The map shows the Shannon-Wiener diversity index (H`) for benthic epifauna. The Shannon index is a popular diversity index in ecology taking into account the number of species as well as the evenness of species (how close in numbers each species in an environment are). The index is higher with increasing number of species and with decreasing dominance of only few species.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "mapName": "Layers", "description": "", "copyrightText": "Senckengberg am Meer", "supportsDynamicLayers": true, "layers": [ { "id": 0, "name": "Shannon_Index_SaM", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPoint", "supportsDynamicLegends": true } ], "tables": [], "spatialReference": { "wkid": 4326, "latestWkid": 4326, "xyTolerance": 8.983152841195215E-9, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -400, "falseY": -400, "xyUnits": 1.125899906842624E13, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "singleFusedMapCache": false, "initialExtent": { "xmin": 1.0647726590636264, "ymin": 54.20832758103243, "xmax": 10.33522734093637, "ymax": 57.65683748499401, "spatialReference": { "wkid": 4326, "latestWkid": 4326, "xyTolerance": 8.983152841195215E-9, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -400, "falseY": -400, "xyUnits": 1.125899906842624E13, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "fullExtent": { "xmin": 3.4201666666666597, "ymin": 53.718500000000006, "xmax": 7.800666666666757, "ymax": 55.807666666666705, "spatialReference": { "wkid": 4326, "latestWkid": 4326, "xyTolerance": 8.983152841195215E-9, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -400, "falseY": -400, "xyUnits": 1.125899906842624E13, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "datesInUnknownTimezone": false, "minScale": 0, "maxScale": 0, "units": "esriDecimalDegrees", "supportedImageFormatTypes": "PNG32,PNG24,PNG,JPG,DIB,TIFF,EMF,PS,PDF,GIF,SVG,SVGZ,BMP", "documentInfo": { "Title": "Epibenthic diversity (Shannon-Wiener Index H`)", "Author": "", "Comments": "
