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 …

Although the potential genetic risks associated with rare or endangered plants and small
populations have been discussed previously, the practical role of population genetics in …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Current rates of climate change require organisms to respond through migration, phenotypic
plasticity, or genetic changes via adaptation. We focused on questions regarding species' …

bestiae in combat 18 2.3 Pixelled web image of Caiman latirostris 'in the wild' 20 2.4 …

Invasive species are of great interest to evolutionary biologists and ecologists because they
represent historical examples of dramatic evolutionary and ecological change. Likewise …

The production of extreme or 'transgressive'phenotypes in segregating hybrid populations
has been speculated to contribute to niche divergence of hybrid lineages. Here, we assess …

The origin of new homoploid species via hybridization is theoretically difficult because it
requires the development of reproductive isolation in sympatry. Nonetheless, this mode is …

Publisher Summary This chapter discusses the gene flow and introgression from
domesticated plants into their wild relatives. Domesticated plants cannot be regarded as …
