Table 1

Use of selected keywords in abstracts (talks and posters) submitted to the first three biologging conferences. (Where appropriate, keywords were searched for in all possible forms of spelling (e.g. behaviour/behavior) and grammatical usage (i.e. as verb, adjective, adverb and noun). Results are shown as the percentage of abstracts that contained a particular keyword at least once, and trends are indicated with symbols (new, new technology; ∼, no clear trend; +, increase; −, decrease). ODBA, overall dynamic body acceleration. For further details, see tables S1 and S2 in the electronic supplementary material.)

• a This includes references to theoretical, mathematical and statistical models.

• b The authors' own judgement is accepted of what constitutes an ‘experiment’ or a ‘calibration’, respectively.

• c This only includes cases that explicitly mention ‘change’ or ‘changing’; for results of a broader search, see table S2 in the electronic supplementary material.
