Risk Assessment and Behavioral Choices of Larval Anurans (Lithobates Sphenocephalus)
(2011-04)
Larval anurans assess risk and make behavioral choices to avoid predation. Since antipredator behaviors may reduce foraging opportunities, prey behavioral decisions can be constrained by a tradeoff between survival and ...
Experimental evidence for predator learning and Müllerian mimicry in Peruvian poison frogs (Ranitomeya, Dendrobatidae)
(East Carolina University, 2013)
Poison frogs are characterized by bright coloration, striking patterns, and toxicity; they have thus become a classic example of aposematism. Ranitomeya imitator mimics three congeneric model species (R. fantastica, R. ...
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 ...
Are Marine Migrations of Striped Bass Genetically Pre-determined? : An investigation of Albemarle Sound-Roanoke River Striped Bass Migratory Patterns
(East Carolina University, 2010)
Striped bass, Morone saxatilis, is one of the most thoroughly studied anadromous fish species in the United States, with records governing the management of the species dating back to the late 1600s. However, management ...
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 ...
Developing a Panel of Microsatellite Markers for Common Moorhen (Gallinula chloropus) as a Research Tool for Population Studies
(East Carolina University, 2013)
The common moorhen (Gallinula chloropus) sometimes exhibits brood parasitism - a parent manipulating a conspecific host to raise its offspring, relieving the parent of the encumbrance of parental investment. It has been ...
IS PREDATION BY TURTLES SUFFICIENTLY STRONG TO AFFECT BIODIVERSITY WITHIN FISHLESS PONDS?
(East Carolina University, 2011)
Ecologists have long known that predation can have a strong effect on the diversity and abundance of prey in ecological communities. Much evidence on the importance of predation in aquatic systems has stemmed from studies ...
Cryptic Seed Heteromorphism in Packera tomentosa (Asteraceae) : Differences in Seed Mass Characteristics and Germination
(East Carolina University, 2012)
Germination requirements of seeds can dictate when and where plant offspring establish. Microsites available for germination vary spatially and temporally in factors such as temperature and moisture; thus, the production ...
Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
(East Carolina University, 2012)
The biodiversity of local communities is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf ...
Predator Out of Place : The Differential Impacts of Native and Non-native Crayfish on Bufo Tadpoles
(East Carolina University, 2010)
Predators have been shown to alter important fitness components (larval period, mass at metamorphosis, and overall survivorship) of larval anurans. Uncommonly studied predators of tadpoles include crayfish. Both native and ...
