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.

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.

Pamela Pelletier will be hosting this event at the LTRR. This activity is reserved for a specific group and designed to introduce high school students to dendrochronology.

Megafires, climate, and future forests

Wildfires of uncharacteristic severity interact with climate change and other disturbances to alter dry pine forests in western North America and the Mediterranean Basin. These fires present challenges for society and for the sustainability of ecosystems. While there are many differences between regions and nations, there are opportunities for comparative studies to assess current megafires and forecast future ecosystem change.
