George Washington Carver

Reading about nature is fine, but if a person walks in the woods and listens carefully, he can learn more than what is in books, for they speak with the voice of God.

Science Saturday: Galls, Herring Gulls, and Hairy Cap Moss

(A Gall from our yard...the top of the stem broke...)

A few interesting things:

Galls are an abnormal growth of plant tissue caused by something other than the plant itself. Most commonly caused by insects but they are also caused by mites, nematodes, bacteria, fungi, and viruses.
The Goldenrod Gall is caused by a small fly that lays an egg on the stem of the Common Goldenrod. As it grows it forms a solid spherical gall around itself to protect it and feed it.\
Galls are wonderful for protection, but some birds and rodents can see that they are holding something "yummy" inside, and will eat the contents.
Herring Gulls are one of the most common gull along the Atlantic Coast. They have migrated inland, and have been found by the Great Lakes, the Mississippi and other large bodies of water.
They were protected at the beginning of the 20th century because of low numbers, but since then, they've increased in number and have no need for such protection.
Herring Gulls are ground nesters, so they prefer to be on islands where predators are few. It takes 25-27 days for an egg to hatch. Then the parents feed them regurgitated food until they are old enough to take care of themselves.
Hairy Cap Moss grows in thick spongy beds on the forest floor. It should be called "Mattress moss" because of how soft it is! ;~)
Moss is unique in it's ability to remain dormant for extended periods of time, yet still be alive when it receives water again.
Moss is good for reviving areas that have been devastated by natural causes. Because of their unique ability to adapt, they can revitalize areas stricken by forest fires, floods, volcanoes, and other natural catastrophes!
