Bradley Allf is a PhD student at North Carolina State University in the USA. He kindly agreed to share with us a project he did for a programming class that you might be interested in.

For this project, he created a food web of all the observations of animal predation or herbivory recorded in the project Interactions (s Afr).
You can see the food web, and a general outline of his process, in the link below.

Bradley says:
"This project was really neat and allowed me to get a sense for what kinds of observations on animal feeding people were making in Southern Africa and recording for your project. This project actually inspired me to start my own iNaturalist project to record animal feeding observations all over the world to (someday) create a sort of hub of feeding ecology and global food web. You can find that project here (https://www.inaturalist.org/projects/who-eats-who). "

A nice example, how, just by recording interactions, one can contribute to great science!
