Summary
Animal species have been going extinct since the dawn of time – which begs the questions: why is it happening, and which ones are next? Professor Corey Bradshaw joins the podcast to address this interesting research topic and convey his perspective as a global-change ecologist.
Corey is the Matthew Flinders Professor of Global Ecology at Flinders University where he studies how human endeavor and climate fluctuations have altered past, present, and future ecosystems. Using methods such as species extinction modeling, Corey is uncovering just how much deforestation has occurred as a result of rapid urbanization and increasing agricultural intensification…
Jump in now to discover:
- How humans are altering the face of the planet.
- Which factors are greatly threatening animal populations.
- How deforestation is contributing to the extinction of certain species.
- What "co-extinction" is, and how climate change may be the dominant driver.

| 0:00.0 | lots of different predictions that allow us to sort of see what would be the extinction rate just |
| 0:05.2 | from climate change with varying degrees of heating. But that has ignored exactly what you just |
| 0:11.1 | said. That has ignored that interaction among species. Species are parts of communities. They |
| 0:17.0 | interact with each other. Sometimes with thousands of other species over their lifespan. And you |
| 0:22.8 | mentioned predators and prey. That's an obvious one. You know, if a predator is a specialist predator, |
| 0:28.0 | it kind of only eats a few different species. If those prey species go extinct and they go |
| 0:33.2 | extinct quickly, then it doesn't have the evolutionary timeframe to adapt to a new diet basically. |
| 0:39.5 | And then therefore it runs out of food. And so it dies as well. But you can also think of pollinators. |
| 0:44.7 | I think you mentioned pollinators and plants. If many, many pollinators are plant specific. |
| 0:50.5 | Forget frequently asked questions. Common sense. Common knowledge. |
| 0:54.9 | How about advice from a real genius? 95% of people in any profession are good enough to be |
| 1:00.3 | qualified in license. Five percent. Go above and beyond. They become very good at what they do. |
| 1:04.9 | But only 0.1% are real geniuses. Richard Jacobs has made it his life's mission to find them |
| 1:11.9 | for you. He hunts down and interviews geniuses in every field. Sleep science, cancer, stem cells, |
| 1:17.2 | ketogenic diets and more. Here come the geniuses. This is the Finding Genius Podcast. |
| 1:23.0 | The Richard Jacobs. Hello, this is Richard Jacobs with the Finding Genius Podcast. |
| 1:31.1 | Now part of the Finding Genius Foundation. Professor Cory Bradshaw. He's the Matthew Flinders |
| 1:36.5 | Professor of Global Ecology, part of the College of Science and Engineering at Flinders University. |
| 1:42.8 | And we're going to talk about his modeling of species extinction. So Cory, thank you for coming. |
| 1:48.8 | Thanks for having me on the show. Yeah, it's kind of an unusual topic. What's your background |
| 1:52.7 | and how did you gain an interest in looking at the future extinction of species? |
| 1:57.5 | Well, I guess it sort of culminates into quite a bit of my career putting together |
