Summary:

- Trees can communicate with each other through an underground network of fungi and roots, known as the "wood wide web." This allows them to share resources and information.

- Before a solar eclipse, trees were observed to synchronize their communication signals, likely in response to the sudden change in light levels during the eclipse.

- This synchronized communication may help trees prepare for the temporary loss of sunlight and coordinate their responses to the eclipse, such as adjusting their photosynthesis or closing their stomata to conserve water.
