Ovipositor morphology and mechanosensory innovation traits favor niche width expansion in Drosophila

Ecological niche breadth is key factor associated with adaptive radiation and speciation.

Ecological niche breadth is key factor associated with adaptive radiation and speciation. For most Drosophila species, the firm surface of intact ripe fruit acts as a physical barrier to oviposition, effectively restricting them to the saprophagous resources. How species…
