▪ Abstract Nonindigenous species can bring about a form of extinction of native flora and
fauna by hybridization and introgression either through purposeful introduction by humans …

(1) It has been established by recent work in Palaeontology and Systematics that evolution
has not proceeded at a slow even rate. There have instead been bursts of evolutionary …

The role of hybridization in the origin, maintenance, and loss of biodiversity has been the
subject of speculation and debate for more than two centuries (Linnaeus 1760; Kölreuter …

Hybridization between species is commonplace in plants, but is often seen as unnatural and
unusual in animals. Here, I survey studies of natural interspecific hybridization in plants and …

Biologists have forever sought to understand how species arise and persist. Historically,
species that rarely interbreed, or are reproductively isolated, were considered the norm …

The increasing number of invasive exotic plant species in many regions and the continuing
alteration of natural ecosystems by humans promote hybridization between previously …

This review deals with natural hybridization, an important subject in conservation biology.
Natural hybridization is defined as the secondary contact between two populations that have …

Rather, nature blends only specific sets of traits, each tailored to enhance sur vival and
reproduction. Other combi nations are conceivable, but, like the sunflower-camel, they …

Rates of hybridization and introgression are increasing dramatically worldwide because of
translocations of organisms and habitat modifications by humans. Hybridization has …

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