Research Data Sets: Faunal Dynamics

During the past funding cycle we focused our animal monitoring on small mammals because they are important as consumers of seeds, arthropods and other small vertebrates, and as prey for a wide range of predators. They alter the system through their burrowing and mound-building activities and by consuming key plant species. Thus dynamics of small mammals simultaneously reflect and affect both the structure and function of SGS ecosystems. We propose to continue our emphasis on the dynamics and ecological effects of small mammals, synthesizing and building upon our past research success. Broadly, these studies will fall into two areas: 1) a continuation of long-term studies tracking changes in small mammal populations, their resources, and predators; and 2) new research to examine linkages between black-tailed prairie dog (Cynomys ludovicianus) and associated small mammals, plants, underground invertebrates, and microbes. One purpose is to examine dynamics in the face of an introduced disease, sylvatic plague caused by the bacterium Yersinia pestis, which has indirect effects on flora and fauna of SGS because of extinction and re-settlement dynamics of prairie dog towns. Our work on faunal dynamics and ecosystem interactions is organized around 7 hypotheses (F1-F7).
