a group of individuals of the same species existing together at the same time and location
interactions with local populations of different species more common than other populations of same species
difficulty defining
no clear boundaries
movement is common
characteristics
birth rate
death rate
age structure
sex ratio
density
distribution
connectivity
reproductive mode
continuum of organization
ecosystem
community
species
lineage
population
genome
gene
base pair
humans and population dynamics
all populations interact
humans have increased in density
use too many resources
better hygiene, nutrition, medicine, technology, agriculture, education, technology, industry, global agriculture
increased interactions
more extinctions of species
population momentum
populations continue increasing even when birth rate stabilizes
older generation takes time to die
