Numerical and functional responses are considered for analysis, and the fundamental and realized spatial niches (FSNs and RSNs) are measured as part of the study. While it was not possible to measure the FSN of<jats:italic>Aggregata<\/jats:italic>sp., the analysis of the infection levels of<jats:italic>O. superba<\/jats:italic>recorded for non-concomitantly and concomitantly infected hosts suggests that the gills and body skin constitute, respectively, the main and accessory sites of infection of the parasite. According to the evidence found, the gills function mainly as an accessory site of infection of<jats:italic>Aggregata<\/jats:italic>sp., in specimens in which the caecum and intestine are massively infected. Evidence for a negative interaction between<jats:italic>Aggregata<\/jats:italic>sp. and<jats:italic>O. superba<\/jats:italic>has been found while controlling for a potential confounding effect of host size. Furthermore, the presence of<jats:italic>O. superba<\/jats:italic>on gill lamellae appears to have been negatively affected by the presence of<jats:italic>Aggregata<\/jats:italic>sp., while this latter remained mostly undisturbed. The mean number of oocysts of<jats:italic>Aggregata<\/jats:italic>sp. in the gills was higher in spring and summer, which were also the seasons presenting the broadest RSN for<jats:italic>O. superba<\/jats:italic>.<\/jats:p>","DOI":"10.1017\/s0031182013001406","type":"journal-article","created":{"date-parts":[[2013,10,22]],"date-time":"2013-10-22T12:49:40Z","timestamp":1382446180000},"page":"216-226","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Numerical and functional responses to the presence of a competitor \u2013 the case of<i>Aggregata<\/i>sp.
