| Abstract: |
| The Numerical Ecology unit studies marine plankton using digital imaging techniques combined with automated and semi-automated machine learning classification. The research focus is on the adaptation potential of these animals to environmental changes (temperature, acidification and eutrophication). Furthermore, the research group also develops scientific software, which is called Zoo/PhytoImage, for the elaboration of spatio-temporal plankton series by automating the sample processing. This open-source software allows to analyse various kinds of digital images of plankton, and to measure, count and classify the different planktonic organisms digitally fixed on these images. It then calculates ecologically important variables, such as abundances, biomasses and size spectra by taxonomic group or for the whole sample. Also other extensions to R software are developed, such as SciViews for a homogenisation of its user interface, pastecs for the analysis of spatio-temporal series in ecology, aurelhy for the spatial interpolation of hydro-climatic variables, or the generation of graphs to be directly used for publication. |
