Q

legal legislations

A

wildlife and countryside act 1981
SSSI, NNR, Ramsar sites
CITES-appendix 1-no trade
IWC-aboriginal subsistence+quotas+japan
CFP-catch quootas+net mesh size
ITTO-sustainable timber

17
Q

difficultoiies of ex situ

A

habitat size
food requirementplankton fish
species interelationships-plants mymccorhizal root fungi
cost

18
Q

inhibtion of successful breeding

A

seasonal

breeding habitat-mirror flamingos
gene pool
hybridisation

19
Q

increasing breeding success

A

cryopreservation
artificial insemintation
embryo transfer-bongo common eland -hormones stimulate ovulation
micro-propogation
cloning

20
Q

successful releases programmes

A

reliable food source
low predation risk
local human pop. support

21
Q

how do soft releases help increase likelihood of survival

A

recognise food and poison
hunting skills
avoid predators
accepted into wild social groups

22
Q

habitat conservation approaches

A

land ownership-ngo-rspb
deignated protected areas-sssi nnr spa
voluntary agri-environemntal schemes-
famers gain subsidies -keep beetle banks
low input on grassland-protects wildflowers

23
Q

seed banks -

A

stored in dry cold conditions-maintains biodiversity-10,000 per species-millenial seed bank

24
Q

habitat creation

A

unintentional - old quarry floods
intentional habitat s-understanding of abiotic and biotic factors

25
Q

things you have to think about for designing a habitat design not in a zoo

A

habitat area
biological corridors-linking isolated areas
habitat diversity-greater range of niches easier for animals to colonise
water depth
light levels

26
Q

provisioin of abiotic factors in habitats

A

water
dissolved oxygen
temperature
light levels
pH-denatures proteins
salinity opossum shrimp need high slat

27
Q

control of biotic factors

A

food
control of predation-scilly isles rat readictation
control of competitors -removal of rhodededron bush to increase wildflower populations
contorl of pathogens -density dependent -reomve weakest to reduce chance of break out of disease
rewilding-yellowstone1926

28
Q

control of ecological succession

A

grazing-prevents establishment of taller plants
mowing
burning
coppicing
pollarding

29
Q

broadleaf woodland
features
threat
managemnet

A

no extremes-water all year
fertile soils
high biodiveristy
threat
clearance+fragmentation
copppicing+planting mixed species
dpa

30
Q

tropical rainforest

A

stable-warm regular rainfall
rapid decay-shallow DOM
threats-
timber harvetsing
alternative ladn use -reservoirs+mineral extraction
conservation -
debt for nature swaps-usa+Brazil-21 million

31
Q

tropical coral reefs

A

symbiotic alage-zooxanthellae inside polyps-absorb light provides glucose +oxygen
coral gives it c02
ECOLOGICAL FEATURES
temperature-25-29 degrees -bright sunlight
low turbidity
IMPORTACE -fisheries medicinal discovery sponge in Caribbean-AZT- HIV
climate control + tourism
threats
physical damage, sedimentation, coral bleaching introduced species, fishing
conservation- fishing quotas,tourism controls
sustainable exploitation
reef creation

32
Q

deep water coral

A

dont have algae-slower gtrwoth rate
threats- deep water trawling killed sea bed creatures-exlpoitaation of oil and gas
easy to exploit fish slo wgroeeth rate
ocean acidifaction
SAC

33
Q

oceanic islands

A

features isolation of biodiversity
endemic+edge species
lack of predators
importance medicines
threats
introduced species habiuta destruction-sea elvels
exploitation of species
conservation
culling of animals

34
Q

mangroves

A

halophytic trees live near intertidal range-good in stormy weather
importance
large biodiverse
coastal erosion-reduce wave energy on vulnerable-coral reefs-less sedimentation coastline
fisheries
medicine
threats aquaculture +urban ports
conservation
designated protected areas 2015

35
Q

antartica

A

pristine low temp high marine nutrients-surface water bought up from seabed,seasonal variation
importamce
70% freshwater+high surafce albedo
krill -large mineral deposits
isolated
threats-global cc
ozone depletion-plankton harmed
tourism +overfishing+future mineral extraction
conservation
antartic treaty
control of tourism
waste managemnt
no mineral extraction +military testing
