Scholarly Works - Journal articles

Major publications in the critical care pharmacotherapy literature: February 2012 through February 2013.

Journal article American journal of health-system pharmacy : AJHP : official journal of the American Society of Health-System Pharmacists · January 2014 PurposeRecent impactful additions to the professional literature on the role of pharmacotherapy in treating the critically ill are summarized.SummaryAn unusually large number of updated practice guidelines and other publications with broa ...

Slip-sliding away: serial changes and homoplasy in repeat number in the Drosophila yakuba homolog of human cancer susceptibility gene BRCA2.

Journal article PloS one · June 2010 Several recent studies have examined the function and evolution of a Drosophila homolog to the human breast cancer susceptibility gene BRCA2, named dmbrca2. We previously identified what appeared to be a recent expansion in the RAD51-binding BRC-repeat arr ... Full text Open Access Cite

RNase 1 genes from the family Sciuridae define a novel rodent ribonuclease cluster.

Journal article Mammalian genome : official journal of the International Mammalian Genome Society · November 2009 The RNase A ribonucleases are a complex group of functionally diverse secretory proteins with conserved enzymatic activity. We have identified novel RNase 1 genes from four species of squirrel (order Rodentia, family Sciuridae). Squirrel RNase 1 genes enco ... Full text Cite

Differing rates of macroevolutionary diversification in arboreal squirrels

Journal article Current Science · October 10, 2008 Current diversity is the result of macroevolutionary processes of origination and extinction of lineages through time. Here we make use of a fossil-calibrated molecular-clock phylogeny of modern squirrel genera to estimate both rates of 'birth' and 'death' ... Cite

The effects of Cenozoic global change on squirrel phylogeny.

Journal article Science (New York, N.Y.) · March 2003 By modifying habitats and creating bridges and barriers between landmasses, climate change and tectonic events are believed to have important consequences for diversification of terrestrial organisms. Such consequences should be most evident in phylogeneti ... Full text Cite

Morphometrics in development and evolution

Journal article American Zoologist · January 1, 2000 SYNOPSIS. Morphometric approaches facilitate the analysis of quantitative variation in form, typically becoming most useful for the study of organisms that have completed morphogenesis and arc at differing stages of growth. Recent conceptual and technical ... Full text Cite

Genetic Architecture of a Morphological Shape Difference Between Two Drosophila Species

Journal article Genetics · January 2000 http://www.genetics.org/cgi/content/abstract/154/1/299 ... Cite

An introgression analysis of quantitative trait loci that contribute to a morphological difference between Drosophila simulans and D. mauritiana.

Journal article Genetics · February 1997 Drosophila simulans and D. mauritiana differ markedly in morphology of the posterior lobe, a male-specific genitalic structure. Both size and shape of the lobe can be quantified by a morphometric variable, PCl, derived from principal components and Fourier ... Full text Cite

Genetic analysis of a morphological shape difference in the male genitalia of Drosophila simulans and D. mauritiana.

Journal article Genetics · April 1996 Two closely related species of Drosophila, D. simulans and D. mauritiana, differ markedly in morphology of the posterior lobe of the male genital arch. Both size and shape aspects of lobe variation can be quantified by a morphometric descriptor based on el ... Full text Cite

Differences in crossover frequency and distribution among three sibling species of Drosophila.

Journal article Genetics · February 1996 Comparisons of the genetic and cytogenetic maps of three sibling species of Drosophila reveal marked differences in the frequency and cumulative distribution of crossovers during meiosis. The maps for two of these species, Drosophila melanogaster and D. si ... Full text Cite
