Isopod Behavior or The Rolly-Polly Lab Name: _____ Objectives: • Observe various aspects of a terrestrial isopod • Examine responses of isopods to various environmental factors • Learn to write good observations and make detailed biological sketches • Design and conduct an investigation of animal behavior Like their aquatic relatives, isopods get the oxygen they need to survive through gill-like structures located at the bases of their legs, rather than through lungs like most terrestrial organisms. Some isopods are much rarer than others and are kept as pets, while other common species and morphs are a great supplemental feeder. Few studies exist documenting the seasonal cycles of terrestrial isopods in North America. They are considered moderately beneficial in the sense they help break down leaves and other plant and animal remains into soil.

The most familiar isopod is probably the terrestrial pill bug (sow bug or wood louse), which can be found scurrying around any back yard in moist, dark conditions. This makes them susceptible to desiccation but allows them to absorb moisture from the air. vulgare to acute environmental stressors, these isopods (commonly identified as “pill bugs”) were exposed first to a control environment (which was created to mimic the conditions of their naturally preferred dark, damp terrestrial habitats) and then to one of five stress stimuli: heat, nitrogen fertilizer-containing soil, flooding, carbaryl insecticide, and permethrin insecticide. Optimal habitats have abundant decomposing organic matter, moderate temperatures, low illumination, and moderate to high humidity. C. Specializing in rare isopods like rubber duckies. & Hornung, E.
