Floats Subcaption – Spanning Figures Over Multiple Pages in LaTeX

floatssubcaption

I am trying to get subfigures to span multiple pages. I have declared a new floating environment because these are supplmental figures. And I am using the 'subcaption' package so as to have subfigures. However, I cannot figure out how to have the subfigures span more than one page. What happens in my minimal reproducable example below is that all three subfigures of figure 2 end up on the same page. I have tried to add \newpage or \clearpage after the second subfigure, but this doesn't do anything. (You can toggle the \clearpage command on or off if you wish in my example).

Might anyone have any suggestions as to how these figures can span multiple pages?

Thank you.

Area values are the average of the number of replicates for which a community and thus the respective species were replicated in the chemostat.}

Blue points indicate that the focal species in the row view interacted with and was present with the competitor species in the column view. Shaded subplots represent a significant species interaction. Blue shade indicates the evolved growth rate of the focal species was significantly higher in the presence, when compared to the absence, of the competitors species; red shade indicates the evolved growth rate of the focal species was significantly lower in the in the presence of the competitor species. The horizontal dashed line indicates the evolved growth rate of the focal species ancestor.}

Try using two suppfigure environments for the last three images, using your own.
