Intrinsic reproductive isolation between Trinidadian populations of the guppy, Poecilia reticulata.

abstract：:Decoupling between floral and leaf traits is expected in plants with specialized pollination systems to assure a precise flower-pollinator fit, irrespective of leaf variation associated with environmental heterogeneity (functional modularity). Nonetheless, developmental interactions among floral traits also decouple f...
