Cytochrome b and D-loop nucleotide sequences were used to study patterns of molecular evolution and phylogenetic relationships between the pheasants and the partridges, which are thought to form two closely related monophyletic galliform lineages. Our analyses used 34 complete cytochrome b and 22 partial D-loop sequences from the hypervariable domain I of(More)
New crop varieties containing traits such as enhanced nutritional profiles, increased yield, and tolerance to drought are being developed. In some cases, these new traits are dependent on small RNAs or regulatory proteins such as transcription factors (TF) that modify the expression of endogenous plant genes. To date, the food and feed safety of genetically(More)
We examined mate preference behavior in red jungle fowl, Gallus gallus, to determine if the mechanism of mate preference used by females was relative or absolute. Under a relative model, females compare males and prefer the one with the most exaggerated form of secondary sex character, regardless of where the proffered males lie along the population(More)
This paper examines the consequences of accounting scandals to top management, top financial officers, and outside auditors. We examine a sample of 518 U.S. public companies that announced earnings-decreasing restatements during the 1997-2002 period and an industry-size matched sample of control firms. Using logistic regressions that control for other(More)
The entire mitochondrial DNA control region (mtDNA CR) and cytochrome b (cyt b) genes were sequenced in 10 of the 11 extant species of gallopheasants (Lophura). The cyt b from L. diardi and L. ignita showed unusual leucine-coding codons at the expected terminal 3' end of the gene. Presence of conserved functional motifs in the inferred amino acid sequences,(More)
Afropavo congensis, the Congo peafowl, has long fascinated ornithologists because of its uncertain phylogenetic position and unusual geographic distribution. While some researchers have placed Afropavo as a sister taxon to the true peafowl, Pavo species, others have suggested relationships with the guineafowl or an Old World partridge, Francolinus. These(More)
We examine whether conflicts of interest with investment banking and brokerage lead analysts to issue optimistic stock recommendations and whether investors are misled by such biases. Using a unique dataset that contains the annual revenue breakdown of analyst employers, we construct quantitative measures of the magnitude of potential conflicts faced by(More)
We investigated multiple paternity in acorn woodpeckers (Melanerpes formicivorus) from central New Mexico by starch-gel electrophoresis. Seven of thirty-one presumptive genetic loci were polymorphic. Multiple paternity was revealed in one of three multi-male groups sampled on the basis of offspring and adult electrophoretic phendtypes, and was suggested in(More)
