Effects of Omnivory on Trophic Cascades

open access: yes, 2016
Omnivores occupy a broad trophic position and have generally been shown to dampen trophic cascades by feeding at multiple trophic levels simultaneously. However, much previous research has neglected to account for several factors such as density and size

The Relative Importance of Heterotrophic Bacteria to Pelagic Ecosystem Dynamics Varies with Trophic State of Reservoirs

open access: yes, 2008
Previous research in pelagic ecosystems suggests that nutrient sequestration and carbon flow through heterotrophic bacteria is relatively high in oligotrophic systems but decreases as trophic state increases.
