However, because the whooping cranes imprinted on their foster parents, none formed a pair-bond strong attachment with a whooping crane mate. What special challenges did researchers face in order to return whooping cranes to the wild? What would you have to wear if you worked with hatchlings? Scientists tried raising whooping cranes in captivity by using sand hill cranes as foster parents. Lorenz found that when incubator-hatched goslings spent their first few hours with him rather than with a goose, they imprinted on him and showed no recognition of their biological mother or of adults of their own species. Sensitive period-a limitted phase in an animal's development that is the only time when certain behviors can be learned Describe the classic study of parental imprinting done by Konrad Lorenz. Tying Shoes Strings What is meant by fitness? How can habituation increase fitness? The loss of responsiveness to stimuli that convey little or no information Describe the process of imprinting, and explain what is meant by sensitive or critical period. Innate behavior is behavior that is developmentally fixed and under strong genetic control Ex.Ĭrying vs. Concept What is the difference between innate and learned behavior? Give an example of each. Notice also the different types of questions that might be studied by an ecologist at each level of study. It shows the different levels of the biological hierarchy studied by ecologists. They can transmit information about sex, social order, and alarm signals. What is ecology Ecology is the scientific study of the interactions between organisms and the environment. Pheromones are chemical substances emitted by animals that are used to communicate through odors or taste with members of their own species. What are pheromones? Give three specific types of information that can be transmitted through pheromones. The angle of the straight run relative to the hives vertical surface is the same as the horizontal angle of the food in relation to the sun.
This dance, consisting of a half-circle swing in one direction, a straight run during which the bee waggles its abdomen, and a half-circle swing in the other direction, communicates to the follower bees both the direction and distance of the food source in relation to the hive. When the food source is farther from the nest, the returning bee instead performs a waggle dance.
