Intro./The Anthropocene Flashcards
Precautionary Principle
When you have uncertainty & it raises threats of harm to the environment/human health precautionary measures should be taken even if some cause & effect relationships are not fully established scientifically.
Biodiversity
The variation of life, including genetic & population variation, species variation, & ecosystem, variation
Conservation Biology
The mission is to protect & restore biodiversity, or the diversity of life on Earth. Quick action is critical & the consequences of failure are great.
Scientific Method
A planned, organized approach to solving a problem or answering a question
Scientific Method Steps
- Make Observations
- Ask a Question
- Form a Hypothesis
- Develop Research Questions
- Collect & Analyze Data
- Develop conclusions & Theories
Independent Variable
You can change it
Ex: Lid
Dependent Variable
A factor that can change or respond, if the independent variable has changed
Ex: Flies
Constants
Factors that do not change during an experiment
Ex: Jars and meat
Burden of Proof
The person who made the claim must prove their claim
Model
A simplified representation of some aspect of reality
Darwins Phrase for Evolution
Descent with modification
Charles Darwin Theory
Descent with modification
Ex: Short neck giraffe dies: only long neck giraffes
Natural Selection
- Differentials, or unequal, success in reproduction
- Individuals with higher reproductive success pass on more traits to the next-gen.
- Individual with lower reproductive success pass on fewer traits to the next gen.
Artificial Selection
Humans select desired characteristics
Ex: Dog breeding
Artificial v.s. Natural Selection
Natural selection selects “desired” characteristics
Artificial selection humans make the selection
Resilience
The ability of a species/ecosystem to withstand change
Habitat Loss
The number 1 cause of species loss
Value
Measures of importance
- Preserving the environment
- Paper waste management is good
- Clean streets are good
Ecosystems Services
Any positive benefit that wildlife/ecosystem provides
Ex: There were varmints, and they killed all the predator animals. Then there were mice everywhere. The ecosystem service was the pest-control.
Externality
The side effect of an activity that affects something else or services involved
Carrying Capacity
The population a given space can sustain
Impact
Population+Affluence+Technology
I=PAT
This is a simplification of reality to explain the impacts of the human population
Attitude
An expression or application or beliefs & values (good/bad) to a specific situation
*Littering is bad
