title: A genetic model for sympatric speciation through habitat diversification and seasonal isolation.
abstract: Based on studies with natural populations, we offer a genetic model for sympatric speciation that could have broad application to polyphagous animals with habitat differences. The model comprises three steps, each of which includes simple genetic changes and plausible selective forces.
