zero growth isoclines

Front

equilibrium solutions can be demonstrated graphically as ...

Back

amensalism (-,0)

Front

a special form of competition (-,-) -asymmetric or one-sided competition -all competition lies somewhere between completely equal and completely one-sided

Back

allelopathy

Front

when one plant releases toxins to harm the competing plant

Back

What organisms compete for

Front

-resources (food, water, light) -space -mates

Back

resource partitioning

Front

-using the same resources but in slightly different ways to avoid complete competitive overlap -this method allows very similar species to coexist by way of resource partitioning

Back

Exploitation competition (indirect)

Front

occurs when one competitor uses resources and in so doing, reduces the resource availability to the other competitor -most common form of competition in all organisms

Back

Intraspecific competition

Front

competition between individuals of the same species -leads to the density-dependent logistic growth curve seen in the study of population ecology

Back

interference competition (direct)

Front

competition that occurs when two competitors physically challenge or harm each other to obtain a resource -reasonably common in animals -also seen in plants when one plant releases toxins to harm the competing plant

Back

redefinition of the competitive exclusion principle

Front

two species cannot occupy the exact same niche within a community

Back

Guilds

Front

-consist of different species that acquire nutrition in the same way -competition will occur between members the same guild

Back

Niche

Front

-when, where, and how a species makes its living -all of the environmental factors necessary for a species' existence (its survival, growth, and reproduction) -a species' role in its environment -an N-dimensional hypervolume

Back

interspecific competition

Front

competition between individuals of different species

Back

isoclines

Front

show equilibrium sizes for one species in combination with different numbers of individuals of the other species -can be used to determine the conditions under which each species will increase or decrease in size

Back

Competitive exclusion principle (1934)

Front

two species cannot coexist in a community if they use the same resources in the exact same way -one species will persists, while the other will be outcompeted and driven to local extinction

Back
