Fallback Foods, Optimal Diets, and Nutritional Targets: Primate Responses to Varying Food Availability and Quality

摘要: Eating is a risky affair. All animals have to offset risks of feeding such as exposure plant toxins, increased vulnerability predation, or conspecific aggression with food's energetic and nutritional return. What, when, where an individual eats can impact fitness and, ultimately, species-level adaptations. Here, we explore the variables that influence primate preference: food availability, chemical defense, nutrient content. We present information demonstrating consumers manipulate energy intake, indicating what may be less-than-optimal for one state animal's phenotype not another. This evidence suggests factors previously assumed constraints in Optimal Foraging Theory, Functional Response, and—recently—Fallback Food models would better categorized variables. conclude “fallback” intrinsic consumer this conclusion complicates application concept ...
