Holley, Duncan Limpus, James Sheppard,

and members of the Mabiaug, Badu, and Boigu communities in Torres Strait. We also thank Drs. David Hopley and Scott Smithers for advice on sea levels around Australia during the Pleistocene, Dr. John Guinotte for the sea level maps, Adella Edwards for help with figures, and Alana Grech for calculating the distances between sampling locations. Thanks also to Rod Peakall, Alexei Drummond, and Simon Ho for advice on portions of the population-genetic analyses and to Vimoksalehi Lukoschek and anonymous referees for comments on the manuscript. The High Performance Computing cluster at James Cook University made analysis in BEAST possible. Supplementary File 1 contains: Table S1.

“Department of Statistical Sciences, University of Cape Town, Rondebosch 7701, Cape Town, South Africa Animal Demography Unit, University of Cape Town, Rondebosch 7701, South Africa Habitat preference maps are a way of representing animals’ space use in two dimensions. For marine animals, the third dimension is an important aspect of spatial ecology. We used dive data from seven gray seals Halichoerus grypus (a primarily benthic forager) collected with GPS phone tags (Sea Mammal Research Unit) to investigate the distribution of the maximum depth visited in each dive. We modeled maximum dive depth as a function of spatiotemporal covariates using a generalized additive mixed model (GAMM) with individual as a random effect. Bathymetry, horizontal displacement, latitude and longitude, Julian day, sediment type, and light conditions accounted for 37% of the variability in the data. Persistent patterns of autocorrelation in the raw data suggest that individual intrinsic rhythm might be an important factor, not captured by external covariates.
