Najas Guadalupensis (Spreng.) Magnus; Najas Southern Naiad Marina Najas Marina L.; Hollyleaf Naiad Naiads
A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Najas guadalupensis (Spreng.) Magnus; Najas southern naiad marina Najas marina L.; hollyleaf naiad Naiads Family: Hydrocharitaceae or Najadaceae Range: Southern naiad is found throughout the United States. Hollyleaf naiad is found in California, Arizona, Nevada, Utah and New Mexico. Habitat: Southern naiad inhabits still or slow-moving water in a broad range of substrates, including ponds, Najas lakes, reservoirs, canals, rice fields, and irrigation ditches. Grows at water depths of 3 to 15 ft and tolerates polluted guadalupensis water or slightly brackish water. Hollyleaf naiad inhabits fresh to brackish water marshes, ponds, lakes, slow-moving streams, canals, and irrigation systems Origin: Southern naiad is a common widespread native of North and South America. Hollyleaf naiad is native to the southwestern United States. Impacts: Both naiads are usually not considered weedy in natural habitats. The foliage and seeds are an important food source for wildlife, especially shorebirds and waterfowl. However, they can become troublesome in ditches, human-made ponds, and disturbed or controlled aquatic systems where populations can become locally dominant, forming dense submersed mats of vegetation. -

The Herbivorous Insect Fauna of a Submersed Weed, Hydrilla Verticillata (Alismatales: Hydrocharitaceae)
SESSION 5 Weeds of Aquatic Systems and Wetlands Proceedings of the X International Symposium on Biological Control of Weeds 307 4-14 July 1999, Montana State University, Bozeman, Montana, USA Neal R. Spencer [ed.]. pp. 307-313 (2000) The Herbivorous Insect Fauna of a Submersed Weed, Hydrilla verticillata (Alismatales: Hydrocharitaceae) C. A. BENNETT1 and G. R. BUCKINGHAM2 1 Department of Entomology and Nematology, University of Florida, and 2 USDA-ARS 1,2 Florida Biological Control Laboratory, P.O. Box 147100, Gainesville, Florida 32614-7100, USA Abstract Although relatively few insects have been reported to feed on submersed aquatic plants, field surveys on Hydrilla verticillata (L. F.) Royle for biological control agents have demonstrated that insect herbivores should be expected when surveying submersed aquatic plants in the native ranges. Beetles, or Coleoptera, especially the weevils (Curculionidae), are important herbivores. Weevils attack submersed plant species both when water is present and when water is absent during dry periods which leave the plants exposed. Pupal success appears to be the major determinant of weevil life cycle strategies. Donaciine leaf beetles (Chrysomelidae) attack the roots or crowns of submersed species, but their feeding and damage is difficult to determine. Leaf-mining Hydrellia flies (Diptera: Ephydridae) are diverse and common on submersed species. Other flies, the midges (Chironomidae), are also common on submersed species, but many utilize the plants only for shelter. However, midge larvae ate the apical meristems on the tips of hydrilla stems. Aquatic caterpillars (Lepidoptera: Pyralidae) are the herbivores most eas- ily observed on submersed species because of their large size and conspicuous damage, but their host ranges might be too broad for use as biological control agents. -

The Origin of Najas and Potamogeton. By Shigeru Miki. With 1 Plate and 3 Text-figures. ReceivedMarch 31, 1937. Introduction, It is a well known fact, that in water plants the reduction and simpli- fication of floral parts occurs very frequently probably in accordance with their aquatic habit. Najas and Potamogeton, both of which have apetalous flowers, are considered generally, merely on account of that fact, to be closely related. A closer examination shows however that the floral scheme is not similar. The flower of Potawogeton should be interpreted as a reduced inflorescence, so that it is nearly related with Synanthae or Pan- danales, while Na jas may be considered as a descendant of the ancient stock of submerged Ilydrocharitaceae. I wish to express here my sincere thanks to Prof. -
European Naiad: an Invasive Aquatic Plant Najas Minor
European Naiad: An Invasive Aquatic Plant Najas minor Description • Najas minor is an annual, rooted, submerged exotic aquatic plant originally from Europe. • Leaves are lime green, very slender and 1 ¾ inches long with 6-15 deep conspicuous teeth along the margin. Leaves are usually opposite each other with a wide base that tapers to a sharp tip. • The brittle, re-curved leaves branch profusely at the apex, giving N. minor a bushy appearance. • Small 1.5 – 3.0 mm fruits develop in the leaf axils. Fruits are slightly curved and have white ladder- like longitudinal rows. European Naiad Habitat European Naiad is a hardy species that is established in the alkaline waters of western Massachusetts. • N. minor has greater tolerance for turbidity and eutrophic conditions than other native Najas species, often driving them out of an area. • N. minor prefers slow moving waters including lakes and ponds but occasionally exists in rivers. Commonwealth of Massachusetts ~ Department of Conservation and Recreation ~ Office of Water Resources ~ Lakes and Ponds Program 1 Distribution Map Najas minor Reproduction European Naiad reproduces by both vegetative methods and from seed production. • Vegetatively, N. minor reproduces by stem fragmentation. Fragments often attach to boats, gear, wildlife or may drift to new locations and form pioneer colonies. • N. minor reproduces primarily from seeds. Small fruits develop in the leaf axils, and during late summer, the leaves become brittle and fragment. Impacts and Threats Posed by European Naiad European Naiad grows and reproduces rapidly, and often displaces native species, reduces biodiversity, hampers recreational uses, and reduces real estate and aesthetic values. -

Peredo*¤, Ursula M. King, Donald H. Les Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, Connecticut, United States of America Abstract The re-colonization of aquatic habitats by angiosperms has presented a difficult challenge to plants whose long evolutionary history primarily reflects adaptations to terrestrial conditions. Many aquatics must complete vital stages of their life cycle on the water surface by means of floating or emergent leaves and flowers. Only a few species, mainly within the order Alismatales, are able to complete all aspects of their life cycle including pollination, entirely underwater. Water- pollinated Alismatales include seagrasses and water nymphs (Najas), the latter being the only freshwater genus in the family Hydrocharitaceae with subsurface water-pollination. -

Phylogenetics and Molecular Evolution of Alismatales Based on Whole Plastid Genomes
PHYLOGENETICS AND MOLECULAR EVOLUTION OF ALISMATALES BASED ON WHOLE PLASTID GENOMES by Thomas Gregory Ross B.Sc. The University of British Columbia, 2011 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIRMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate and Postdoctoral Studies (Botany) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) November 2014 © Thomas Gregory Ross, 2014 ABSTRACT The order Alismatales is a mostly aquatic group of monocots that displays substantial morphological and life history diversity, including the seagrasses, the only land plants that have re-colonized marine environments. Past phylogenetic studies of the order have either considered a single gene with dense taxonomic sampling, or several genes with thinner sampling. Despite substantial progress based on these studies, multiple phylogenetic uncertainties still remain concerning higher-order phylogenetic relationships. To address these issues, I completed a near- genus level sampling of the core alismatid families and the phylogenetically isolated family Tofieldiaceae, adding these new data to published sequences of Araceae and other monocots, eudicots and ANITA-grade angiosperms. I recovered whole plastid genomes (plastid gene sets representing up to 83 genes per taxa) and analyzed them using maximum likelihood and parsimony approaches. I recovered a well supported phylogenetic backbone for most of the order, with all families supported as monophyletic, and with strong support for most inter- and intrafamilial relationships. A major exception is the relative arrangement of Araceae, core alismatids and Tofieldiaceae; although most analyses recovered Tofieldiaceae as the sister-group of the rest of the order, this result was not well supported. Different partitioning schemes used in the likelihood analyses had little effect on patterns of clade support across the order, and the parsimony and likelihood results were generally highly congruent.
