To use this document, first read the Instructions and FAQs . This document is made available by the Howard Hughes Medical Institute. Using this document, you agree to use this document in accordance with the Terms of Use . OVERVIEW This worksheet is designed to familiarize you with the many features found in BiomeViewer . NAME: VAL SEPULVEDA 1 ST P ERIOD 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: Biome name: ___ Tropical Rain Forest Amazonas, Columbia _________________________ Latitude and longitude: __(1.1*S, 72.9* W)________________________ Range of temperatures: Minimum ____ 23*C______________ Maximum _____29*C_____________ Range of rainfall: Minimum _____1075 mm_____________ Maximum _____1175mm_____________ Total number of species (richness): ____ 304 sp._____________ 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.

Based on the completed table, do an “I see, I think, I wonder” activity by completing Table 2. SKIP Table 2. Questions about patterns in biomes. I see What patterns do you observe? I think What can you infer from the patterns? I wonder What else would you like to explore? 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? In the Sahara Desert near the Tropic of Cancer, the average annual rainfall is less than 100 mm. Meanwhile, in the tropical rainforest biome in Southeast Asia, the rainfall ranges from 2000 mm to 10000 mm annually.

c. At this location, record the following: Anthrome (year 2000): ____ Rangeland ___________________ Species Richness: ___ 312 _____________ # Species NOT listed as “Least Concern”: __unknown_________ 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: Anthrome: __ seminatural _____________________ Species Richness: _ 342 _______________ # Species NOT listed as “Least Concern”: ___unknown ________ 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. In a location with high human disturbance the species richness might be lower compared to a location with low human disturbance. Human disturbance, such as habitat destruction and pollution, can directly impact biodiversity by reducing available habitats and resources for species. In the location with high human disturbance the species richness was a total of 312, while in the location with low human disturbance the total species richness was 342. Additionally, human activities can introduce invasive species, disrupt ecological processes, and contribute to climate change, all of which further impact biodiversity.
