LECTURE 5 -> COMPETITION Flashcards
interspecific interaction
Competition between species
intraspecific interaction
Competition between individuals of a species
competition
Between 2 or more individuals where one receives a lower rate in survival, fecundity or growth
predation
Consumed a living thing to benefit themselves
grazers
Eat only a portion of the living thing ex//cattle
-> Can benefit the prey, in terms of cutting resulting in more flowers
parasitism
Consumes a portion of the living thing, while the host is still alive -> like the bug in the fish
mutualism
Both species benefit from this interaction
-> facultative mutualism } Helps, but not needed to live (ceader wax-wing and berries)
obligate mutualism} Needed to survive (ex// figs and fig wasps)
interference competition
Directly interfering with the competition, vis hoarding or aggression
exploitation competition
Indirectly -> they explote the same resource
ex//plants for light
apparent competition
ex// a preditor with two prey
-> The population determines which ones are more abundant
realized niche
The range that a species actually lives in, restricted due to competition
Fundamental Niche
The range a species could live in without any interference of competition
competitive exclusion principle
If the ENV is stable, one species will deny other of a resource and trump that species
-> ENV is rarely stable
colonization-competition
In the ant example, One might be better at exploiting resources, but less good at colonizing and spreading the population
-> This population, therefore, lives because it’s really good at colonizing and getting the population up again
trade-off
Where one part of species survival is improved, but another part was traded off for it
