Stochasticity and Space Project
Things we Need:
- Explicit hypotheses
- links to papers,
- state variables
- definitions of agent traits w.r.t. space variables,
- forcing conditions
- sample code?
Looks like we can do anything on a square grid in NetLogo, and even import GIS data.
- Limiting resource (which can also be in excess)(E.g., water, nutrients)
- Patch/cell/region ability to conserve resource (E.g., soil organic matter)
- Patch connections (e.g., elevation -> horizontal flow)
- Connectivity (i.e. how well patches are connected)
- Efficiency in capturing resource
- Efficiency in surviving low-resource conditions
- R-k strategy
- Spatial reach, for getting resource or spreading offspring
- Interactions? One kind of agent more efficient in the presence of another?
- Threshold responses to external inputs, or saturation
- What ecological processes does an agent do? (e.g. growth, water uptake, nutrient uptake, death, dispersal etc.)
- Input of resource, variable in space or time
- Variance of input
- Variable resource input favors different agent traits than reliable inputs with the same mean value
- Agents develop spatial variability to gather sparse resources
- Unreliable resources favor cooperative strategies (Demetrius, e.g.)
- Hubler's hypotheses: with little noise, the system minimizes dissipation and is efficient; with much noise, the system maximizes dissipation and is robust.

maybe we need emails to facilitate communications.

we are looking for the unknown X in Xeriscapes.
