A

This reduces interspecific competition if they have similar niches but if they have some significant differences then they can coexist

Character Displacement

A

Tendency for characteristics to diverge more in a sympatric setting rather than an allopatric setting, because of the sympatric’s increased competition

16
Q

Species Diversity

A

Species richness- the number of different species in the area
Species abundance- The proportion of individuals the species represents

17
Q

Energetic Hypothesis

A

That energy transfer is inneficient, as 10 percent of energy is transferred to the next trophic level

18
Q

Dominant Species

A

The most abundant species in a community, or the species that have the most biomass

19
Q

Keystone Species

A

Not necessarily abundant, but has control over the community structure because of their essential role or niche in the community

20
Q

Foundation Species

A

A species that can dramatically alter their environment on a large scale

21
Q

Immediate Disturbance Hypothesis

A

An even that removes an organisms resources and changes the community. States that moderate levels of disturbance can cause high amounts species diversity

22
Q

Ecological Succession

A

Primary Succession- An ecological succession that begins on a virtually lifeless place with no soil
Secondary Succession- Occurs when an existing community has a disturbance that leaves the soil intact

23
Q

Latitudinal Gradients

A

Measuring how much plant an animal diversity there is in a certain area. Mostly abundant in the tropics
Climate- Energy imput, water availability
Evolutionary Time- More of an opportunity for evolution and speciation because tropics have 5 times more growing season than other regions

24
Q

Island Biogeography

A

The rate aat which species immigrate to an island and the rate at which species become extinct
This is affected by how large the island is and how far away from the coast it is

25
Q

Aposematic Coloration

A

The bright coloration of animals with effective physical or chemical defenses that acts as a warning to predators.

26
Q

Cryptic Coloration

A

Camouflage, making potential prey difficult to spot against its background.

27
Q

Food Chain

A

The pathway along which food is transferred from trophic level to trophic level, beginning with producers.

28
Q

Food Web

A

he elaborate, interconnected feeding relationships in an ecosystem.
