8
Population Growth r(reproductive rate) = births-deaths N N = size of population Density Dispersion Define and provide examples
9
Population Growth Biotic potential Carrying capacity Limiting factors Density-dependent Density-independent Define and provide examples
10
Population Growth Age structure Which diagram represents ZPG/decline? Rapid growth vs. slow growth?
11
Population Growth & Regulation Life History Semelparity Iteroparity Survivorship curves Type I = k-strategist (selection) Type II = random Type III = r-strategist (selection) Define and provide examples
12
Survivorship Curves A. B. C. Relative Age Number of survivors
13
Species Interactions Interspecific competition Competitive exclusion principle (Gause) Resource partitioning Character displacement Realized niche vs. fundamental niche Define and provide examples
14
Interspecific Competition Predation True predation Parasitism Parasitoid Herbivory Define and provide examples
15
Interspecific Competition Symbiosis – sym = together, bio=life Mutualism Commensalism (Parasitism Define and provide examples
16
Interspecific Competition Coevolution Morphological defenses Secondary compounds Camouflage Aposematic coloration Mimicry Műllerian Batesian Define and provide examples
17
Community Structure & Growth Ecological Succession Primary Secondary http://www.geo.arizona.edu/Antevs/nats104/00lect20sucn2.gif Describe the changes that occur from left to right in the picture? If the original plot was plowed, is this primary or secondary succession?
18
Biogeochemical Cycles Consist of same basic structure/parts: Major chemicals Reservoir/storage Assimilation (into organisms) Release (from organisms) For each cycle that follows provide an example of the information above.
19
Water cycle Major chemicals ….water (duh!) Reservoir/storage Assimilation (into organisms) Release (from organisms)

25
Phosphorus Cycle Similar to others but does not have an atmospheric component. See pg. 1212 for details.
26
Energy Flow Trophic levels –define and provide examples. Primary Secondary Tertiary/quaternary
27
Ecological Pyramids Energy-Why is a percentage of energy lost as you ascend the pyramid? http://www.mesa.edu.au/friends/seashores/images/energy_pyramid.gif
28
Ecological Pyramids Biomass – Why does the biomass pyramid reflect the same trend as the energy pyramid? http://www.niles-hs.k12.il.us/jacnau/chpt545.jpg
29
Following the Flow Food chains – Create a simple, but specific example. Food webs - Create a simple example using at least 10 organisms.
