Saccharomyces hybrid yeasts are receiving increasing attention as a powerful model
system to understand adaptation to environmental stress and speciation mechanisms, using …

Forest vulnerability to drought is expected to increase under anthropogenic climate change,
and drought-induced mortality and community dynamics following drought have major …

Mutations and their effects on fitness are a fundamental component of evolution. The effects
of some mutations change in the presence of other mutations, and this is referred to as …

Recent findings in yeast genetics and genomics have advanced our understanding of the
evolutionary potential unlocked by hybridization, especially in the genus Saccharomyces. We …

Near total canopy mortality occurred over several tens of hectares of post oak-blackjack oak
forests in the Cross Timbers of south-central United States in 2008. This event closely …

Adaptation from standing genetic variation is an important process underlying evolution in
natural populations, but we rarely get the opportunity to observe the dynamics of fitness and …

Comparative genome analyses have suggested East Asia to be the cradle of the domesticated
microbe Brewer’s yeast (Saccharomyces cerevisiae), used in the food and biotechnology …

Hybridization between species can either promote or impede adaptation. But we know very
little about the genetic basis of hybrid fitness, especially in nondomesticated organisms, and …

Self-cleaving ribozymes are genetic elements found in all domains of life, but their evolution
remains poorly understood. A ribozyme located in the second intron of the cytoplasmic …

Evolutionary innovations are qualitatively novel traits that emerge through evolution and
increase biodiversity. The genetic mechanisms of innovation remain poorly understood. A …
