An Invasive Species Reduces Aquatic Insect Flux to Terrestrial Food
... Aquatic food webs are often subsidized by allocthonous plant and animal material from terrestrial food webs (e.g. Nakano et al. 1999). These subsidies provide essential nutrients and energy; especially in systems where autochonous primary productivity is low, such as heavily shaded headwater streams ...

Omnivore Population Dynamics and Trophic Behavior
... The trophic level concept is commonly used to position organisms hierarchically in a food chain (Lindeman, 1942). An organism’s trophic position represents its sequential order from the base of the chain. Primary producers (plants) occupy trophic position one, primary consumers (herbivores) occupy p ...
