The genus Necturus is a group of aquatic salamanders commonly known as waterdogs and mudpuppies. Of the three species occurring in North Carolina, only the Neuse River Waterdog (Necturus lewisi) is endemic to the state. In 1978, a three-year study began to provide information on its life history, habitat preference, and preliminary conservation status.
The Neuse River Waterdog (Necturus lewisi) is a large, aquatic salamander endemic to the Neuse and Tar River systems of North Carolina. Some of the streams inhabited by the salamander drain lands subject to frequent pesticide applications. This paper reports the results of analysis of tissues to determine pesticide and polychlorinated biphenyl (PCB) residue levels.
The Neuse River Waterdog (Necturus lewisi) is a totally aquatic salamander endemic to the Neuse and Tar River drainages of North Carolina. A study conducted from 1978 through 1980 documented the waterdog’s distribution, ecology and feeding habits. A conservation status of Special Concern may be warranted due the animal’s need for larger streams with relatively clean, flowing water.
Movements, microhabitat selection and home ranges of the Neuse River Waterdog (Necturus lewisi) were studied in the Little River, Wake and Johnston counties, North Carolina, from 1977 to 1981. The study provides information on the animal’s behavior in both its natural environment and the laboratory.
All salamander species of the genus Necturus are found throughout North Carolina and the coastal plain of southeastern United States. This study examined the degree to which chromosome changes have accompanied diversification and divergence within Necturus, and to elucidate the relationship between the geographic distribution and the evolutionary history of this group of salamanders.
