Define antagonistic coevolution and give an example of it.
Antagonistic coevolution: when the effect of an interaction is negative. Examples: Predator & prey, plants & herbivores, Disease

_________ are among the most species-rich families and are renowned for their spectacular floral diversity and intricate adaptations to pollinators.
Orchidaceae
100
The relationship between yucca and yucca moth displayed what type of relationship?
What is mutualism
100
(True or False) Two thirds of orchids reproduce by deception.
False. Only one third.

How many cats does Professor Smith have?
2! >^.^< Meow!

What is the difference between Batesian mimicry and Mullerian mimicry?
Batesian mimicry: harmless species resemble harmful or distasteful species, deriving protection from predators in the process. Mullerian mimicry: multiple unpleasant species resemble each other reinforcing the image

Explain Figure 1 (pg. 490).
Figure 1 represents a comparison of levels of mean genetic differentiation (Gst) among rewarding and deceptive orchid populations. This graph shows that populations of rewarding orchids have higher Gst values than deceptive orchids, which indicates higher gene flow among deceptive orchid populations.

The second burst of yucca moth diversification coincided with what event
Pliocene desertification (arid habitats)
200
What is it called when the pollinaria of many orchid species, only after having been removed from the flower by a visiting pollinator, start to bend downwards shortly thereafter.
Pollinaria bending
200
Where is Wei-Chin from?
Taiwan
300
Name a benefit of cooperative behavior.
Dilution effect, vigilance, defense

This fungus associates with orchids in its early stages.
What is Mycorrhizal fungi
300
Explosive radiation (1st one) of yucca moths occurred no later than ___ MYA.
40

________ is a form of self-pollination, in which a flower is fertilized by pollen from the same flower.
Autogamy
300
What date & time of the EEB390 Final Exam?
December 18th, 10:30-12:30
400
What does game theory attempt to solve for?
Attempts to solve for optimal decisions in strategic situations where others’ choices impact payoff.
400
_________ could increase levels of inbreeding rates if cross-pollination isn't positively impacted by the presence of a reward. Define this term.(*Hint: This term was used in earlier vocab activities from today’s discussion)
Geitonogamous pollination: a form of self-pollination, in which a flower is fertilized by pollen from another flower of the same plant.
400
This article established a molecular clock for the moths based on _______ and used it to estimate the time of major yucca moth life history events.
mtDNA
400
Describe pollination by deception.
pollination strategy in which flowers signal the presence of a food reward to pollinators without providing this reward
400
What day is the EEB390 Final Paper due?
The week of December 2nd.
500
What are the main characteristics of eusociality? Give at least two.
Parental care, overlapping generations, reproductive division of labor
500
What is the difference between the methods orchids use to maximize outcrossing?
Rewarding plants prevent nearby inbreeding with pollinarium bending. Deceptive orchids promote outward pollination by ensuring pollinators move away quickly
500
The second explosive diversification of yucca moths were derived from what type of yuccas?
capsular-fruited yuccas
500
a measure of population differentiation that ranges from zero to one. Low values indicate that little of the variation is proportioned among populations, whereas high values indicate that much of the variation is distributed among populations.
Gst
