Abstract

The circulation of energy is not confined to a single ecosystem but there is a reciprocal subsidy transfer between adjacent habitats. Peak productivities in adjacent ecosystems can alternate thus changing the direction of energy flow. The most of its energy in an oligotrofic lotic system provides from outside (allochtonus) sources. Mostly in form of leaf-litter. Aquatic insects use leaf-litter as food and habitat. Emerging insects provide food sources for riparian predators. This is the way that energy once entered the stream comes back to the land in a time of low terrestrial prey biomass. The abundance of insects and their diversity is affected by the quality of fallen leaves. It is important to understand the connection between terrestrial and aquatic acosystems in order to effectively implement their protection.
