Ants

Explain

Explain the concepts you've learned by answering these questions.

  • What was the total number of ants observed in all your quadrats?
  • What was the total number of non-ants observed in all your quadrats?
  • What is the ratio of ants to non-ants based on these totals?
  • Based on your data, is there a difference between total arthropod abundance near perches and total arthropod abundance in open areas?
  • Based on your data, do you think your study site would support a population of anoles? What could make the area more or less suitable for anoles?
  • What Proportion of ants to non-ants did you find in your samples? Round to the nearest whole number. Anoles tend to avoid distasteful ants as a prey item.
  • Based on your arthropod samples, do you think your outdoor habitat has enough prey items to support a population of anoles?

Extend

Extend your thinking about scientific sampling.

Imagine that you are a scientist interested in one of Florida's Threatened or Endangered species. Conduct some online research about one of these organisms: the red-cockaded woodpecker, smalltooth sawfish, scrub plum, or Sanibel Island rice rat. Then:

  • Describe the ecosystem this organism calls home.

  • Describe the type of habitat and resources this plant or animal needs to survive.

  • What are some other organisms within the same habitat that, together, form a community?

  • What is a research question about your chosen species you would be interested in studying?

  • You want to research the abundance of your target species in a particular area through scientific sampling. What sampling method would you choose? Why?
