Q

Rain shadow effect

A

air rises over mountains and cools –> rain falls
dry air creates desert conditions (rain shadow)

14
Q

Evenness

A

the relative abundance of each species in a community

15
Q

Intermediate Disturbance Hypothesis

A

high disturbance favors r-selected species and has weak competition
low disturbances favors K-selected and has strong competition

16
Q

Primary Succession

A

occurs when a disturbance removes the soil and its organisms plus the organisms that live above the surface

17
Q

Secondary Succession

A

occur when disturbance removes some or all of the organisms in an area but leaves the soil intact

18
Q

High Productivity Hypothesis

A

high productivity –> quick speciation, decreasing extinction –> intense competition –> increased niche differentiation

19
Q

Energy Hypothesis

A

Areas with more energy will support more species because energy is divided among different species, so there are more. Equator gets direct sunlight

20
Q

Area and Age Hypothesis

A

tropical regions weren’t covered/scoured by glaciers during ice ages so have had more time for speciation

21
Q

Allee Effect

A

a phenomenon by which some species will refuse to mate when density is too low. This contrasts most species where population growth is higher when density is low.

22
Q

Maximum sustainable yield

A

maximum sustainable yield is theoretically, the largest yield that can be taken from a species’ stock over an indefinite period

23
Q

density independent

A

r-selected species

24
Q

density dependent

A

K-selected species

25
Q

Fundamental Niche

A

ideal conditions niche

26
Q

Realized Niche

A

actual niche

27
Q

Energy flow

A

passes one way through ecosystems

28
Q

Nutrient cycling

A

cycle of chemical elements through the ecosystem

can be recycled

29
Q

Primary Production

A

amount of light energy converted to chemical energy by photoautotrophs or chemoautotrophs

30
Q

Secondary Production

A

food webs

31
Q

CHIPPO

A

Climate Change
Habitat Destruction
Invasive Species
Pollution
Population Growth
Overharvesting

32
Q

Pools/sinks

A

reservoirs where materials are stored up

33
Q

fluxes

A

flow of materials between pools
Organic and Inorganic

34
Q

Top Down Control

A

a predator at the top is overpopulated and eats all of the prey controlling population

35
Q

Bottom Up Control

A

at the bottom there are less organisms, so the predators don’t have enough prey and are regulated

36
Q

Hadley Cell

A

Generated through the convection of air as a result of uneven warming by the sun
