What is the importance of biodiversity? (7)
Resources Biomimetics Medicine Physiological research Pest control Genetic resource Ecosystem services
What is biodiversity?
Variety of life on earth
Why is conserving biodiversity from medicinal purposes are compelling argument?
Only a small proportion of existing species have been studied for the medicinal substances they contain
What is biomimetics?
Uses the knowledge of adaptions of other species to improve the design of manufactures items
What is physiological research?
The study of functions and mechanisms of living things, ranging from a cellular level to the full organism
What is a crop wild relative?
A species similar to a commercially grown one that has built up desirable characteristics
What are plants desirable characteristics? (6)
Disease tolerance Drought tolerant Salt tolerant High yield Improved taste Increased nutrient uptake
What is a centre of diversity/vavilov center?
Areas of the world which have high concentrations of the close relatives of important crop species. Protection of these species
Give some ecosystem services?
Atmospheric composition Hydrological cycle Biogeochemical cycles Inter species relationships Soil maintenance Food Pollination/seed dispersal
Describe the ecosystem service atmospheric composition?
The composition of the atmosphere is constantly changing but is kept at dynamic equilibrium by biotic and abiotic process ie( photosynthesis and respiration)
Describe the ecosystem service soil maintance?
Soil provides water and nutrients for plants Soil regulates water flow Organic matter and hummus from decomposisition holds soil tight, organic acids help to break down rocks which makes more soil and releases more nutrients
Give three direct threats to biodiversity?
Food Fashion Traditional medicines
Give three indirect threats to biodiversity?
Habitat destruction Introduced species (predators) Changes in abiotic factors (eg land drainage)
What is direct exploitation?
The act or usage of natural resources for the benefit of us
Give a case study example of a threatened species?
Hawain monk seal
What does HIPPO stand for?
Habitat loss Invasive species Population growth Pollution Over harvesting
What are some roles of the IUCN?
Coordinating global data on biodiversity and conservation Increase understanding of importance of biodiversity Developing nature based solutions to global challenges
What does IUCN stand for?
International union for conservation of nature
Why might a species IUCN category change when re assed?
Conservation efforts may have been succesful or species might have been further affected becoming more endangered
What is an endemic species?
A species that’s only found in 1 geographical location
What is an EDGE species?
Species that has a high degree of evolutionary uniqueness and are globally endangered
What does EDGE stand for?
Evolutionary distinct and globally endangered
What’s a flagship species?
A species that has a high public profile
What’s a keystone species?
Species that has an important role in maintaining the ecological structure of a community
