SAFBR - Figure 3.6 - Temperature Change

Figure 3-6. The hypothesized effects of rising mean water temperature on biodiversity (as total species number) of Arctic freshwater ecosystems. A pulsed increase in gamma biodiversity (a) results from the combination of high eurythermal invasion and establishment and low stenothermic loss with increasing water temperature. A pulsed decrease in gamma biodiversity (b) results from the combination of low eurythermal invasion and establishment and high stenothermic loss. Rapid increases (c) and slow increases (d) in species diversity occur, respectively, with high eurythermal invasion and establishment coupled with high stenothermic loss or low eurythermal invasion and establishment and low stenothermic loss as temperatures increase. For simplification, barriers to dispersal have been assumed to be limited in these models.

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 :-)
