Article Synopsis
- Researchers developed a new method to estimate the density of Antarctic krill from video footage taken by a chinstrap penguin in Antarctica, utilizing a machine learning model to identify krill in the frames.
- The model achieved a 73% overall accuracy and identified krill frames with an 83% positive predictive value, helping to analyze the foraging behavior of the penguin.
- The estimated krill density varied between 2 to 307 krill per cubic meter, providing insights into prey availability that could impact predator foraging efficiency, and this technique could be applied to other marine predators as well.
