Why should we conserve and protect wildlife?
food source medicine - current and future biodiversity ecotourism pollination decomposition atmospheric regulation
What is biomimetics (biomimicry)?
an innovative design concept that draws inspiration from nature and its elements and processes to solve complex human problems
Example of biomimetics: Bullet train
pointed front mimics a kingfisher’s beak reduced noise and energy usage resolved the boom the train made when leaving the tunnel (reduced air resistance)
Example of biomimetics: Velcro
inspired by the burdock plant small hooks found at the end of the burrs are useful for attaching to things velcro uses the same idea of little hooks
Example of biomimetics: Turbine
the bumps on the flippers on the humpback whale allow water to flow over more smoothly fewer turbine blades are needed for the same amount of air flow able to spin in less windy conditions
Medical (physiological) Research: Squid
used to study the nervous system contains the largest known nerve cell able to regenerate their tentacles helped us understand degenerative diseases- dementia, alzheimer’s
Medical (physiological) Research: Cattle
comparable organ size study their reproductive biology - IVF
Medical (physiological) Research: Armadillo
produce up to 4 genetically identical babies at one time - useful for drug testing leprosy research - show similar disease progression to humans
Development of new medicines: Poppies
Opiates morphine/heroin treats chronic pain
Development of new medicines: Cinchona Tree
Quinine treats malaria and swine flu
Development of new medicines: Rosy periwinkle
Vinblastine/Vincristine treats cancer vinblastine - Hodgkins’ disease vincristine - childhood leukaemia
Example of domestication: Red Jungle Foul
domesticated to chickens
What does domestication mean?
adapted over time via selective breeding to live close with humans
Example of domestication: Wild Mustard Plant
domesticated to kale, cabbage, cauliflower, brussel sprouts
Potential new food species
insects fungi plant based foods morama bean
What is a Centre of Biodiversity/Vavilov Centre/Centre of Origin?
an area of the world that has high concentrations of the close relatives of important crop species (before domestication)
What is the negative impact of selective breeding/domestication?
reduces the gene pool
What does CWR stand for?
Crop Wild Relative
What is a CWR?
The wild cousins of our agricultural crops useful for adapting our crops to climate change as they contain the original gene pool
Why are CWRs so important?
More genetically diverse Genetic resource we may need to solve future problems, for example disease resistance, hardiness, drought resistance
What are the current and future risks to Vavilov Centres and CWRs?
Deforestation and habitat clearance- caused by urbanisation, mining, agriculture Contamination of gene pool - GM crops, introduced species Climate Change - droughts, temperature, sea level rise (outside range of tolerance)
What can we do to protect CWRs and Vavilov Centres?
Seed banks Legal protection - national parks, protected status Education - sustainable farming Reduce combustion of fossil fuels Invest in renewable energy Reduce methane emissions Remove invasive species
Examples of CWR characteristics introduced to domesticated crops: Salt tolerant rice
Developed in Vietnam due to increased flooding Able to tolerate increased salinity in order to protect crop yields and food security
Examples of CWR characteristics introduced to domesticated crops: Potatoes
Developed in Peru Adapted common potatoes to survive in poor soils and environments
