When K1 and K2 are further out, what does the winner depend on?

Front

initial population sizes

Back

Preemption

Front

occurs when an individual prevents other individuals from occupying a location by occupying the space first -passive

Back

Resource competition occurs when individuals compete _____________ by consuming a shared resource.

Front

indirectly

Back

Fundamental niche

Front

complete set of conditions under which an organism can survive and reproduce

Back

Territoriality

Front

establishmnet of an area from which others are partly excluded and is expressed behaviorally (limited to animals)

Back

What does the competition coefficient stand for?

Front

per capita effect of one species on the population growth of another species

Back

When Synedra and Asterionella are placed together why does Synedra do better?

Front

it reduced silica level to where Asterionella cannot use it and it does better at low resource conditions

Back

Allelopathy

Front

between plants and involves production of chemicals that inhibits the growth of another

Back

Character dispacement

Front

competition causes the phenotypes of competing species to evolve to become more different over time

Back

Interference competition occurs when competing individuals ___________ interact to reduce access to resources

Front

directly

Back

Lotka-Volterra equations predict that species can only coexist if _ competition is stronger than __ competition.

Front

intraspecific; interspecific

Back

Best chance for coexistance occurs when K1 and K2 are

Front

both small -self limitation is strong on both species

Back

Is resource competition intraspecific or interspecific?

Front

Gotcha!!!! lol. it is both

Back

Realized niche

Front

subset of fundamental niche describing the conditions under which an organism actually lives given limitations created by interactions with other species

Back

Ghost of competition past

Front

competition acting as an evolutionary force in the past can explain present day phenotypes even if no present day competition exists

Back

What is a niche?

Front

unique ecological role of a species in the environment including what it eats, where it forages, when it forages and what it needs for reproduction

Back

Resource partitioning

Front

The division of environmental resources by coexisting species

Back

Competitive exclusion principle

Front

no two species can coexist in exactly the same niche

Back

Which assumptions are frequently violated in the real world from the Lotka Volterra model?

Front

K and alpha

Back

Types of interference include

Front

-preemption -territoriality -allelopathy
