Warned trees immediately flood their leaves with toxic tannins to deter the pests.
The secret language of cells
Whispering woods and talking trees
The animal chatterbox
Microbe meetings and fungal internets
sonia Mycorrhizal fungi connect plant roots, letting trees transport carbon, water, and nitrogen while transmitting chemical distress signals during pest attacks.
What primary resource do mature trees often share with shaded saplings through fungal networks?
What toxic chemical do acacia trees produce in their leaves to deter feeding giraffes?
Acacia defense: When acacia trees warn each other of giraffes, the giraffes learned to walk upwind to feed on unwarned trees.
sonia Match chemical SOS signals to learn how plants summon insect bodyguards for defense.
What is the term for airborne chemical signals released by plants to communicate with other species?
The branch of biosemiotics that studies sign processes, communication, and meaning-making in plants. Semiotician Martin Krampen introduced this field in 1981 to explain how plants interpret environmental signs.
sonia The Bright Signs of Flowers
We only see the yellow, but the bees can see the glow, The bright signs of flowers guide them where the sweet nectars flow.
