Although hybrid crop varieties are among the most popular agricultural innovations, the
rationale for hybrid crop breeding is sometimes misunderstood. Hybrid breeding is slower …

▪ Abstract Floral evolution has often been associated with differences in pollination
syndromes. Recently, this conceptual structure has been criticized on the grounds that …

As populations become increasingly fragmented, managers are often faced with the
dilemma that intentional hybridization might save a population from inbreeding depression …

Plant invasions often involve rapid evolutionary change. Founder effects, hybridization, and
adaptation to novel environments cause genetic differentiation between native and …

In plant conservation, restoration (the augmentation or reestablishment of an extinct
population or community) is a valuable tool to mitigate the loss of habitat. However …

Indirect genetic effects (IGEs) are environmental influences on the phenotype of one
individual that are due to the expression of genes in a different, conspecific, individual …

Epistasis for fitness means that the selective effect of a mutation is conditional on the genetic
background in which it appears. Although epistasis is widely observed in nature, our …

Now updated for its second edition, Population Genetics is the classic, accessible
introduction to the concepts of population genetics. Combining traditional conceptual …

Molecular markers appear to be poor indicators of heritable variation in adaptive traits.
Direct comparison of population structure in markers with that in traits is made possible by …

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