Fantastic fungi: Nature’s hidden Helpers
By Katie Eskeldson-Kaiser,
SNCO
When we think of an ecosystem, there are many different
components. We have abiotic
factors such as light, air, water,
and soil, as well as the biotic
factors of living things. These
living organisms are constantly
interacting with each other.
When we look at these interactions, it helps to group
them based on who benefits,
who has a negative effect, or
if there is any effect at all. The
most common interactions that
come to mind are instances like
predation where one animal
eats another, or competition
when two animals compete
over food or another resource.
Not all interactions result
in one participant, or both,
experiencing a negative effect.
Mutualisms are interactions
where both participants receive
benefits. The most common
example we learn about is with
pollinators. A bee will visit a
flower and receive nectar, while
the plant is able to pollinate and
produce fruit and seeds.
One organism that often
goes unnoticed is fungi. When
we think of fungi we often
think of the fruiting bodies or
the mushrooms. The mushroom is only one small portion
of the fungi, just like an apple
is only one small piece of a tree.
The bulk of the fungi is the
many thread-like hyphae that
make up the mycelium. Mycorrhizal fungi colonize plant
roots to exchange resources,
creating a mutually beneficial
relationship. The plant provides carbohydrates and sugars
while the fungi break down
complex organic matter to
supply nitrogen, phosphorus,
and other trace elements into
the soil for the plant. Together,
the fungi and plant help each
other, but there is much more
to this partnership.
This partnership doesn’t
just benefit one tree. Instead,
scientists have found that trees
use these mycorrhizal fungi to
create a network for communication and resource sharing
among related trees. Douglas-
fir trees can recognize the root
tips of their relatives and send
more carbon and nutrients
through the fungal network.
This allows the “mother trees,”
the older more established trees,
to pass water and nutrients to
struggling saplings that send
out distress signals through the
mycorrhizal network.
How does this network benefit the fungi? The fungi enact a
“toll” for their network services
where they keep about 30% of
the sugar that the connected
trees generate. Though the
“toll” is high, the benefit for the
trees far outweighs the costs.
The partnership between a
plant and mycorrhizal fungi
has long been known to benefit
individual plants, but scientists
are discovering that the diversity of these partnerships also
affects competition among
different plant species. The
types of fungi present can cause
one plant to win and another
to lose, but they can allow for
peaceful coexistence between
fierce competitors. With the
right combination of fungi,
they can alter the amount and
source of soil nutrients each
plant uses. These changes create
niche differentiation, or slightly
different mini habitats, that allow the plants to coexist instead
of competing.
These fantastic fungi can act
as delivery services, communication networks, peacemakers
and resource suppliers. They
allow forests to thrive, trees to
help one another, and perhaps
much more as scientists continue to study all these amazing
interactions.
So next time you are walking
in the woods, and you spot
a mushroom, look at all the
plants around it and think of
all the interactions that might
be taking place.
