Aquatic-terrestrial subsidies
Aquatic-terrestrial subsidies are a type of ecological resource subsidy in which materials, energy, and nutrients are transferred from aquatic to terrestrial ecosystems. Aquatic-terrestrial subsidies are typically caused by organism movement across the aquatic-terrestrial boundary. For example, emerging aquatic insects develop in streams and lakes before emerging as winged terrestrial adults.[1] After emerging, many adult aquatic insects are eaten by terrestrial animals like spiders, birds, bats, and lizards.[2] Because the adult aquatic insects are produced in a different ecosystem than their predators (aquatic versus terrestrial), movement of aquatic insects to terrestrial food webs is termed a subsidy.
