IsopodsIsopods

Terrestrial IsopodsSow bugs (Porcellio laevis) and pill bugs

(Armadillidium vulgare) Roly-polies, potato bugs, wood lice

Breathe with gills, must remain moistSimilar size, color, and life cycleDifferent Response to threats

Pill bugs- curl up in tight ball for protection Sow bugs- either flee or remain perfectly still, appearing

to be dead

Procedure- Activity 1AProcedure- Activity 1AObserve the isopods for 10 minutes.

Observe in their undisturbed behaviorNote their behavior.Did you note any agonistic behavior (social

interaction)? If so, explain the behavior.Are the movements of the isopods better

described as taxis or kinesis movements? Taxis- an innate behavioral response by an organism to a directional

stimulus or gradient of stimulus intensity EX. Chemotaxis, phototaxis, geotaxis, thermotaxis

Kinesis- like taxis, a movement or activity of an organism to a stimulus. Different from taxis in that the response to the stimulus provided is non-directional

Procedure- Activity 2AProcedure- Activity 2A Place clean filter paper into each side of the choice

chamber. Using the dropping pipet, saturate the filter paper

on one side of the chamber. Pour off any excess water; do not let the water run into the other side of the chamber or moisten the paper there.

Using the sorting brush to transfer 5 isopods to each side of the chamber. Put on the lids.

Count and record in Table 1 the number of animals on each side of the chamber, every 30 seconds for 10 minutes. Continue to record even if the isopods all move to one side or stop moving.
