Adaptive evolution of nontransitive fitness in yeast
eLife, 2020 A common misconception is that evolution is a linear ‘march of progress’, where each organism along a line of descent is more fit than all those that came before it.

Ecology and Evolution, 2021 Biological populations may survive lethal environmental stress through evolutionary rescue. The rescued populations typically suffer a reduction in growth performance and harbor very low genetic diversity compared with their parental populations.

Experimental Evolution: The Rate of Adaptive Evolution [PDF]
Current Biology, 2010 Next-generation sequencing technology allows the identification of molecular changes that have arisen in the genomes of microorganisms undergoing experimental evolution. This permits the elucidation of the molecular evolutionary dynamics in these populations.

Genetic variation in adaptability and pleiotropy in budding yeast
eLife, 2017 Evolution can favor organisms that are more adaptable, provided that genetic variation in adaptability exists. Here, we quantify this variation among 230 offspring of a cross between diverged yeast strains.

Experimental evolution recapitulates natural evolution
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000 Genomes of the closely related bacteriophages ϕX174 and S13 are 5386 bases long and differ at 114 nucleotides, affecting 28 amino acids. Both parental phages were adapted to laboratory culture conditions in replicate lineages and analysed for nucleotide changes that accumulated experimentally.

eLife, 2021 Gene regulatory networks allow organisms to generate coordinated responses to environmental challenges. In bacteria, regulatory networks are re-wired and re-purposed during evolution, though the relationship between selection pressures and evolutionary ...

Experimental evolution gone wild [PDF]
Journal of The Royal Society Interface, 2015 Because of their large population sizes and rapid cell division rates, marine microbes have, or can generate, ample variation to fuel evolution over a few weeks or months, and subsequently have the potential to evolve in response to global change.

EMBO Molecular Medicine, 2013 The gastrointestinal tract is a principal route of entry and site of persistence of human immunodeficiency virus type 1 (HIV‐1). The intestinal mucosa, being rich of cells that are the main target of the virus, represents a primary site of viral ...

Frontiers in Microbiology, 2014 The Vibrionaceae are a genetically and metabolically diverse family living in aquatic habitats with a great propensity toward developing interactions with eukaryotic microbial and multicellular hosts (as either commensals, pathogens, and mutualists). The
