john steinbeck: friend of the american common man
in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...
15 صفحه اولMolecular phylogenetics of western North American frogs of the Rana boylii species group.
Phylogenetic relationships among frogs of the genus Rana from western North America are investigated using 2013 aligned bases of mitochondrial DNA sequence from the genes encoding ND1 (subunit one of NADH dehydrogenase), tRNA(Ile), tRNA(Gln), tRNA(Met), ND2, tRNA(Trp), tRNA(Ala), tRNA(Asn), tRNA(Cys), tRNA(Tyr), and COI (subunit I of cytochrome c oxidase), plus the origin for light-strand repli...

Phylogenetic relationships among frogs of the genus Rana from western North America are investigated using 2013 aligned bases of mitochondrial DNA sequence from the genes encoding ND1 (subunit one of NADH dehydrogenase), tRNAIle, tRNAGln, tRNAMet, ND2, tRNATrp, tRNAAla, tRNAAsn, tRNACys, tRNATyr, and COI (subunit I of cytochrome c oxidase), plus the origin for light-strand replication (OL) betw...
متن کاملThe role of exotic species in homogenizing the North American flora.
Exotic species have begun to homogenize the global biota, yet few data are available to assess the extent of this process or factors that constrain its advance at global or continental scales. We evaluate homogenization of vascular plants across America north of Mexico by comparing similarity in the complete native and exotic floras between states and provinces of the USA and Canada. Compared w...
متن کاملSpatial Autocorrelation and Local Disappearances in Wintering North American Birds
I examined the degree to which population sizes of North American wintering birds exhibit spatial synchrony (autocorrelation) and local disappearances based on 30 yr of Christmas Bird Counts. The primary goal of these analyses was to determine whether processes expected in metapopulations, including low spatial synchrony, frequent local disappearances, and colonization leading to population res...
