Abstract:
A survey of streams in the Great Smoky Mountains National Park revealed low populations of hellbenders (Cryptobranchus alleganiensis) and mudpuppies (Necturus maculosus). Water quality profiles indicated acidic conditions for Little River and Noland Creek, suggesting that monitoring efforts should be continued.

Abstract:
A large bulleye, Cookeolus japonicas (Family Priacanthidae), was caught March 2, 2001, by a commercial hook-and-line fisherman, southwest of Beaufort Inlet, North Carolina. This new North Carolina specimen is the largest in North Carolina and the second largest reported in the Northwest Atlantic.

Abstract:
Aletris is a genus of flowering plants which has a disjunct distribution in eastern North America and eastern Asia. A complete distribution of Aletris has not been documented until now. Distribution and habitat information were recorded from correspondence with herbarium curators and from specimens obtained from North Carolina State University, University of North Carolina at Chapel Hill, and other universities.

Abstract:
Researchers at the University of North Carolina at Wilmington conducted a study of two species of voles in genus Microtus. The results suggest a significant difference in age-specific mass in infants of these two vole species, but growth rates do not differ.

Abstract:
Biologists at East Carolina University conducted a study of the distribution of chondroitin sulfate glycosaminoglycans in the human chorio-amnionic membrane complex. The study utilized immunohistochemistry to localize the antigens. Results suggest creation of a boundary between fetal and maternal tissues and possible participation in regulation of amniotic fluid transport.

Abstract:
The sheepshead minnow or sheepshead pupfish (Cyprinodon variegatus) is a species of fish found in saltmarsh and estuary environments, and is native to the eastern coast of North America. This study investigated the effects of salinity on the oxygen carrying capacity of the blood of C. variegatus.

Abstract:
The gnathiid isopod, Bathygnathia depaolorosae, is a new marine crustacean species described from a single specimen collected off the North Carolina coast. Gnathia brucei, a second new species, is described on the basis of specimens from three stations off Cape Lookout, North Carolina.

Abstract:
Researchers at the University of North Carolina at Chapel Hill, Institute of Marine Sciences examined the bilateral asymmetry of forty smalltooth sawfish (Pristis pectinata) rostral width, rostral tooth number variation, and rostral tooth surface areas by age. The purpose of the study was to resolve confusion regarding these factors, and how they may relate to other species of sawfishes.

Abstract:
Cosmopolitan occurring ocean sunfishes or molas, Mola mola and Mola lanceolata (family Molidae), have been documented in North Carolina waters by a number of marine scientists. Frank Schwartz of the University of North Carolina at Chapel Hill, Institute of Marine Sciences updated information on both molas in relation to seasonal occurrences in ocean and estuarine waters, food, age, and additional fish associations.

Abstract:
Seven species of batfishes were collected between 1968 and 2002 at shallow to deep water Atlantic Ocean stations located from North Carolina to Florida. New information reveals extended distributions of the batfishes, and biological characteristics that can be used to distinguish between batfishes.

Abstract:
Spatial and temporal variation in anuran calling activity of four frog species was monitored at two ponds in the western Piedmont of North Carolina. Information on anuran calling patterns can be used to evaluate amphibian populations and improve monitoring programs.
