The integrated ecological models have three components:
The models have high taxonomic resolution and are looking at importance of taxonomic approach and size classes. Shifts in plankton size are being examined.
Individual based models can be converted to the population level.
The bioenergetics-based model is driven by biological interactions and physical forcings.
A preliminary version of the model is running and predicts primary productivity and some parameter values.
Steve Brandt has been modeling spatial patterns of planktivore abundances and consumption rates, piscivore growth and recruitment rates using spatially explicit bioenergetics models.
Evaluate effects of nutrient loadings on recruitment of summer-breeding fishes using spatially explicit individual based predation models of low O2 effects. The model considers the gradients in temperature, oxygen and salinity in the water and examines the position of larvae and prey, capture and prey encounter, each day as a function of the physical and biotic factors.
