Optical control of fish and zooplankton populations
TL;DR: Data is presented suggesting that marine pelagic food webs are primarily structured top-down by light through its effect on vision in fish, and it is shown that the abundance of zooplanktivorous fish is proportional to the vertical extension of a visual feeding habitat, represented by the inverse of the light absorbance coefficient of the water column.

Food Web Structure and Stability in 20 Streams Across a Wide pH Gradient
TL;DR: This study presents 20 highly resolved, standardized stream food webs along a wide pH gradient to assess the influence of external environmental and internal biotic influences on community structure and stability and found clear differences between allometrically inferred measures of per capita interaction strengths within the food web.

Network ecology: Topological constraints on ecosystem dynamics
Ferenc Jordán,István Scheuring +1 more
TL;DR: In this article, a menu of classical and more recently suggested network indices and their relations to ecosystem dynamics are discussed. But the main question is how to link certain graph properties to understanding and predicting the behaviour of an ecosystem.

Homage to the red queen. I. Coevolution of predators and their victims.
TL;DR: A model to describe the coevolution of a two-species predator-victim ecosystem is developed and it is shown that for many such systems, there is a value of J, J ∗, at which the rate of predator evolution exactly equals the rates of victim evolution.

A mathematical model of coevolving populations
Simon A. Levin,J. Daniel Udovic +1 more
TL;DR: The results of the analysis indicate that coevolution may result in stable coexistence of two populations even when the stability conditions derived from generalized versions of the Lotka-Volterra equations are violated; that coEVolution may also destabilize what appears to be a stable interaction between populations; and that coEvolution may results in stable disruptive selection regimes.
