Overall, our results provide a genome-wide portrait of divergence and introgression associated with adaptation and speciation in an iconic butterfly radiation.
In general, it is assumed that a complex suite of geologic, climatic, and population genetic forces have led to divergence and speciation in allopatry, where a reproductive barrier effectively divides an ancestral species into two populations of roughly equal size.
This was examined by determining dissolved As concentrations and speciation in different zones of an aquifer characterized by different chemical conditions owing to land-disposal of dilute sewage effluent to the aquifer.
Geoff Oxford is a biologist at the University of York and an authority on both colour variation and speciation in spiders.
Imaging element distribution and speciation in plant cells.
An overview of evolution, systematics, population biology, cytogenetics, molecular biology and speciation in Ctenomys.
In a sense, it was reintegrating the proper role of geography into evolutionary theory in general, and speciation in particular, that allowed them to make key predictions about the nature of species and speciation in the fossil record.
Although our study has provided some insight into the genomic architecture of M S divergence, two additional formidable challenges remain for understanding ecological adaptation and speciation in A. gambiae.
Xue, X., Stebbins, J. F., Kanzaki, M. & Trønnes, R. G. Silicon coordination and speciation changes in a silicate liquid at high pressures.
To determine the relative timings of polyploidy and speciations in the legumes, we sequenced a large portion of the transcriptome of C. fasciculata (Cf) and examined the phylogenetic placements of a large number of these sequences in gene families relative to sequences from G. max (Gm), M. truncatula (Mt), and V. vinifera (Vv).
