The influence of host ecology and biogeography on the helminth species richness of freshwater fishes in Mexico

2012

Freshwater fish helminths, the most well known Mexican vertebrate parasites, include approximately 260 species (platyhelminthes, acanthocephalans, nematodes, and hirudineans). The distribution patterns of adult helminth diversity (throughout parasite and host groups and hydrological regions) are described and the effects of host traits and environmental and geographical factors on diversity are evaluated. Adult helminths include 160 species, parasitizing 149 fish species of 23 families distributed in 21 regions. Nematoda was the most species-rich (>50 species). Cichlidae harboured rich helminth assemblages, with widespread parasites. By contrast, Atherinopsidae and Goodeidae showed relatively poor helminth assemblages, including specific parasites with narrow distribution. Helminth richness in southeastern Mexico was higher than northern or central regions. Non-parametric richness estimators were used to avoid confusion in comparisons with unequal sampling efforts. Bootstrap values, the method with the best performance, indicated that estimated richness shows the same distribution pattern that observed richness. Non-phylogenetic and phylogenetic analyses were used to determine the role of different factors in the parasite diversification. The distribution range was the most important richness predictor (widespread fishes harbour richer parasite assemblages), although interactions between this variable and others such as trophic level, latitude, habitat temperature and precipitation are also important. Likewise, biogeographical factors can also affect parasite diversity.

“…The inclusion of the new sequences of O. pedicathedrae showed a phylogenetic convergence between O. pedicathedrae and O. fimbriatus compared to O. furcatus. Opecoeloides pedicathedrae was reported only off the coast of Brazil [3,7,8], while Opecoeloides fimbriatus was reported from the Western North Atlantic [22,39,40], both sides of the Panama Isthmus [41], and the Pacific coast of Mexico [23,42]. Opecoeloides furcatus was reported from Mediterranean waters [21,43,44], off the Canary Islands [45], off the coast of Belgium [46], and from Japan [47].…”

Opecoeloides Odhner, 1928, is represented by 19 valid species found in marine fish, of which five have been reported in Brazil. Specimens of Opecoeloides pedicathedrae Travassos, Freitas & Bührnheim, 1966, were collected from the intestine of smooth weakfish Cynoscion leiarchus, a new host record, from off the coast of Rio de Janeiro, Brazil. They were examined using light and confocal laser microscopy. New partial sequences of 18S and 28S rDNA genes of O. pedicathedrae were obtained. Bayesian inference analysis on the partial 28S rDNA dataset resulted in a phylogram in which O. pedicathedrae formed a well-supported clade with Opecoeloides fimbriatus and Opecoeloides furcatus. The K2p distance between O. pedicathedrae and O. fimbriatus was 0.34%, with 3 divergent nucleotides; and between O. pedicathedrae and O. furcatus was 4.18%, with 38 divergent nucleotides. A Bayesian-inference phylogenetic tree based on the 18S rDNA recovered two main clades with five subfamilies. A clade of Opecoelinae showed that O. pedicathedrae was closer to Pseudopecoeloides tenuis; the K2p distance between these species was 2.14%, with 28 divergent nucleotides. The new nucleotide sequences presented inclusion of a phylogenetic analysis that can help to clarify the understanding of this complex taxon.

“…Esto puede estar muy relacionado con el tipo de géneros encontrados, ya que 2 de ellos: Kalicephalus y Cruzia, tienen ciclos de vida directos, y su infección es continua y común; esto aunado a que muchas de las presas de la boa son mamíferos que son parasitados por nemátodos de los géneros antes mencionados y que pasan al sistema digestivo una vez que la presa ha sido digerida. Este patrón no es raro, ya que se sabe que los 2 grupos de helmintos con la mayor riqueza de especies en los vertebrados de México, incluyendo a los reptiles, son los Nematoda y Digenea (Pérez-Ponce de León y García-Prieto, 2001).…”

Brasil, es considerado como uno de los países con mayor riqueza específica de reptiles en el mundo (Semarnat, 2008), con 804 especies descritas (Flores-Villela y Canseco-Márquez, 2004), de las cuales un poco más del 18% (145) se presentan en la península de Yucatán (Lee, 2000). Particularmente, de los 3 estados de México que conforman dicha península, Quintana Roo tiene una de las mayores faunas de reptiles, con 106 especies (Calderón-Mandujano y Cedeño-Vázquez, 2011). Como parte importante de esta riqueza, se encuentra a la boa o mazacuata, B. constrictor Linnaeus, 1758, que a diferencia de otras serpientes, no es venenosa, pero sí peligrosa por la cantidad de dientes que posee y su hábito constrictor (Sánchez et al., 2004). Se alimenta, principalmente de aves, reptiles y mamíferos
