Widespread genomic divergence during sympatric speciation
Speciation with gene flow is expected to generate a heterogeneous pattern of genomic differentiation. The few genes under or physically linked to loci experiencing strong disruptive selection canExpand
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
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
ADAPTIVE CHROMOSOMAL DIVERGENCE DRIVEN BY MIXED GEOGRAPHIC MODE OF EVOLUTION
Chromosomal inversions are ubiquitous in nature and of great significance for understanding adaptation and speciation. Inversions were the first markers used to investigate the genetic structure ofExpand
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
Insights from community ecology into the role of enemy release in causing invasion success: the importance of native enemy effects
The enemy release hypothesis (ERH) predicts that the success of invasive species is caused by reduced enemy pressure in species’ introduced ranges. The ERH is a highly-cited explanation for invasionExpand
The diapause response of Rhagoletis pomonella to varying environmental conditions and its significance for geographic and host plant‐related adaptation
The recent shift of Rhagoletis pomonella Walsh (Diptera: Tephritidae) from its ancestral host hawthorn to apple is a model for incipient sympatric speciation in action. Previous studies have shownExpand
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
