Thanks for reading Scientific American. Poaching is artificially selecting for tuskless elephants who can better survive, mate, and pass on their genes to the next generation. Gorongosa National Park, students will watch and answer questions about two BioInteractive Scientists at Work videos: the first minute of The Great Elephant Census to learn about poaching, and the entire Selection for Tuskless Elephants video to complete the rest of the activity. In . It is important to track how many elephants are left and where they live to help protect them. The more killing there was, the more tuskless females you got. Scientific Explanation of Evolution by Natural Selection. Poaching brings evolutionary pressure for tusklessness. Most immune cells develop from stem cells in the bone marrow. 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. But the proportion of tuskless elephants has increased in some populations. 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. In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti. One type of evidence they use is genetic data. Let's Go! Look up the definition of the term poaching and summarize your understanding of what it means in the space below. Knowledge awaits. We were going to drive around at Gorongosa, spot an elephant, see if the elephant had tusks or not, wait for the elephant to poop and then collect its DNA, he says. 0
Fortunately, another research team was carrying out a collaring project to track matriarch elephants. Resume watching the video until Elephants were not an obvious choice for Campbell-Staton, who has mostly focused on lizards until now. Using those samples, they identified candidate regions in the genome that, when mutated, seemed to explain tusklessness and its apparent male lethality.

If you're interested in using facilitated discussions to promote scientific literacy and empower students to make evidence-based decisions, this article from professor Holly Basta details how she restructured her course to promote student questioning and talk. But in males with no other X chromosome to fall back on, that mutation appears to cause death in the womb. The researchers first needed to determine whether it was actually the selection from poaching that led to a disproportionate number of tuskless individuals or if it was just some fluke of chance that emerged as the population crashed. Answers Biointeractive Hhmi - Effebi.biella.it. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations. This activity explores images of a coral bleaching event, which serve as phenomena for learning about marine ecosystems, human impacts, and climate change. This video follows Joyce Poole and other scientists working in Gorongosa National Park, Mozambique, who made the observation that many female elephants lack tusks. Poaching is selecting for tuskless elephants, which are more likely to survive, mate, and pass on their genes. As poaching in Gorongosa has been stamped out through sustained conservation efforts, the number of baby elephants born tuskless has begun to decrease. Poachers, she knew, prioritized elephants with the largest tusks. Data Points are useful resources that use figures from the primary literature and guided sets of supporting questions. 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.
