niche partitioning

Front

change in location or breadth as a result of competition

Back

"ghost of competition past"

Front

species competed in the past and utilization curves shifted, so species don't compete currently

Back

interference competition

Front

one species excludes other species from a resource through direct aggression

Back

why is intraspecific competition more intense than interspecific competition?

Front

because individuals are competing for the same set of resources

Back

niche

Front

functional role in a community

Back

what is the best way to document competition?

Front

competitive release

Back

intraspecific competition

Front

competition between individuals of the same species

Back

competition

Front

active demand for resources in short supply

Back

competitive release

Front

removal of one species allows expansion of the other's range

Back

ways to document competition

Front

- niche partitioning - competitive release - character displacement

Back

independent evolution

Front

species could have evolved independently and secondarily came together

Back

outcomes of competition

Front

- exclusion - niche partitioning

Back

character displacement

Front

Species evolve non-overlapping traits to avoid competition; 2 species have to exist in allopatry and sympatry

Back

_____ competition takes time to exclude a species, while _____ competition excludes a species very quickly

Front

exploitative; interference

Back

explanations for niche partitioning

Front

- "ghost of competition past" - independent evolution - behavioral shift due to current competition

Back

exploitative competition

Front

species that is better at consuming a resource will have a disproportionately high share of the resource; indirect interaction through the resource
