Table 4 Co-occurrence analysis considering healthy ibexes and two stages of S. scabiei infestation/mange severity (mildly and severely infested hosts). The significance between observed (O) and expected by chance (E) values of the C-score, number of checkerboards and number of species combinations is presented for presence/absence matrices of ectoparasite communities of 214 Iberian ibexes

From: Sarcoptes scabiei infestation does not alter the stability of ectoparasite communities
