focal follow data used to test theoretical predictions

individual focal follow of dolphin breathing in Doubtful Sound, Fiordland, New Zealand collected in 2000-2002. See Symons et al. for further methodological details. This data was used to carry out analyses in that paper to test changes in inter-breath interval (IBI) ("divetime") for different types of IBI ("divetype") depending on the presence of boats ("simpleboat") of individual bottlenose dolphins ("individual") for which the gender was known ("sex").
