Nature has some great articles about dragons, that I came across lately. They are old, and probably well known. But I wanted to list them here anyway.
The first one by Hamilton, May and Waters is a warning that with climate change, the conditions for dragon breeding are rapidly reaching ideal conditions. And they are warning that the „Third Stir“ might take place soon.
The second article I came across is on the ecology of dragons by May. It is about the ecology and origin of dragons and why they might have gone extinct.
