DIETARY BALANCING ACTS: THE NUTRITIONAL GEOMETRY OF FEEDING DECISIONS IN WILDLIFE ECOLOGY

The TWS Nutritional Ecology Working Group is pleased to announce a workshop at The Wildlife Society 31st Annual Conference focused on nutritional geometry in nutritional ecology. Nutritional geometry has been used in recent studies to demonstrate that a variety of wildlife do not seek out single nutrients, but often balance and regulate multiple nutrients to meet nutritional needs. This symposium will present examples of nutritional geometry and how it is improving our understanding of nutritional ecology. For more information click here!
