Blog Post #5: Fungi Field Trip Makeup
·
Photo, name, and
description of location that you visited
I
went to Martha Lake Park within the Lynnwood area. It is a lakefront park which
has playgrounds, fishing docks, picnic areas and boardwalks through wetlands.
As you get closer to the water the ground becomes muddier. The park contains
many trees and bushes.

Description and
identification (your best guess) of each of the 3 organisms
·
Figure 1: moss and
lichen found on decaying tree stump. Possibly Flavoparmelia caperata, Flavopunctelia
soredica, and Dicranella heteromalla
·
Figure 2: Moss found
on tree trunk of living tree. Possibly Hair cap moss
Lichen
thrive in sites where nothing else grows. They can grow on rocks, barren soil
and the bark of dead or live trees. Lichen are not parasitic when they grow on
trees. Lichen are able to do nitrogen fixation. Lichen are indicators of a
trees age.
Moss
are photoautotrophs that photosynthesizes and reduces CO2 in the
environment. Moss is able to protect the surface of the ground by provide a
cushion during sever weather which reduces soil erosion. The disappearance of
mosses can be considered bioindicators for the level of pollution in the
environment.
Figure 3: Heron
Herons live near sources of water,
including rivers, lake edges, marshes, saltwater seacoasts, and swamps. They require
tall trees near water to nest in. Herons eat a wide variety of small prey,
mainly fish and insects. Herons control fish and insect populations in many
different habitats. They are also an importance source of food for the animals
that prey on them.
Figure 4: Ducks and water lilies
Ducks are normally found in places
with water, like pons, streams, lakes, and rivers. Ducks are omnivores, they
tend to feed on fruits, seeds, plants, insects and fish
.
Water lilies are found in freshwater
lakes, ponds, and other shallow-water habitats. It photosynthesizes by floating
its leaves upon the waters surface and reduces CO2 from the
environment. However water lilies are less abundant than moss/lichen due to the
specific conditions it must have to grow.
Questions:
·
Did you learn something
about fungi or plants that surprised you?
- Something I learned that
interested me was that lichen are an indicator of
·
Reflection:
What was something that you observed on the fungi field trip? What was
something you learned?
- I observed that moss can be specific about the species of tree they grow on. There were a lot of tree growing next to each other however even though they were in the same location and near water, some trees grew moss while some trees next to it didn't.

Write at
least 3 scientific questions based on your observation.
- Why
did some trees grow moss/lichen and others didn’t, even though they were
near water?
- How accurate is it to use
lichen to predict the age of a tree? Don’t individual lichen of the same
species grow at different rates?
- Is the side of the stump in
Figure 1 brown rot, from fungi chewing through the tree’s dead wood?

Write 1
hypothesis based on the questions above.
If the stump is decaying by brown rot fungi it will
typically be brown in color and the decay will look crumbly, chipped and
blocky.
Interesting that some trees were covered with moss and some were not. Did you notice anything else different about the trees that might indicate why moss grow on some trees but not others?
