topic 4 - conservation Flashcards
(19 cards)
what is cities and what do they do
convention on international trade in endangered species
they make sure everything is covered eg elephant tusk in piano keys
what are the 3 appendix in cities
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
restrictions of cities
documents needed
rules need to be enforced to do anything
what does edge save
evolutionary distinct and globally endangered
the more unusual and rare species are to be saved
what does flagship species save
cute and interesting species, high profile species in order to raise awareness eg polar bears lions
what do keystone species save
keystone species are species that hold the community together ( disproportionately important )
wolves
otters
what are endemic species
species that are usual adapted to certain habitats, specialised in places, they are harder to look after
kiwi
ring tailed lemur
roles of the IUCN
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
what is the IUCN red list
the most threatened species
categories include amphibians mammals conifers ect
what is the importance of conservation of biodiversity
biomimetics ( using animals to improve human ways )
research for new medicines
physiological research
pest control agents
genetic resources
resources preserved by biodiversity
woof fibres oils fuels new foods
how biodiversity helps the ecosystem
keeps systems running like
biogeochemical cycles
inter species relationships like bees and flowers which keeps pollination
soil maintenance
the atmospheric composition stays the same
the threats to wildlife
direct exploitation
introduced species
deliberate eradication of predators and competitors
change in biotic factors
change in abiotic factors
habitat destruction
how is direct exploitation a threat to wildlife
populations of many species have declined as taking animals from wild
targets rarer animals as more desired
affected animals like
tiger turtles snakes
how is introduced species a threat to wildlife
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
how does the deliberate eradication of predators and competitors threaten wildlife
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
how do changes in biotic factors threaten wildlife
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
how do changes in abiotic factors threaten wildlife
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
how does habitat destruction threaten wildlife
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
