    Chemical profile of the North American native Myriophyllum sibiricum compared to the invasive M. spicatum Michelle D. Marko a,b,*, Elisabeth M. Gross c, Raymond M. Newman a, Florence K. Gleason b a University of Minnesota, Department of Fisheries, Wildlife and Conservation Biology, 1980 Folwell Avenue, St. Paul, MN 55108, USA b University of Minnesota, Department of Plant Biology, 1445 Gortner Avenue, St. Paul, MN 55108, USA c Limnological Institute, University of Konstanz, PO Box M659, 78457 Konstanz, Germany Received 7 September 2006; received in revised form 10 August 2007; accepted 27 August 2007 Available online 2 September 2007 Abstract Myriophyllum spicatum L. is a nonindigenous invasive plant in North America that can displace the closely related native Myriophyllum sibiricum Komarov. We analyzed the chemical composition (including: C, N, P, polyphenols, lignin, nonpolar extractables, and sugars) of M. spicatum and M. sibiricum and determined how the chemistry of the two species varied by plant part with growing environment (lake versus tank), irradiance (full sun versus 50% shading), and season (July through September). M. spicatum had higher concentrations of carbon, polyphenols and lignin (C: 47%; polyphenols: 5.5%; lignin: 18%) than M. sibiricum (C: 42%; polyphenols: 3.7%; lignin: 9%) while M. sibiricum had a higher concentration of ash under all conditions (12% versus 8% for M. spicatum). Apical meristems of both species had the highest concentration of carbon, polyphenols, and tellimagrandin II, followed by leaves and stems. Tellimagrandin II was present in apical meristems of both M. spicatum (24.6 mg gÀ1 dm) and M. sibiricum (11.1 mg gÀ1 dm).

  • Aquatic Vascular Plant Species Distribution Maps
    Appendix 11.5.1: Aquatic Vascular Plant Species Distribution Maps These distribution maps are for 116 aquatic vascular macrophyte species (Table 1). Aquatic designation follows habitat descriptions in Haines and Vining (1998), and includes submergent, floating and some emergent species. See Appendix 11.4 for list of species. Also included in Appendix 11.4 is the number of HUC-10 watersheds from which each taxon has been recorded, and the county-level distributions. Data are from nine sources, as compiled in the MABP database (plus a few additional records derived from ancilliary information contained in reports from two fisheries surveys in the Upper St. John basin organized by The Nature Conservancy). With the exception of the University of Maine herbarium records, most locations represent point samples (coordinates were provided in data sources or derived by MABP from site descriptions in data sources). The herbarium data are identified only to township. In the species distribution maps, town-level records are indicated by center-points (centroids). Figure 1 on this page shows as polygons the towns where taxon records are identified only at the town level.

  • Elodea Genus: Egeria Or Elodea Family: Hydrocharitaceae Order: Hydrocharitales Class: Liliopsida Phylum: Magnoliophyta Kingdom: Plantae
    Elodea Genus: Egeria or Elodea Family: Hydrocharitaceae Order: Hydrocharitales Class: Liliopsida Phylum: Magnoliophyta Kingdom: Plantae Conditions for Customer Ownership We hold permits allowing us to transport these organisms. To access permit conditions, click here. Never purchase living specimens without having a disposition strategy in place. The USDA does not require any special permits to ship and/or receive Elodea except in Puerto Rico, where shipment of aquatic plants is prohibited. However, in order to continue to protect our environment, you must house your Elodea in an aquarium. Under no circumstances should you release your Elodea into the wild. Primary Hazard Considerations Always wash your hands thoroughly before and after you handle your Elodea, or anything it has touched. Availability Elodea is available year round. Elodea should arrive with a green color, it should not be yellow or “slimy.” • Elodea canadensis—Usually bright green with three leaves that form whorls around the stem. The whorls compact as they get closer to the tip. Found completely submerged. Is generally a thinner species of Elodea. Has a degree of seasonality May–June. • Egeria densa—Usually bright green with small strap-shaped leaves with fine saw teeth. 3–6 leaves form whorls around the stem and compact as they get closer to the tip. Usually can grow to be a foot or two long. Is thicker and bushier than E. canadensis. Elodea arrives in a sealed plastic bag. Upon arrival, this should be opened and Elodea should be kept moist, or it should be placed in a habitat. For short term storage (1–2 weeks), Elodea should be placed in its bag into the refriger- ator (4 °C).
