BiomeViewer: Biodiversity and Human Impacts

Apps Student Worksheet

OVERVIEW This worksheet is designed to familiarize you with the many features found in BiomeViewer. TIPS FOR USING THE APP  You can use BiomeViewer online or download an iPad version from the App Store.  Click and hold the globe to spin it and explore different parts of the world.  Click and release a spot on the globe to drop a pin there to see a summary of the characteristics of the biome for that location.  You can also search for locations by name, latitude/longitude, or zip code.  In the biome summary panel, click on “More” to see a longer description, photos, a larger climate graph, and wildlife data.  Click on “Compare” to view details on two biomes side by side.  On the biomes legend, use the arrows at the top to see different layers including anthromes, temperature, precipitation, and terrain.  Click the gear icon to toggle gridlines and political boundaries on and off.  Click on the globe icon to switch between a spherical view and a flat projection of Earth. BIODIVERSITY AND LATITUDE 1. Drop the pin on any point in one of the biomes listed in Table 1 below and record the following: Sonoran Deseert Biome name: ____________________________ 24.8°S, 10.3° E Latitude and longitude: __________________________ 11°C Range of temperatures: Minimum __________________ 14 Range of rainfall: Minimum __________________

31°C Maximum __________________

45 Maximum __________________

128 Total number of species (richness): _________________

2. Share the data you collected with your classmates and complete Table 1 as others share their data. Pick just one representative location for each biome. Table 1. Characteristics of some representative biomes.

3. Based on the completed table, do an “I see, I think, I wonder” activity by completing Table 2. Table 2. Questions about patterns in biomes.

I see What patterns do you observe?

I see that the arid Deserts of the world all have a similar temperature and rainfall.

I think What can you infer from the patterns?

I can infer that all desert need to have a similar level of rainfall and temperature in order to stay as deserts.

I wonder What else would you like to explore?

Different biomes to see the differences in patterns.

4. Change the view to a flat map and turn on the gridlines. Click on the Sahara Desert near the Tropic of Cancer. Click “compare” and select the tropical rain forest biome in Southeast Asia at about the same latitude. Then, answer the following questions: a. How do rainfall and temperature patterns differ between the biomes?

There is subtantially more rainfall in the tropical rainforest biome with signifactly lower temperatures in comparison to the Saharan Desert

b. List the species richness for each biome. Including fauna: 800 Sahara Desert: ______________

2216 SE Asia Tropical Forest: _____________

c. Think about the difference or similarity in species richness between these two biomes. What could account for this difference or similarity?

The added rainfall and lowered temperatures in the rainfirest account for this difference, allowing more species to survive.

HUMAN IMPACTS ON BIODIVERSITY 5. Go back to your original biome from question 1. Make sure you are still in flat map view. Change to the Anthrome layer and select the year 2000. a. Select the point in your biome with the highest level of human disturbance. List the Anthromes at this location for each of these years:

Wildlands + Seminatural 1700: _________________________ Wildlands + Seminatural 1800: _________________________ Wildlands + Rangelands + Croplands 1900: _________________________

2000: _________________________ Wildlands + Rangelands + Croplands + seminatural + villages

b. Briefly summarize how humans have impacted the environment at this location over time.

Humans have impacted this location over time by changing most of the wildlands to croplands and range lands. for question c): Banner-tail kangaroo rat, black-foted ferret, Mexican long-tongued bat c. At this location, record the following: Anthrome (year 2000): _______________________ Wildlands + Rangelands + Croplands + seminatural + villages

128 Species Richness: ________________ # Species NOT listed as “Least Concern”: ___________ d. Now select the point in your biome with the lowest level of human disturbance. Ideally, it should be a wilderness area, but as close as possible to the last location. Record the following:

Wildlands Anthrome: _______________________ 105 Species Richness: ________________ None # Species NOT listed as “Least Concern”: ___________ e. Summarize the differences in species richness and IUCN status of species between the two locations. Make a claim for how human disturbance could have impacted biodiversity in your biome. Support your claim with evidence.

Human disturbance msy hsve impacted the biodiversity by endangering some of the species. While the second location was much smaller, it still had a high level of species richness, due to little human disturbance.
