Boise State University Theses and Dissertations
Large vertebrate herbivores have a wide variety of browsing options available. However, most plants contain a suite of plant secondary metabolites (PSMs) that can have toxic effects when ingested. Herbivores must therefore make dietary choices that minimize the potentially harmful effects of PSM ingestion and maximize the use of available nutrients and protein. During winter months, in northern latitudes, climatological factors restrict browsing options and many populations of herbivores must subsist primarily on forage that is relatively poor in nutritional quality and high in PSMs. Many species of herbivores have developed a suite of behavioral and physiological adaptations to cope …
