Male Choice in the Stream-Anadromous Stickleback Complex
(2012)
Studies of mating preferences and pre-mating reproductive isolation have often focused on females, but the potential importance of male preferences is increasingly appreciated. We investigated male behavior in the context ...
Widespread impact of horizontal gene transfer on plant colonization of land
(2012-10)
In complex multicellular eukaryotes such as animals and plants, horizontal gene transfer is commonly considered rare with very limited evolutionary significance. Here we show that horizontal gene transfer is a dynamic ...
Ancient gene transfer from algae to animals: Mechanisms and evolutionary significance
(2012)
Background
Horizontal gene transfer (HGT) is traditionally considered to be rare in multicellular eukaryotes such as animals. Recently, many genes of miscellaneous algal origins were discovered in choanoflagellates. ...
Characterizing the vegetative phenotype of fzt maize mutant
(East Carolina University, 2012)
microRNAs are short, non-coding RNA strands that regulate gene expression post-transcriptionally in all multicellular organisms. miRNAs begin as a hairpin in the nucleus. The primary miRNA (pri-miRNA) and preliminary ...
DETECTION AND DISTRIBUTION OF THE AMPHIBIAN FUNGAL DISEASE CHYTRIDIOMYCOSIS IN PERUVIAN AMPHIBIANS
(East Carolina University, 2012)
Chytridiomycosis is an amphibian disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd;Longcore et al. 1999). This disease has been identified by the Amphibian Conservation Action Plan as one of the main ...
A Study of the Abundance, Distribution, and Grazing Effects of Zooplankton in the Chlorophyll Maximum (CMAX) of the Neuse River Estuary, North Carolina
(East Carolina University, 2012)
Phytoplankton tend to accumulate in distinct zones referred to as chlorophyll maxima, or CMAX. A pronounced CMAX occurs in the Neuse River Estuary (NRE), North Carolina, where as much as over 60% of the estuary's phytoplankton ...
Spatio-Temporal Expression of Chondroitin Sulfate Antigens in Early Chick Pituitary and Thyroid
(East Carolina University, 2012)
The chondroitin sulfate antigens d1C4 and TC2 have been hypothesized to play a role in cartilage differentiation in the limb and early morphogenesis of the heart in chick embryos. The antibody d1C4 recognizes a native ...
Distribution Patterns of Juvenile Spotted Seatrout (Cynoscion nebulosus) and Red Drum (Sciaenops ocellatus) Along Shallow Beach Habitats in Pamlico River, North Carolina
(East Carolina University, 2012)
The association of juvenile spotted seatrout (Cynoscion nebulosus) and red drum (Sciaenops ocellatus) with Submerged Aquatic Vegetation (SAV) is well documented. However, their association with other estuarine habitats ...
Characterizing Environmental and Physicochemical Conditions in Nursery Areas of River Herring in Chowan River, North Carolina
(East Carolina University, 2012)
Anadromous fishes such as blueback herring Alosa aestivalis and alewife A. pseudoharengus, utilize sounds, rivers, and tributaries during spawning. Collectively known as river herring, these two ecologically important ...
Anti-Cancer Activity of Cucurbitacin IIa
(East Carolina University, 2012)
Cancer is a debilitating disease resulting from uncontrolled proliferation. One major treatment strategy for cancer is the application of chemotherapeutic drugs which kill cancer cells. Cucurbitacins are a new family ...
