SAFBR - Figure 4.7 - Diatom lake diversity

Figure 4-7 Circumpolar assessment of lake diatoms, indicating (a) the location of lake diatom stations, underlain by circumpolar ecoregions; (b) ecoregions with many lake diatom stations, colored on the basis of alpha diversity rarefied to 40 stations; (c) all ecoregions with lake diatom stations, colored on the basis of alpha diversity rarefied to 10 stations; (d) ecoregions with at least two stations in a hydrobasin, colored on the basis of the dominant component of beta diversity (i.e. species turnover, nestedness, approximately equal contribution, or no diversity) when averaged across hydrobasins in each ecoregio.

Supplemental Information: You can customize the template to suit your needs. You can add

and remove fields and fill out default information (e.g. contact details).

Fields you can not change in the default view may be accessible in the more

comprehensive (and more complex) advanced view. You can even use the XML editor

to create custom structures, but they have to be validated by the system, so

know what you do :-)
