malinche was not included in any of those studies. Xiphophorus malinche has been the focus of the variety of behavioral ecology studies (Culumber et al., 2012 Verzijden et al., 2012), but, to date, only 4 species of Xiphophorus have been examined for helminth parasites (Salgado-Maldonado et al., 2004, 2005 Salgado-Maldonado, 2006), and X. Its distribution is restricted to headwaters and highland streams of the Río Pánuco (Kallman and Kazianis, 2006 Culumber et al., 2011). Xiphophorus malinche Rauchengerber, Kallman and Morizot, 1990 (Highland swordtail) is 1 of 9 members of the clade that inhabits the tributaries of the Río Pánuco basin. ![]() Several studies of the phylogeny of the genus have been conducted (e.g., Meyer et al., 1994 Marcus and McCune, 1999) and the results support the recognition of 3 principal clades. In the Mexican drainages, the species are found in parts of the coastal plain and on the eastern to southeastern slopes of the Sierra Madre Oriental, but never beyond the barrier range of the Mexican plateau (Kallman and Kazianis, 2006). The genus Xiphophorus (Pisces: Poeciliidae) nominally has 26 species, commonly called swordtails or platyfish, which are distributed in freshwater streams from northeastern México to eastern Honduras. Palabras clave: componente de comunidad, infracomunidad, sierra Madre Oriental, prevalencia, abundancia, diversidad. Las diferencias observadas en este estudio pueden ser atribuidas a factores bióticos y abióticos resultado de la separación geográfica de las localidades durante la orogenia de la sierra Madre Oriental, que restringió a los peces a cuerpos de agua aislados. vaginoclastrum fue más abundante en peces de talla grande. fué más abundante en peces pequeños, pero Ur. La abundancia de helmintos y la longitud patrón de los peces están correlacionadas. La riqueza de especies, la abundancia y la diversidad se analizaron tanto a nivel de componente de comunidad como de infracomunidad. Sólo 2 especies de helmintos fueron encontradas en ambas localidades. Las demás especies se encontraron en baja abundancia. La especie de monogéneo resultó ser la más frecuente y abundante en las comunidades. 1 especie de monogéneo adulto, Urocleidoides vaginoclastrum 1 céstodo adulto, Bothriocephalus acheilognathi, y 1 nemátodo adulto Rhabdochona xiphophori. Se registraron 5 especies de helmintos: 2 digéneos, Paracreptotrema sp. Se compararon y examinaron las comunidades de helmintos de peces de Xiphophorus malinche de 2 localidades de la cuenca del río Pánuco (Chicayotla y Malila), Hidalgo, México. Key words: component community, infracommunity, Sierra Madre Oriental, prevalence, abundance, diversity. Differences observed in this study can be attributed to abiotic and biotic environmental factors resulting from the geographic separation of these localities during to the orogeny of the Sierra Madre Oriental that restricted fish to isolated headwaters. vaginoclastrum showed the opposite pattern, high abundance in larger fish. Abundance of helminths and fish standard length were correlated. The observed species richness, individual abundance, and diversity were low at component community and infracommunity levels. ![]() Only 2 species of helminth were found at both localities. The remaining species were rare and found at low mean abundance. ![]() vaginoclastrum was the most frequent and abundant species. an adult monogenean, Urocleidoides vaginoclastrum an adult cestode, Bothriocephalus acheilognathi, and an adult nematode, Rhabdochona xiphophori. ![]() Five taxa of helminths were recovered: 2 digeneans, adults of Paracreptotrema sp. The parasite community structure of the 2 localities was examined and compared. 20, Fraccionamiento Las Playas, 39390 Acapulco, Guerrero, México.Ī total of 141 highland swordtails, Xiphophorus malinche, were collected from 2 localities in the Pánuco river drainage (Chicayotla and Malila) from Hidalgo, México. * Laboratorio de Ecología, Unidad Académica de Ecología Marina, Universidad Autónoma de Guerrero.
