dBdt: Dynamics from EcoSim

In ecostate: State-Space Mass-Balance Model for Marine Ecosystems

Dynamics from EcoSim

Description

Compute system of differential equations representing EcoState dynamics derived from EcoSim.

Usage

dBdt(
  Time,
  State,
  Pars,
  type_i,
  n_species,
  F_type = "integrated",
  what = "dBdt"
)

Arguments

Time	not used
State	vector of state variables to integrate
Pars	list of parameters governing the ODE
type_i	type for each taxon
n_species	number of species
F_type	whether to integrate catches along with biomass ("integrated") or calculate catches from the Baranov catch equation applied to average biomass ("averaged")
what	what output to produce

Details

This function has syntax designed to match pracma solvers.

Value

An object (list) of ranges. Elements include:

G_i

Biomass growth per time

g_i

Biomass growth per time per biomass

M2_i

Consumptive mortality per time

m2_i

Consumptive mortality per time per biomass

M_i

Natural mortality per time

m_i

Natural mortality per time per biomass (i.e., m2_i + m0_i)

Q_ij

Consumption per time for prey (rows) by predator (columns)
