Biogeography & Diversity

Question 1

Existence/intrinsic values

Answer 1

Value in its own right and for it’s own sake, doesn’t need to be useful to humans or anything else to deserve respect

Question 2

Geodiveristy

Answer 2

Diversity of landsforms on earth, with respect to their geology, geomorphic form and processes, soils present

Question 3

Sustaining processes

Answer 3

Geomorphic processes such as water flow, wave action, wind action that maintain a geomorphic landform

Question 4

System support values

Answer 4

Contribution of geodiveristy to ecological processes - geodiversity contributes habitat variety

Question 5

Active dispersal

Answer 5

Organism provides the motor power

Question 6

Biotic resistance

Answer 6

Repulsion of invaders by nature

Question 7

Center of local endemsim

Answer 7

Concentration of species within small ranges

Question 8

Disjunct distribution

Answer 8

One that contains a gap that is larger than the normal dispersal range of the organism

Question 9

Disseminule

Answer 9

Part of an organism that can be dispersed to create a new individual (.e.g rhizome, seeds)

Question 10

Ecotozoic dispersal

Answer 10

Movement of disseminules on the outside of animals

Question 11

Endozoic dispersal

Answer 11

Movement of disseminules on the inside of animals

Question 12

Metapopulation

Answer 12

A group of populations occasionally linked by gene flow

Question 13

Migration

Answer 13

Occuers when dispersal results in establishment and reproduction

Question 14

Passive dispersal

Answer 14

Forces or entities independent of the species being dispersed carry the disseminule

Question 15

Reugia

Answer 15

Places where species retreat in inclement times

Question 16

Relict species

Answer 16

Had a much wider distribution in the past than at present

Question 17

Vector

Answer 17

Force of entity responsible for the carriage of disseminules
