SAFBR - Figure 4.14 - Diatom assemblage changes top vs bottom lake cores

Estimation of diatom assemblage changes over a period of about 200 years (top versus bottom sediment cores).

Figure 4-14 Map showing the magnitude of change in diatom assemblages between bottom (pre-industrial) and top (modern) section of the cores,

estimated by Bray-Curtis (B-C) dissimilarity. Boundaries for the B-C dissimilarity categories are based on distribution quartiles (0-30%, 30-40%, 40-

50% and >50%), where the lowest values (blue dots) represent the lowest degree of change in diatom assemblage composition between top and

bottom sediment core samples in each lake.

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 :-)
