Abstract:
Alan Feduccia, professor of biology, challenges the view that birds evolved from dinosaurs. He thinks that birds began evolving long before the hypothetical first bird, Archaeopteryx.

Abstract:
A key was prepared for the shell-less opisthobranch gastropods reported as occurring on the Atlantic coast from South Carolina to New Jersey. Forty-seven species were keyed out using primarily external characteristics.

Abstract:
Biology doctoral candidate Jonathan Parkinson is researching patchy ephemeral resources, transient habitats such as mushrooms that sprout after it rains. He believes his work in patch dynamics has practical applications in conservation and agriculture.

Abstract:
Various theories have attempted to explain color abnormalities in the southern flounder (Paralichthys lethostigma). Specimens of southern flounder were collected in Core Sound, North Carolina and examined. Observations contradict previous theories and suggest ambicoloration and abnormalities may be the result of other developmental factors.

Abstract:
Biological features of five species of carangid fishes (African pompano, Atlantic bumper, rainbow runner, leatherjack, and cottonmouth jack) were examined. Abundance and presence of all five species in ocean or inland waters of North Carolina were influenced by habitat or water conditions.

Abstract:
Dr. Jason Bond, professor of biology at East Carolina, has just received three National Science Foundation grants to study spiders and millipedes. The research will focus on cataloging species from around the world, examining biodiversity and evolutionary biology with the aid of undergraduate and graduate students.

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:
Biology undergraduates are working with Seth Reice, chair of the Ecology Curriculum, to examine New Hope Creek for their senior theses. They will study the various physical influences that cause macro-invertebrate species, called benthos, to select particular stream habitats.

Abstract:
Researchers at East Carolina University conducted a study of tiger beetle (Megacephela carolina carolina) behavioral responses to simulations of bat echo location calls. Results reveal a host of acoustic startle response behaviors, suggesting that tiger beetles may have evolved hearing organs as a direct result of the hunting pressures exerted by insectivorous bats.

Abstract:
There is a diverse freshwater silica-scaled chrysophycean algal flora for the Carolina Piedmont and Mountain Regions, including several new taxa. This study presents an account of the scale-bearing chrysophytes from the Carolina Coastal Region, which were observed using scanning and transmission electron microscopy.

Abstract:
Woodrats are species in the rodent genus Neotoma. Specimens of Neotoma from West Virginia, North Carolina, and South Carolina were karyotyped using standard techniques and examined.

Abstract:
Atlantic menhaden fish were collected from purse-seine catches at Reedville, Virginia and Beaufort, North Carolina in 2003. The fork length to total length and length to weight relationships are presented to help investigators have more precise biostatistical information on forage fishes.

Abstract:
The blue ghost firefly (Phausis reticulata) is a lampyrid beetle found in the southern Appalachians, observed primarily in May and June. Its behavior and habitat were observed at several locations in North Carolina, Tennessee, Georgia, and South Carolina from 1997 through 2008.

Abstract:
Naked soles (Gymnachirus melas) are now known from 108 specimens collected between 1951 and 2003 off North Carolina ocean waters. Standard lengths, total lengths, capture depths, and capture locations of the naked soles were documented, but much remains unknown about their distribution, abundance, and biology.

Abstract:
The wood-feeding cockroach Cryptocercus harbors wood-digesting protists related to those in the guts of termites. The protest symbionts of a population of Cryptocercus from northeast Georgia were examined to determine if species-specific bacteria are associated with the protists.
