摘要: Foraging consists of both ecological and physiological processes best conceived as a coordinated, whole organism process. When digestive physiology – gut structure function is rate-limiting, most animals adjust the to increase capacity. Fluctuations in resource abundances, seasonal environmental changes, aspects life cycle, like reproduction migration, cause changes diet. Such diet induce adjustment or modulation and/or permit high efficiency processing capacity response those changes. We can thus view flexible vital integral component an animal’s foraging strategy.
