Thanks so much Peter! I had come across this one but sadly, it only deals with the Neotropics. I don't have the confidence to extrapolate to India and to Piper nigrum. All this for a kids' book. I hope they appreciate the effort that goes into accuracy! Thank you again. Jon

Thanks again! Not sure I totally trust this source. I can't find anything in the scientific literature. I've sorted to a couple of botanic gardens in India. Will post here if I get a response. Thanks, Jon

Thanks Peter! Yes, wondering about specific animals that might disperse the seeds in India.

Thank you. Yes I wanted to know if there's a particular kind of animal that's mostly responsible. Eg. Bats or birds? The wee fruits turn red, so I was thinking birds, but if love to know for sure.
