Internet research:
This is a type of an oak tree.
It disperses by dropping acorns, which then get moved by other organisms,
It is found in temperate zones, generally to the north (www.about-oak-trees.com/index2.htm),
They reproduce by flowering and having pollinators come through and pollinate. Once pollinated the acorns drop and can be broken by algae to release its seed which then can grow into a tree (www.newton.dep.anl.gov/askasci/bio99/bio99643.htm),
Once an oak tree is fully mature it can produce over 2000 acorns a year (ejad.best.vwh.net/java/population/facts_oaks.html),
It does not have any special adaptions besides the acorn to protect the seed.
Observation:
I would say I am looking at a single population. Because the oak is so big and it has its unique seed dispersal the population is over quite a large area. It's nearest mating members are in the lot I looked at as well as members in the lots next door which you can see. It is a pretty random distribution, some are closer to each other than others, and some are spread extremely far apart. This tree seemed to be located where there was soil on one side of it where just grasses were growing on it. When venturing off the trails a great distance I never found any, they were all located right off the trail, maybe so there was nutrients in the soils that were not being taken by other trees. I believe that it is a source because it is giving off oxygen into the environment and does not seem to take up a lot of nitrogen or phosphates since none are found in highly dense areas. The offspring probably would go on the lot, in the meadows, where my family has to chop them down every year, or into neighboring yards. Immigrants can come from down the river then get picked up by a bird and dropped onto our land.
Math Stuff:
Literature:
R.B. Miller/1923/ White Oaks- In this experiment Miller was studying the age dynamics of the oak trees. He determined that there were a lot less old trees than young ones in Illinios. He did not specify why, but in the case of the ones I am looking at, It is probably because the old ones can get to be too big and get in the ways of the power lines, or there is just simply not enough nutrients where we are forcing them to grow to sustain larger and older trees.
In the Weevil expirement from our podcast in week 4 angel.msu.edu/section/content/default.asp?WCI=pgDisplay&a...
It talked about introducing the weevils to eat the mile a minute weed., however the weevils also eat the acorns of the oak trees preventing less seeds from dispersing which is an example of disadvantages of invasive species. (www.fs.fed.us/r8/foresthealth/pubs/oakpests/p35.html)
Only part of this is fungus. Lichens consist of a symbiotic association of algae (usually green) or cyanobacteria, and fungi. I nevertheless include them in this set of fungus images.

Advice to visitors to Birnie and Gaddon Loch to beware of algae in the water. Likely to cause sudden tummy pain if drunk. ooops.

This summer's humidity has allowed the most primitive algae to colonize anything offering the least bit of sustenance, like a vertical concrete wall beneath a drainspout. Life endures.
(And you wonder why I think extremophiles are normal, on and off Earth.)

Fish suffocate, Algae is washed up on the beach. Many lakes are over fertilized by runoff from humanity''s excessive waste and short term thinking. The deplorable beat moves on. What will our great grandchildren think? For more on "world awareness" thinking visit onenessbecomesus.com

Lost my algae eater a few weeks ago and my tank is getting full of algae so went to Petco to get another one and they only had one left. When I brought him home I noticed it looks like he had an owy. He didn't make it more than 24 hours so going back to get a refund.
