Mader 47 Vocabulary

Front 1

Method of hiding from predators in which the organism's behavior, form, and pattern of coloration allow it to blend into the background and prevent detection.

Back 1

camouflage

Front 2

Tendency for characteristics to be more divergent when similar species belong to the same community than when they are isolated from one another.

Back 2

character displacement

Front 3

In ecology, community that results when succession has come to an end.

Back 3

climax community

Front 4

Joint evolution in which one species exerts selective pressure on the other species.

Back 4

coevolution

Front 5

Symbiotic relationship in which one species is benefited, and the other is neither harmed nor benefited.

Back 5

commensalism

Front 6

Assemblage of populations interacting with one another within the same environment.

Back 6

community

Front 7

A community is said to be stable when it can persist through time, resist changes, and recover after a disturbance.

Back 7

community stability

Front 8

Theory that no two species can occupy the same niche.

Back 8

competitive exclusion principle

Front 9

Coloration of an animal that helps it to concel itself in its surroundings

Back 9

cryptic coloration

Front 10

Role an organism plays in its community, including its habitat and its interactions with other organisms.

Back 10

ecological niche

Front 11

The gradual replacement of communities in an area following a disturbance (secondary succession) or the creation of new soil (primary succession)

Back 11

ecological succession

Front 12

Species that have a broad range of niches, such as diversified diet, wide range of environmental tolerances, and diverse habitat (e.g., racoons, roaches, and humans).

Back 12

generalist species

Front 13

Place where an organism lives and is able to survive and reproduce.

Back 13

habitat

Front 14

Organism that provides nourishment and / or shelter for a parasite.

Back 14

host

Front 15

Similar species trying to occupy the same niche in an ecosystem compete with one another for a share of resources, and in this way the number of niches increases.

Back 15

interspecific competition

Front 16

Species whose activities significantly affect community structure.

Back 16

keystone species

Front 17

Superficial resemblance of two or more species; a mechanism that avoids predation by appearing to be noxious.

Back 17

mimicry

Front 18

Symbiotic relationship in which both species benefit in terms of growth and reproduction.

Back 18

mutualism

Front 19

Species that is dependent on a host species for survival, usually to the detriment of the host species.

Back 19

parasite

Front 20

Symbiotic relationship in which one species (the parasite) benefits in terms of growth and reproduction to the detriment of the other species (the host)

Back 20

parasitism

Front 21

Early colonizer of barren or disturbed habitats that usually has rapid growth and a high dispersal rate.

Back 21

pioneer species

Front 22

Interaction in which one organism (the predator) uses another (the prey) as a food source.

Back 22

predation

Front 23

Organism that practices predation.

Back 23

predator

Front 24

Organism that provides nourishment for a predator.

Mechanism that increases the number of niches by apportioning the supply of a resource such as food or living space between species.

Back 25

resource partitioning

Front 26

Species that have a narrow range of niches, such as limited diet, narrow environmental tolerances, and specific habitat (e.g., pandas and spotted owls).

Back 26

specialist species

Front 27

Relationship that occurs when two different species live together in a unique way; it may be beneficial, neutral, or detrimental to one and / or the other species.

Back 27
