-This is an R Markdown document. Markdown is a simple formatting syntax for authoring web pages (click the **MD** toolbar button for help on Markdown).
 
-When you click the **Knit HTML** button a web page will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
+Problem of structural uncertainty in managing ecological systems.  Motivate via the widepread concern of tipping points, more general concerns of complex/nonlinear dynamics.

-You can also embed plots, for example:

-```{r fig.width=7, fig.height=6}
-plot(cars)
