When was the classic study derived?
1934
What was the classic study and what were its results?
It was to discover how two organisms would compete and one always out-competed the other.
Small carnivores that consume herbivores e.g., weasels or feral cats.
Define top predators.
Organisms that typically consume both herbivores and predators e.g., wolves and sharks.
How can a stable predator-prey population be achieved?
When an environment is complex and contains some barriers.
What is the Lotka-Volterra model?
A model of predator-prey interactions that incorporates oscillations in predator and prey populations and shows predator numbers lagging behind those of their prey.
What is the formula for the Lotka-Volterra model?
dN/dt = rN-cNP
Define functional response.
The relationship between the density of prey and an individual predator's rate of food consumption.
What are the types of functional response?
1)When a predator's rate of prey consumption increases in a linear fashion with an increase in prey density until satiation occurs.
2)When a predator's rate of prey consumption begins to slow as prey density increases and then plateaus.
3)When a predator exhibits low, rapid and slowing prey consumption under low, moderate and high prey densities.
Define the numerical response.
A change in the number of predators through population growth or population movement e.g., immigration and emigration.
