Cómo Sobreviven los Árboles en Invierno

Trees originally evolved in tropical climates and are not naturally equipped for sub-zero temperatures. Cold weather poses challenges like ice formation and air bubbles in tree pipes, which can disrupt water flow. To survive, trees have developed adaptations such as narrower pipes to prevent bubble blockages and techniques like using sugary sap as antifreeze. These adaptations also help in drought conditions. Some trees, like conifers, use sugary sap to keep leaves thawed, while others shed leaves to avoid frost damage. These strategies have allowed trees to thrive in both cold and dry tropical climates.
