Populations & Extinction
Understanding populations and how they interact with their environments is what field of study?
Population Ecology
Why did HIPPO used to be reversed(OPPIH)
Because the primary driver was overexploitation.
Is conservation 1 of the 3 approaches to maintaining the health of the world?
Yes
True or false:
Restoration is not the second approach to maintaining the health of the world
false
True or False:
wildlife reserves are too small
True
When was the first mass extinction?
500 million years ago
What is the bad thing about invasive species?
They have not evolved to be susceptible to predators, parasites, and diseases.
About how many species are listed by the IUCN as threatened with extinction?

What are rainforests called and why?
Biodiversity hotspots because they have the richest and most threatened reservoirs of species in the world.
What is the use of a hotspot approach?
It is used as a way to identify the areas that are the most critical to preserving biodiversity

True or False:
Osprey are not attracted to poles and towers
False
What is the impact of species going extinct and give an example.
Our ecosystem won't be balanced.
What does HIPPO stand for?
Habitat destruction, invasive species, pollution, population, and overexploitation
How can conservation be achieved? (and give 2 examples)
Establishing protected places.
Ex. reserves, refuges, parks, private lands with special legal protection
According to the Society for Ecological Restoration what is ecological restoration?
It is the process of assisting the recovery of an ecosystem that has been damaged.
