“…For S. jurupari, there was an absence of the body size correlation with the ecological and community descriptors, as well as with the parasite abundance. This may be an indication that the length and body mass of this host, do not in fact exert an influence over the variation of the parasite infracommunities, as also reported for other hosts (Poulin and Fitzgerald 1987;Alcântara and Tavares-Dias 2015).…”

“…Changes in parasite abundance with monoxenic life cycle have been generally considered to be influenced by both the environment and biotic factors (Poulin and Fitzgerald 1987;Rohde et al 1995;Marcogliese et al 2006;ViolanteGonzález et al 2009;Rohlenová et al 2011;Tavares-Dias et al 2014, Alcântara and. For example, monogeneans and protozoans are good indicators of water quality, because they typically infest fish gills and skin, and are exposed to the environment throughout their monoxenic life cycle Chapman et al 2015;Alcântara and Tavares-Dias 2015). Our results indicate that the species composition and species richness of ectoparasites were higher than those for endoparasites.…”

Assessment of biodiversity is fundamental for the understanding of ecological interactions, but fish parasites were neglected in biodiversity estimates for a long time. The aim of this paper was to investigate the diversity of parasites in Satanoperca jurupari in the Amazon River system in Brazil. Of the fish examined, 90.0% were parasitized by one or more species of protozoans and metazoans, and a total of 3,110,094 parasites were collected. Ichthyophthirius multifiliis, Piscinoodinium pillulare, Sciadicleithum juruparii, Clinostomum marginatum, Posthodiplostomum sp., Genarchella genarchella, Argulus multicolor and Ergasilus coatiarus were found. However, I. multifiliis and P. pillulare were the most prevalent, abundant and dominant parasites, while A. multicolor and G. genarchella were the least prevalent and abundant parasites. The parasites had an aggregate dispersion, but E. coatiarus and the endoparasite species had a higher aggregation pattern. The species richness of parasites varied from 1 to 8 species per host, the Brillouin index varied from 0.32 to 1.09 and evenness varied from 0.01 to 0.47. The host size did not influence the diversity indices and the abundance of parasites, which did not affect the body condition of the hosts. Satanoperca jurupari is a new host for G. genarchella.

“…Parasites are typically found in communities in which different species coexist in fish of the same host species or in different host species (MUÑOZ et al, 2006;TAVARES & LUQUE, 2008;BELLAY et al, 2013;ALCÂNTARA & TAVARES-DIAS, 2015). Protozoan and monogenoidean ectoparasites are parasites typical of lentic environments, but their reproduction is strongly favored by eutrophized environments like the hydrographic basin of this study (TAKIYAMA et al, 2012).…”

“…Parasitism has been implicated as an important factor in the population dynamics of fish species (POULIN & FITZGERALD, 1987;ALCÂNTARA & TAVARES-DIAS, 2015;PANTOJA et al, 2016). The parasites can be found in host communities and coexists in the same individual of a single host fish species, or in different host fish species (MUÑOZ et al, 2006;TAVARES & LUQUE, 2008;ALARCOS & TIMI, 2012).…”

This study investigated the parasite communities of wild Acestrorhynchus falcatus and Acestrorhynchus falcirostris populations living in sympatry in Brazilian Amazon. In these two hosts, a total of 12 parasite species e 1-9 parasite species were found per fish, and 10 of these species are metazoans. Eight species of parasites were common to both host species and four of them exhibited differences in abundance and/or prevalence. Parasite communities of the hosts were taxonomically similar (83%) and composed of both ectoparasites and endoparasites, and characterized by high prevalence and high abundance of endoparasites and an aggregated dispersion pattern. For A. falcirostris, the dominant parasite was Ichthyophthirius multifiliis, and for A. falcatus, it was Piscinoodinium pillulare. Shannon diversity and Berger-Parker dominance were similar for both hosts, while the parasites species richness and evenness showed differences influenced by the ectoparasites species. These two populations of hosts that inhabited the same geographical area had different sizes, but were exposed to the same infective stages, and acquired qualitatively and quantitatively similar endoparasites community, thus indicating that the amounts and types of prey congeneric that they were eating were similar. Therefore, the overlap in the same occurrence area play an important role in the parasite communities to these phylogenetically related hosts.

“…They are piscivorous fish when adults, but juveniles also feed on plankton, crustaceans, insects and seeds. These species are habitually active at twilight and night and do not undertake migration (Santos et al 2006;Soares et al 2011;Alcântara and Tavares-Dias 2015). They are also commonly found in the Amazon River system, which is a complex ecosystem that in-cludes tributary rivers and streams, with floodplains and periodically flooded forest alongside them.…”

The present study investigated the effects of seasonal variation in parasites infracommunities of Hoplerythrinus unitaeniatus and Hoplias malabaricus from a tributary of Amazon River. For H. unitaeniatus and H. malabaricus, 11 parasite species were similar, and greatest parasite richness occurred during the rainy season. Ichthyophthirius multifiliis was the dominant parasite species for both hosts. In H. unitaeniatus, infection by Whittingtonocotyle caetei, Whittingtonocotyle jeju, Urocleidoides sp. and Anacanthorus sp. was higher during rainy season. Contracaecum sp., Procamallanus (Spirocamallanus) inopinatus, Nomimoscolex matogrossensis and Gorytocephalus spectabilis showed no seasonal pattern. For H. unitaeniatus, P. pillulare, Clinostomum marginatum and Argulus pestifer occurred only during dry season, while Trichodina sp., Dolops geayi, undetermined metacercariae and Posthodiplostomum sp. occurred only during the rainy season. In H. malabaricus, the prevalence of Urocleidoides eremitus was similar during the two seasons, but abundance was higher during the rainy season. Tetrahymena sp., C. marginatum, Dendrorchis neivai, undetermined metacercariae, Posthodiplostomum sp., Genarchella genarchella, Cystidicoloides sp., G. spectabilis, D. geayi, A. pestifer and Glossiphonidae gen. sp. occurred only during the dry season. However, Contracaecum sp. and P. (S.) inopinatus occurred during both seasons, but the prevalence of P. (S.) inopinatus was higher during the rainy season. Seasonal variation in this infection levels was due to the host's feeding behavior and habits and the availability of infectious forms of parasites with heteroxenic life cycles. The non-seasonal fluctuation detected are likely a result of the parasites biology, highly variable nature of this tributary of Amazon River and low abundance of parasites.
