Mechanics, Hydrodynamics and Energetics of Blue Whale Lunge Feeding: Efficiency Dependence on Krill Density Jan 2011 17 pages
Authors:  J A Goldbogen; J Calambokidis; E Oleson; J Potvin; N D Pyenson; G Schorr; R E Shadwick; BRITISH COLUMBIA UNIV VANCOUVER DEPT OF ZOOLOGY
The full text of this report is available for sale.Lunge feeding by rorqual whales (Balaenopteridae) is associated with a high energetic cost that decreases diving capacity, thereby limiting access to dense prey patches at depth. Despite this cost, rorquals exhibit high rates of lipid deposition and extremely large maximum body size. To address this paradox, we integrated kinematic data from digital tags with unsteady hydrodynamic models to estimate the energy budget for lunges and foraging dives of blue whales ...

The full text of this report is available for sale.We intend to quantify the biological, physical, and chemical dynamics that structure marine planktonic ecosystems. Observations of the organisms and their environment on the spatial and temporal scales that characterize their interactions, combined with models of the dominant dynamics, will lead to improved understanding of the dynamics, structure, and function of planktonic ecosystems. Our objectives in this work are to 1) visualize and quantify herbivorous copepod feeding in the laboratory, ...


Population Consequences of Acoustic Disturbance of Marine Mammals 30 SEP 2010 5 pages
Authors:  Erica Fleishman; CALIFORNIA UNIV SANTA BARBARA
The full text of this report is available for sale.The long-term goal of this project is to improve understanding of how effects of marine sound on marine mammals transfer between behavior and life functions, and between life functions and vital rates. This understanding will facilitate assessment of the population-level effects of anthropogenic sound on marine mammals. In 2005, the U.S. National Academy of Sciences convened a National Research Council (NRC) committee that examined how the behavior of marine mammals ...
