However, a recent study recorded a population of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    in the Piquiri River basin (upper Paran\u00e1), although data on its geographic distribution and parasitological aspects are still limited. The study characterized the parasitic fauna of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    in two streams, one from each basin, and compared them in terms of richness, diversity, and parasite community structure. Twenty-six females were collected in a stream in the lower Igua\u00e7u River basin, and 25 females in a stream in the Piquiri River basin (upper Paran\u00e1) in September 2018. The parasite community structure of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    differed between areas, with a predominance of monopisthocotyls and greater richness of parasitic taxa for hosts in the lower Igua\u00e7u River basin. In the Piquiri River basin (upper Paran\u00e1), the parasite community was characterized by a higher prevalence of larval nematodes and a lower richness of parasite taxa. The differences in the richness and structure of the parasite communities between the two areas support the hypothesis of the introduction of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    into the Piquiri River basin (upper Paran\u00e1). Therefore, we emphasize the need for further studies addressing the distribution pattern of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    , as well as additional parasitological studies to determine whether the parasitological taxa of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    are shared in other hydrological systems. This study contributes to the knowledge of the biological aspects of\n                    <jats:italic>P. bifasciatus<\/jats:italic>\n                    in both basins and improves our understanding of how host-parasite interactions can be informative in species introduction scenarios.\n                  <\/jats:p>","DOI":"10.1017\/s0022149x26101199","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T06:11:23Z","timestamp":1774851083000},"source":"Crossref","is-referenced-by-count":0,"title":["Parasites of two populations of\n                    <i>Psalidodon bifasciatus<\/i>\n                    (Characiformes): Enemy release suggesting introduction of hosts in Neotropical streams"],"prefix":"10.1017","volume":"100","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2370-7549","authenticated-orcid":false,"given":"B.S.","family":"Miguel","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"},{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Franceschini","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"},{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.C.","family":"Zago","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.L.","family":"Delariva","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05ne20t07","id-type":"ROR","asserted-by":"publisher"}],"name":"Western Paran\u00e1 State University \u2013 Unioeste"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.A.","family":"Balbuena","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/043nxc105","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Valencia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.P.","family":"Ramos","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"},{"id":[{"id":"https:\/\/ror.org\/00987cb86","id-type":"ROR","asserted-by":"publisher"}],"name":"S\u00e3o Paulo State University (UNESP)"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,3,30]]},"reference":[{"key":"S0022149X26101199_r19","doi-asserted-by":"publisher","DOI":"10.1016\/S2542-5196(23)00275-9"},{"key":"S0022149X26101199_r81","doi-asserted-by":"publisher","DOI":"10.3389\/fevo.2023.1137985"},{"key":"S0022149X26101199_r30","doi-asserted-by":"publisher","DOI":"10.1590\/1676-0611-bn-2018-0666"},{"key":"S0022149X26101199_r55","doi-asserted-by":"publisher","DOI":"10.1590\/1982-0224-20170129"},{"key":"S0022149X26101199_r1","doi-asserted-by":"publisher","DOI":"10.1641\/B580507"},{"key":"S0022149X26101199_r49","doi-asserted-by":"publisher","DOI":"10.1089\/zeb.2017.1551"},{"key":"S0022149X26101199_r80","unstructured":"World Register of Marine Species (2026) WoRMS.
