-/0 interaction
one species harmed, other unaffected
Back
fundamental niche
Front
all resources species is capable of using w/ abiotic requirements
Back
interference competition
Front
direct competition
hurt competitor's ability to use resource (attack another predator, plant shades out other)
competitor prevents other from accessing/using resource
Back
parasitism (competition)
Front
+/-
parasites positive benefit, hosts negative
Back
allelopathy
Front
interference competition in plants, toxins harm other species
Back
asymmetrical competition
Front
uneven competition
cant reach full carrying capacity bc lost resources to previous competition
competition hurts even dominant competitor!
Back
competitive exclusion
Front
local extinction of species due to dominant species preventing other from using resource
asymmetrical competition
Back
character displacement
Front
competition causes phenotype of competing species to evolve differently over time
Back
interspecific competition
Front
competition between members of different species
Back
resource partioning
Front
use limited resource in different ways
promotes coexistence
Back
competition
Front
non-trophic (same level) interaction in which individuals are harmed by shared use of limiting resource
leads to difference in resource partitioning (character displacement in same species)
Back
competitive exclusion principle
Front
2 species that use resource in same way cannot coexist
Back
exploitative competition
Front
indirect competition
compete for limited resources
reduce supply of resource as used (watering hole)
Back
intrasecific competition
Front
competition between indivituals of same species
Back
competitive coexistence
Front
share limited resource, but survive together
Back
realized niche
Front
actual niche of a species
limited by species interactions (biotic)
Back
fugitive species
Front
disperse from one place to another to take advantage of distrubances (avoid competition)
