Q

mutualism ex.

A

lichens (algae & fungus)
fungus provides habitat for algea but algea provides food for fungi

16
Q

Aposematic coloration
ex.

A

mimicary

17
Q

Common warning coloration

A

signaling and chemical defense
Aposematic species come to resemble each other

18
Q

coloration leads to

A

Batesian Mimicry

19
Q

Convergent evolution

A

ot become more and more alike

20
Q

Batesian Mimicry

A

palatable or harmless species mimics a harmful model
so predators won’t eat it to show defense

21
Q

Mullerian mimicry

A

two or more poisonous species look like each other

22
Q

why mullerian mimicary

A

group defense?
- predators may evolve innate avoidance

23
Q

Herbivory

A

(+/– interaction)
Plant mechanical and chemical defenses
Adaptations by herbivores

24
Q

Parasitism

A

-Parasite / Host
-Complex life cycles
-Increase in parasites’ fitness so they can make sure they don’t kill the host

25
Q

Mutualism

A

= benefits both species

26
Q

obligate

A

must live together

27
Q

Facultative

A

don’t have to live together but if the do the can benefit from each other

28
Q

Commensalism

A

as far as we know one species benefits and the other is neither harmed nor helped

29
Q

Commensalism is hard to

A

Hard to document in nature
because we dont know how to

30
Q

Facilitation

A

(+/+) or (+/0)
one species comes and makes the enviorment nice for another species that will migrate there but htey will never phiysically interact

31
Q

Coevolution in Community

A

Long term evolutionary adjustments between species

32
Q

Coevolution in Community
types

A

Predator-prey relationships
Parasite-host relationships
Flowers & pollinators
