Palynological Databases: Hands-on Computer Workshop will be held October 19-20 in conjunction with the 46th Annual Meeting of the American Association of Stratigraphic Palynologists in San Francisco. This workshop will provide training in the use of various software packages with application to palynology, with emphasis on the Neotoma Paleoecology Database, but also including Tilia, RNeotoma, an R package for Neotoma, and the Neotoma Application Programming Interface. For more information please visit the workshop webpage.

The early view version of Model systems for a no-analog future: species associations and climates during the last deglaciation has just been published online (Williams et al, 2013, in a special issue of the Annals of the New York Academy of Sciences). With global climate change, Earth ecosystems may be moving into novel states that have no modern analogs. Thus, predicting and modeling the behavior of these ecosystems present major challenges. This paper explores model systems from the last deglaciation that also have no modern analogs and how these may help understand future ecosystem response. The paper, which utilizes pollen data from Neotoma, emanates from a workshop "Climate Change and Species Interactions: Ways Forward" held at the Cary Institute of Ecosystem Studies in November, 2012.

A report by Suzette Flantua et al. on the status of and updates to the Latin American Pollen Database (LAPD) appears in the August 2013 issue of PAGES News. LAPD is a Neotoma constituent database.

This workshop aims to develop strategies for updating chronologies in a semi-automated manner for paleo databases given new criteria, for example a new radiocarbon calibration curve or revised ages for stratigraphic/biostratigraphic markers (e.g. tephras). Applications for attendance now being accepted. Click here for more information.

Simon Goring has developed an R package to use the new API tools to interface with the Neotoma Paleoecology Database directly from R. Great job by Simon! Check the package out here.

A paper by Jessica Blois, Jack Williams, and co-authors is now available online early at Ecography (link). This paper paired fossil pollen assemblages across eastern North America from the Neotoma database with paleoclimatic simulations to model the climatic drivers of fossil pollen dissimilarity across space over the past 21,000 years. We found that the set of climate variables associated with dissimilarity between fossil pollen assemblages across eastern North America changed over the past 21,000 years. Higher magnitudes of climate change between time periods meant lower prediction strength when projecting spatial models of community dissimilarity to different time periods.
