Baseball
When one trait cannot increase without a decrease in another
Trade-off
What is "b" in the exponential growth model?
Birth rate
The maximum population size that a habitat can support
Carrying capacity
Adapted to thrive when population is near its carrying capacity
K-selected
The consuming of one organism by another
Predation
When an individual focuses all their reproductive resources on a single large event and then die
Semelparity
When an area is destroyed and then left alone, it will eventually go back to normal
secondary succession
What is "k" in the logistic growth model?
carrying capacity
Favors individuals with the highest reproductive rates
r-selected
Interactions in which both participating species benefit
mutualism
Organisms that produce offspring several times
Iteroparity
What is "e" in the exponential growth model?
rate of movement out of an area
When factors, such as natural disasters, affect populations regardless of size, this is known as what?
density-independent
Humans are an example of what population?
k-selected
Interaction in which one species benefits but the other is harmed
parasitism
The reduction in future reproductive potential resulting from current reproductive efforts
Why can't a population grow exponentially forever?
Because of shortages of environmental factors such as space, light, water, or nutrients
Why does the size of some populations cycle?
Amount of food available and amount of predators
What is species richness?
number of species present
Species whose effects on the composition of communities are greater than one might expect based on their abundance
Keystone species
What is the exponential growth model?
r = (b-d)(i-e)
What is the logistic growth model?
(dN/dt) = rN(k-N/k)
Occurs when two species use the same resource and there is not enough to satisfy both
What is exploitative competition?
Consuming the same resources
What is coevolution?
The simultaneous development of adaptations in two or more populations, species, that interact so closely that each is a strong selective force on the other
