Document Summary
Meerkats: lots of behavioral interaction, herbivores, live in family groups (dens, sentinel behavior one meerkat watches for predators for every member of den. Altruistic behavior lower own fitness to benefit fitness of the other organisms. Behavioral ecology: researchers used observations of meerkats to test hypotheses about the evolution of. Other components of social behavior: fascinating behavioral adaptations are also displayed by birds, fish and even invertebrates, not all behaviors are visible. For example, animal communication may employ sounds or scents: behavior encompasses a wide range of activities. Behavior an action is carried out by muscles or glands under the control of the nervous system in response to an environmental cue. Collectively, behavior is the sum of an animal"s responses to internal and external environmental cues: behavioral ecology the study of behavior in an evolutionary context. Ultimate and proximate causes: the questions investigated by behavioral ecologists fall into two broad categories: Proximate questions concern the immediate reason for the behavior.
