Do Neonicotinoid Pesticide Seed Coatings Pose a Hazard to Seed-eating Birds?

Treating or “dressing” of seeds with pesticides is a commonly used method to enhance crop yield in agriculture.  Regrettably, such treated seeds can be ingested by wildlife, and depending on the extent of exposure, can cause adverse effects.

Genomic and Behavioral Effects of the Neonicotinoid Imidacloprid in Birds Exposed Through Pesticide-Coated Seeds

The Challenge: Neonicotinoid pesticides act as agonists of nicotinic acetylcholine receptors (nAChRs) and are designed to be lethal to insects while theoretically posing little to no threat to vertebrates. The perceived safety of neonicotinoids has led to a sharp increase in their use in the United States and globally, since they were first introduced in 1994. The use of the neonicotinoid...

Groundwater Response to Earthquakes

Did you know? Earthquakes can affect groundwater levels?

We often see a response to large (and sometimes not so large) earthquakes in groundwater levels in wells. The USGS maintains a network of wells for monitoring various things like natural variability in water levels and response to pumping and climate change across the U.S.

Edwin B. Forsythe National Wildlife Refuge, New Jersey Study SIte
March 26, 2018

Recent research shows that sediment budgets of microtidal marsh complexes on the Atlantic and Pacific coasts of the United States consistently scale with areal unvegetated/vegetated marsh ratio (UVVR) despite differences in sea-level rise, tidal range, elevation, vegetation, and stressors. This highlights UVVR as a broadly applicable indicator of microtidal marsh stability.

 The purpose of the multibeam echosounder surveys was to map the bathymetry and backscatter intensity of the sea floor of the valley, providing a framework for geologic, oceanographic, and geochemical studies. The data from the three surveys are combined to produce grids of bathymetry and backscatter intensity at 12-m resolution that cover the entire valley and the head of the Hudson Canyon.

Development and evaluation of a record extension technique for estimating discharge at selected stream sites in New Hampshire
