What abiotic factors impact global patterns of animal distribution?
ANSWER ✔✔ Temperature and Water.
What is the three-cell model and how can you predict the latitude biome position?
ANSWER ✔✔ The Tricellular Model is a simplified explanation of how atmospheric
circulation patterns create distinct weather and climatic conditions at various latitudes. It
is based on the differential heating of the Earth's surface.
Define population density.
ANSWER ✔✔ The average number of people living in a square mile or square
kilometer.
What variables go into a life table?
ANSWER ✔✔ A life table shows, for each age, the probability that an individual will die
before their next birthday, as well as the probability of surviving any particular year of
age.
What are the 3 different survivorship curves? Provide examples of organisms for each
type.
ANSWER ✔✔
Type I - Most individuals survive to old age (e.g., humans).
, Type II - Survivorship is constant over lifespan (e.g., some birds).
Type III - Low survivorship at early age (e.g., oysters).
How can species interactions be defined based on their effects on populations? Name and
identify the + or - interactions.
ANSWER ✔✔
Mutualism: +/+
Competition: -/-
Predation, herbivory, parasitism: +/-
Commensalism: +/0
Amensalism: -/0
Explain the patterns of species richness and how they vary.
ANSWER ✔✔ Species richness and composition vary with latitude; lower latitudes have
more and different species than higher latitudes. Species richness also varies by
continent, with the same biome differing depending on location.
How do you calculate species diversity?
ANSWER ✔✔ Calculate the proportion (pi) of each species by dividing the number of
individuals of that species by the total individuals in the community. Multiply the
proportion by the logarithm of the proportion for each species.
What is the process called when a system tries to reset itself after disturbances? Distinguish
between primary and secondary succession.
ANSWER ✔✔
Ecological succession.
Primary succession starts in lifeless areas with no soil, such as after a glacier retreat or
lava flow.
Explain feeding relationships among species in a community and how they impact each
other. How are these represented?
