#Ice worms emerge in pacific northwest glaciers skin#
They have neurotoxins in their skin so birds get sick when they eat them. Banana slug - Banana slug: They're important decomposers, and they crawl around the forest picking up bits of dead pine needles, but of dead wood, eating them, digesting them and recycling those nutrients back into the soil. They spread the spores around the forest and helped increase the health and vigor and extension of these mycorrhizal mets. Northern flying squirrels - Northern flying squirrels: Eat mycromyzal fungi, which they dig up from underground. It eats northern flying squirrels and further spreads the spores of these fungi around the forest. Endangered because of loss of habitat and because of invasion of our forests by barred owls (bigger and more aggressive than the northern spotted owl). Northern spotted owl - Northern spotted owl: its rare. It uses large branches of oldgrowth trees for nesting. They are pooping these Marine derived nutrients into the forest. Marble Murrelet - Marble Murrelet: is an endangered species of sea bird. Laberia oregana releases 5-9 pounds of nitrogen per acre of forest. The nitrogen is then released into the soil and an oldgrowth forest. § As the laberia oregana falls out of the canopy onto the ground. The cyanobacteria, is providing nitrogen, which enhances the growth of the algae.
Lichen is providing a place to grow for the algae.
§ Algae is providing sugar for the lichen. The fungus also eats the algae because it provides sugars. § It takes the nitrogen out of the air and makes it available to the algae which aids the algae in its growth. It's the cyanobacteria that fixes nitrogen. § Labaria aoregana also has a third organism as well, which is a cyanobacteria, which often appears as little yellow dots in the leafy surface of the laberia lichen. O Lichens are a mutualism between a fungus and an alga. Labaria Oregana: - Labaria Oregana: Nitrogen fixing ligan Baby trees like to grow here because the fallen trees are like sponges, they are a nice source of moisture as they soak up moisture in the winter, so in the summer they help the baby trees. Often call rows of trees in the forest that germinate all along the same nurse log: colonnade Seeds will fall onto the trunk of this old tree that's lying on the ground and the seeds will germinate on the trunk of the old tree. Once they fall they become a nurse for new trees. O Fungus rotting out the base of trees and weakening them is the major cause of death for out oldest trees in the pacific northwest. They maybe have died of natural causes, maybe old age or fungus rotting out the base of the trees. Snags Nurse logs - Nurse logs: are large trees that have fallen to the ground. Horizontal diversification - Horizontal diversification: If you draw a line across the top of the canopy it is uneven in height.
