Description
Summary:An identification database for seeds in coastal habitats at La Pérouse Bay, Manitoba, Canada, was developed using the DELTA (DEscriptive Language for Taxonomy) format and the program INTKEY. The database should be applicable throughout the coastal lowlands of the Hudson Bay and James Bay regions as similar plant assemblages are present. The database, based upon morphological characteristics and also incorporating ecological information, was used to identify seed specimens found in soil cores and seed traps. The most useful characters for identifying seeds were seed length, seed width, and seed shape. The database is available on the World Wide Web at http://prod.library.utoronto.ca/polyclave/. The seed flora is also documented in the form of a checklist, the first one published for the La Pérouse Bay region; this checklist is also applicable to other coastal areas in the Hudson Bay lowlands.Key words: Arctic, DELTA, floristics, identification, seed morphology.
