An ecological niche is defined as the envelopp of physico-chemical parameters in which a species lives. The niche concept was popularized by the zoologist G. Evelyn Hutchinson in 1957. Here you can visualize the ecological niches of 374 Metagenome Assembled Genomes (MAGs) built from the Tara Oceans dataset. Select below the SMAG of interest and visualize the effect of climate change (high emission scenario RCP8.5) on its niche by clicking on 'Severe climate change' Colors on the maps allows you to visualize the probability of presence at each location of all oceans of the selected MAG




An ecological niche is defined as the envelopp of physico-chemical parameters in which a species lives. The niche concept was popularized by the zoologist G. Evelyn Hutchinson in 1957. IGOB lets you generate 'theoretical' ecological niches for up to 8 species and lets you visualize the effect of climate change on the displacement of these niches. Select the number of species and their habitat (temperature, nutrients (nitrate and phosphate), dissolved silica, iron, salinity and seasonality of nitrate). Click on 'Compute biogeographies' to visualize suitable living areas of your species. To visualize biogeographies after climate change, click on 'Severe climate change'. Be careful, when you click on 'Compute biogeographies', it launches the computation which can take some time. Take time to choose your parameters before.
