Interactive effects of temperature and glyphosate on the behavior of blue ridge two‐lined salamanders, Eurycea wilderae
The objective of the present study was to evaluate the potential interactive effects of stream temperatures and environmentally relevant glyphosate‐based herbicide concentrations on movement and anti‐predator behaviors of larval Eurycea wilderae (Blue Ridge two‐lined salamander). Larval salamanders were exposed to one of four environmentally relevant glyphosate concentrations (0.00 µg a.e./L, ...

Surfactant-Enhanced Desorption of Atrazine and Linuron Residues as Affected by Aging of Herbicides in Soil
Abstract In the present work, we studied the efficiency of two surfactants, one anionic (SDS) and other non-ionic (Triton X-100), in the desorption of atrazine and linuron after 0, 3, and 9 months of soil-herbicide aging time. Batch desorption studies were conducted in soil-water and in soil-water-surfactant systems. The kinetic pattern of desorption was biphasic, a slow desorption following an ...

Distribution of arsenic and other minerals in rice plants affected by natural straighthead
Because of the inconsistency and unpredictability of naturally occurring straighthead, arsenical herbicides are sometimes used to induce straighthead-like symptoms to study this sterility disorder. In 2005, an outbreak of naturally occurring (nonchemically induced) straighthead in rice (Oryza sativa L.) study fields in Stuttgart, AR provided an opportunity to examine the role of minerals in this ...
