1.What adaptations allow them to survive in their environment? List several structures and explain how the structure allows the organism to survive and thrive in its environment. You will need to do some research.
Roly-Poly bugs, also known as Armadillidium vulgare, have an exoskeleton with plates, which are used as a layer of protection. Roly-Poly bugs also use odor to defend themselves. Armadillidium vulgare are cold-blooded and sensitive to light, humidity, and quick temperature changes. They can die if left out in the sun too long. They prefer dark and moist areas.

Questions:
1. Where is the original (native) habitat of this species located?
The canary reed grass, originated in Europe, Asia, and North America.
2. How was this species first introduced into foreign habitats?
The grass was planted widely for forage and erosion control. It also spreads easily.
3. Provide at least one reason for why this species has flourished in its new habitat.
The canary reed does well in wet habitats like stream banks.
4. Provide some detail as to how this species is causing ecological harm in its introduced habitat.
The plant displaces native wetland species and can also increase flooding by clogging waterways. Reed Canary grass is invasive to native grasses that they out-compete in only 5 to 6 months of introduction.
5. List two methods used to try to control this invasive species.
The reed canary grass can be dug up, getting the root system out of the ground to prevent resprouting. Another way is if you have a big group of the grass you can burn the plant, this technique may need a few annual burnings before it becomes more controlled.
