Meat Only: 19 b. Tusks Only: 75 c. Meat and Tusks: 27 4. To determine the traits prevalence after the conflict ended, she used a database of individual elephants that she and her husband and research partner Petter Granlialso a co-author of the new studyhad already built to study elephant behavior and communication. In this video Dr. Joyce Poole explains a possible reason. This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

Poaching is selecting for tuskless elephants, which are more likely to survive, mate, and pass on their genes. Answers may vary. endstream endobj startxref This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes. This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem. Perri Carr describes how she uses BioInteractives elephant resources to teach concepts ranging from biotechnology to genetics to ecology and conservation. Why Do Some People with the Sickle Cell Genotype Not Have Symptoms? As you watch the videos, complete the questions from the "Task 1" handout. 254 0 obj <> endobj In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time. But the proportion of tuskless elephants has increased in some populations. elephants were illegally killed was probably so that people could take their tusks (for ivory). Africa, adaptation, Gorongosa, microevolution, scientific methodology, scientific process, selective pressure, trait. Most African . Knowledge awaits. Elephant Evolution and Adaptation. Its something I had puzzled over for so long, says Poole, co-founder and scientific director of ElephantVoices, a nonprofit science and conservation organization. It seemed simple enoughexcept we drove all day, every day for a week and didnt see a single elephant.. Learning Objectives & Practices: ERT-2.A, ERT-2.H, EIN-4.C, SP5, SP6, ELA.RST.9-12.7, ELA.WHST.9-12.1 Selection for Tuskless Elephants. In this activity, students work with authentic research data to explore the impact of poaching on African elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations. Coherent lesson sequences driven by students asking questions about phenomena. Look up the definition of the term poaching and summarize your understanding of what it means in the space below. Such a deep genetic understanding of complex evolutionary changes in large free-ranging animals would have been unobtainable just a few years ago.. Working in Gorongosa National Park, Mozambique, Dr. Joyce Poole and colleagues make a striking observation: many female elephants lack tusks. This interactive module explores how different animals elephants, birds, and bats have evolved distinct ways of using sound to communicate. Fortunately, another research team was carrying out a collaring project to track matriarch elephants. This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. Discover world-changing science. Discover tools to help plan lessons and opportunities to support professional learning. Campbell-Staton and his co-first author, Brian Arnold of Princeton, were able to join forces with the other researchers to collect blood samples from 18 femalessome with tusks and some withoutthat would meet the genomic requirements for the project. In this study, scientists used DNA profiling to determine where ivory seized from poachers had originated. Among the younger females, who were born after this period of heavy poaching, 33% are tuskless. Analyze quantitative data in order to make predictions based on evidence. Poachers, she knew, prioritized elephants with the largest tusks. 6. Like other places that had undergone intense poaching, Gorongosas female elephants exhibited an abnormally high proportion of tusklessness. This data-driven activity accompanies the video Selection for Tuskless Elephants. (The first six weeks, as well as the culminating project . 2 Resume watching the video until This activity builds on information presented in the video Selection for Tuskless Elephants.

The human immune system is made up of many cells, organs, and tissues. But why werent there any tuskless males?. This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis. endstream endobj startxref Hear how experienced science educators are using BioInteractive resources with their students. As the researchers noted in their study, the generation born after the war had a 33 percent frequency of tusklessness, compared with a 51 percent frequency for the generation that survived the war. Planarians can be used to investigate a variety of biological phenomena like animal behavior, mitosis, taxonomy, and more. In Gorongosa National Park, Poole found that among the older female elephants, who survived a period of heavy poaching in the park, over 50% are tuskless. The same high-quality resources are now available with new features, including a logged-in experience. iU This activity guides the analysis of a published scientific figure from a study that measured species population declines on a global scale.

Describe how mutations in a variety of genes can affect the development of internal and external sex characteristics. It is important to track how many elephants are left and where they live to help protect them. This pattern suggested to the researchers a sex-linked genetic origin for what they were seeing. Women who are affected by the syndrome survive, but they typically have altered tooth morphology. Total: 129 a. HHMI is investing in increasing racial, ethnic, and gender diversity in academic science to create environments in which everyone can thrive. v0E H+1Q` d Posted on 11/01/2021 by 11/01/2021 by This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history. This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest. We know we have a lot of work to do to address racial inequities in science teaching. 318 0 obj <>stream The video focused on Mozambiques Gorongosa National Park, which suffered especially heavy poaching during the Mozambican Civil War, which occurred from 1977 to 1992. Students will then analyze data to investigate the impact of human activity, namely poaching, on elephant populations. As of 2014, about 350,000 savanna elephants were living in Africa.

Teaching an Online Introductory Biology Lab Using Evolution and Ecology Resources, Why no tusks? 2. The accompanying worksheet guides students exploration. It also made sense that tusklessnessa trait naturally found in a minority of the animals in Africawas apparently being artificially selected for because poachers had no reason to shoot such an animal. This video follows Joyce Poole and other scientists working in Gorongosa National Park, Mozambique, who made the observation that many female elephants lack tusks. Articles that connect current events to BioInteractive resources. In population simulations, the researchers confirmed that it is extremely unlikely that tusklessness would have changed so drastically by chance alone. %%EOF HHMI Educator Tip Tuskless Elephants - YouTube In this video blog post, Kaitlin Bonner, an assistant professor of biology at St. John Fisher College in Rochester, NY, explains how she uses. hb```f``z' B@QKm>%QXP^miq4YtnT50WS'.*^916SqKi"%df%IE400(wt@*06sx9 g!

Researchers created the model in Figure 1 using data from cell fractionation studies. Tuskless mothers, on the other hand, had about an equal proportion of daughters with or without tusks (or, in some cases, with a single tusk). Elephants were not an obvious choice for Campbell-Staton, who has mostly focused on lizards until now. Elephant tusks are important for obtaining food and water, and essential to male elephants for competing for mates, so there is a strong natural selection for having tusks. endstream endobj 255 0 obj <. Typically, though, such studies focus on small creatures that have large population sizes and fast generational turnovers because changes they undergo are easier to observe in real time. For context, this course consisted of a three-credit lecture and a one-credit lab.
