Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants

open access: yesAmerican Journal of Botany, EarlyView.

Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...
