Evolution of gene expression across brain regions in behaviorally divergent deer mice

This study examines gene expression differences across brain regions in two deer mouse species and their hybrids, finding widespread interspecific variation and regional modularity in gene regulation.

A direct experimental test of Ohno's hypothesis

This study experimentally tests Ohno's hypothesis by evolving fluorescent protein genes in E. coli, finding that double-copy populations show increased mutational robustness and diversity but not accelerated phenotypic evolution.

Environment-dependent epistasis increases phenotypic diversity in gene regulatory networks

The paper investigates environment-dependent epistasis in gene regulatory networks using synthetic biology in E. coli, finding that it increases phenotypic diversity through nonlinear interactions.

Acute Cytomegalovirus Infection Modulates the Intestinal Microbiota and Targets Intestinal Epithelial Cells

This study shows that acute CMV infection alters gut microbiota and targets intestinal epithelial cells, leading to colitis in immunocompetent hosts.

Secondary environmental variation creates a shifting evolutionary watershed for the methyl- parathion hydrolase enzyme

The paper shows that secondary environmental factors influence the evolutionary adaptation of an enzyme by shifting the adaptive landscape and altering fitness peaks.

Behavioural mechanisms underlying the evolution of cooperative burrowing in Peromyscus mice

The paper investigates how Peromyscus mice adapt their burrowing behavior when digging individually versus with partners, finding that cooperative digging results in longer burrows due to increased social cohesion in opposite-sex pairs.

The genetics of morphological and behavioral island traits in deer mice

This study investigates genetic and environmental influences on morphological and behavioral traits in deer mice from Saturna Island and mainland populations, finding heritable and plastic responses.

Higher-order epistatic networks underlie the evolutionary fitness landscape of a xenobiotic- degrading enzyme

This study identifies five mutations that enable the evolution of a xenobiotic-degrading enzyme and shows that higher-order epistasis shapes its adaptive landscape and substrate specificity.
