Lab 4: Population Dynamics Flashcards
1
Q
Define population
A
A group of individuals from the same species that coexist in space and time
2
Q
What does the BIDE dynamics affect?
A
Size of a population
3
Q
Explain a cohort life table
A
Follow a group of individuals that were born around the same time and track when they die - difficult and overall impossible, so the alternatives are to create an age distribution or record a static life table
4
Q
Explain a static life table
A
Age at time of death is recorded for a individuals that were born at different times
5
Q
How does exponential growth occur?
A
When a population size is too small or there is little to no competition involved
6
Q
How does logistical growth occur?
A
Occurs when there is an upper limit (K/density-dependent factors) to population growth
