Stratigraphic Diagramming is here!

The Neotoma Explorer web application has been updated and now features interactive stratigraphic diagramming. When viewing a pollen dataset, select the "Diagram" tab to try out the new tool. Users may customize the y-axis, taxa grouping, and 5x exaggeration options. Also, mousing over the plot lines will display the underlying abundance data values.

New paper on age-model uncertainty in late Quaternary pollen cores is out!

A paper by Jessica Blois, Jack Williams, Eric Grimm, Steve Jackson, and Russ Graham has just been published in Quaternary Science Reviews. This paper uses the Neotoma database to assess the amount of temporal uncertainty in late Quaternary pollen cores from eastern North America. The authors then identify particularly well-dated and well-sampled sites ('benchmark' sites), and use them to update the age-models of nearby, non-benchmark sites. Read the paper here (subscription required) or e-mail Jessica Blois for a reprint.

Taxonomic Name Resolution and spellchecking for plant names

The Taxonomic Name Resolution Service (TNRS) is a new web application for checking spelling errors and currently accepted taxonomic plant names. It uses a fuzzy matching algorithm to find misspelled names. Lists of up to 5000 names can be submitted at a time by pasting the names into an online form. The website is here: Taxonomic Name Resolution Service

Read a recent article about TNRS in Nature.

Neotoma database highlighted in Trends in Ecology and Evolution

A recent paper by Fraser J. G. Mitchell entitled Exploring Vegetation in the Fourth Dimension (TREE, vol. 26, issue 1, January 2011) discusses pollen databases and the incorporation of the Global Pollen Database into Neotoma.

UK Study on Scientific Openness Announced

The Royal Society of the United Kingdom to conduct study on openness in science. The study, which is particularly focused on data sharing, is seeking input from academia, business, and industry in a "call for evidence." See http://royalsociety.org/news/Royal-Society-launches-study-on-openness-in-science/ for details.

Eos Meeting Report Published!

Neotoma held a 4-day conference in September at UW-Madison to launch the next development phase of Neotoma. 54 people from 10 different countries met to form working groups, discuss goals and priorities, learn about the progress of the database and website, and provide feedback about near and long-term database and website goals. See the accompanying Meeting Report in Eos (8 February 2011, Vol 92, No. 6, Page 48) for additional details.

Tilia Training Workshops in UK and France, May 2011

9-11 May 2011, Liverpool, England 16-18 May, Aix-en-Provence, France The new all-Windows version of Tilia was released in January 2011. This version includes the spreadsheet and graphics in a single program and includes many new enhancements, such as a component for generating and viewing age models. The program can also carry out stratigraphically constrained (and unconstrained) cluster analysis. The program is also designed to be compatible with the Neotoma Paleoecology Database, and will be used by Neotoma data stewards for data entry. It has forms for metadata, including site data, core data, geochronologic data, age models, contacts, and publications. The Neotoma Paleoecology Database is a multiproxy paleodatabase for the Quaternary and Pliocene. Constituent databases include the European Pollen Database and the North American Pollen Database. What will be covered: The Tilia training sessions will cover all aspects of the Tilia program, including data entry, metadata entry, age-model construction, cluster analysis, and construction and editing of pollen diagrams. The workshop will also provide an introduction to the Neotoma Paleoecology Database—how to use the website tools as well as make simple queries in Access to the full database. What to bring: Participants should bring a laptop computer and have administrative rights to install new software. The newest version of Tilia will be distributed to those who have not yet obtained it. Having Access installed is recommended, but not required. Time will be allotted for participants to work with their own data, which they should bring. Costs: There will be no registration fee. However, participants are responsible for their own travel, lodging, and meals. Recommendations for lodging will be made in a future announcement. Please reply (Richard.Bradshaw@liv.ac.uk) if you think you might come and indicate whether you choose Liverpool or Aix. We need a rough idea of numbers for planning. You will have to pay for travel and accommodation but we hope to subsidise some of the on-site costs. There are several cheap flights to Liverpool or Manchester airports and we can organize budget accommodation. Practical details and registration forms will be sent later. Please pass this on to interested colleagues.
