The Ya'axché Conservation Trust has a cool short out about biodiversity when it comes to cohunes and gibnut. Some of the film is in Mayan, with English subtitles. Definitely worth a watch.
"The cohune, the gibnut and us is a short film produced by Ya'axché Conservation Trust in Belize, Central America. The film is explains the concept of biodiversity and what an ecosystem is, and why we humans need to take care not to break the links in the forest ecosystem. The film uses the example of the gibnut (paca), a ground dwelling rodent which disperses the nuts of the cohune palm, which is used for thatching. The paca is also hunted for meat by humans.
