population ecology

Question 1

What is per capita population growth rate?

Answer 1

• the rate at which the population size changes per individual in the population
• This growth rate is determined by the birth, death, emigration, and migration rates in the population

Question 2

Differentiate exponential and logistic growth.**

Answer 2

• exponential: presumes infinite resources, resulting in unrestrained population expansion.
• logistic: considers resource limitations and a carrying capacity (K) - the maximum sustainable population.

Question 3

What is a population-regulating factor?

Answer 3

• any parameter (intra or extra) that prevents a population from growing exponetially
• ex. lack of mates, disease, lack of food

Question 4

What are meta-population dynamics? Why are meta-population dynamics closely linked to human interactions with other species?*****

Answer 4

• interaction of a population thrugh time and space
• different sub populatons that move around (immigrate and emmigrate) to different habitats/spaces
• they are changng spatial, SPATIAL
• additions parameteres (rates): immigration and emmigration
• a metapopulation is made up of small, isolate populations
• although some subpopulations go extinct iver time, migration can resore os establish subpopulatons
• realted to humans because humans immigarte and emmigrate. humans can take advantage of spaces that have been abondoned by other species

Question 5

what is ecology

Answer 5

• the science of interactions
• study of species spcies and species environment interactions
• how to species percieve their environment and thus how do they make decisions?
• everything in ecology is SCALE dependant

Question 6

questions in ecology

Answer 6

• structural: who/what is there (age, gender, competition, diversity, etc)
• dynamical (how does that change through time and/or space)

Question 7

perspectives in ecology

Answer 7

• physiologial
• POPULATION
• COMMUNITY
• landscape
• ecosystem
• evolutionary
• these are base on and ask structal and dynamical questions

Question 8

what is population ecology

Answer 8

individuals of the same species interacting at the same spatial and temporal scale

Question 9

How can you mathematically model ecological populations? Why is this useful?***
