Journal ArticleDOI
Detecting a complex of cryptic species within Neoechinorhynchus golvani (Acanthocephala: Neoechinorhynchidae) inferred from ITSs and LSU rDNA gene sequences.
Andrés Martínez-Aquino,Miriam E. Reyna-Fabián,Rogelio Rosas-Valdez,Ulises Razo-Mendivil,Gerardo Pérez-Ponce de León,Martín García-Varela +5 more
TL;DR: Genetic divergence, in combination with phylogenetic analyses, suggested that the acanthocephalan N. golvani represents a complex of cryptic species, which is composed of at least 3 lineages, and seems to be the result of independent host-switching events from the ancestral population.
Journal ArticleDOI
Phylogenetic analysis of nuclear and mitochondrial DNA reveals a complex of cryptic species in Crassicutis cichlasomae (Digenea: Apocreadiidae), a parasite of Middle-American cichlids
Ulises Razo-Mendivil,Ella Vázquez-Domínguez,Rogelio Rosas-Valdez,Gerardo Pérez-Ponce de León,Steven A. Nadler +4 more
TL;DR: In this paper, the authors obtained nuclear ITS-1 and mitochondrial cox1 sequences from 225 Crassicutis cichlasomae adults collected in 12 species of cichlids from 32 localities to prospect for the presence of cryptic species.
Journal Article
Digenean fauna of amphibians from central Mexico: nearctic and neotropical influences.
G. Pérez-Ponce de León,Virginia León-Règagnon,Luis García-Prieto,Ulises Razo-Mendivil,A. Sanchez-Alvarez +4 more
TL;DR: Twenty-two new host and 21 new locality reports are added to the database of amphibian species from central Mexico, finding 21 digenean species; 4 of them are recorded for the first time in Mexico.
Journal ArticleDOI
A new cryptogonimid (Digenea) from the Mayan cichlid, Cichlasoma urophthalmus (Osteichthyes: Cichlidae), in several localities of the Yucatán Peninsula, Mexico.
TL;DR: Comparison of approximately 1,850 bases of ribosomal DNA, and 400 bases of cytochrome c oxidase subunit I (cox1) strongly supports the status of O. mayae as a new species, as compared to O. manteri collected from cichlids in other localities of Mexico, Belize, and Guatemala.
Journal ArticleDOI
Triple trouble? Invasive poeciliid fishes carry the introduced tilapia pathogen Gyrodactylus cichlidarum in the Mexican highlands.
TL;DR: Evidence is provided that G. cichlidarum, a recognized pathogen which has been co-introduced globally with its cICHlid fish hosts for aquacultural purposes, is able to infect non-related poeciliid fishes inhabiting water bodies adjacent to tilapia farms, thereby potentially increasing its ability to disperse between farms and different river basins.
