species.info

Additional species information required to calculate several indicators (see
vignette).

datasets

Provides functions to calculate indicators for four marine ecosystem attributes (Biodiversity, Ecosystem Structure and Functioning, Ecosystem Stability and Resistance to Perturbations, Resource Potential) and one marine ecosystem pressure (Fishing Pressure) from fishery independent trawl survey data and commercial landings data. All indicators were selected and evaluated using the <e2><80><9c>Indicator Selection Guidance Framework<e2><80><9d> developed by Bundy, Gomez, and Cook (2017, ISBN: 978-0-660-23573-8).
