Der Mensch ist dadurch charakterisiert, dass er – als einziges Wesen – über hoch komplexe Kommunikationsformen verfügt, aber auch darauf angew- sen ist. Kommunikation für ihn als Individuum wie für

Introduction,ess. The adaptations we recognize in marine mammals today are the result of ~5 million (sea otters) to 50 million (Cetacea and Sirenia) years of evolution. This book examines adaptations that enable extant marine mammals to perform efficiently and maintain physiological homeostasis in the marine env

Return to the Sea: The Evolution of Marine Mammals,ptations that occur in living marine mammals. The dive response and enhanced oxygen stores, which increased the aerobic dive duration, and blubber for thermal insulation may have been early adaptations in each of the marine mammal lineages. The exception are fur seals and the sea otter, which rely o

Respiration and the Effects of Pressure,t enables their lungs (primarily the alveoli) to collapse under pressure. To prevent a high partial pressures of nitrogen in blood and tissues resulting in decompression sickness and nitrogen narcosis, reinforcement of the terminal airways in the lungs of pinnipeds and Cetacea allows the alveoli to

Metabolism and Thermoregulation,ay experience cold stress and exhibit a degree of heterothermy. In many seasonal breeders, the molt and reproductive cycles are interrelated but variable among species, by age classes, and geographically. Marine mammals that use blubber may have the broadest thermal neutral zone and lowest lower cri

The average minimum cost of transport (COT) for five marine mammal species is similar to the predicted mean minimum COT of quadrupedal running mammals with the same body masses. Despite differences in size, feeding ecology, and diving behavior, the rou

Physiological Adaptations for Breath-Hold Diving,creases aerobic dive duration. Hepatic and renal function along with digestion and assimilation continue during aerobic dives to maintain physiological homeostasis. Carnivorous marine mammals rely primarily on fat for ATP synthesis under resting, normoxic conditions, and during dives within their AD
