Life 56- Species Interactions and Coevolution

Question 1

Interspecific competition

Answer 1

Competition between members of two or more species.

Question 2

Mullerian Mimicry

Answer 2

Convergence in appearance of two or more unpalatable species.

Question 3

Fundamental Niche

Answer 3

A species’ niche as defined by its physiological capabilities.

Question 4

Intraspecific competition

Answer 4

Competition among members of the same species

Question 5

Batesian Mimicry

Answer 5

The convergence in appearance of an edible species with an unpalatable species.

Question 6

Coevolution

Answer 6

Evolutionary processes in which an adaptation in one species leads to the evolution of an adaptation in a species which it interacts.

Question 7

Aposematism

Answer 7

Warning coloration; bright colours or striking patterns of toxic or mimetic prey species that act as a warning to predators

Question 8

Exploitation competition

Answer 8

Competition in which individuals reduce the quantities of their shared resources.

Question 9

Resource partitioning

Answer 9

A situation in which selection pressures resulting from inter specific competition cause changes in the ways in which the competing species use the limiting resource, thereby allowing them to coexist.

Question 10

Crypsis

Answer 10

The resemblance of an organism to some part of its environment, which helps it to escape detection by enemies

Question 11

Diffuse coevolution

Answer 11

The evolution of similar traits in suites of species experiencing similar selection pressures imposed by other suites of species with which they interact

Question 12

Arms race

Answer 12

A series of reciprocal adaptations between species involved in antagonistic interactions, in which adaptations that increase the fitness of a consumer species exert selection pressure on its resource species to counter the consumer’s adaptation, and vice versa

Question 13

Guild

Answer 13

In ecology, a group of species that exploit the same resource, but in slightly different ways.

Question 14

Interference competition

Answer 14

Competition in which individuals actively interfere with one another’s access to resource.

Question 15

Homotypic

Answer 15

Pertaining to adhesion of cells of the same type

Question 16

Commensalism

Answer 16

A type of interaction between species in which one participant benefits while the other is unaffected

Question 17

Realised niche

Answer 17

A species’ niche as defined by its interactions with other species.

Question 18

Niche

Answer 18

The set of physical and biological conditions a species requires to survive, grow, and reproduce.

Question 19

Mutualism

Answer 19

A type of interaction between species that benefits both species.

Question 20

Antagonistic interactions

Answer 20

Interactions between two species in which one species benefits and the other is harmed. Includes predation, herbivory, and parasitism.

Question 21

Competition

Answer 21

In ecology, use of the same resource by two or more species when the resource is present in insufficient supply for the combined needs of the species

Question 22

Amensalism

Answer 22

Interaction in which one animal is harmed and the other is unaffected

Question 23

Character displacement

Answer 23

An evolutionary phenomena in which species that compete for the same resources within the same territory tend to diverge in morphology and/or behaviour

Question 24

Competitive exclusion

Answer 24

A result of competition between species for a limiting resource in which one species completely eliminates the other.
