“…Several authors have suggested the pivotal role of this species as shaper of vegetation dynamics, acting as a keystone species in these insular ecosystems during the Pleistocene and Holocene (Palmer et al, 1999;Winkler et al, 2013b;Welker et al, 2014). Although no seeds have been found so far in any coprolites (Rivera et al, 2014;Welker et al, 2014), it is not discarded that M. balearicus could also feed on fruits (as many goats do today, e.g., Mancilla-Leytón et al, 2015;Delibes et al, 2017a) and discard seeds intact, thus acting also as a legitimate disperser. On the other hand, even though the origin of C. humilis in the Balearic Islands remains uncertain (Carrión, 2012), its old presence in the eastern coast of the Iberian Peninsula (Arroyo et al, 2004;Pérez-Obiol et al, 2010) would make more plausible the hypothesis of a Balearic existence before the recent human arrival.…”
