Building on @Amartinez idea, how about trying to establish a few different biology related hashtags right from the start.
I think #Biolodon sounds much better, but since #Biodon is shorter, it might be more convenient.

Please add any that are already established here!

How about this:
Biology - #Biolodon​
Ecology - #Ecolodon​
Evolutionary biology - #Evolodon​
Developmental biology - #Devolodon​
Behavior - #Etholodon (not sure about this one)

Any other ideas?
