Researching Biodiversity

How to Use this Passage and Waypoints

Welcome, Researcher! We've been waiting for you!

Using your Passage’s Interactive PDF, answer the questions in each section from the multimedia Waypoints.

Welcome to this interactive Reading Passage, Researching Biodiversity! Using an interactive PDF, you will use the following multimedia “Waypoints” to help guide you through an exciting journey studying monkeys and birds in the tropical rainforests of Central America.

Each Leg of a Passage has multimedia Waypoints

Pull down each leg’s menu to find the multimedia content and answer the questions in your interactive PDF. Don’t have the PDF? Ask your teacher to download Researching Biodiversity!

What’s this? In this leg of your Researching Biodiversity Interactive Reading Passage, you will be to define biodiversity and identify two countries in Central America which have tropical rainforests.

Use this interactive map and the interactive PDF to complete the answers for this Waypoint.

By the end of this leg, you will be able to explain why tropical rainforests are unique, define species richness and species abundance, and identify at least two ways humans affect biodiversity. Humans can impact biodiversity in positive ways! Introducing a very special guest, Milu. Use the interactive PDF to answer the questions from this Waypoint. Don’t have the interactive PDF?

By the end of this leg, you will be able to use scientific data to ask and answer questions about species richness and species abundance in a tropical rainforest. Don’t have the interactive PDF? Ask your teacher to download Researching Biodiversity!

Use this real-world data to complete the questions for Test #1 and Test #2 in your interactive PDF.

Test #1: Species richness is greater in the core plot than the edge plot.

Test #1: Species richness is greater in the core plot than the edge plot.


Data Collection:
Dorian collected data using 11 rectangular areas (each measuring 10m x 5m) in the core of the forest and 11 areas of the same size in the edge of the forest. In this example, one core plot has 4 species of trees in the core plot, and 3 species of trees in the edge plot. 

Analysis:
Species richness is defined as the number of different types of species found in a given area. To calculate the richness of trees in each area, compare 4 species in the core plot and 3 species in the edge plot. What plot has more species richness?

Test #2: Species abundance in the canopy is greater in the core plot than the edge plot.

Test #2: Species abundance in the canopy is greater in the core plot than the edge plot.

Data Collection:
Dorian counted the actual number of trees (abundance) for each plot. The core plot has 8 trees and the edge plot has 3 tress. 

Analysis:
To calculate the species abundance, count the number of trees per area. The core plot’s species abundance is 8 tress per 50 square meter. What is the edge plot’s?

What’s this? In this leg of your Researching Biodiversity Interactive Reading Passage, you’ll discover how easy and fun the steps of science and research really are!
