quiz 4 Ch 12

Question 1

timing of life events

Answer 1

life stages 
age at maturity 
age at 1st reproductive event 
number of reproductive events 
number and size of offspring 
pos reproductive lifespan

Question 2

principle of allocation

Answer 2

cause tradeoffs between functions like maintenance, growth, fat storage, and egg production

Question 3

fish egg size and number

Answer 3

the bigger the female fish the more number of eggs laid

bigger egg sizes = less eggs

Question 4

case study: egg size and number in Darters

hypothesis

Answer 4

population. with many small eggs have fewer allelic frequency than larger eggs

Question 5

case study: egg size and number in Darters

result

Answer 5

large egg larvae hatch earlier feed earlier, don’t drift as far, and don’t disperse great distances

Question 6

greater isolation leads to

Answer 6

rapid gene differentiation

Question 7

4 basic plant forms

Answer 7

graminoids
forbes
woody plants
climbers

Question 8

graminoids

Answer 8

grass and grass like plants

Question 9

forbes

Answer 9

herbaceous, non graminoids

Question 10

woody plants

Answer 10

woody thickening of tissue

Question 11

climbers

Answer 11

climbing plants and vines

Question 12

seed size of 4 plant forms

Answer 12

woody and climbers > graminoids and Forbes

Question 13

6 seed dispersal strategies

Answer 13

unassisted 
adhesion 
wind 
ant 
vertebrate 
scatter- hoarded

Question 14

unassisted

Answer 14

no specialized structures

Question 15

adhesion

Answer 15

hooks, spines, barbs

Question 16

wind

Answer 16

wings, hair, resistance structures

Question 17

ant

Answer 17

oil surface coating

Question 18

elaisome

Answer 18

oil surface coating in seeds

Question 19

vertebrate

Answer 19

fleshy coating

Question 20

aril

Answer 20

fleshy coating on seeds

Question 21

scatter- hoarded

Answer 21

gathered, stored in caches

Question 22

small plants produce

Answer 22

large number of small seeds which are an advantage in disturbed habitats

Question 23

case study: seed size variation cause different recruitment success
result

Answer 23

large seed have increased recruitment

Question 24

larger seeds have

Answer 24

energy reserved to boost seedling rapid growth to help penetrate thick litter layer

Question 25

case study: vertebrate energy budget differ before and after sexual maturity

Answer 25

before - energy for maintenance and growth

after - energy for maintenance growth and reproduction

if they delay reproduction they grow faster and larger

Question 26

adult fish mortality and age of reproductive maturity

Answer 26

spp with higher mortality have higher relative reproductive rates

Question 27

adult survival on pumpkinseed sunfish life history

Answer 27

low adult survival relative to juveniles due to natural selection leads to fish having to allocate more resources to reproduce

Question 28

r selection

M and W

Answer 28

per capita rate of increase show high population growth rate

Question 29

k selection

M and W

Answer 29

carrying capacity have efficient resource use

Question 30

r selection

pianka

Answer 30

unpredictable environments 
high inartistic rate of increase not competitive 
rapid development 
small body size 
semelparity reproduction
many small offspring

Question 31

k selection

pianka

Answer 31

predictable environments 
low inartistic rate of increase competitive 
slow development 
large body size 
iteroparity reproduction
few large offspring

Question 32

2 important variables exerting selective pressure in plants

Answer 32

intensity of disturbance

intensity of stress

Question 33

intensity of disturbance

Answer 33

proces destroys biomass

Question 34

intensity of stress

Answer 34

external constraints limit rate productivity

Question 35

4 environmental extremes

Answer 35

low disturbance: low stress
low disturbance: high stress
high disturbance: low stress
high disturbance: high stress

Question 36

by wine miller and rose

Answer 36

juvenile survivorship
fecundity
age of reproductive maturity

Question 37

charnel key life history featured to dimensionless numbers

Answer 37

remove time and size to make it easier to id similarities and differences btwn groups
