topic 4 - conservation

Question 1

what is cities and what do they do

Answer 1

convention on international trade in endangered species

they make sure everything is covered eg elephant tusk in piano keys

Question 2

what are the 3 appendix in cities

Answer 2

each appendix can value a list of species with the criteria that the species are protected in

appendix 1 - no trade eg blue whale
appendix 2 - regulates certain species trade eg lions american alligators
appendix 3 - certain populations of each species is needed to trade, country population eg smooth soft shell turtle

Question 3

restrictions of cities

Answer 3

documents needed

rules need to be enforced to do anything

Question 4

what does edge save

Answer 4

evolutionary distinct and globally endangered

the more unusual and rare species are to be saved

Question 5

what does flagship species save

Answer 5

cute and interesting species, high profile species in order to raise awareness eg polar bears lions

Question 6

what do keystone species save

Answer 6

keystone species are species that hold the community together ( disproportionately important )

wolves
otters

Question 7

what are endemic species

Answer 7

species that are usual adapted to certain habitats, specialised in places, they are harder to look after

kiwi
ring tailed lemur

Question 8

roles of the IUCN

Answer 8

coordinating global data on biodiversity conservation

increasing understanding of importance of the importance of biodiversity

deploying nature based solutions to global challenges in climate, food and sustainable development

Question 9

what is the IUCN red list

Answer 9

the most threatened species

categories include amphibians mammals conifers ect

Question 10

what is the importance of conservation of biodiversity

Answer 10

biomimetics ( using animals to improve human ways )

research for new medicines

physiological research

pest control agents

genetic resources

Question 11

resources preserved by biodiversity

Answer 11

woof
fibres
oils
fuels
new foods

Question 12

how biodiversity helps the ecosystem

Answer 12

keeps systems running like
biogeochemical cycles

inter species relationships like bees and flowers which keeps pollination

soil maintenance

the atmospheric composition stays the same

Question 13

the threats to wildlife

Answer 13

direct exploitation

introduced species

deliberate eradication of predators and competitors

change in biotic factors

change in abiotic factors

habitat destruction

Question 14

how is direct exploitation a threat to wildlife

Answer 14

populations of many species have declined as taking animals from wild
targets rarer animals as more desired

affected animals like
tiger turtles snakes

Question 15

how is introduced species a threat to wildlife

Answer 15

a species is brought into an area which is not natural l, this often goes wrong

introduced animals may out compete current species, changes food chain,

affected species
indigenous species, pathogens

Question 16

how does the deliberate eradication of predators and competitors threaten wildlife

Answer 16

many species have been killed due to threat to humans
humans go around killing predators like bears

proves a species is bad so incentive and removes entire species from area

threatens predators like
sharks
poisonous snakes
crocodiles

Question 17

how do changes in biotic factors threaten wildlife

Answer 17

humans are killing of many other species which can be crucial for one another such as honey bees

changes in the presence or abundance of the other species in its habitat, survival of other species affected

impacts
animals that eat seeds and fruit which can be vital in seed dispersal
the decline in the populations of some species has been caused
many plants rely on pollen being transported

Question 18

how do changes in abiotic factors threaten wildlife

Answer 18

human activities may alter a habitat so that it becomes unsuitable for species that are not adapted to the new conditions

although the habitat has not been destroyed the conditions have changed so that they become outside the species tolerance

effected species
species with very specialised habitat requirements often already rare species eg lemurs

Question 19

how does habitat destruction threaten wildlife

Answer 19

humans have caused huge habitat destruction due to land use changes, deforestation, mineral extraction, urban expansion ( some areas conserved )

without habitat a species will die out extremely quickly, also extremely bad for the planet

main affected areas are
amazon rainforest 20 second football pitch
this is home to thousands of species many of which only live in that area
