lec 12- competition cont. Flashcards
what are the special cases of competition?
asymmetric competition- competition between species are not equal
context dependent competition- changes in biotic and abiotic environments result in change in competition
what is a community?
a group of species living together in one area
what are assemblages?
taxonomically relates species populations that occur in one community
what are the two types of communities?
holistic- a community where the species within it are interdependent, rely on one another to maintain balance in the ecosystem (closed)
individualistic- species in a community that live independent of one another, can tolerate the local physiological and biological conditions (open)
what are ecostones?
a steep transition between two biological communities
how do you design a study to test if two species are competing and what are the response variables?
compare their diet compositions with one another, and then see it when there are both, one of each, and none
Response variables: population size, population growth, individual growth, reproductive output
