Kinsella, John Michael, 1941-2005-10-062005-10-061974http://hdl.handle.net/2246/274212 p. ; 24 cm.Includes bibliographical references (p. 9-12)."Twenty-five species of helminths were found in 197 cotton rats, Sigmodon hispidus, from north-central and south-central Florida--including seven species of trematodes, six of cestodes, and twelve of nematodes. Six species of trematodes were restricted to rats from salt marshes. Incidence of four nematodes with free-living larval stages was highest in rats from freshwater marshes, lower in those from saltwater marshes, and lowest in those from more xeric upland habitats. Undescribed species of Raillietina (Cestina) and Gongylonema (Nematoda) were restricted to rats from upland habitats. The cotton rat was found to be an intermediate host of three carnivore tapeworms and to share adult helminths with ecological associates, such as squirrels, rabbits, deer mice and rice rats. A checklist of the helminths of the cotton rat is included"--P.
