Community Ecology
|
group of interacting species
|
|
|
How do interactions affect species diversity? + - interactions?
|
++ = Mutalism
-- = Competition Predator- Prey (+/-) ex. Fox = General pred Specialist Pred = 1 type of prey |
|
|
Food Webs + Chains
|
Drawing of chain of species feeding pyramid
|
|
|
+/- Parasite/Host
|
P use Host to gain energy
ex/ Shistosom ex.2 Snail + human |
|
|
+/- Interaction - parasitoid
|
Eggs planted, Not killing host
egg hatches/ host killed control pest insects |
|
|
+/- Pred/Prey
|
crypsis= hidden/camoflauge
|
|
|
Aposematic?
Mimicry: Batesian? Mullerian? |
Warning colors
ex. Milkweed beetles Frogs Mimicy: ex. Beetle looks like bird droppings Batesian Mimicry: Monarch Bfly (poision milkweed) vs Viceroy (safe) look the same (convergent evolution) Mullarian: several species, learn from eachother |
|
|
Mutualism (+/+)
|
Both benefit species mutually: Yucca/Yucca Moth
|
|
|
Competition (-/-)
|
shared resourse
food nest sites space Seperate Pops grow until they affect eachother Co-occur: 1) competitive exclusion = one species drives out out 2) competitive coexistence = each level off, both able to coexist complete overlap= drives extinct (1) coexistence= partial overalp, yet some unique resources |
