Animals don't forage randomly and have to make decisions continuously about nutrients and toxins in their food. How do they make decisions when the environment is so variable and when they also have to consider predators and social interactions?
Animals have to be able to recognize impending toxicosis and change their feeding behaviour promptly. To do so they need to monitor the consequences of the meal continuously and then to be able to translate this feedback into changes in feeding behaviour. Physiology and behaviour come together in every mouthful and we are interested in the nature and the consequences of feedback signals that animals use and how these shape animal feeding.
