Climate Change
Greenhouse gases absorb this type of radiation.
Salinity, light levels, current/waves, and levels of essential nutrients are an example of this.
What are abiotic factors that determine types and numbers of marine organisms?
This is the largest terrestrial carbon sink.
What is terrestrial vegetation?
BAll individuals of a given species that live and reproduce in a particular place.
What is a population? (note: place is not really defined here!)
This principle states that complete competitors cannot coexist.
What is the competitive exclusion principle?
This greenhouse gas has the largest impact on the environment.
What is carbon dioxide?
The marine life zone when sunlight is able to penetrate.
What is the photic zone?
This is where the largest carbon pool can be found.
What is the ocean?
We classify distributions with three dispersion patterns.
What are random, clumped, and uniform? (extra points if you can give examples of each...10 seconds!)
This what the abiotic and biotic factors will permit a species to exist.
What is a realize niche?
“The change in average net radiation at the top of the troposphere which occurs because of a change in the concentration of a greenhouse gas or because of some other change in the overall climate system.” (Houghton 2004)
What is radiative forcing?
Ocean acidification is primarily driven by this.
What is the release of H+ as Carbonic acid is converted to Bicarbonate?
Long term carbon storage occurs via this in both the terrestrial and marine carbon cycles.
What is sedimentation?
These equations are used to predict population growth. Please write the equations on the board for the class.
What are the exponential and logistic growth equations?
This hypothesis states that nutrients are seldom limiting and that herbivore are strong regulators of plant populations.
What is the Green World Hypothesis? (Top-down control would also work here)
The increase in CO2 accounts for around this percentage of the enhanced greenhouse effect.
What is 70%?
The combination of these two factors will have the largest impact on ocean community and ecosystem dynamics.
What is temperature and ocean acidification?
These two factors drive the location of the world's major terrestrial biomes
What are annual temperature and precipitation rates? (bonus points if you can name 2 factors that drive temperature and precipitation rates....you have 10 seconds)
These are the 3 assumptions of the mark-recapture method.
What are no change in population size, marked and unmarked individuals are captured with equal probability, and marked individuals mix uniformly and randomly after release.
This scientist proposed that ecological succession in plant communities occurs in a definite order.
Who is Clements?
The changing of the timing of seasonal activities of animals and plants due to climate change.
What is phenological shifts?
Nutrient inputs in excess of what the system normally processes, runaway photoplankton growth and reproduction, bacterial consumption of dead photoplankton, and metabolic consumption of oxygen of bacteria are all factors that lead to this.
What is the formation of marine "dead zones"?
(this question is reversed) In the Drake et al. (2011) study, why does the elevated carbon content in the organic horizon not translate into the mineral soil?
1. Higher root production leads to higher root respiration.
2. Phenolic content is lower in the CO2 plots, which leads to increased DON mineralization by bacteria.
This is the point where a population in logistic growth are increasing the fastest.
What is half of the carrying capacity (K)?
We are losing this number of species to extinction per year.
What is 50,000?
