We describe experiments done in using the lemon model for encoding lexicographic data we got from different sources with distinct coverages. Our focus is on delivering statements on lessons learned and on questions that still should be discussed in the lemon community, as a possible input for forthcoming versions of the model.
Antarctic anemones of the genus Halcampoides inhabit low intertidal and shallow subtidal zones. They readily burrow into soft sediments following disturbance. The process of re-burying was recorded using time-lapse video in the aquarium of the British Antarctic Survey with specimens of a species collected from the shallow sublittoral (<1 m depth) at Signy Island. Penetration of the sediment tak...
