Why should we conserve and protect wildlife
• food source - current and future • building material - wood • medicine • clothing • entertainment
What is biomimetics
• developing synthetic materials and structures by mimicking designs found in nature
Examples of biomimetic
• bullet train • aeroplanes
How have squids allowed for medical breakthroughs to be achieved
• have been used to understand sensory and nervous system • they have helped understand dementia
How have armadillos allowed for medical breakthroughs to be achieved
• they have been used in fertility and embryology studies
How have poppies been used in medicine
• morphene , heroin • to treat severe pain
How has the willow tree been used in medicine
• aspirin • to treat pain
Example of a domesticated plant
• wild mustard plant • common veg such as broccoli and cauliflower
Example of a domesticated animal
• red jungle fowl • chicken
What are the potential new food species
• more plant-based materials • insects • fungi
What is a centre of biodiversity
• area of the world that has a high concentration of the close relatives of the important crop species
What does CWR stand for
• crop wild relative
What is a CWR
• they are the wild ‘cousins’ of our cultivated crops
Why are CWR so important
• increase disease resistance • increase hardness • increase drought resistance • increase salt tolerance
What are the current and future risks to a Vavilov centre and to CWR’s
• deforestation • climate change • sea level rises • predation • droughts
What can we do to protect and preserve Vavilov centres and CWR’s
• seed banks • giving areas legal protection • educating • removal of invasive species
What is one example of characteristics introduced to a domesticated food crop from CWR’s
• wild bananas from papua new guinea boost food security for all
What do we mean by the term biological control
• use of a living organism to control pests
Examples of species that are used as biological control
• ground beetles • parasitic wasps
How can predation benefit a species
• can control population size • removes weak genes from the population
Examples of seed dispersal methods
• squirrels • exploding seeds
Two examples of pollination relationships
• humming birds • bats
What are the causes of bee population collapse
• wild flowers being removed • changes in agriculture techniques (nicotine based pesticides)
What are the potential impacts of bee population collapse
• loss of habitats • loss of flowering plants • diseases could be transferred by shipping of hives
