Abstract:

The giant panda, Ailuropoda melanoleuca, is a highly specialized carnivore whose diet consists almost entirely of various species of bamboo. Bamboo is a family of grass species that often exhibit synchronous semelparity. That is, all the bamboo of a given species in a given area tend to flower and die at the same time. This can create localized drops in carrying capacity for the giant panda.
We create a model using STELLA, a flow modeling language, to examine the population dynamics of the giant panda and explore long term bamboo panda interactions. The model was particularly sensitive to rate changes in birth rates and juvenile survivorship. The populations in the model were also sensitive to losses of adult reproductive age individuals. Bamboo die-offs were most severe when the periods between flowering were longest.
