Abstract
A seed trap for terrestrial plants having dry seeds or fruits is described which holds seeds upon contact and whose trapped seeds are protected to a high degree from loss due to invertebrate predation or wind action. The trap makes use of "Tanglefoot," a sticky non-drying material and is easily constructed, operated, and maintained at minimal cost. The traps are used to determine the pattern of seed deposition around a parent plant. The number of seeds deposited as a function of distance from a mature teasel plant (Dipsacus sylvestris Huds.) exhibit the negative exponential function log y = 2.74−1.69x (r = −0.9731).
