Question 1

What is Alpha Gamma Beta Diversity

Answer 1

A- num of species in a local assemblage, B- num of species between communities, G- num of species occurring across a region

Question 2

What happens when the size of the area goes up

Answer 2

Num of species goes up

Question 3

(Issues of scale) what is sampling

Answer 3

larger areas = more species

Question 4

(Issues of scale) what is Habitat diversity

Answer 4

larger areas = more habitats

Question 5

(Issues of scale) what are colonization/extinction dynamics

Answer 5

lower colonization rate = more species, more extinction rates

Question 6

(Issues of scale) what are speciation/extinction dynamics

Answer 6

larger area = more speciating rate, lower extinction rate

Question 7

what are the 5 factors that explain marine vs. terrestrial biodiv

Answer 7

life began in see, terrestrial environments are more heterogeneous, ocean bed is less architecturally elaborate, patterns of herbivory differ, body size distribution differ

Question 8

when is a species counted as endemic?

Answer 8

when it only naturally occurs there and nowhere else

Question 9

what are neoendemics

Answer 9

evolved recently

Question 10

what are paleoendemics

Answer 10

evolutionary relics

Question 11

the distribution of species seem to observe more of a natural distribution trend in terms of gradient, which is largely explained by the __

Answer 11

intermediate disturbance hypothesis
