  • Large leaves in warm, moist environments confer an advantage in seedling light interception efficiency.

    Lusk, Christopher H.; Grierson, Ella R.P.; Laughlin, Daniel C. (2019)
    Leaf size varies conspicuously along environmental gradients. Small leaves help plants cope with drought and frost, because of the effect of leaf size on boundary layer conductance; it is less clear what advantage large ...

    Welikala, Dharshika; Lehto, Niklas; Hartland, Adam; Robinson, Brett (2019)
