Density

Functions to estimate density under fishing

density_perturb() density_metier() density_logistic(): Estimates density at specific times for the logistic and perturbation model. density_metier allows to specify different metiers.

Steady-state

Functions to estimate steady-state under fishing

steady_perturb() steady_metier() steady_logistic(): Estimate steady-state density for logistic and perturbation model for one and more metiers.

Trawl

Functions to estimate density at trawling events

trawl_perturb() trawl_metier(): Estimates density before and after a trawling event, or the average density between trawls.

Models as in deSolve

Functions to estimate density using deSolve input

run_perturb() run_logistic(): Functions to estimate the impact of bottom disturbances on benthic taxa. Allows for non-regularly spaced events.

Model parameters

Functions to estimate the model parameters

par_r() par_d() par_K() par_m(): Estimate model parameters for use in the fishing impact model.

Ecosystem functions

Functions to estimate ecosystem functions or traits

get_Db_model() get_irr_model() get_sptrait_model(): From model output (time x taxon density) to time x species_bioturbation or time x species_bioirrigation potentials. get_sptrait_model extracts the contribution of a species to an arbitrary trait

get_trait_model(): Function to obtain (time x trait) data by combining model output (time x taxon) with trait (taxon x trait) data.

Sensitivity functions

Sensitivity of an area or taxon to fishing parameters

sensitivity_taxon() sensitivity_area(): Sensitivity of an area or taxon to fishing parameters

Critical values

Critical values for fishing or taxon parameters

critical_sar() critical_gpd() critical_r() critical_d(): Critical values for fishing or taxon parameters.

Data sets
