Elephant Seal Movements: Modelling Migration*

Elephant seals migrate over vast areas of the eastern North Pacific Ocean between rookeries in Southern California and distant northern foraging areas. Several models of particle movement were evaluated and a model for great circle motion found to give reasonable results for the movement of an adult female. This model takes specific account of the fact that the movement is on the surface of a s...

Elephant Seal Movements: Some Frequency Based Studies

We studied dive patterns of northern elephant seals, that consisted of measurements of time vs. depth, by applying several time series based techniques. A primary feature of these patterns is diel variation in dive duration and maximal dive depth. Time series analysis of this variation over a two month period of continuous diving revealed an apparent cir-cadian rhythm. The consistency of this r...

Molecular population genetics of the southern elephant seal Mirounga leonina.

Southern elephant seals breed on sub-Antarctic islands and have a circumpolar distribution. We assayed mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) variation in the three main populations in the south Atlantic, south Indian, and south Pacific oceans, and a smaller continental population in South America. Population structure of mtDNA was strong and not consistent with isolation by distance....
