Interspecific gene flow in sympatric oaks.
Variation of chloroplast DNA and nuclear ribosomal DNA (DNA encoding ribosomal RNA) was studied for five species of white oak native to the eastern United States. Although these species differ in many morphological characters and have different (though overlapping) geographical ranges and ecological tolerances, they are interfertile and often grow in mixed stands, and hybrids are occasionally f...
متن کاملThe White Oaks Laccoliths
About 12 miles to the northeast of Carrizozo lies the “ghost town” of White Oaks. This once thriving mining community rests in a small valley surrounded by three wrinkled and rounded mountain peaks: the remains of a ancient cluster of laccoliths (see attached Figure 1). To the northwest lies Lone Mountain with its associated peak, Baxter Mountain, while to the southeast lies Patos Mountain and ...
متن کاملEuropean Lampreys: New Insights on Postglacial Colonization, Gene Flow and Speciation
Ice ages are known to be the most dominant palaeoclimatic feature occurring on Earth, producing severe climatic oscillations and consequently shaping the distribution and the population structure of several species. Lampreys constitute excellent models to study the colonization of freshwater systems, as they commonly appear in pairs of closely related species of anadromous versus freshwater res...
متن کاملChloroplast DNA footprints of postglacial recolonization by oaks.
Recolonization of Europe by forest tree species after the last glaciation is well documented in the fossil pollen record. This spread may have been achieved at low densities by rare events of long-distance dispersal, rather than by a compact wave of advance, generating a patchy genetic structure through founder effects. In long-lived oak species, this structure could still be discernible by usi...
متن کاملWind-dispersed pollen mediates postglacial gene flow among refugia.
A long-term genetic legacy of refugial isolation has been postulated and was demonstrated for maternal refugial lineages for numerous plant and animal species. The lineages were assumed to have remained separated from each other for several glacial periods. The conifer Abies alba Miller, silver fir, is an excellent model to test whether pollen-mediated gene flow may eliminate the genetic imprin...
