Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Environmental gradients are very common and many plant species respond to them through
adaptive genetic change. This can be a first step along a continuum of change that leads …

Adaptive divergence and speciation may happen despite opposition by gene flow.
Identifying the genomic basis underlying divergence with gene flow is a major task in …

Speciation genomic studies aim to interpret patterns of genome-wide variation in light of the
processes that give rise to new species. However, interpreting the genomic “landscape” of …

Hybridization can facilitate both evolutionary diversification and extinction and has had a
critical role in plant evolution, with c. 25% of species known to hybridize in some temperate …

Combining hybrid zone analysis with genomic data is a promising approach to
understanding the genomic basis of adaptive divergence. It allows for the identification of …

Species delimitation is a first step for realizing the extent of biodiversity and is relevant for all
downstream applications in biology. The production of large genome-scale datasets for non …

Pollination is the transfer of pollen grains from the stamens to the stigma, an essential
requirement of sexual reproduction in flowering plants. Cross-pollination increases genetic …

Bemisia tabaci threatens production of cassava in Africa through vectoring viruses that
cause cassava mosaic disease (CMD) and cassava brown streak disease (CBSD). B. tabaci …

Inferring the history of divergence between species in a framework that permits the presence
of gene flow has been crucial for characterizing the “gray zone” of speciation, which is the …
