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 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 کاملGlobal climate change and North American mammalian evolution
—We compare refined data sets for Atlantic benthic foraminiferal oxygen isotope ratios and for North American mammalian diversity, faunal turnover, and body mass distributions. Each data set spans the late Paleocene through Pleistocene and has temporal resolution of 1.0 m.y.; the mammal data are restricted to western North America. We use the isotope data to compute five separate time series: o...
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 کاملNorth American gross primary productivity: regional characterization and interannual variability
Seasonality and interannual variability in North American photosynthetic activity reflect potential patterns of climate variability. We simulate 24 yr (1983–2006) and evaluate regional and seasonal contribution to annual mean gross primary productivity (GPP) as well as its interannual variability. The highest productivity occurs in Mexico, the southeast United States and the Pacific Northwest. ...
