Weller, D. W., Ivashchenko, Y. V., Tsidulko, G. A., Burdin, A. M. and Brownell Jr., R. L.

Western gray whales (Eschrichtius robustus) aggregate off the northeastern coast of Sakhalin Island, Russia during summer-autumn to feed on benthic and near-benthic prey. During summer 2001,...

Movement Ecology

Maresh, J., Adachi, T., Takahashi, A., Naito, Y. et al.

Background: The energy requirements of free-ranging marine mammals are challenging to measure due to cryptic and far-ranging feeding habits, but are important to quantify given the...

The Journal of Experimental Biology

Maresh, J., Simmons, S., Crocker, D., McDonald, B. et al.

Widely ranging marine predators often adopt stereotyped, energysaving behaviours to minimize the energetic cost of transport while maximizing energy gain. Environmental and anthropogenic disturbances can disrupt...

Open Access Peer Reviewed Publication

Proceedings of Meetings on Acoustics

Schwarz, L. K., E. McHuron, M. Mangel, R. S. Wells, and D. P. Costa.

Since the introduction of the population consequences of disturbance (PCoD) conceptual model, lost energy has become a central component of modelling biologically meaningful disturbance. Long-term datasets...
