From the Lab The scoop on poop and stress levels in Steller sea lions A pilot study shows that concentrations of stress hormones in the blood of animals corresponds to levels found in their feces, and that changes in the concentrations of certain thyroid hormones respond to changes in nutritional status.  <see full story>


field-t Into the Field How many juvenile coho are harbor seals eating? New technology records tag numbers of fish consumed by harbor seals, and allows the timing and location of predation events to be identified. <see full story>

September 2015 Newsletter – Issue 13

field-tInto the Field Nothing but ice all summer long Bowhead whale researchers had contingency plans for everything that might go wrong while in the field. However, they never anticipated being shut down by sea ice in summer! <see full story>


 

lab-tFrom the Lab Sea lions give up earlier when prey are scarce Researchers find that sea lions faced with reduced prey availability forage less efficiently and therefore have greater difficulty meeting daily energy requirements. <see full story>
