how do populations differ?
2
Populations DIFFER in SIZE DENSITY DISTRIBUTION (SPACING)
3
Populations DIFFER in SIZE (NUMBERS) DENSITY DISTRIBUTION (SPACING)
4
Population sizes differ all over the place…
SMALL TOWNS BIG CITIES
5
SIZE (numbers) DENSITY Populations DIFFER in DISTRIBUTION (SPACING)
INCREASING POPULATION SIZE usually means INCREASING POPULATION DENSITY…WHY? SIZE (numbers) DENSITY DISTRIBUTION (SPACING)
6
We only have so much room here!
7
If country size = population size:
8
DISTRIBUTION (SPACING)
Populations DIFFER in SIZE (numbers) DENSITY DISTRIBUTION (SPACING) ARE THERE ANY PATTERNS?
9
ALL OF THESE ARE INTERCONNECTED.
Populations DIFFER in ALL OF THESE ARE INTERCONNECTED. SIZE (numbers) DENSITY DISTRIBUTION (SPACING)
10
Let’s do a foldable…
11
Fold your paper lengthwise
12
Ink darkly the 2 cells above and 3 cells below
13
Now, On the front side (in pencil or pen) fill in the TOP 2 cells with the following information:
LOW POPULATION DENSITY HIGH POPULATION DENSITY
14
It’s not just the MASS of something.
What is density? It’s not just the MASS of something.
15
What is density? MASS per VOLUME (m/v)!
16
What is density? MASS per VOLUME (m/v)! 3-D SPACE
17
density (m/v) is a _ _ _ _ _ _ _ _ property of both matter and populations.
LOW HIGH
18
density (m/v) is a physical property of both matter and populations.
LOW HIGH
19
Write THE simple definitionS:
LOW POPULATION DENSITY Less individuals, _____ space HIGH POPULATION DENSITY MORE individuals, _____ space.
20
Write the simple definition:
LOW POPULATION DENSITY LESS individuals in MORE space HIGH POPULATION DENSITY MORE individuals, LESS space.
21
Now, work together and find examples of these terms in the textbook!
LOW POPULATION DENSITY LESS individuals, MORE space Examples: HIGH POPULATION DENSITY MORE individuals, LESS space.
22
history question: Why is the us population density the way it is?????
26
You should all have numerous examples….
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space.
27
Let’s get more specific ABOUT POPULATION SPACING.
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space.
28
DISTRIBUTION (SPACING)
Populations vary in SIZE DENSITY DISTRIBUTION (SPACING)
29
3 TYPES OF POPULATION DISTRIBUTION (SPACING).
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING CLUMPED SPACING
30
“clumped” spacing around what?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING CLUMPED SPACING
31
“clumped” spacing around what?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING CLUMPED SPACING
32
“clumped” spacing around what?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
33
WHO CAN DRAW WHAT “UNIFORM” SPACING MIGHT LOOK LIKE?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
34
WHO CAN DRAW WHAT “UNIFORM” SPACING MIGHT LOOK LIKE?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
35
WHO CAN DRAW WHAT “UNIFORM” SPACING MIGHT LOOK LIKE?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING A FAIR, EVEN way to MAXIMIZE RESOURCES! CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
36
DO you think “random” spacing is under MORE or less stress?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING A FAIR, EVEN way to MAXIMIZE RESOURCES! CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
37
DO you think “random” spacing is under MORE or less stress?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING UNIFORM SPACING A FAIR, EVEN way to MAXIMIZE RESOURCES! CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
38
DO you think “random” spacing is under MORE or less stress?
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING RARE, LITTLE or NO STRESS over RESOURCES UNIFORM SPACING A FAIR, EVEN way to MAXIMIZE RESOURCES! CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION!
39
MAKE SURE YOU HAVE THIS DOWN!
LOW POPULATION DENSITY Less individuals, more space Examples: HIGH POPULATION DENSITY More individuals, less space. RANDOM SPACING RARE, LITTLE or NO STRESS over RESOURCES (dandelions) UNIFORM SPACING A FAIR, EVEN way to MAXIMIZE RESOURCES! (penguin nests) CLUMPED SPACING USUALLY AROUND RESOURCES or for PROTECTION! (wolves, water buffalo)
