About the book
Foraging implies the physiological mechanisms by which animals acquire and utilize available sources of energy and nutrients in a large community diversity and topographical landscape. The objective of foraging is to generate a positive energy budget for the animals to survive, grow and reproduce. Foraging hypothesis seeks to predict how animals would prefer to forage within their biophysical and social environments, based on the knowledge of nutrient availability, competition among the animals within the ecosystems, and coping with the predation risk. The major premises of the foraging are the optimal foraging theory, optimum diet models and patch selection theory put forward by the ecological scientists, which purport to explain foraging mechanisms with a purpose of positive energy balance by the organisms. The temporal and spatial foraging dynamics are driven by physiological, genetic and social factors and environmental attributes in the ecosystems. The greater understanding of the foraging behaviors can help managing herbivores including livestock species for ecological, economic and social benefits from the landscapes.
The book ‘Foraging’ intends to provide the readers and researchers recent advancements in the foraging theory, models and experimental methods, physiological and ecological factors and climatic changes determining the foraging attributes, dietary nutritional values and active compounds influencing nutrition and food selection of herbivores including livestock animals.
