DESCRIPTION:Many threatened marine species are highly mobile\, with dynami
 c distributions that vary in response to variation in prey availability an
 d suitable habitat. Predicting the distribution patterns of these species 
 is challenging but essential for the design of effective conservation stra
 tegies. In this seminar\, I will use two case studies to demonstrate recen
 tly developed methods for estimating and predicting dynamic distribution p
 atterns. In the first study\, the dynamic distribution of Dall’s porpois
 e (Phocoenoides dalli) is estimated from line-transect survey data using a
  Bayesian state-space model that allows the modelled population to redistr
 ibute itself over the survey season in line with the distribution of suita
 ble habitat. In the second study\, the seasonal distribution patterns of b
 eluga whales (Delphinapterus leucas) in Cook Inlet\, Alaska\, are estimate
 d from Argos telemetry data. A combination of established and newly develo
 ped methods is used to estimate the locations of tracked animals\, partiti
 on tracks into seasonal modes\, estimate seasonal movement patterns as a f
 unction of habitat covariates and predict seasonally structured utilisatio
 n densities. Both modelling approaches are broadly applicable to highly mo
 bile species in marine and terrestrial systems.\n*This talk is open to all
