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…


Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean

Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
Marine Ecology Progress Series (2010)

We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…


Diel and seasonal patterns in acoustic presence and foraging behaviour of free-ranging harbour porpoises

Schaffeld, T.; Bräger, S.; Gallus, A.; Dähne, M.; Krügel, K.; Herrmann, A.; Jabbusch, M.; Ruf, T.; Verfuß, U. K.; Benke, H.; Koblitz, J. C.
Marine Ecology Progress Series (2016)

A temporal and geographical analysis of echolocation activity can give insights into the behaviour of free-ranging harbour porpoises Phocoena phocoena. Seasonal and diel patterns in the presence and foraging activity…
