Genetic correlations concentrate genetic variation in certain directions of the multivariate
phenotype. Adaptation and, under some models, plasticity is expected to occur in the …

Premise Genetic variation influences the potential for evolution to rescue populations from
impacts of environmental change. Most studies of genetic variation in fitness‐related traits …

Accurately predicting responses to selection is a major goal in biology and important for
successful crop breeding in changing environments. However, evolutionary responses to …

During the last few decades, biologists have made remarkable progress in understanding
the fundamental processes that shape life. But despite the unprecedented level of …

The repeated evolution of the same trait in different lineages provides powerful natural
experiments to study the phenotypic and genotypic predictability of how traits are gained …

Floral microbes are an overlooked aspect of the extended floral phenotype. Through altering
floral nectar chemistry, they can mediate interactions between flowers, pollinators, and other …

Adaptive plasticity allows populations to cope with environmental variation but is expected to
fail as conditions become unfamiliar. In novel conditions, populations may instead rely on …

Pollinator-driven evolution in plants. Most of my scientific work is in this research field. My
older work focusses on orchids, where I have worked on mechanisms and evolution of floral …
