| biology of crassicutis cichlasomae, a parasite of cichlid fishes in mexico and central america. | field study on the biology of crassicutis cichlasomae manter, 1936 (digenea: homalometridae) was carried out in a small swamp in a limestone factory near mérida, yucatán, mexico. aquatic snails, littorina (littoridinopis) angulifera, harbouring c. cichlasomae rediae, cercariae and metacercariae, served both as the first and second intermediate hosts. feeding experiments confirmed the conspecificity of metacercariae from naturally infected snails with adults from naturally infected fish. gravid c ... | 1995 | 7622794 |
| cenotes (sinkholes) of the yucatan peninsula, mexico, as a habitat of adult trematodes of fish. | examination of a total of 581 fish specimens of 15 species from 39 cenotes (sinkholes) in the yucatan peninsula, southeastern mexico, revealed the presence of 10 species of adult trematodes. these were as follows: saccocoelioides sogandaresi lumsden, 1963, saccocoelioides sp. (family haploporidae), cichlasotrema ujati pineda et andrade, 1989 (angiodictyidae), crassicutis cichlasomae manter, 1936 (homalometridae), magnivitellinum simplex kloss, 1966 (macroderoididae), stunkardiella minima (stunka ... | 1995 | 9599426 |
| discordant genetic diversity and geographic patterns between crassicutis cichlasomae (digenea: apocreadiidae) and its cichlid host, "cichlasoma" urophthalmus (osteichthyes: cichlidae), in middle-america. | genetic analyses of hosts and their parasites are key to understand the evolutionary patterns and processes that have shaped host-parasite associations. we evaluated the genetic structure of the digenean crassicutis cichlasomae and its most common host, the mayan cichlid "cichlasoma" urophthalmus, encompassing most of their geographical range in middle-america (river basins in southeastern mexico, belize, and guatemala together with the yucatan peninsula). genetic diversity and structure analyse ... | 2013 | 23859473 |
