Welcome

The working group of Prof. Dr. Christian Möllmann is analysing climatic and fishery induced effects on the structure and functioning of marine ecosystems with the goal to develop better ecosystem-based management strategies.

INDperform

Saskia Otto and a team of Master and PhD students just released a software tool - the R package ‚INDperform‘ - that helps validating the performance of ecological indicators and assessing the ecosystem status based on a suite of indicators. The package is build on a framework recently published by Saskia and co-authors (Otto et al. 2018) and offers functions to

  • identify temporal indicator changes,
  • model relationships to pressures while taking non-linear responses and temporal autocorrelation into account, and to
  • quantify the robustness of these models.

It can be installed from CRAN directly or from github as development version: https://github.com/saskiaotto/INDperform.
