Preparing your sample collections for archiving: Q&A discussion about what you should be doing

Primarily an opportunity for question and answer, this forum will include a very brief refresher on the primary reasons for archiving specimens followed by review of procedures.

Blue Chip Interphase Tour

This is a tour designed for the Blue Chip Interphase Group. The group will gather in the lobby of the Bryant Bannister Tree-Ring Building at 3:50pm to begin the one hour tour at 4pm.

Low-frequency streamflow signal from cottonwood tree rings

Tree-ring reconstructions from ring widths of upland trees are a longstanding source of information on variability of streamflow.  Such trees sense variations in net precipitation in runoff-producing parts of a watershed.  While riparian trees are much less commonly applied in streamflow reconstruction, large multi-aged populations of riparian trees offer the opportunity to improve reconstructions of streamflow through alternative standardization methods and a direct pathway of response of growth to changes in stream level.
