Preliminary test: Mikel Etxeberria and the balance of the ecosystem

We made an appointment in his office of the Aranzadi Science Association with the Beasain Mikel Etxeberria Okariz. He is a biologist and has to do his pre-computer work, although his natural habitat is the mountain. One of the natural science departments of the Summer Basque University, he launched the website Euskalnatura.eus a few years ago, an outreach project aimed at young nature lovers. Will he pass the preliminary test?
