Generation 4

Generation 4: Initial Population Counts

It will be necessary to determine the population size for both predators and prey for the next generation. This can be determined using the following formulas:

The total number of prey species will remain constant from generation to generation; (for 4 prey species the total # will always be 2000, which is equal to the carrying capacity)
% of prey type for next generation =
(# of individuals of that species who successfully avoided predation)
divided by
(total number of prey of all species who avoided predation)

Population size for prey species = 2000 x (% of prey species for next generation)

% Pinto Beans for Gen 4 = _____ x 2000= Pinto Bean Pop. Size = _____

% Red Beans for Gen 4 = _____ x 2000= Red Bean Pop. Size = _____

% White Beans for Gen 4 =_____ x 2000= White Bean Pop. Size = _____

% Split Pea for Gen 4 = _____ x 2000= Split Pea Pop. Size = _____

Generation 4: Predation Counts

Total # Prey captured by Knives ______

Total # Prey captured by Forks ______

Total # Prey captured by Spoons ______

Total All Types_____

% of predator species for the next generation=
(# of individuals that were captured by that predator species)
divided by
(total number of prey captured by all predator species)

Population Size For Next Generation = % x Total # all predator species

% Knives for Gen 4 = _____ Knife Pop. Size = _____

% Forks for Gen 4 = _____ Fork Pop. Size = _____

% Spoons for Gen 4 = _____ Spoon Pop. Size = _____

Predation Counts Generation 4:

Starting # Pinto Beans= ______
Total #Pinto Beans Captured= ______	# avoiding predation= _____
Starting # Red Beans= ______
Total #Red Beans Captured= ______	# avoiding predation= _____
Starting # White Beans= ______
Total #White Beans Captured= ______	# avoiding predation= _____
Starting # Split Peas= ______
Total #Split Peas Captured= ______	# avoiding predation= _____
Total # avoiding predation= _____
