Description

Molecular methods reveal new information on the range and recent history of four related and similar appearing species: Hydrilla verticillata, Egeria densa, Elodea canadensis, and Elodea nuttallii (family Hydrocharitaceae). We also distinguish monoecious from dioecious hydrilla for each of the hydrilla samples. We examined implications of the confirmed distribution relative to previous records and demonstrated the regional and national need for reverification of these species collected recently or as much as a half century ago.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 63 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Title Application of molecular techniques for identification of Hydrilla, Egeria, and Elodea (Hydrocharitacea)
Study Area Description Fresh and archived samples were acquired throughout the USA: about % 30 of the samples were from the Chesapeake Bay watershed. Herbarium samples were acquired with permission from the United States National Herbarium (US), George Mason University, Fairfax, Virginia (GMUF), North Carolina State University (NCSC), University of Florida (FLAS), University of Alabama (UNA), Missouri Botanical Garden (MO), Patuxent Research Refuge Herbarium, and Gabrielson Laboratory, Laurel, MD (PRR).
Design Description Premise of study: We apply molecular methods to reveal new information on the range and recent history of four related and morphologically similar species, Hydrilla verticillata, Egeria densa, Elodea canadensis, and Elodea nuttallii (family Hydrocharitaceae). We also distinguish monoecious from dioecious hydrilla for each of the hydrilla samples.
