| 1. Commoner's laws of ecology |
a.
"Everything is connected to
everything else"
b. "Everything must go somewhere"
c. "Nature knows best"
d. "There is no such thing as a free lunch" |
| 2. Energy primer |
a. Definition

c. Types of energy |
| 3. Evolution |
a.
Natural selection
b. Environmental adaptations and ecological
niche
c. Speciation, biodiversity, co-evolution,
extinction
d. Rates of evolution - gradualism vs.
punctuated equilibrium |
| 4. Organismal ecology |
a.
Unit of natural selection –
survival and
reproduction
b. Kingdoms of life and requirements for life
c. Habitat, environmental adaptations, and
ecological niche
d. Homeostasis and feedback regulation –
thermoregulation, osmoregulation, gas
exchange, energetics
e. Cellular metabolism – photosynthesis,
cellular respiration,
chemosynthesis
|
| 5.
Population ecology |
a. Population dynamics – exponential vs.
logistic growth
b. Carrying capacity and limiting factors
c. Population structure –
age, gender,
survivorship
d. Population genetics and genetic diversity |
| 6. Community ecology |
a.
Species interactions – resource
competition, predation,
symbiosis
b. Competitive exclusion principle
c. Niche partitioning and keystone species
d. Species biodiversity
e. Ecological succession – primary vs.
secondary
f. Disturbance |
| 7. Ecosystem ecology |
a.
Matter/Biogeochemical cycles
(biotic/abiotic) – water,
carbon, nitrogen,
phosphorous, sulfur
b. Energy flow – trophic levels, food
pyramids, food webs
c. Thermodynamics – 1st law (conservation
of energy) and 2nd law
(entropy)
d. Biomes – environmental factors influencing
distribution
e. Value of ecosystem services |
| 8.
Biosphere ecology |
a. Global energy flow – solar input,
ocean
currents, air mass circulation
b. Global matter cycling – global
biogeochemical cycles
c. Global biodiversity – species distribution
and abundance
d. Plate tectonics – theory of continental drift
e. Global environmental issues – extinction
crisis, climate
change, etc. |

This video (narrated by Edward Norton) shows how
important the "big bad wolf" and other predators are to
ecosystems. Follow the video with an essay assignment where the
students write about "Why are predators important?" They must
use examples from the video on what can go wrong without
predators and suggest ideas of what we can do to try and fix the
problems we have. |
