The influence of predator--prey population dynamics on the long-term evolution of food web structure.
We develop a set of equations to describe the population dynamics of many interacting species in food webs. Predator-prey interactions are nonlinear, and are based on ratio-dependent functionalExpand

Interactive effects of body-size structure and adaptive foraging on food-web stability.
Body-size structure of food webs and adaptive foraging of consumers are two of the dominant concepts of our understanding how natural ecosystems maintain their stability and diversity. The interplayExpand

Biological evolution and statistical physics
This review is an introduction to theoretical models and mathematical calculations for biological evolution, aimed at physicists. The methods in the field are naturally very similar to those used inExpand

The impact of nonlinear functional responses on the long-term evolution of food web structure.
We investigate the long-term web structure emerging in evolutionary food web models when different types of functional responses are used. We find that large and complex webs with several trophicExpand

Random Boolean Networks
This review explains in a self-contained way the properties of random Boolean networks and their attractors, with a special focus on critical networks. Using small example networks, analyticalExpand

We present a model for the maintenance of sexual reproduction based on the availability of resources, which is the strongest factor determining the growth of populations. The model comparesExpand

Emergence of complexity in evolving niche-model food webs.
We have analysed mechanisms that promote the emergence of complex structures in evolving model food webs. The niche model is used to determine predator-prey relationships. Complexity is measured byExpand

Number and length of attractors in a critical Kauffman model with connectivity one.
The Kauffman model describes a system of randomly connected nodes with dynamics based on Boolean update functions. Though it is a simple model, it exhibits very complex behavior for "critical"Expand

When do evolutionary food web models generate complex networks?
Evolutionary foodweb models are used to build food webs by the repeated addition of new species. Population dynamics leads to the extinction or establishment of a newly added species, and possibly toExpand
