Footprints in the sand: independent reduction of subdigital lamellae in the Namib–Kalahari burrowing geckos
(East Carolina University, 2006-04-07)
Many desert organisms exhibit convergence, and certain physical factors such as windblown sands have generated remarkably similar ecomorphs across divergent lineages. The burrowing geckos Colopus, Chondrodactylus and ...
Molecular phylogenetic evidence for a mimetic radiation in Peruvian poison frogs supports a Müllerian mimicry hypothesis.
(East Carolina University, 2001-12-07)
Examples of Müllerian mimicry, in which resemblance between unpalatable species confers mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found when the colour and pattern of a single ...
Simultaneous Positive and Purifying Selection on Overlapping Reading Frames of the tat and vpr Genes of Simian Immunodeficiency Virus
(East Carolina University, 2001-09)
Tat-specific cytotoxic T cells have previously been shown to exert positive Darwinian selection favoring amino acid replacements of an epitope of simian immunodeficiency virus (SIV). The region of the tat gene encoding ...
An Archaeological Investigation of Barber Landing, Pitt County, North Carolina
(East Carolina University, 2009)
Twelve sites, including a modern farmstead, were discovered in 1976 by Dr. David Phelps of East Carolina University (ECU) during a Cultural Resource survey of 335 acres along Barber Creek for Greenville Utilities Commission ...
Analyzing Estuarine Shoreline Change in Coastal North Carolina
(East Carolina University, 2009)
With continued climate change, sea-level rise, and coastal development, concern about shoreline dynamics has expanded beyond oceanfront areas to encompass more protected coastal water bodies, such as estuaries. Because ...
A high marsh transfer function for sea-level reconstructions in the southern Bay of Biscay.

Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems
(East Carolina University, 2004-06-22)
Ecosystem-level impacts of two hurricane seasons were compared several years after the storms in the largest lagoonal estuary in the U.S., the Albemarle-Pamlico Estuarine System. A segmented linear regression flow model ...
Latitudinal difference in biodiversity caused by higher tropical rate of increase
(East Carolina University, 2002-06-11)
Tropical diversity has generally exceeded temperate diversity in the present and at points in the past, but whether measured differences have remained relatively constant through time has been unknown. Here we examine ...
Festival Gap : Comparing Organizers' Perceptions of Visitors to a Survey of Visitors at the Carolina Renaissance Festival, 2005
(East Carolina University, 2006)
In many cases, festival organizers simply "guess" at the characteristics and motivations of their visitors. The organization, planning and marketing of festivals can greatly benefit from an analysis of visitors. This ...
Cedar on the reef : archaeological and historical assessments of the Eighteenth-Century Bermuda Sloop, exemplified by the wreck of the Hunter Galley
(East Carolina University, 2003)
The purpose of this thesis is to examine whether the remains of a shipwreck lost on the reefs, near Hogfish Cut, south of Pompano Flats, approximately 600 yards off the southwest shore of Bermuda represent a Bermuda sloop. ...
