Introduction: Today’s arthropods include insects, spiders, centipedes, shrimp, and crawfish. They are all descendants of a single common ancestor. Arthropods are defined by having bilateral symmetry, segmented body, hard exoskeleton, jointed legs, and many pairs of limbs (“An Arthropod Checklist”). Biodiversity is the variability among living organisms from all sources. It is the diversity within species, between species, and of ecosystems. In this experiment arthropods will be collected in two different environments (“Biodiversity & Human Well-being”). One environment is near human traffic and interaction on the university’s campus and the other environment is on a field free of human traffic and interaction. The hypothesis of this experiment is that there would be more arthropods collected in the environment free of human interaction. This hypothesis should show how if human interaction interferes with an arthropods environment. Methods: The materials this experiment called for was 8 plastic cups, 8 sandwich bags, 80% isopropyl alcohol, and a small shovel. The start the experiment we labeled all of the bags and cups with numbers 1-8. The cups that were labeled 1-4 were placed in habitat 1 which was a high human

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
