Chapter 4 describes how the plastic and flexible bauplan of mammals is adapted for extreme environments and extreme activities. It first examines how mammals survive in extreme cold environments, including polar regions, and then hot and dry environments, including the harshest deserts. Adaptations are described for mammals that live underground in often hypoxic, hypercapnic, and humid environments; at high altitudes in a hypoxic and cold environment; and underwater, where they must cope with extended apnoea and limited oxygen stores as well as high pressures in very deep ocean environments. How various mammals are adapted for specialized cursorial or brachiating locomotion, migration, and have occupied the aerial environment as gliders—and bats as powered fliers—is then described. Finally, the chapter explores how various mammals are able to exploit food sources that are generally difficult to digest (i.e. diets including keratin, bone, waxes, chitin, and plant cells containing cellulose, hemicellulose, and plant secondary metabolites).
