Adapted from: Click and Learn “CSI Wildlife” (2016). The Great Elephant Census gives scientists an unprecedented opportunity to gather data that will help focus conservation efforts across the continent. This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching. (Show your work.) HHMI BioInteractive Elephant Resources: Browse the full collection. According to the video, it is estimated that there are around 470,000 African elephants. It was used to make combs, pool balls, knick-knacks, and even piano keys. 10. Which elephant (there are two pages of them) matches the unidentified elephant? 10. In this interactive, you will analyze genetic evidence from two crime scenes to solve each case. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations. Name two properties of a good marker and explain why good markers are important. This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate. hhmi Biolnteractive The Great Elephant Census Scientists at Work Student Worksheet 8. To study this striking phenomenon, scientists are trying to determine the genes involved in tusk development and how variations in these genes can lead to tusklessness. Question: Hhmi BioInteractive Csi Wildlife: Using Genetics To Hunt Elephant Poachers Click & Learn Student Worksheet INTRODUCTION Forensic Scientists Collect And Analyze Scientific Evidence To Solve Crimes. DNA analysis is helping law enforcement stop the poaching of African elephants for their ivory. Elephants are a keystone species: they exert strong control on community structure and diversity relative to their population size. Learn vocabulary, terms, and more with flashcards, games, and other study tools. This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants. This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations. Additional thoughts: In a few sentences, describe how you would design an experiment to determine whether elephants can detect and interpret the calls of other elephants through the ground. Your goal is to find an exact match (which means that all the bands for all the markers are in the same positions) between the ivory sample on the far left and one of the elephants. HHMI Biointeractive Teaching Materials. This video follows Joyce Poole and other scientists working in Gorongosa National Park, Mozambique, who made the observation that many female elephants lack tusks. Our records indicate you have visited this … In … If these numbers are correct, approximately what percentage of African elephants are killed each year? HHMI Biointeractive Teaching Materials. Educator Publications: Name two properties of a good marker and explain why good markers are important. Our records indicate you have visited this interactive video on this device before. Apply what you learned from the film: 2.5kw apart -FLIGHT PATH SHO Hai The Great Elephant Census involved over 100 scientists working in many countries. 10. CSI Wildlife Explorer Worksheet. It is critically important to know how many elephants are left and where they are to guide conservation efforts. If you are returning to continue the interactive video, select “Resume.” HHMI Biointeractive Teaching Materials. Most African elephants have tusks, but some never grow them — especially in places that have a history of poaching, like Gorongosa National Park. Normally, more than 90% of female African elephants have tusks. Scientists involved in the Great Elephant Census project (founded and managed by philanthropist Paul G. Allen) are conducting aerial surveys across millions of square kilometers to obtain accurate elephant census … This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants. HHMI BioInteractive. In the first, you will compare the DNA profile of a sample of seized ivory to the DNA profiles of elephants that were killed in a park to determine if there is a match. In savannas, elephants maintain open grasslands by knocking down trees to feed on leaves and fruit.
