3. Aquatic Ecosystem Maintenance
Capybaras significantly contribute to the health of aquatic ecosystems through their daily activities and behaviors. As semi-aquatic mammals, they spend much of their time in and around water bodies, creating essential connections between terrestrial and aquatic habitats. Their movement patterns help maintain the structure of riverbanks and shorelines, preventing excessive erosion and forming small channels that improve water flow and distribution. Capybaras act as ecosystem engineers by entering and exiting water bodies, creating gentle slopes and access points that other species can use. Their presence in aquatic environments also helps control the growth of aquatic vegetation, preventing the overcrowding of water plants that could otherwise lead to reduced oxygen levels. Their swimming activities help circulate water in smaller pools and lagoons, which is essential for maintaining proper oxygen levels and preventing stagnation. Studies of water bodies frequented by capybaras have shown that their actions create diverse microhabitats and maintain higher water quality, supporting a greater variety of aquatic life. Their movement patterns disturb sediment and provide temporary shelters for aquatic invertebrates, offering opportunities for small organisms to thrive in aquatic environments.
