Alterations in C:N ratio to understand plant metabolic pathways in response to pressure from goat grazing in the invasive species: Rhamnus cathartica, Vivian Marchan
The high fecundity and high germination rates of Rhamus cathartica serves the species to out-compete regional plant native species. Its high abundance in deciduous forest ecosystems forces species that are unable to utilize R. cathartica as...

Chemically imaging bacteria with super-resolution SERS on ultra-thin silver substrates, Aeli P. Olson, Kelsey B. Spies, Anna C. Browning, Paula A.G. Soneral, and Nathan C. Lindquist
Plasmonic hotspots generate a blinking Surface Enhanced Raman Spectroscopy (SERS) effect that can be processed using Stochastic Optical Reconstruction Microscopy (STORM) algorithms for super-resolved imaging. Furthermore, by imaging through...
Male and female parental care in the golden-rumped euphonia (Euphonia cyanocephala), Zachary Wright, Jeff Port, and Harold F. Greeney
A single nest of the Golden-rumped Euphonia (Euphonia cyanocephala) was filmed for 72 hours near the Yanayacu Biological Station in Ecuador located in tropical montane forest. Recording was between 15-21 February 2014. We report the first o...

Modeling leptin receptor insensitivity by comparing how leptin or leptin receptor mutations in mice affect body weight, basal metabolism, body temperature and feeding behaviors, Jessica Patton and Teresa F. DeGolier
Leptin, a protein hormone produced principally in adipose tissue, plays a major role in the regulation of food intake, hunger, satiety and metabolism. Most obesity is likely the result of the body's resistance to leptin. The purpose of this...
