|Project:||Self-organisation of community metabolism|
Naturally, the precise type of communities that arise depend on their environment they live in, but equally important is the feedback from the communities on the environment. Together, a community and its environment are called an ecosystem.
The phenomenons of `ecosystem' and `food web' give rise
to many questions:
Evolution: from a single-species community to a complete foodweb
We will try to model this whole process of self organization by combining two existing theories (Dynamic Energy Budget and Adaptive Dynamics). AD is used to quantify adaptation and speciation in organisms, DEB specifies general rules for uptake and use of substrates in organims. A short description of both theories is given below.
Adaptive Dynamics: The theory on Adaptive Dynamics (AD) is about quantitative changes at an evolutionary time scale in characteristics of species, as described by parameter values. These characteristics include rules for the (sloppy) heredity of parameter values in parent-offspring transitions. The theory can predict under what circumstances the scatter distribution of individual-specific parameters values breaks up, a process that corresponds with speciation.
Dynamic Energy Budget: The Dynamic Energy Budget Theory (DEB) is a general framework for modeling organisms, which links different levels of biological organisation (cells, organisms and populations). The theory presents simple mechanistic rules that describe the uptake and use of energy and nutrients (substrates, food, light) and the consequences for physiological organisation throughout an organism's life cycle.
This is the symposium that concludes my project:
