Analyses of complete cytochrome b sequences from all species of cranes (Aves: Gruidae) reveal aspects of sequence evolution in the early stages of divergence. These DNA sequences are > or = 89% identical, but expected departures from random substitution are evident. Silent, third-position pyrimidine transitions are the dominant substitution type, with… (More)
ki ctes over whether molecular sequence data should be partitioned for phylogenetic analysis often confound two types of heterogeneity among partitions. We distinguish historical heterogeneity (i.e., different partitions have different evolutionary relationships) from dynamic heterogeneity (i.e., different partitions show different patterns of sequence… (More)
A complete suite of comparisons among six bandicoot species and one outgroup marsupial was generated using the hydroxyapatite chromatography method of DNA/DNA hybridization; heterologous comparisons were also made with three other bandicoot taxa. Matrices of delta Tm's, delta modes, and delta T50Hs were generated and corrected for nonreciprocity, homoplasy,… (More)
Sminthopsis is the most speciose genus of living dasyurid marsupials and, along with its close relatives Antechinomys and Ningaui, constitutes the clade Sminthopsini. Phylogenetic relationships among the 23 species in this clade have been the subject of much morphological and molecular investigation, including a recent integration of penis morphology (in… (More)
Data from DNA-DNA hybridization studies provide a means by which to estimate variation in molecular evolutionary rates within and among taxonomic groups. Statistical analyses (ANOVA and F-ratio tests) of such data for the 14 species of cranes (Aves:Gruidae) suggest that rates of single-copy DNA evolution vary significantly between members of the two crane… (More)
Figure 3 (p. 1310) in the report "A 115-kD polypeptide immunologically related to erythrocyte band 3 is present in Golgi membranes" by S. Kellokumpu et al. (2 Dec., p. 1308) was incorrectly printed. The correct figure is reproduced below.
