Sympatric speciation in phytophagous insects: moving beyond controversy?

The concept has been intimately tied to entomology since the 1860s, when Benjamin Walsh proposed that many host-specific phytophagous insects originate by shifting and adapting to new host plant species. If true, sympatric speciation would have tremendous implications for o...

Adaptive Dynamics of Speciation: Sexual Populations
