Living in a toxic world: Mechanisms of internal salt-sensing in C. elegans

Animals are exquisitely sensitive to salt concentrations in both their external and internal environments. While we now have a good understanding of how we taste salt, the mechanisms by which internal salt levels are sensed remain poorly described. This talk will describe recent work from the lab on the identification of a new pathway by which a single gut neuron in C. elegans detects ingested salts and protects the animal against high salt stress.

Hold the Salt: Salinity Influences Structure and Function of Streams Across North America

Most inland waters are defined by their low salinity relative to the oceans. However, both geological and anthropogenic processes can lead to freshwater salinization. This talk will summarize work done by Eric Moody and his research students at Middlebury College using ecological stoichiometry as a framework to study the causes and consequences of freshwater salinization in streams and rivers across North America.
