“…Our results shed light on the formation and development of the tropical communities of helminth parasites of freshwater fishes, and give additional support to the idea that the distribution of the species of helminths follows that of their host families [29–31]. When a colonizing fish arrives in a new habitat, it brings its parasites.…”

“…This pattern has been documented in northern temperate fishes [5, 7, 35] as well as in tropical Mexican freshwater fishes [2, 6, 22, 28–31, 37]. As a result, host specificity appears to be an important factor in the distribution of parasites, since the distribution of helminths reflects that of the fish families they parasitize [3, 29–31]. This concept is widely accepted; however, few if any investigations have been conducted in order to test this tenet in a given host assemblage.…”

“…Each fish family commonly seems to have a set of parasites that are exclusive to and widely distributed in the host family, with limited host-sharing among them. This pattern has been documented in northern temperate fishes [5, 7, 35] as well as in tropical Mexican freshwater fishes [2, 6, 22, 28–31, 37]. As a result, host specificity appears to be an important factor in the distribution of parasites, since the distribution of helminths reflects that of the fish families they parasitize [3, 29–31].…”

“…they behave mostly as specialists) [17]. Acanthocephalans in Mexican and Central American freshwater fishes are seldom, if ever, common [29–31], such that their absence is a crucial distinction between temperate and Neotropical fish helminth communities (Kennedy CR Pers. Com.).…”

Host specificity and the structure of helminth parasite communities of fishes in a Neotropical river in Mexico

et al. 2016

In a tropical locality of Río La Antigua, Veracruz, Mexico, 11 fish species, represented by 244 individual fish from six freshwater fish families living sympatrically and synchronically, were examined for helminth parasites. A total of 36 taxa of helminths were recorded, 24 autogenic and 12 allogenic forms, including 6 monogeneans, 14 trematodes, 1 cestode, and 15 nematodes. Most helminth taxa were recovered for 10/11 of the component communities we analyzed. The results contribute empirical evidence that host specificity is an important force in the development of helminth communities of freshwater fishes. Each fish family has their own set of parasites, host species belonging to the same taxon share parasite species. High component community similarity among related host species was recorded, demonstrated by high prevalence and abundance, as well as dominance, of autogenic specialist species in each component community. Most autogenic helminth species are numerically and reproductively successful in relatively few host species. Autogenic helminths common in one host species are not common in others. Our findings give empirical support to the idea that low levels of sharing of parasites favor animal coexistence and high species richness, because large phylogenetic differences allow potentially competing animals to consume the same resources without being sensitive of another’s parasites.

“…The present work also confirms the already described patterns of taxonomical structure of helminth fauna of freshwater fishes of Mexico, as early described by Salgado-Maldonado et al [28], [29]. A dominance by the number of species of trematodes and nematodes is evident for all the fauna, for the helminths from each basin, and for each family of fishes [see [2] and papers cited herein].…”

In this paper, we analyse the distributional patterns of adult helminth parasites of freshwater fishes with respect to the main hydrological basins of Mexico. We use the taxonomic distinctness and the variation in taxonomic distinctness to explore patterns of parasite diversity and how these patterns change between zoogeographical regions. We address questions about the factors that determine the variation of observed diversity of helminths between basins. We also investigate patterns of richness, taxonomic distinctness and distance decay of similarity amongst basins. Our analyses suggest that the evolution of the fauna of helminth parasites in Mexico is mostly dominated by independent host colonization events and that intra - host speciation could be a minor factor explaining the origin of this diversity. This paper points out a clear separation between the helminth faunas of northern - nearctic and southern - neotropical components in Mexican continental waters, suggesting the availability of two distinct taxonomic pools of parasites in Mexican drainage basins. Data identifies Mexican drainage basins as unities inhabited by freshwater fishes, hosting a mixture of neotropical and nearctic species, in addition, data confirms neotropical and neartic basins/helminth faunas. The neotropical basins of Mexico are host to a richest and more diversified helminth fauna, including more families, genera and species, compared to the less rich and less diverse helminth fauna in the nearctic basins. The present analysis confirms distance - decay as one of the important factors contributing to the patterns of diversity observed. The hypothesis that helminth diversity could be explained by the ichthyological diversity of the basin received no support from present analysis.
