Dissecting Dispensability
NEWS AND VIEWS Dissecting dispensability Laurence D Hurst & Csaba Pál Like most organisms, yeast has relatively few genes that are necessary for viability. The presence of a duplicate gene elsewhere in the genome underpins many cases of dispensability. A new study suggests that the backup mechanism is more complex than previously assumed and requires feedback loops that ensure transcriptional upregulation of the duplicate. Four-fifths of yeast’s genes are not essential there is no relationship between the degree of The idea that the process involves active for viability1.

Detecting Selection on Noncoding Nucleotide Variation: Methods and Applications Abstract There has been a long tradition in molecular evolution to study selective pressures operating at the amino-acid level. But protein-coding variation is not the only level on which molecular adaptations occur, and it is not clear what roles non-coding variation has played in evolutionary history, since they have not yet been systematically explored. In this dissertation I systematically explore several aspects of selective pressures of noncoding nucleotide variation: The first project (Chapter 2) describes research on the determinants of eukaryotic translation dynamics, which include selection on non-coding aspects of DNA variation. Deep sequencing of ribosome-protected mRNA fragments and polysome gradients in various eukaryotic organisms have revealed an intriguing pattern: shorter mRNAs tend to have a greater overall density of ribosomes than longer mRNAs. There is debate about the cause of this trend. To resolve this open question, I systematically analysed 5’ mRNA structure and codon usage patterns in short versus long genes across 100 sequenced eukaryotic genomes. -

ABSTRACT Methods for inference and interpretation of evolutionary quantitative genetic parameters, and for prediction of the response to selection, are best developed for traits with normal distributions. Many traits of evolutionary interest, including many life history and behavioral traits, have inherently nonnormal distributions. The generalized linear mixed model (GLMM) framework has become a widely used tool for estimating quantitative genetic parameters for nonnormal traits. However, whereas GLMMs provide inference on a statistically convenient latent scale, it is often desirable to express quantitative genetic parameters on the scale upon which traits are measured. The parameters of fitted GLMMs, despite being on a latent scale, fully determine all quantities of potential interest on the scale on which traits are expressed. We provide expressions for deriving each of such quantities, including population means, phenotypic (co)variances, variance components including additive genetic (co)variances, and parameters such as heritability. -

Land Smith 2021 MELS ii Abstract Sina Queyras, in the essay “Lyric Conceptualism: A Manifesto in Progress,” describes the Lyric Conceptualist as a poet capable of recognizing the effects of disparate movements and employing a variety of lyric, conceptual, and language poetry techniques to continue to innovate in poetry without dismissing the work of other schools of poetic thought. Queyras sees the lyric conceptualist as an artistic curator who collects, modifies, selects, synthesizes, and adapts, to create verse that is both conceptual and accessible, using relevant materials and techniques from the past and present. This dissertation responds to Queyras’s idea with a collection of original poems in the lyric conceptualist mode, supported by a critical exegesis of that work. -
