Serengeti: nature's living laboratory
Wildebeest
increased until 1.4M(carrying capacity 1.3 million maximum) - largest number of herbivore in the world
damage to environment & lack sustainability
Reasons why the population rapidly increased
producers - bottom up
population limited by food supply during the dry season
2, predators - top down
wildebeest are better at avoiding from the predators
impacts
Lack of resources
growing out of control
Population pyramid
Primary producers that gets E from the sun but gets eaten by the herbivores like wildebeest. Then, they are eaten by the predators like lions
migrants VS residents
migrants - more # of species dead by the predators b/c they are better to avoid from the predators
residents - less # of species dead by the predators b/c predators aren't as fast as the migratory so they tend to catch residents
keystone species
they are an organism that helps to hold the system together
Buffalo
increase in numbers
almost 75,000
increased rapidly, but eventually they stopped increasing in population
less fire
more young trees growing in the grassland
more bird & mammals --> population increased
less fire = more population of wildebeest
