Why is scale important in Ecology?
Not everything is applicable at every scale.
What are the 4 applications of ecology?
Ecosystem services, agriculture, biodiversity, and urban planning
What are some ecosystem functions of ecology?
Water purification, erosion abatement Air purification, carbon sequestration Pollination, Recreation, fish and wildlife
What corresponds with high biodiversity?
High resilience.
What corresponds with high resilience?
High biodiversity.
What does competition assume?
That resources are in short supply.
What does niche overlap produce?
Higher biodiversity.
How does niche overlap produce higher biodiversity?
It makes the niche breadth smaller. Competition occurs and pushes the species apart to compete for different kinds of the same resource, causing divergence of species.
What does global stability refer to?
There is only one equilibrium point and it conveys high resilience.
What do the bottom and tops of the equilibrium points mean?
The top means low stability because if the ball falls in either direction equilibrium will change. Bottom means high resilience because a little move will end up in the same spot.

What is net primary production?
Accumulation of biomass by plants.
What is quadrant sampling?
laying down PVC pipes in set squares and counting the species inside the square.
What is the order of all grasses that are wind pollinated?
Graminae.
What was shown in the Grassland experiment?
The more species the higher the resistance to change is.
About how many species of birds are left?
~ 9600
About how many species of mammals are left?
~ 4500
