Most animals exhibit mysterious and unique reproductive behavior that is fundamental for production of offspring. The occurrence of reproductive behavior in animals is controlled by both inner specific physiological conditions and outer environmental signals in conjunctions with social cues. Various neuronal and humoral integrative systems play important roles in making animal reproduction successful. Recent rapid developments of biochemical, molecular, and genetic techniques have accumulated data on the molecular mechanism of reproductive behavior, such as neuronal changes in sensory nervous systems, neuroendocrine regulation by neuropeptide and neurosteroid hormones, communication of individuals by pheromones, and the interaction of animals with environmental signals. In this symposium, we focus on the animal reproductive behavior from physiological as well as biochemical points of views with special reference to evolutionally aspects from invertebrates to vertebrates. These unique reproductive behaviors of various animal species will have great contribution to open new interdisciplinary research fields in comparative physiology and biochemistry. This symposium is supported by the Japan Society for Comparative Endocrinology (JSCE).
