Resistance is a plant's ability to survive a disturbance. Whether
we are considering them adaptations or exaptations either way these
characteristics allow for a plant to survive. Just as we have discussed some
plant’s resistance to fire, others have resistance to flooding and can tolerate
extremely wet conditions.
Resilience is a plant species ability to return to a stable equilibrium
after a disturbance. Though the plant itself may not survive, its future
will. I would compare this to my yard
full of dandelions. Even though I don’t use chemicals, we feed a lot of
dandelions to rabbits. I send my kids out to pick them quite frequently. My
children would be the disturbance. Those dandelions have devised a sneaky trick
to attract my children to them after they have flowered. They entice my
children to spread their future generations of seeds all over the neighborhood
because it is just way to much fun not to blow them apart. The dandelions
always come back. This may not be spot on as far as a good example, but it
helps me to separate the two in my mind.
I think that building and maintaining resistance and
resilience are great concepts to incorporate into natural resources as long as
we are working with native species. My worry would be about adding new species
which could cause state changes after the disturbance instead of maintaining
previous phase changes.
Hi Scott. This was a fun to read post and I love the clever title. This focus on resistance and resilience had me thinking that this would be great to incorporate into urban landscapes too. I was thinking about all the green lawns that have been removed and transformed into some sort of drought tolerant or native landscape in California. If businesses and home landscape designers used this approach we would save water, reduce maintenance, and those within high fire risk zones would benefit greatly.
