The evolution and function of carotenoid hydroxylases in Arabidopsis.
To gain insight into the evolution of xanthophyll synthesis in Arabidopsis thaliana, we analyzed two pairs of duplicated carotenoid hydroxylase enzymes in Arabidopsis thaliana: the cytochrome P450Expand

Allopatric genetic origins for sympatric host-plant shifts and race formation in Rhagoletis
Tephritid fruit flies belonging to the Rhagoletis pomonella sibling species complex are controversial because they have been proposed to diverge in sympatry (in the absence of geographic isolation)Expand

Sequential Sympatric Speciation Across Trophic Levels
A major cause for biodiversity may be biodiversity itself. As new species form, they may create new niches for others to exploit, potentially catalyzing a chain reaction of speciation events acrossExpand

Conditions for sympatric speciation: A diploid model incorporating habitat fidelity and non-habitat assortative mating
SummaryThree types of genes have been proposed to promote sympatric speciation: habitat preference genes, assortative mating genes and habitat-based fitness genes. Previous computer models haveExpand

Phylogeny of the genus Rhagoletis (Diptera: Tephritidae) inferred from DNA sequences of mitochondrial cytochrome oxidase II.
Despite a considerable literature describing the biology of flies in the tephritid genus Rhagoletis, the phylogenetic relationships of the more than 60 species classified within the genus are notExpand

Sequential divergence and the multiplicative origin of community diversity
Significance Understanding how new life forms originate is a central question in biology. Population divergence is usually studied with respect to how single lineages diverge into daughter taxa.Expand
