Publisher Summary Foraging is a fundamental behavior that defines animals. There are many ways to forage, but many of them can be placed into the framework of optimality theory, which is not limited to foraging behavior—almost any decision can be optimized—but it has perhaps had the biggest impact there. When considering optimality and animal behavior,

In this chapter, we consider practical aspects of the foraging behaviour of insect natural enemies in its widest sense (so wide that we even include a few examples concerning non-insect arthopods, such as mites). Initially, most insect natural enemies must locate the habitat where potential victims may be found.

A TWO-STAGE TECHNIQUE FOR THE IN VITRO DIGESTION OF FORAGE CROPS
, 1963A simple technique for the determination in vitro of the dry- or organic-matter digestibility of small (0·5 g) samples of dried forages is described. It involves incubation first with rumen liquor and then with acid pepsin.

Forage quality can be assessed in terms of the animal performance that is elicited when the forage is offered to the animal. Animal performance is the product of supply, nutrient and energy concentration, intake, digestibility, and metabolism. Typically,

This chapter considers foraging behavior and its connections with learning and memory. The chapter reviews the basic models of foraging that behavioral ecologists have developed over the last 30 years. These models provide an economic framework for the study of foraging.

The literature about tannins, polyphenolic secondary metabolites of plants, with both beneficial and adverse function according to their concentration and chemical structure, is vast and often conflicting.

Are All Foragers the Same? Towards a Classification of Foragers
Sociologia Ruralis, 2021AbstractSome estimates suggest that almost a quarter of European households have members that forage, that is, pick wild products. Thus, foraging remains an important way for people to engage with their surrounding environment. Foraging has been associated both with the potential negative impacts it may have and with the potential positive effects it ...

Nutritional toxicology of tannins and related polyphenols in forage legumes.
Journal of Animal Science, 1995Proanthocyanidins (PA) (condensed tannins) and hydrolyzable tannins (HT) are the two major classes of tannins. Proanthocyanidins are flavonoid polymers.
