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.

TaxaMapper is a web application that enables you to map occurrences of taxa from the Neotoma database at different time periods. Create multiple layers of taxon versus time, combine them into new layers with AND/OR operations, and customize layer symbology to visually analyze spatiotemporal patterns. Additional features coming soon include search wildcards (e.g. Bison*) and minimum pollen abundance thresholds.

Several of us (Eric, Jessica, Brian and myself) contributed to a general article on databases in veretbrate paleontology which has been submitted to the Journal of Vertebrate Paleontology for publication. Our contribution featured FAUNMAP and Neotoma.

The revised age models for late Quaternary pollen sites in eastern North America are now available! A zip file containing the age models and additional information can be downloaded in the 'Documents' section of the Neotoma website. If you have any questions or feedback, please contact Jessica Blois or Jack Williams.

The new pending data repository provides access to data that have been sent to Neotoma but not yet incorporated into its relational database. Files here include new author submissions awaiting processing by Neotoma data stewards as well as miscellaneous datasets that do not yet fit into the Neotoma database structure. The repository provides search and sortable browsing of datasets via their basic metadata.
