Question 1

Autogenic

Answer 1

Self-generated

Question 2

Allogenic

Answer 2

Refers to successional change brought about by a change in the physical environment

Question 3

Chronosequences

Answer 3

Groups of sites within the same area that are in different stages of succession

Question 4

Early successional species

Answer 4

Plant species characterized by high dispersal rates, ability to colonize disturbed sites, short life span and shade intolerance

Question 5

Intermediate disturbance hypothesis

Answer 5

The concept that species diversity is greatest in those habitats experiencing a moderate amount of disturbance, allowing the coexistence of early and late successional species

Question 6

Late successional species

Answer 6

Long-lived, shade-tolerant plant species that supplant early successional speceis

Question 7

Paleoecology

Answer 7

Study of ecology of past communities by means of the fossil record

Question 8

Pioneer species

Answer 8

Plants that invade disturbed sites or appear in early stages of succession

Question 9

Primary succession

Answer 9

Vegetation development starting on a new site never before colonized by life

Question 10

Sere

Answer 10

The series of successional stages on a given site that lead to a terminal community

Question 11

Seral stage

Answer 11

Following a series of stages; a point in a continuum of vegetation through time

Question 12

Secondary succession

Answer 12

Development of vegetation after a disturbance
