TOPIC
PAGES
430-437
Intro to Ecology
- individual organism, population, community, ecosystem, species, habitat, range,
niche, succession, biosphere, biomes
440-443
Trophic Structure of Ecosystems
- producers, consumers, decomposers, food webs and chains
444-449
Energy Flows
- uses of solar radiation, primary productivity, biomass, productivity pyramids +
Rule of 10, uses of energy by organism, pyramid of numbers, biomagnification
Predator-Prey Lab
466-472
Characteristics of a Population
- demography, density, dispersion patterns, census, sampling methods, transects,
mark + recapture and estimates of population size
473-479
Population Growth
- growth factors, actual births vs birth rate, actual deaths vs death rate, change in
population size vs population growth rate, exponential growth, logistic growth vs
sinusoidal growth, overlapping generations and non-overlapping generations,
ALL FORMULAS, carrying capacity
Population Lab
481-491
Population Growth Factors
- density independent (abiotic), density dependent (biotic), interspecific (chart p
488) competition (including predator and prey interactions, parasitism,
commensalisms, mutualism) as well as intraspecific competition
492-498
Life history
- types I, II and III survivorship patterns, other features like fecundity, age
effects, mortality, life tables, age structure and pyramid, opportunistic (r-selected)
vs equilibrial (K-selected) life histories
504-511
Human Demography
- graph and key factors in the growth of the Human Population, fertility rate(#
children born alive), replacement rate, urbanization effects
