Paredes, Rosana, Orben, Rachael A., Suryan, Robert M., Irons, David B., Roby, Daniel D., Harding, Ann M. A., Young, Rebecca C., Benoit-Bird, Kelly J., Ladd, Carol, Renner, Heather, Heppell, Scott, Phillips, Richard A., and Kitaysky, Alexander

Abstract:

We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla) have caused shifts in habitat use with direct implications for population trends. To test this, we compared at-sea distribution, breeding performance, and nutritional stress of kittiwakes in three years (2008–2010) at two sites in the...

An automatic and quantitative approach to the detection and tracking of acoustic scattering layers (supplemental code)

Creator:

Cade, David E. and Benoit-Bird, Kelly J.

Abstract:

Matlab code is included for detecting and tracking acoustic scattering layers from processed Echoview data. Acoustic scattering layers are ubiquitous, horizontally extensive aggregations of both vertebrate and invertebrate organisms that play key roles in oceanic ecosystems. However, currently there are no conventions or widely adaptable automatic methods for identifying these...
