@Sheril @rosemarymosco Hmm. There are other potential questions ...

My lad tried a project on tree frogs in a jungle, which involved amongst other things measuring the pH of the water pools in bromeliads at night (or some such). An easy peasy project to publish about, as there appeared, he thought, to be very little existing literature.

But it turned out that carrying a ladder (and a bunch of other kit) around a jungle at night by the light of a head torch is *hard* ... which is no doubt why nobody had done the work before. An interesting theory meets the hard reality of field work logistics. He switched to a different project.

So, there's still some "easy" research here that nobody has done. 🤣 🐸
