Drew Rasmussen Penny Louka Biology 191L December 4, 2010 Lab 14: Community Ecology: Lab Pre Write Up 1. One relationship I observed near bogus basin was a group of Mycena mushrooms growing on a tree. This is an example of commensalism, because the tree is dead, and the mushroom is benefiting by decomposing the tree. Another relationship I observed was birds living in the Douglass Firs up at Bogus Basin. The relationship here is a mutualistic because the birds are able to live in the tree, and the tree is kept clean of different parasites and insects that would eat it. There were many different types of fungi in the forest, and lichens were everywhere. Lichen living on the trees and other plants is an example of a parasitic relationship. The lichens are given a place to live, and can hinder the other plants ability to absorb light, and the fungi can harm the plant or tree the lichens

The fungus’ mycelium forms a relationship called mychorizzae by attaching to the ends of roots and doing many things. The mycelium increases surface area of the roots allowing them to absorb more nutrients, and the fungi also decomposes materials so that the plants can use them for food. In this process the fungus also benefits and gets food. Another parasitic relationship is observed on the gills of different species of fungi. Different insects live in the unshielded gills of the fungi and eat them. This damages the fungi, and provides a food source for the insects....
