Ethology is the study of animal behavior. There are two specific categories of behavior: learned ad innate. Orientation behaviors place the animal in their specific environment. Animals move away from sensory input in taxis where as behavior is the response to sensory input. Stimulus’ of light, heat, moisture, sound, or chemicals are mostly found in taxis. Kinesis is the movement that does not result in orientation with stimulus. When animals respond to each other by aggressive or submissive responses, they exhibit agonistic behavior. In a complex series of activities that allow finding, courting, and mating, species exhibit mating behavior.
Methods and Materials
11a-For this experiment, you will use: 10 pillbugs, bedding material, petri dish, and filter paper.
Place the pillbugs and bedding material into a petri dish. Observe the pillbugs for 10 minutes. Prepare a choice chamber, consisting of large plastic petri dishes taped together. Line one chamber with filter paper and the other with dry filter paper. Using a soft brush, transfer 10 pillbugs from the culture into the choice chambers and cover. Count how many pillbugs are on each side of the choice chamber. Return pillbugs to stock culture. 11b-For this experiment you will use: stereoscopic microscope, vials with 3-4 virgin female Drosphila melongastor flies, and vials with 3-4 male Drosphila melongastor flies.
Set up stereoscopic microscope. Obtain one vial containing females and one with males and tap the male into the female vial. Observe behavior of flies with naked eye. Then use the microscope.

4. If you suddenly turned a rock over and found isopods under it, what would you expect them to be doing? If you watched the isopods for a few minutes, how would you expect to see their behavior change? When you lift the rock up, generally the isopods are moving around or start to move around. After a few minutes, they...
