LV Predator Prey Model
What is the equilibrium function for exploiters in a Type 1 Functional Response?
Np=d/cf
Define exclusion
aka displacement of a species from part(s) of its fundamental niche
What are the long term outcomes of competition?
Extinction, Exclusion and Evolution
What is the prey equilibrium?
Ne= r/f
What does this formula illustrate?
dNp/dt= rNp - fNpNe
Prey grow exponentially and are eaten by exploiters at a constant rate.
What is a functional response?
Prey kill rate per predator
If different species of flowers are separated in the sense of flowering season, what is happening?
What happens to prey if there are no exploiters?
They will grow exponentially.
What does this formula illustrate?
dNe/dt= cfNpNe - dNe
Exploiters grow at a constant rate of prey eaten and die at a constant rate.
Define Extinction
can occur if a species is always the poorest competitor and overlap is entire fundamental niche
What states that when two resources compete for the same resource they cannot coexist simultaneously in the same habitat?
Principle of Competitive Exclusion or (-,-) competition
Where is the only place that prey equals zero, and what will change this?
Equilibrium and stochasticity will move this.
If all prey are lost, what happens to exploiters?
Define evolution
can change to traits such a species that avoid competition
Multiple species that use the same resource may partition when/where/how they use the resource to minimize competition. What is this method called?
What happens on the right side of the exploiter boundary?
Exploiters will increase because there are plenty of prey to feed them.
