Chapter 3 Flashcards
A Group of Organisms in the same area is known as?
Population
In a Population where each individual is distant genetically this is known as?
Unitary
In a Population where each individual is a Clone is known as?
Modular
Subpopulations that are connected together via migration are known as?
Metapopulations
What are two ways we measure populations?
Crude and Ecological Density
When you measure the numbers of species of interest in the same area is known as?
Relative Densities
What is a Positive to using Relative Densities to measure a Population?
Cheaper than Population Estimate
What is a Negative to using a Relative Densities to measure a Population?
Hard to get conditions the same year after year as animals migrate and it’s hard to get the actual population estimate
What are the 3 types of Dispersion patterns?
Random, Uniform and Clumped
When the Dispersion Pattern has NO Interactions it is considered?
Random
When the Dispersion Pattern has Even Spacing it is considered?
Uniform
When the Dispersion pattern has Scattered Groups it is considered?
Clumped
What are the two types of Dispersal Patterns?
Passive and Active
Seeds being spread by the wind is considered what type of Dispersal Movement?
Passive
What is it called when you have migration but return to your origin?
Migratory Movements
When you move from Freshwater to Saltwater to reproduce is it called Anadromous or Catadromous?
Catadromous
When you move from Saltwater to Freshwater to reproduce is it called Anadromous or Catadromous?
Anadromous
Is a Home range defended?
No
What is a Pro of GPS transmitters on endangered animals?
You can know there location at all times and have current updates
What is a Con of GPS transmitters on endangered animals? (2)
Poachers can hack the GPS and it can easily fall off
Are Territories Defended?
Yes
The Bigger the organism the Longer of Shortere the Lifespan?
Longer
What Small Animal has a Long Lifespan?
Amphibians
How do you get Crude Density?
Total Population Size/Total Area
What is Ecological Density?
Individuals collected in a habitable area only but not in the whole area
What are the two methods used to estimate a population?
Lincoln Peterson and Jolly-Seber Method
What does the Lincoln Peterson use to estimate a population?
Using one marking and one re-capturing event
What does the Jolly-Seber Method use to estimate a population?
Can handle any number of mark and re-capture events
What are Relative Densities?
Number of Species of Interest in an area over time
What are the Two Test we use to look at Dispersion Patterns?
Chi-Square and F-Test
The Chi-Square Test looks for what types of Dispersion Patterens?
Clumped, Uniform and Random
Which Test is Preferred when finding out the type of dispersion pattern?
The F-Test, also known as the Mean and Variance Test
In the Mean and Variance Test (F-Test), if the Variance is Greater than the Mean, what type of Dispersion Pattern is it?
Clumped
In the Mean and Variance Test (F-Test), if the Variance is Less than the Mean, what type of Dispersion Pattern is it?
Uniform
In the Mean and Variance Test (F-Test), if the Variance is the same as the Mean, what type of Dispersion Pattern is it?
Random
What type of Migratory Movement is it when an animal leaves and returns to their point of origin daily?
Repeated Movement
What is it called when an animal migrates and returns to its origin once a year?
Annual Repeated Movements
What type of Migrations are Anadromous and Catadromous movements?
One-time Migrations
