Cumulative numbers of marine fish diversity (n = 633, Appendix 6.2) in the Arctic Ocean and adjacent seas (AOAS) from 1758 to the present. Species are broadly grouped according to zoogeographic pattern (cf. Section 6.3.1): Arctic (A, blue symbols) and non-Arctic (Σ AB, B, WD, red symbols). Grey bars denote periods with many descriptions of new Arctic species. Note that 75% of the non-Arctic species known to science were described by 1912, whereas the same proportion for Arctic species was only reached in 1976. See text for further information.

Vegetation indices quantify the concentrations of green leaf vegetation (chlorophyll)around the globe, in an attempt to monitor and correlate vegetation health and stress. The MODIS vegetation products include the Normalized Difference Vegetation Index (NDVI)and an Enhanced Vegetation Index (EVI). Included in the MOD13C1 product is both NDVIand EVI, so both have been provided for the CAFF Dedicated Pan-Arctic Satellite RemoteSensing Products and Distribution System. These indices come in a variety of resolutions,but MTRI has provided a monthly global composite on a 0.05° Climate Model GRID(CMG).

The number of species depends partly on what has been studied. Proportions vary somewhat around the Arctic, but diatoms and dinoflagellates are the most diverse groups everywhere. The greatest sampling effort has been in the Laptev Sea, Hudson Bay, and the Norwegian sector of the Barents Sea. Species shown are among the most commonly recorded.

Map of the Arctic Ocean showing the distribution of species richness of Bryozoa for different shelf seas along the Eurasian continental shelf. Diameters of circles are proportional to the number of bryozoan species given in Tab. 8.3. Species numbers partitioned into six zoogeographical affinities are shown from the: Barents Sea (Denisenko 1990), Kara Sea (Gontar & Denisenko 1989); Laptev Sea (Gontar 2004), East Siberian Sea (Denisenko 2010), Chukchi Sea (Denisenko 2008).

The MODIS Land Cover Type product is created yearly using three landclassification schemes; the International Geosphere Biosphere Programme (IGBP)classification scheme, the Univertiy of Maryland (UMD) classification scheme, and aMODIS-derived Leaf Area Index /Fraction of Photosynthetically Active Radiation(LAI/fPAR) classification scheme (Table 3). The International Geosphere Biosphere Programme (IGBP) identifies seventeenland cover classes, including eleven natural vegetation classes, three non-vegetated landclasses, and three developed land classes. The product provided is derived using the samealgorithm as the 500 m Land Cover Type (MOD12Q1), but is on a 0.05° Climate Model Grid(CMG), that has been clipped to the pan-Arctic extent. The UMD classification scheme issimilar to the IGBP classification scheme, but it excludes the Permanent wetlands,Cropland/Natural vegetation mosaic, and the Snow and ice classes. The LAI/fPARclassification scheme is the smallest of the three, and focuses on forest structure; it only haseleven classes. All three land cover classification schemes are provided, but the IGBPclassification scheme is the most amenable to the Pan-Arctic region.

Based on published scientific literature, the diversity of plants in the Arctic is reviewed. The plants are divided into three main groups according to essential differences in anatomy, morphology and reproduction. These are vascular plants, bryophytes (mosses and liverworts) and algae (micro- and macroalgae). As a whole, these three plant groups have the ability to perform photosynthesis. As primary producers they play a key role in the environment, since photosynthesis provides resources for all other organisms. Vascular plants and bryophytes (together with the lichenized fungi, the lichens) are the main structural components of terrestrial vegetation and ecosystems, while algae are more abundant in fresh water and marine ecosystems.
