Listen to part of a lecture in the biology class. Today we'll be talking about ants and their nests. Their nests are often built underground right under the soil. It can get pretty dry down there, especially during dry seasons and ants like the rest of us need properly humidified conditions to survive. If the nest gets too dry, it could cause the ants to dry out themselves and to play different techniques to regulate humidity and keep the moisture of the underground air within tolerable limits. One thing some ants do is transport water into their nests to keep the nests hydrated. They forage for water like they would for food and when they find it, they transport the water back to the nest into the interior of the nest to keep the underground air moist a process that can be quite labor intensive. For instance, some ants search the leaves of plants for little water droplets and gather the drops up into their jaws, into their mandables and carry them back one, drop at a time over and over again until the nest is properly humidified. Other ants, instead of going out and foraging for water, they have a different method. They create water traps outside the entrance to their nest, which enables them to sort of harvest the water. Outside the entrance, they place materials that naturally attract and hold water and these materials soak up moisture. So ants can simply come out and collect the water, sort of harvesting from their water traps. 1 type of ant puts bird feathers around the entrance of its nest. The feathers collect water or do drops overnight and in the morning the ants gathered the water and take it inside the nest

The professor talks about two ways ants regulate humidity in their nests. First, some ants go out to find water. For example, they collect water droplets from leaves and carry them back to the nest in their jaws. This helps keep the nest moist. Second, other ants create water traps near the nest entrance. They use materials like bird feathers, which collect water overnight. In the morning, the ants gather the water and take it inside. These methods help ants survive in dry conditions.

The professor explains two strategies ants use to regulate humidity in their underground nests. First, some ants actively forage for water. For instance, they search for water droplets on leaves, collect them in their mandibles, and carry them back to the nest repeatedly. This labor-intensive process ensures the nest remains properly humidified. Second, other ants use a more passive method by creating water traps near the nest entrance. They place materials like bird feathers outside the nest, which naturally absorb and hold water. Overnight, the feathers collect water droplets, and in the morning, the ants harvest the water and bring it inside. These techniques demonstrate how ants adapt to their environment to maintain the necessary moisture levels for survival. -
