Lessons from fungi on markets and economics | Toby Kiers

TL;DR

This content discusses the connection between market economies and fungi, exploring how fungi form trade partnerships and adapt to inequality for survival.

Transcript

So I stand before you as an evolutionary biologist, a professor of evolutionary biology, which sounds like a rather fancy title, if I may say so myself. And I'm going to talk about two topics that aren't normally talked about together, and that's market economies and fungi. Or is it fun-GUY, or, as we say in Europe now, fun-GEE? There's still no co... Read More

Key Insights

• 💼 Market economies and fungi share similar trade principles and strategies. Fungi exchange essential resources with plants, forming trade partnerships similar to stocks and bonds exchanges.
• 🌱 Plant roots are colonized by mycorrhizal fungi, forming complex underground networks. These networks connect multiple plants, acting as an underground subway system for resource exchange.
• 🌍 Approximately 80% of all plant species are associated with mycorrhizal fungi, highlighting their importance in the global economy of plant nutrition.
• 💡 Mycorrhizal fungi trade strategies are determined by natural selection, with the better trading partner consistently favored. However, this trade relationship can create a dependency of the plant on the fungus and result in inflated prices for resources.
• 🤝 There is no altruism in the plant-fungal trade system, with no evidence of the fungus helping struggling plants unless it benefits the fungus itself.
• 🔬 Using a technology involving fluorescent particles called quantum dots, researchers can now study the unseen trade deals underground and understand the effects of inequality on fungal trade.
• ⚖️ Inequality encourages fungi to trade more, helping them cope with the uncertainty of accessing resources. Fungi also actively transport resources from rich to poor areas, manipulating the value of those resources in the network.
• 💻 Fungi are sophisticated trade calculators, using complex flow patterns within their networks to share and process information for making trade decisions. Comparing fungi with computer algorithms may provide insights into more efficient trading strategies.

Questions & Answers

Q: How are market economies and fungi related?

Market economies and fungi are related in that fungi form complex networks underground that function like a market economy. Just as traders in a market economy exchange goods and services, fungi and plants exchange essential resources to benefit both parties.

Q: What resources do fungi and plants exchange in their trade?

Fungi and plants exchange resources such as sugars, fats, phosphorus, and nitrogen. The fungus receives carbon directly from the plant, while the plant gains access to nutrients collected by the fungal network. This trade allows both organisms to thrive and survive.

Q: How do fungi and plants make trade decisions without cognitive abilities?

Although fungi and plants lack cognition, they have trade strategies programmed into their DNA. These strategies determine their trade decisions based on certain conditions and behaviors. Scientists use terms like "strategy" and "trade" to describe these behaviors, even though they differ from human cognitive decision-making processes.

Q: How do fungi and plants exploit each other in their trade relationship?

Fungi and plants can engage in exploitative behaviors in their trade relationship. Some fungi can suppress the plant's ability to take up nutrients, creating a dependency on the fungus. Additionally, fungi may hoard nutrients, inflating their value, and forcing the plant to pay more for the same resources. Plants, on the other hand, may also exploit fungi, such as certain orchids that tap directly into the fungal network and steal carbon without giving anything in return.

Q: How does inequality affect trade in fungal networks?

Inequality in resource availability encourages fungi to engage in more trade within their networks. Fungi actively transport resources from rich patches to poor patches, manipulating the value of those resources. This suggests that trade partnerships can help organisms cope with uncertain access to resources and that fungi can adapt their trade strategies based on market conditions.

Q: How do fungi sense market conditions and make trade decisions without cognition?

Fungi sense market conditions and make trade decisions by sharing, processing, and integrating information across their network. The complex flow patterns inside the hyphal network allow fungi to communicate and make trade decisions. Scientists are studying these flow patterns and working with biophysicists to understand how fungi use this information to calculate and optimize their trades.

Q: Can computer algorithms compete with fungi in making trade decisions?

Fungi, with their uncognitive trade strategies, may actually outperform computer algorithms in making trade decisions. While computer algorithms rely on mathematical models, fungi have been evolving and adapting their trade strategies for millions of years. Many believe that fungi, as living organisms, are better at making trade calculations and decisions than computer algorithms.

Summary & Key Takeaways

• The speaker discusses the connection between market economies and fungi, highlighting the similarities in trade strategies between plant-fungal partnerships and human trade deals.

• Fungi form underground networks called mycorrhizae, which connect multiple plants simultaneously and facilitate the exchange of essential resources such as carbon, phosphorus, and nitrogen.

• The study of fungal trade can provide insights into the effects of inequality and the ways organisms in nature adapt and trade to cope with uncertainty in resource access.
