Highly resolved pressure measurements on the seafloor over New Jersey’s continental shelf reveal the pressure signature of nonlinear internal waves of depression as negative pressure perturbations. The sign of the perturbation is determined by the dominance of the internal hydrostatic pressure (p⁰Wh) due to isopycnal displacement over the contributions of...

Hop (Humulus lupulus L.) production recently has expanded across the United States to
include areas of the country that have not previously grown hop commercially. In June
2015, a grower in western North Carolina detected powdery mildew in a small (<0.5-ha)
yard during routine scouting. Characteristic signs of powdery mildew...

Predicting the net effects on the carbon and water
balance of semi-arid forests under future conditions depends
on ecosystem processes responding to changes in
soil and atmospheric drought. Here we apply a combination
of field observations and soil–plant–atmosphere modeling
(SPA) to study carbon and water dynamics in a regenerating
ponderosa...

Rationale:
The sampling of sequential, annually formed bone growth layers for stable carbon (δ¹³C values) and nitrogen (δ¹⁵N values) isotope analysis (SIA) can provide a time series of foraging ecology data. To date, no standard protocol exists for the pre-SIA treatment of cortical samples taken from fresh, modern, bones.
