Our next contest is Seed Dispersal. Please compete with images that highlight mechanisms of seed dispersal. For example, you could submit pictures illustrating a particular adaptation that aids in seed dispersal (e.g., wings for wind dispersal, barbs that stick to fur or feathers, fleshy fruits that attract certain frugivores as dispersal vectors), or you could post pictures of animals caught in the act of dispersing seeds. Select one (1) of your best images to compete with. Submissions will be open through next Monday.

Contest rules and instructions on voting and posting are all located here . Please read the rules thoroughly before beginning.

Remember to post below only images and their number in the posting sequence, along with a brief explanation of how the image relates to the contest topic (optional). Also, make sure your image is properly tagged, licensed, and posted to the EOL group. If you have questions or comments post them to this thread. Thanks!

#5 White-winged Dove on Saguaro fruit, Arizona. You can see some of the tiny black seeds stuck to the bird's bill, and many more will be in its gut, waiting to be dropped far away from the 15-metre tall mother cactus.

#6 Common Winterberry. Here is a typical bird-dispersal syndrome: seeds are presented in small, brightly colored berries that have a succulent pulp. Yum says the robin.

#7 Maple seed pods / samara (aka "helicopter"). Carried by the wind, they helicopter down to the ground, hence the nickname. As kids we used to peel these open, remove the seeds, and stick the pods on our noses. Here photographed on my dog's paws. Not the normal means of conveyance!

#11 Draba boerhaavii: Wind is responsible of dispersal of its seeds: they don't look like it in this photo here but they're tiny enough go get spread far and wide by wind only.

Xanthium sp. seed pods, being spread by an American plains bison, Bison bison bison. The seeds are contained in a spiny case called a bur or cocklebur. The spines then hook into the fur (or clothing) of passing mammals and eventually get deposited elsewhere.

Some parasites are known to modify the behaviour of their victims for their own profit. Flies parasitized by certain entomopathogenic fungi attach themselves firmly to a stem or other high place before they die. In this way, the spores of the fungi are efficiently dispersed.

#4 again. It is still a great photo.

Apparently if I try to leave a comment with just "#4", as my last one, it won't post it and instead jumps me up to my previous comment. One must add something to their new comment if their vote remains unchanged, or it won't post.
