· The concept of distribution of organisms in a resource gradient, and

· The difference between kinesis and taxis.

After doing this lab you should be able to:

· Describe some aspects of animal behavior, such as orientation behavior, agonistic behavior, dominance display, or mating behavior, and

· Understand the adaptiveness of the behaviors you studied.

1. Place ten pill bugs and a small amount of bedding material in a petri dish. Pillbugs generally do not climb, but if they do, you may cover the dish with plastic wrap or the petri dish cover.

2. Observe the pillbugs for 10 minutes. Make notes on their general appearance, movements about the dish, and interactions with each other. Notice if they seem to prefer one area over another, if they keep moving, settle down, or move sporadically. Note any behaviors that involve 2 or more pillbugs. Try to make your observations without disturbing the animals in any way. Do not prod or poke or sh

4. Use a soft brush to transfer 10 pillbugs from the stock culture into the choice chamber. Place 5 pillbugs in each side of the choice chamber. Cover the chambers.

8. Place 3 fish in a container full of regular fish tank water.

ake the dish, make loud sounds, or subject them to bright lights. You want to observe their behavior, not influence it or interfere with it.

14. In the first dish, observe the heart rate at room temperature and record the results.

19. In the sixth, add 3 drops of Potassium Hydroxide and observe and record the heart rate and reaction to the foreign substance.

21. In the final dish, add a bright light to one side of the dish with a lamp, and observe the reaction.

6. Return your pillbugs to the stock culture.

11. Once again, place the fish in three separate containers. In the first, add potassium hydroxide to make a basic solution but make it dark by covering the top. In the second, add hydrochloric acid to make an acidic solution and keep it lit. In the third, add hydrochlor
