Helminth diversity of two anurans: Rhinella marina and Incilius valliceps (Anura: Bufonidae) from lagunas de Yalahau, Yucatán, Mexico

Diversity of Acanthocephala parasites in Neotropical amphibians

“…One of the species with the highest number of records as host of acanthocephalans was Rhinella marina, which was reported with high prevalence (97%) (Toledo et al 2017). Rhinella marina is distributed from Texas through Mexico and Central America and extends all the way to Brazil (Campbell 1998;Lee 1996;Espínola-Novelo et al 2017). It has become an invasive species in several countries around the world, including islands, with reported occurrences in Australia, the southern United States, Hawaii, Fiji, the Philippines, Taiwan, and Europe.…”

Community structure of the helminths of Lithobates spectabilis (Anura: Ranidae) from two localities in the Biosphere Reserve Barranca de Metztitlán, Hidalgo, Mexico

“…The presence or absence of particular species of helminth in each locality can be related to the type of life cycle of the parasite present (Poulin, 1997) and the presence of potential intermediate hosts (Paredes-Calderón et al, 2004). The behavior of frogs in their respective localities is also thought to affect β-diversity (Bolek & Coggins, 2003;Espínola-Novelo et al, 2017;Hamann et al, 2006a;McAlpine, 1997;Muzzall & Mychek-Londer, 2014;Romero-Mayén et al, 2016;Santos & Amato, 2010;Yáñez-Arenas & Guillén-Hernández, 2010). Local differences in the strength of these factors, and interactions between the factors present in given localities, generates dissimilarity in the structure of the communities of helminths at local levels, which, combined with local environmental factors, generate β-diversity.…”

“…The only study employing Hill numbers in describing communities of helminths in Mexican anurans is that of Espínola-Novelo et al (2017). In that study, the authors quantified the ecological parameters of the helminth communities of Rhinella marina Linnaeus, 1758 and Incilius valliceps Wiegmann, 1833 from Lagunas de Yalahau, Yucatán, Mexico.…”

“…One of the important aspects of the Hill numbers is their usefulness for making predictions about the richness and diversity of communities of similar organisms (Jost, 2006(Jost, , 2007. Based on the study of the helminth community of the 2 species of toads (I. valliceps and Rhinella marina) by Espínola-Novelo et al (2017), the anurans in a more terrestrial environment would have q values lower than those in a combination of aquatic-terrestrial environments; in that case, the toads are in the same general locality, but they have different habitat preferences. In the present study, the frogs in Las Pilas are in an aquatic-terrestrial environment and those in Metznoxtla are in an aquatic one.…”

“…Approximately, 402 species of amphibians have been described from Mexico (Frots, 2018;Parra-Olea et al, 2014), of which only 66 have been studied from a helminthological perspective; this number represents only about 18% of all Mexican species (Cabrera-Guzmán et al, 2021). Most of those works have focused mainly on taxonomic descriptions, lists of species, or population level studies (Cabrera-Guzmán, 2002;Cabrera-Guzmán et al, 2007Galicia-Guerrero et al, 2000;León-Règagnon et al, 2005;Velázquez-Urrieta & León-Règagnon, 2018), and only a few reports of the ecological structure of helminth communities (Adán-Torres et al, 2018;Espínola-Novelo et al, 2017;Goldberg et al, 2001;Mata-López et al, 2013;Paredes-Calderón et al, 2004;Ruiz-Torres et al, 2017;Zelmer et al, 2004). The only helminthological studies of amphibians from Hidalgo state are the helminth fauna of Ambystoma velasci (Dugès, 1888), Lithobates spectabilis Hillis andFrost, 1985 andRhinella horribilis (Wiegmann, 1833) (Falcón-Ordaz et al, 2014Pulido-Flores et al, 2009;Rodríguez-Amador et al, 2013).…”
