Plant Functional Traits of Carapa guianensis, a Widespread Tropical Tree, Adapted to Local Climate Conditions at Two Elevations in Costa Rica
(2019-04-29)
Tropical rainforests are among the most biodiverse ecosystems in the world. However, plant species occurrences are highly dependent on localized topography, elevation, and climate. Convergent evolution has been studied ...
Behavioral Factors Governing the Extinction of Ambiguous Threat Cues
(2019-04-22)
The purpose of this experiment was to examine the cognitive mechanisms by which an animal uses associations to learn about temporally ambiguous aversive events. Traditionally, associative learning using forwards conditioning, ...
The Effects of Salinity and Pharmaceuticals on the Physiology of the Sheepshead Minnow (Cyprinodon variegatus)
(2019-04-22)
Natural and anthropogenic stressors in the environment, such as salinity and pharmaceuticals, may affect fishes in sublethal ways measurable through non-invasive swim tunnel respirometry. This method quantifies aerobic ...
Regulation of ADV-1 Protein Rhythms by the Transcription Factor CSP-1 in Neurospora crassa
(2019-04-23)
The circadian clock regulates the rhythmic expression of roughly half of the eukaryotic genome at the level of mRNA abundance. However, little is known about how rhythmic phase is regulated (Delaunay & Laudet, 2002). ...
Role of Lymphatics in Renal Sodium Handling: Implications for Hypertension
(2019-04-19)
Hypertension is the leading risk factor for cardiovascular diseases and strokes [1]. A portion of these patients exhibit SSHTN with high cardiovascular risk and are more difficult to pharmacologically control. The etiology ...
Lobbying Exposure and Committee Preferences in the United States Congress
(2019-04-22)
Lobbying has been an important part of the U.S. political landscape for over a century. A rich variety of literature in economics and finance has shown that lobbying efforts aimed at congressional representatives can affect ...
Development of Anti-Fouling Materials for Blood-Contacting Devices
(2019-04-25)
The safety and efficacy of blood-contacting medical devices is hindered by thrombosis upon implantation in the body. Silicones and polyurethanes (PUs) are commonly used for hemodialysis catheters and other blood-contacting ...
Impact of Polymer Architecture on PCL-DA/PLLA Semi-IPN Properties
(2019-04-26)
Cranio-maxillofacial (CMF) bone defects are most commonly treated with autografts despite their many limitations. Namely, the rigid autografts are difficult to shape and fit into complex defect geometries, resulting in ...
Trust in the Digital Age: Friends, Justice, and the Good Life
(2019-04-19)
A more complex definition of trust is required to better understand the Aristotelian virtues of friendship and justice, especially in the digital age. Within this argument, I develop and make use of two distinct notions, specific ...
Transcriptome Assembly and Characterization of the Benthic Annelid Paramphinome jeffreysii
(2019-04-23)
Species of the phylum Annelida have been essential as model organisms in the studies of biology, neurobiology, evolution, ecology, and phylogenomics. Prior work using genomics and transcriptomics has provided new insights ...
