EXAM 3 ——SPECIES INTERACTIONS
1.1) Be able to draw out the Interaction Grid and put the right names of species
interactions into each of the boxes. Know the right definitions of all of these
1.2) If you are given a new example of an interaction, you should be able to place it
into one of the categories on the grid (I won’t make them tricky). The best way to
prepare for this is to come up with a lot of examples of interactions that we didn’t
discuss but that would fit into each category.
1.3) What are some examples of highly specialized and highly generalized
predator/prey interactions? Highly specialized and highly generalized mutualisms?
1.4) What is the difference between “specialization” and “obligacy”? To check
whether or not you understand these concepts, you should be able to come up with
at least hypothetical examples of specialized/obligate, specialized/facultative,
generalized/obligate, and generalized/facultative interactions.
1.5) Which is more common: symmetrical or asymmetrical dependency in
interactions? Be able to explain what this question even means (you will want to
draw a picture to be able to do so).
1.6) Imagine that you are studying a mutualism and there is a good “fit” between the
species – for example, a bee is a very effective pollinator, and successfully gets a lot
of nectar out of the flower when it visits. This situation could have been produced by
three processes. What are they? Can you give a real-life example from lecture where
we think that each of these processes has taken place?
1.7) What is invasional meltdown? Give an example from lecture in which this may
be taking place.
1.8) What is coevolution? What are two pieces of evidence that might suggest that
an interaction you are studying is the product of coevolution? Which interactions on
the grid would appear to have NO possibility to coevolve, and why?
