Community ecology

Question 1

interspecific

Answer 1

different species

Question 2

intraspecific

Answer 2

within species

Question 3

biotic

Answer 3

living

Question 4

abiotic

Answer 4

non-living

Question 5

intraspecific behaviour

Answer 5

mating/social

Question 6

group

Answer 6

same species that can breed together

Question 7

community

Answer 7

multiple species

Question 8

taxonomic group

Answer 8

all amphibians

Question 9

guild

Answer 9

species that use same resources

Question 10

functional group

Answer 10

species that function in same way but dont use same resources

Question 11

metapopulation

Answer 11

geographically isolated populations linked by separation

Question 12

subpopulation

Answer 12

dispersed groups of metapopulations

Question 13

geneflow

Answer 13

exchange of alleles from one population to another

Question 14

patch

Answer 14

area where animal lives

Question 15

patch potential

Answer 15

chance of extinction or recolonisation, some are at carrying capacity, some have good light/nutrients

Question 16

community ecology

Answer 16

focuses on direct/indirect interactions

Question 17

population ecology

Answer 17

focuses on population size/composition over time

Question 18

interspecific competition

Answer 18

usually for resources, one usually outcompetes another

Question 19

mutualism

Answer 19

benefits both species (pollination)

Question 20

direct interactions

Answer 20

eating other animals, being preyed on

Question 21

indirect interactions

Answer 21

rummaging soil can disturb plants growing there

Question 22

keystone species

Answer 22

species that have community wide effects (wild boars)

Question 23

ecosystem engineers

Answer 23

beavers

Question 24

why do communities change overtime

Answer 24

climate change, resource depleting

Question 25

factors affecting populations

Answer 25

dispersal, predator/prey, resources

Question 26

dispersal types

Answer 26

active (mix/leave with others), passive (birds spread seeds), facilitated

Question 27

what does dispersal do

Answer 27

help reduce competition/escape harsh environments

Question 28

specific dispersal stage

Answer 28

eggs/sperm or before sexual maturity to prevent inbreeding (lions)

Question 29

sex biased dispersal

Answer 29

females more likely to disperse

Question 30

migration

Answer 30

movement of population

Question 31

immigration

Answer 31

to location

Question 32

emigration

Answer 32

from location

Question 33

population growth (exponential/logistic)

Answer 33

exponential (growth then stationary then decline), logistic (limited by resources)

Question 34

density dependant factors

Answer 34

things that depend on dense areas, limiting resources (more animals using resources), predation (more predation), pathogens (more animals to spread)

Question 35

density independent factors

Answer 35

dont depend on density, weather/climate

Question 36

larger organisms mean

Answer 36

density declines as needs more resources

Question 37

survival/mortality types

Answer 37

type 1 (high survival through adulthood), type 2 (constant risk of mortality), type 3 (low survival at early life but increases with age)

Question 38

life history strategies

Answer 38

trade off between number of organisms and size

Question 39

community/population

Answer 39

community (direct/indirect, competition, keystone, engineers, mutualism/commensalism), population (dispersal, migration, factors)
