Card Set Information
A comparatively small habitat separated from a major habitat of the same kind.
Theory of Island Biogeography
- The smaller the island, the fewer species
- The farther away the island is from a continent(mainland) the fewer species it will have
Physical and biological changes that occur along the transition between two habitat types.
- Effects survivability of species: temperature difference, exposure to light, etc.
Staggered setting- checkerboard (more edge!!)
Minimal- Block (less edge!!)
Allows migration between parks or preserves- insurance against catastrophe
Steps of scientific method
1. Make observations- develop a question
2. Develop a tentative answer to the question- hypothesis
3. Design a controlled experiment to test the hypothesis
4. Collect data
5. Interpret data through graphs or other means
6. Draw a conclusion from the data
7. Compare conclusion with hypothesis- support or disprove
Manipulated by scientist
Responding variable- depends on independent variable
Exact duplicate of experiment without independent variable
A tentative answer to a question that can be tested and capable of being disproved.
Grand scheme that relates and explains many observations and is supported by a great deal of evidence
Like when you predict something is going to happen- it's like a guess mofo, like a guess
Point source pollution
Pipeline discharge into water (Factories releasing shit into water from a pipe)
runoff from land into water (car wash)
Occurrence of an unwanted change in the environment
-caused by introduction of unwanted materials
-production of harmful conditions (heat, sound, etc.)
Materials(pollutants) that are poisonous to people and other living things
Burning coal in power plants
Compact fluorescent bulbs
Old plumbing systems (lead pipes)
the accumulation or increase in concentration of a substance in living tissue as it moves through a food web.
Hormonally Active Agents
Substances that act like hormones\
Persistent Organic Pollutants
Synthetic organic compounds often containing chlorine, that do not easily break down in the environment.
Heat pollution- Occurs when heat released into water or air produces undesirable effects
- Above 80dB potentially dangerous for humans
-110dB's damage can occur
- Above 140 dB cause pain
Energy of motion (water flowing over a dam, a wheel rolling down a hill)
Stored energy (a car battery, a stretched rubber-band)
Random motion of atoms and molecules- fire, boiling water
Energy of electromagnetic waves
Example- Radio waves, x rays
energy produced through reactions that occur in chemical compounds
Example- Match, fuels such as gas
High quality energy
Easier to do work, more work can be done- cause more change
Lower quality energy
Harder to do work, less work done
First law of Thermodynamics
Energy cannot be created or destroyed- Energy can be converted from one form to another
Second law of Thermodynamics
Energy goes from a higher quality form to a lower quality form
First Law energy efficiency
(Energy delivered/energy supplied) * 100%
Second Law Energy efficiency
The ratio of the minimum amount of work or energy required to perform a task to the amount actually used.
Getting by with less demand for energy.
Yield more energy output from a given amount of input energy
Capture and use waste heat
