Hybridization has played an important role in the evolution of many lineages. With the
growing availability of genomic tools and advancements in genomic analyses, it is becoming …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Asian rice, Oryza sativa is a cultivated, inbreeding species that feeds over half of the world's
population. Understanding the genetic basis of diverse physiological, developmental, and …

Speciation is characterized by the evolution of reproductive isolation between two groups of
organisms. Understanding the process of speciation requires the quantification of barriers to …

When plants establish outside their native range, their ability to adapt to the new
environment is influenced by both demography and dispersal. However, the relative …

Many studies have identified quantitative trait loci (QTLs) that contribute to continuous
variation in heritable traits of interest. However, general principles regarding the distribution …

Germination timing of Arabidopsis thaliana displays strong plasticity to geographic location
and seasonal conditions experienced by seeds. We identified which plastic responses were …

Global environmental change is altering the selection regime for all biota. The key selective
factors are altered mean, variance and seasonality of climatic variables and increase in CO2 …

Natural hybridization between closely related taxa is a common phenomenon in both plants
and animals. Hybridization has often been viewed as a destructive force that could erode …

There is reason to suspect that hidden reaction norms (variation that is phenotypically
expressed only after changes in internal or external environmental conditions) may store an …
