Description:

Objective:

The objective of this research project is to examine the overall health of marsh rice rats living in natural and restored saltwater (brackish) marshes, as well as freshwater marshes in the Sabine National Wildlife Refuge. Through the analysis of hematological, immunological, and hepatological measurements, as well as the examination of endoparasites and ectoparasites, we will determine if populations of rice rats living in any of these habitats may be less able to meet physiological challenges than those living in other types of habitats.
