The collective singing at dusk primarily plays a role of territoriality and demonstration of strength. The birds clearly show their neighbors: "Hey, this is my...
The bright colors of corals primarily come from microscopic organisms living in symbiosis with them: zooxanthellae. These are small algae that reside directly in the...
A red tide is a sudden and massive proliferation of aquatic microalgae, mainly organisms called dinoflagellates. When these algae multiply very quickly, their large quantity...
Marine algae use specific pigments that are adapted to capture underwater light. Indeed, underwater, sunlight penetrates more difficultly, and certain wavelengths like red disappear quickly...
Ozone is a molecule composed of three oxygen atoms, represented by the formula O₃. It primarily forms thanks to the energy provided by the sun's...
In some marine algae, the ability to produce light, or bioluminescence, comes from unicellular organisms called dinoflagellates. These tiny creatures use a very specific chemical...
Fungi play a key role as cleaners in forest ecosystems. By breaking down dead wood, fallen leaves, and various plant debris, they transform these wastes...
Tropical forests have a warm and humid climate all year round. This warm and consistently well-watered environment allows species to grow, bloom, and reproduce at...
Plants produce scents to send a genuine chemical signal to insects and other pollinators like bees, butterflies, or bats. Specifically, these scents act like olfactory...
Trees produce toxins as a natural shield against external threats, such as hungry insects or invasive fungi. These chemical substances, sometimes very potent, allow trees...
