Experimental evidence of genome‐wide impact of ecological selection during early stages of speciation‐with‐gene‐flow
Abstract Theory predicts that speciation‐with‐gene‐flow is more likely when the consequences of selection for population divergence transitions from mainly direct effects of selection acting onExpand

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

GENETIC DIVERGENCE ALONG THE SPECIATION CONTINUUM: THE TRANSITION FROM HOST RACE TO SPECIES IN RHAGOLETIS (DIPTERA: TEPHRITIDAE)
Studies of related populations varying in their degrees of reproductive isolation can provide insights into speciation. Here, the transition from partially isolated host races to more fully separatedExpand

Ecological adaptation and reproductive isolation in sympatry: genetic and phenotypic evidence for native host races of Rhagoletis pomonella
Ecological speciation with gene flow may be an important mode of diversification for phytophagous insects. The recent shift of Rhagoletis pomonella from its native host downy hawthorn (CrataegusExpand

Hybridization and the spread of the apple maggot fly, Rhagoletis pomonella (Diptera: Tephritidae), in the northwestern United States
Hybridization may be an important process interjecting variation into insect populations enabling host plant shifts and the origin of new economic pests. Here, we examine whether hybridizationExpand

A test of genomic modularity among life‐history adaptations promoting speciation with gene flow
Speciation with gene flow may require adaptive divergence of multiple traits to generate strong ecologically based reproductive isolation. Extensive negative pleiotropy or physical linkage of genesExpand

Geographic and Ecological Overlap of Parasitoid Wasps Associated with the Rhagoletis pomonella (Diptera: Tephritidae) Species Complex
ABSTRACT One of the fundamental questions in evolutionary ecology seeks to understand how new biodiversity is created and structured into communities. The apple maggot, Rhagoletis pomonella (Walsh)Expand

Parallel Patterns of Morphological and Behavioral Variation among Host-Associated Populations of Two Gall Wasp Species
A powerful approach to address the general factors contributing to ecological speciation is to compare distantly related taxa that inhabit the same selective environments. In this design,Expand

The Geographic Distribution of Rhagoletis pomonella (Diptera: Tephritidae) in the Western United States: Introduced Species or Native Population?
ABSTBACT The apple maggot fly, Rhagoletis pomonella Walsh (Diptera: Tephritidae), is a major pest of commercially grown domesticated apple (Malus domestica Borkhausen) in North America. The shiftExpand
