Two New Gyrodactylus (trematoda: Monogenea) from Cyprinid Fishes with Synopsis of Those Found on North American Fishes.
Gyrodactylus atratuli from the blacknose dace (Rhinichthys atratulus) and the pearl dace (Semotilus margarita) is compared with known species of Gyrodactylus from North American fishes and described as a new species. Gyrodactylus margaritae from the pearl dace (Semotilus margarita) is compared with known species of Gyrodactylus from North American fishes and described as a new species. The aver...

متن کاملPhylogenetic relationships of the North American cyprinid subgenus Hydrophlox.
Notropis is one of the largest genera of North American fishes and is composed of a number of morphologically diagnosed subgroups; however, the validity of many has not been tested in a phylogenetic framework. One such subgroup is the subgenus Hydrophlox, which is composed of brilliantly colored species that engage in the symbiotic reproductive behavior of nest association. Although they have l...
متن کاملBody mass and temperature influence rates of mitochondrial DNA evolution in North American cyprinid fish.
The mass-specific metabolic rate hypothesis of Gillooly and others predicts that DNA mutation and substitution rates are a function of body mass and temperature. We tested this hypothesis with sequence divergences estimated from mtDNA cytochrome b sequences of 54 taxa of cyprinid fish. Branch lengths estimated from a likelihood tree were compared with metabolic rates calculated from body mass a...
متن کاملCyprinid fishes of the genus Neolissochilus in Peninsular Malaysia.
Meristic, morphometric and distributional patterns of cyprinid fishes of the genus Neolissochilus found in Peninsular Malaysia are presented. Based on the current concept of Neolissochilus, only two species are present: N. soroides and N. hendersoni. Neolissochilus hendersoni differs from N. soroides by having lower scale and gill raker counts. Neolissochilus soroides has three mouth types (nor...
