ABIeS: A database for softwood identification

Résumé

Softwoods constitute an important part of the plant macro-remains that are found within the Carboniferous to the most recent fossil deposits. Their taxonomical study is mostly made possible thanks to classical references (Philips 1948, Greguss 1955, Esteban 2004, Philippe & Bamford 2008). As for hardwoods, in addition to similar standard publications, a dedicated database has started being developed seven years ago (Insidewood - Wheeler 2011). Today Insidewood constitutes a very useful and indispensable tool, in constant development, which allows online identification for extant and fossil hardwoods. Despite their abundance in fossil deposits, no tool dedicated to softwoods has been developed yet. To fill this gap, we initiated the implementation of a softwood database, ABIeS, on the biodiversity collaborative management platform Xper3 (Ung et al. 2010). The descriptive model is mainly based on IAWA list of softwood features (IAWA committee 2004) but we also propose original features linked for instance to cell size and cross-field characteristics. As a first step, we tried as much as possible to illustrate the softwoods diversity using local resources. Therefore, extant species were chosen among the one hosted at the MNHN-xylarium, Paris, whereas fossil species where chosen from the collection Boureau (UPMC, Paris). We finally carried a global analysis of the database in order to better understand the softwood variability regarding systematics and ecology. This project, although initiated in our laboratory in Paris has a collaborative aim. We invite all the researchers who are interested by the wood anatomy of extant and fossil conifers to join us.
