Which of the following would be unlikely to contribute to large fluctuations in population size?
A) Frequent environmental disturbance
B) A high death rate
C) A density-dependent birth rate
D) A high birth rate
E) Seasonal variation in temperature

A density-dependent birth rate would tend to stabilize population size because as population density increases, the birth rate decreases, helping to keep the population in check. The other options - frequent environmental disturbance, high death rate, and high birth rate - all have the potential to cause large fluctuations in population size depending on the circumstances. Seasonal variation in temperature may have some effect on population fluctuations, but it would likely be less significant than the other factors listed.
