The Orchid that Pretends It's A Wasp
S1 E3 - 3m 38s
The Hammer Orchid does not look like a flower and has no nectar but also needs to attract a pollinator. This plant's strategy is to synchronize with the mating season of the thynnid wasp, attracting males by emitting a similar scent to that of the female. And since the orchid looks similar to the female, the male it attempts to mate with it.
The Fungi that Help Trees Talk
S1 E3 - 2m 57s
Fungi is able to link a whole group of trees through their root systems, creating a 'wood wide web' called the Mycorrhizal Network. Using this network, trees are able to pass nutrients, chemical and electrical signals to each other raising the alarm when being attacked.
