The question of how individuals acquire and allocate resources to maximize fitness is central in evolutionary ecology. Basic information on prey selection, search effort, and capture rates are critical for…


Harbour porpoise movement strategy affects cumulative number of animals acoustically exposed to underwater explosions

Aarts, G.; von Benda-Beckmann, A. M.; Lucke, K.; Sertlek, H. Ö.; van Bemmelen, R.; Geelhoed, S. C. V.; Brasseur, S.; Scheidat, M.; Lam, F. P. A.; Slabbekoorn, H.; Kirkwood, R.

Anthropogenic sound in the marine environment can have negative consequences for marine fauna. Since most sound sources are intermittent or continuous, estimating how many individuals are exposed over time remains…


Pile driving playback sounds and temporary threshold shift in harbor porpoises (Phocoena phocoena): Effect of exposure duration

Kastelein, Ronald A.; Helder-Hoek, Lean; Covi, Jennifer; Gransier, Robin
The Journal of the Acoustical Society of America (2016)

High intensity underwater sounds may cause temporary hearing threshold shifts (TTSs) in harbor porpoises, the magnitude of which may depend on the exposure duration. After exposure to playbacks of pile…
